ObjectiveTo evaluate the impact of the "key anatomical structure detection method" and "working length marking method" on the safety and efficacy of echocardiography-guided percutaneous closure of patent ductus arteriosus (PDA). MethodsPatients who underwent echocardiography-guided percutaneous PDA closure at Fuwai Hospital, Chinese Academy of Medical Sciences, with complete clinical data, between January 2016 and December 2021, were retrospectively analyzed. Patients were divided into a study group (procedure performed using both "key anatomical structure detection method" and "working length marking method") and a control group (procedures performed without these methods). Propensity score matching (PSM) was applied for 1∶1 matching between the two groups. The primary endpoint was procedure success at 30 days after procedure. Secondary endpoints included intraoperative echocardiography localization success, major and minor complication at 6 months after procedure, and days of hospital stay. Results A total of 273 patients were included, among which 141 were in the study group and 132 in the control group. Before PSM, all patients achieved procedure success. After PSM, 77 matched pairs (154 patients) were analyzed. The study group demonstrated a significantly higher intraoperative echocardiography localization success rate (98.70% vs. 50.64%, P<0.001) and shorter hospitalization duration at (4.10±1.98) d vs. (5.01±2.16) d (P=0.007). The 6-month minor complication rate was lower in the study group (0.00% vs. 6.49%, P=0.058). All patients were successfully discharged, with no cases of device embolization, infective endocarditis, or death observed during follow-up.Conclusion "Key anatomical structure detection method" and "working length marking method" are effective echocardiography-guided adjunctive methods that enhance the safety and efficacy of PDA closure. These approaches deserve further validation in prospective multicenter studies in the future.
ObjectiveTo summarize the treatment and experience of percutaneous transhepatic portal vein recanalization by endovascular approach for treatment of cavernous transformation of the portal vein (CTPV) in a child. MethodThe clinical data of a child with idiopathic CTPV who underwent percutaneous transhepatic portal vein recanalization by endovascular approach were retrospectively analyzed. ResultsWe described a novel percutaneous transhepatic portal vein recanalization approach that had successfully treated a child with idiopathic CTPV following a multidisciplinary team evaluation. The operation time was 1.5 h and blood loss was approximately 1 mL. The child recovered uneventfully at 9-month follow-up, without any clinical evidence of CTPV complications. ConclusionIn light of our successful management, we can envision that the portal vein recanalization is an important therapeutic supplement for treating CTPV and will result in a paradigm change.
Objective To explore the effectiveness of primary interventional revascularization combined with secondary perforator composite flap in the treatment of peripheral arterial disease (PAD) accompanied by soft tissue defects around the ankle. Methods Between January 2022 and January 2025, 12 patients with PAD and soft tissue defects around the ankle were admitted. Among them, there were 9 males and 3 females; their ages ranged from 52 to 82 years, with an average of 68.9 years. The causes of injury included 4 cases of traffic accident, 5 cases of falls, 1 case of falling from height, 1 case of foreign body puncture injury, and 1 case of electric shock injury. The infection duration ranged from 1 month to 35 years, with a median duration of 3.5 months. The wound size ranged from 5.5 cm×3.0 cm to 15.0 cm×9.0 cm. The ankle-brachial index (ABI) was 0.32±0.12. The visual analogue scale (VAS) score for pain was 3.3±0.5. Preoperative vascular stenosis assessment was performed in all patients, with primary intervention to dredge large and medium-sized arteries, followed by secondary repair of the wound using a perforator composite flap. The flap size ranged from 6.5 cm×4.0 cm to 16.0 cm×10.0 cm. The donor sites were sutured directly or repaired with skin grafts. After two stages of treatment, the effectiveness was evaluated by measuring ABI, observing flap survival and wound healing, assessing VAS scores, and American Orthopedic Foot and Ankle Society (AOFAS) scores. Results All 12 cases completed two stages of treatment; all patients were followed up after the second-stage treatment, with a follow-up period ranging from 7 to 28 months, with an average of 16.8 months. After the first-stage treatment, the skin temperature around the ankle was significantly higher than that before treatment, and the ABI increased to 0.71±0.07, with a significant difference (t=9.918, P<0.001). After the second-stage treatment, the blisters on the distal end of the skin flap occurred in 3 cases. The flaps survived and the wounds healed, with a healing time ranging from 10 to 14 days (mean, 11.8 days). The incisions at the donor site healed by first intention, and the skin grafts survived. The VAS score was 0.5±0.5 at 3 weeks, which was significantly lower than that before treatment (t=13.675, P<0.001). No infection recurrence occurred during follow-up. At 6 months after the second-stage treatment, the AOFAS score of the ankle joint ranged from 92 to 97, with an average of 94.7, all reaching excellent. Conclusion Interventional revascularization combined with perforator composite flap for staged treatment of PAD with ankle soft tissue defects can obtain good effectiveness, by unclogging the main blood vessels, improving lower limb blood supply, and improving the survival rate of the skin flap.
ObjectiveTo research the association between the prognostic nutritional index (PNI) and the prognosis of patients with malignant obstructive jaundice (MOJ) after interventional treatment. MethodsThe clinicopathologic data of patients with MOJ who were clinically diagnosed and underwent interventional treatment in the Affiliated Hospital of Southwest Medical University, from September 2018 to June 2021, were gathered retrospectively. The X-Tile statistical software was used to determine the optimal critical value of PNI before treatment, then the patients were allocated into the high PNI group (PNI was the optimal critical value or more) and low PNI group (PNI was less than the optimal critical value). The clinicopathologic characteristics of the two groups were compared. The Kaplan-Meier method was used to draw survival curve for survival analysis, and the Cox proportional hazards regression model was used to analyze the risk factors affecting the prognosis of patