ObjectiveTo investigate the clinical anatomy and application of free profunda femoral artery pedicled chimeric myocutaneous perforator flap in the defect reconstruction after radical resection of tongue carcinoma. MethodsBetween April 2011 and January 2016, 44 cases of tongue carcinoma underwent radical resection, and tongue defects were reconstructed by free profunda femoral artery pedicled chimeric myocutaneous perforator flaps at the same stage. There were 40 males and 4 females, with a mean age of 46.3 years (range, 32-71 years). The pathologic type was squamous cell carcinoma, which involved the lingual margin in 24 cases, the ventral tongue in 17 cases, and the mouth floor in 3 cases. According to Union for International Cancer Control (UICC) TNM staging, 16 cases were rated as T4N0M0, 11 cases as T4N1M0, 9 cases as T3N1M0, and 8 cases as T3N2M0. The course of disease ranged from 1 to 22 months (mean, 8.6 months). The size of perforator flap ranged from 8.5 cm×4.0 cm to 12.0 cm×6.5 cm, and the size of muscle flap ranged from 4.0 cm×3.0 cm to 7.5 cm×5.0 cm. The adductor magnus myocutaneous flap with a pedicle of (8.3±0.5) cm was used in 11 cases, and the gracilis muscle myocutaneous flap with a pedicle of (8.1±0.8) cm was used in 33 cases. The donor sites were sutured directly. ResultsAll 44 perforator flaps survived uneventfully, and the donor site healed well. The patients were followed up for 12 to 40 months (mean, 23.8 months). The reconstructed tongue had good appearance and function in swallowing and language. No local recurrence was found. Only linear scar was left at the donor sites. ConclusionThe free profunda femoral artery pedicled chimeric myocutaneous perforator flap can be harvested in various forms, and is an ideal choice to reconstruct defect after radical resection of tongue carcinoma.
ObjectiveTo investigate the feasibility of the free descending branch of lateral circumflex femoral artery perforator tissue flap (fascia flap plus skin flap) to repair large soft tissue defects of the extremities and its impact on the donor site.
MethodsBetween January 2013 and February 2015, 9 cases of large tissue defects of the extremities were repaired with the free descending branch of lateral circumflex femoral artery perforator tissue flap. There were 8 males and 1 female, aged from 13 to 56 years (median, 36 years). The causes included traffic accident injury in 6 cases and crushing injury by heavy object in 3 cases. Soft tissue defect located at the lower limbs in 7 cases and at the upper limbs in 2 cases, including 2 cases of simple tendon exposure, 2 cases of simple bone exposure, and 5 cases of tendon and bone exposure. After debridement, the soft tissue defect area ranged from 13 cm×7 cm to 20 cm×18 cm. The tissue flaps ranged from 14 cm×8 cm to 23 cm×19 cm. The donor site was directly sutured, scalp graft was used to cover the fascia flap.
ResultsAfter operation, partial necrosis of the skin grafting on the fascia flap occurred in 2 cases and healed after dressing change. Arterial crisis occurred in 1 case and the flap survived after anastomosis. The other tissue flaps survived and wounds healed by first intention. The skin grafting healed by first intention in 7 cases, by second intention in 2 cases. The patients were followed up 4-24 months (mean, 10 months). The appearance and function of the tissue flaps were satisfactory, only linear scar was observed at the donor site, which had less damage and no effect on walking.
ConclusionFree descending branch of lateral circumflex femoral artery perforator tissue flap can repair large soft tissue defect of the extremities. The donor site can be sutured directly, which reduces damage to donor site and is accord with the principle of plastic surgery.
ObjectiveTo summarize the effects of endovascular intervention and artificial graft bypass for the occlusive superficial femoral artery disease.
MethodsThe clinical data of 122 patients (136 limbs) with superficial artery occlusive disease underwent endovascular intervention or artificial graft bypass from January 2008 to April 2011 in this hospital were collected retrospectively. Age, TASCⅡgrading, condition of outflow tract, complications before and after procedures, hospital stay, primary patency rate, rate of amputation, and death rate were recorded.
Results①Seventy-four limbs of 64 patients were accepted percutaneous transluminal angioplasty and stent graft (PTA/S group), 62 limbs of 58 patients were accepted femoral popliteal artery artificial graft bypass (artificial graft bypass group). Compared with the artificial graft bypass group, the age was significantly older (P < 0.05), TASCⅡA or B lesions were more (P < 0.05), TASCⅡC or D lesions were less (P < 0.05), the limbs with one or three outflow tracts were more (P < 0.05) in the PTA/S group. The limbs with two outflow tracts, and the patients combined with diabetes or hypertension or diabetes and hypertension had no significant differences between these two groups (P > 0.05).②There was no perioperative mortality in two groups. Compared with the artificial graft bypass group, the average hospital stay was sifnificantly shorter (P < 0.05), the 3-year death rate after procedure was higher (P < 0.05), the rate of postoperative incision infection was lower (P < 0.05), the primary patency rate of 36-month after operation was lower (P < 0.05) in the PTA/S group. The rate of amputation, the primary patency rates of 6-, 12-, and 24-month after operation had no significant differences between these two groups (P > 0.05).
ConclusionsManagement of occlusive superficial femoral artery disease with femoral popliteal artery artificial bypass grafting exhibits a higher long term patency as compared with percutaneous stent graft. However, the hospital stay is longer than that in PTA/S group, and postoperative infection also occurres individually in artificial graft bypass group. Percutaneous transluminal angioplasty and stent graft has little trauma, faster recovery, shorter hospital stay, which is an important significance for the patients with too old or weak to accept femoral popliteal artery artificial graft bypass. But its long term patency rate needs to be improved.
Objective
To evaluate the safety and efficacy of the femoral arterial preclosure by purse-string suture for thoracic endovascular aortic repair (TEVAR).
Methods
From January 2013 to September 2016, TEVAR was performed on 40 patients with Standford type B aortic dissection. There were 34 males and 6 females aged 57.9±10.4 years. According to the surgical procedure, they were divided into a purse-string group (20 patients, 16 males, 4 females, aged 58.1±10.3 years), in which the patients received femoral arterial preclosure by purse-string suture and a convention group (20 patients, 18 males, 2 females, aged 57.7±10.8 years), in which the patients underwent conventional femoral cutdown. The outcomes and complications of two groups were evaluated.
Results
There was no in-hospital death and no paraplegia event. There was significantly shorter operation time (70.4±24.0 min vs. 100.8±35.6 min, P=0.003) and less blood loss (39.5±29.8 ml vs. 83.5±86.5 ml, P=0.038) in the purse-string group than those in the convention group. Femoral artery stenosis was observed in 3 patients (15.0%) in the convention group and none in the purse-string group during the follow-up of 1-36 (17.2±11.5) months with no statistical difference (P=0.231).
Conclusion
Using the femoral arterial preclosure by purse-string suture for TEVAR can save operation time, reduce intraoperative bleeding and decrease the approach-associated complications.
Drug addiction has been one of the serious social problems. The peripheral phlebitis caused by drug injection is common, but the occurrence of pseudoaneurysm with infection of femoral artery from injection injury was rarely reported in China. From January 1995 to March 1996, six cases of injury of femoral artery with infection from heroine injection were admitted. The characteristics of the injury were described. The therapeutic measures and details of attention to be needed were discussed. It was concluded that this type of injury was different from the injury caused in agricultural, industrial or traffic accidents. The treatment of choice depended upon the type of injury.
Objective To investigate the cl inical results of the flap pedicled with collateral branch of descendingrarus of lateral circumflex femoral artery with digital three-dimensional reconstruction technique for lower l imb soft tissue defects. Methods Between March 2009 and January 2010, 7 patients with lower l imb soft tissue defects were treated with free flap pedicled with collateral branch of descending rarus of lateral circumflex femoral artery. There were 6 males and 1 female with an age range from 6 to 51 years. They were injured by traffic accident (4 cases), or by object hit from height (3 cases). The locations were foot in 2 cases, ankle in 2 cases, and anterior tibia in 3 cases. The disease duration was 8 hours to 40 days (mean, 20 days). All the cases compl icated by exposure of tendons or bones. The areas of soft tissue defect ranged from 12 cm × 7 cm to 20 cm × 14 cm. Free flaps were transplanted at 4 to 16 days after symptomatic treatment. Before operation, all the flaps were designed with digital three-dimensional reconstruction technique. The size of flaps ranged from 15 cm × 9 cm to 22 cm × 16 cm The donor sites were closed directly in all cases. Results All the flaps survived. The wounds and incisions at donor sites healed by first intention. All the patients were followed up 6 to 12 months. The texture, appearance, and function of the flaps were satisfactory, and no compl ication occurred. All the flaps had protective sensation, which could meet the requirement of the daily l ife. The function of ankle was satisfactory with normal walk; the extension was 19-22° and the flexion was 30-36°. No obvious scar formed at donor sites. Conclusion The flap pedicled with collateral branch of descending rarus of lateral circumflex femoral artery has rel iable blood supply, easy operation, l ittle influence on the donor site, and high success rate with digital three-dimensional reconstruction technique. It is an excellent option for repairing lower l imb soft tissue defects.
Objective To investigate the vascular anatomy and the clinical application of type Ⅲ perforator flap based on the oblique branch of lateral circumflex femoral artery on skin soft tissue defect at the limbs. Methods Vascular anatomy of anterolateral thigh flap was performed on a 43-year-old male cadaver perfused with red latex, and the travel and perforating distribution of the oblique branches of lateral circumflex femoral artery were observed. A retrospective case series study was used to analyze the clinical data of 12 patients with skin soft tissue defects of the extremities admitted between January 2018 and September 2019, including 9 males and 3 females; aged from 18 to 65 years, with a median age of 32 years. The injury site included 7 cases of foot and ankle, 3 cases of calf, and 2 cases of hand. The wound size was ranged from 9 cm×7 cm to 28 cm×10 cm. The time from injury to operation was 1-2 weeks, with an average of 10 days. All patients were repaired with type Ⅲ perforator flap based on the oblique branch of lateral circumflex femoral artery, including 3 cases of single-leaf flap, 6 cases of double-leaf flaps, and 3 cases of tri-leaf flaps. The flap ranged from 15 cm×5 cm to 28 cm×10 cm. The donor site was directly sutured or repaired with local flap. The flap survival and complications were observed after operation. ResultsThe results of vascular anatomy showed that the lateral femoral circumflex artery sent out transverse branches, oblique branches, and descending branches. The oblique branches sent out multiple muscle perforating branches along the way, the perforating branches passed through the anterolateral femoral muscle, and the blood supply scope was the skin of the anterolateral femoral region. The clinical results showed that all flaps survived completely and the incisions healed by first intension. There was no complication such as vascular crisis. All 12 patients were followed up 3-12 months, with an average of 7 months. The appearance and texture of the flap were good. At last follow-up, according to the British Medical Research Council (BMRC) Society for neurological trauma standard, the sensory of the flap reached S2 in 9 cases and S3 in 3 cases. Linear scar remained in the donor area, without pain, pruritus, tactile allergy, and other discomfort. The patients and their families were satisfied. Conclusion Type Ⅲ perforator flap based on the oblique branch of lateral circumflex femoral artery is a reliable method for repairing the soft tissue defect of the limbs, with reliable blood supply, large cutting area, various types of perforator flaps.
ObjectiveTo discuss the effectiveness of femoral-femoral artery bypass grafting combined with transverse tibial bone transporting in treatment of lower extremity arteriosclerosis obliterans (ASO) or combined with diabetic foot. MethodsBetween March 2014 and June 2016, 9 patients with lower extremity ASO or combined with diabetic feet were treated with femoral-femoral artery bypass grafting and transverse tibial bone transporting. All patients were male, aged from 63 to 82 years with an average of 74.2 years. The disease duration of ASO was 1.5-22.0 months (mean, 10.5 months). All cases were severe unilateral iliac arterial occlusion, including 5 cases of the left side and 4 cases of the right side. There were 7 cases with superficial femoral and/or infrapopliteal artery disease. There were 7 cases of ASO and 2 cases of ASO combined with diabetic foot (Wagner grade 4); all the ASO were grade Ⅳ according to Fontaine criteria. All patients had rest pain before operation, and the ankle brachial index was 0.24±0.12. In femoral-femoral artery bypass grafting operations, artificial blood vessels were used in 7 cases and autologous saphenous vein were used in the other 2 cases. The tibial bone transverse transporting began on the 8th day after operation by 1 mm per day and once per 6 hours; after transported for 2-3 weeks, it was moved back. The whole course of treatment was 10-14 weeks. ResultsThe incision of tibial bone transverse transporting was necrotic in 1 case, and healed after dressing change. There was no obvious complication at the orifice of the needle. The other patients had no incision complication. The granulation tissue of foot wound was growing quickly after tibial bone transverse transporting, and the wound was reduced after 2-3 weeks. All the 9 patients were followed up 12-32 months (mean, 19 months). The ankle brachial index was 0.67±0.09 at 2 months postoperatively, which was significantly higher than that before operation (t=17.510, P=0.032). All the feet ulcer wounds healed and the healing time was 6.7-9.4 weeks (mean, 7.7 weeks). During follow-up, color Doppler ultrasound or CT examination revealed grafted blood vessel patency. The external fixator was removed at 12-14 weeks after operation. One case died of sudden myocardial infarction at 14 months after operation, and there was no lymphatic leakage. The patency rate of femoral-femoral bypass was 100% at 1 year after operation. The tibial transverse bone grafting healed with tibia at 4-6 months after operation. At last follow-up, the effective rate was 100%. ConclusionFemoral-femoral artery bypass grafting combined with transverse tibial bone transporting is an effective method in the treatment of lower extremity ASO or combined with diabetic foot.
ObjectiveTo investigate the effectiveness and safety of esophageal ultrasound-guided percutaneous femoral artery closure of ventricular septal defect (VSD).MethodsThe clinical data of 24 patients with congenital VSD in our hospital from March 2017 to December 2019 were retrospectively analyzed, including 6 males and 18 females, with a median age of 12 (3-42) years, weight of 32 (12-91) kg, and VSD diameter of 4 (3-7) mm. There were 3 patients with VSD combined with atrial septal defect.ResultsTwenty-four patients successfully underwent interventional closure of percutaneous femoral artery under esophageal ultrasound guidance, and the position and shape of the occluders were good. The operation time was 45 (39-54) min, and the waist size of the occluders was 7 (5-12) mm. Among the patients, 14 patients used symmetric ventricular occlusion devices, 8 patients used asymmetric ventricular occlusion devices, and 2 patients used ventricular occlusion muscle occluders. Small amount of residual shunt occurred in 2 patients after the operation and it disappeared 3 months after the operation. One patient with right bundle branch block, which disappeared after 1 week of observation. There were no complications such as occluder closure, pericardial effusion or valve regurgitation during the perioperative period. During the follow-up period [3-18 (9.25±5.04) months], no serious complication occurred.ConclusionTransesophageal ultrasound-guided transfemoral artery occlusion for VSD is simple and safe, and it avoids the damage of radiation and contrast medium. It has advantages over traditional percutaneous interventional occlusion therapy.
ObjectiveTo investigate the clinical efficacy and application value of percutaneous interventional treatment for structural heart diseases under guidance of ultrasound.MethodsThe clinical data of 1 010 patients with structural heart diseases treated by transcutaneous ultrasound-guided occlusion in our hospital from December 2, 2015 to December 31, 2019 were retrospectively reviewed, including 360 males and 650 females, aged 1-50 years. There were 692 patients of atrial septal defect (603 with central type, 9 combined with arterial catheter, 80 with ethmoid type), 116 patent foramen ovale, 25 ventricular septal defects (3 combined with atrial septal defect), 132 patent ductus arteriosus, 32 pulmonary valve stenosis (3 combined with atrial defect), 1 main pulmonary artery window, and 3 aneurysm rupture of aortic sinus. All patients were diagnosed by transthoracic echocardiography (TTE) before operation. Treatment was accomplished intraoperatively through TTE or transesophageal echocardiography (TEE) via the femoral artery or femoral vein. After operation, echocardiography, electrocardiogram and chest radiograph were reexamined.ResultsSatisfactory results were obtained in 1 005 patients, and 1 patient failed to seal the ventricular defect and was repaired under direct vision, occluder detachment occurred in 5 patients after operation (3 patients of atrial septal defects underwent thoracotomy for Amplatzer device and were repaired, 1 patient of atrial septal defects was closed after removing Amplatzer device, 1 patient of patent ductus arteriosus underwent thoracotomy for Amplatzer device and was sutured), mild pulmonary valve regurgitation occurred after balloon dilation in 2 patients with pulmonary stenosis, a small amount of residual shunt was found in 2 patients with ventricular defect, which disappeared after 3 months of follow-up, and 1 patient of right bundle branch block occurred and disappeared after 1 week. After follow-up of 1-24 months, 3 patients of ethmoidal atrial septal defect were reexamined with mild shunt. The occluder was in good position and the pressure difference of pulmonary valve was significantly reduced. There was no complication such as hemolysis, arrhythmia, embolism or rupture of chordae tendinae.ConclusionPercutaneous transfemoral artery and vein guided by TTE or TEE is safe and effective, with little trauma, no radiation or contrast agent damage, and has significant clinical efficacy and application values.
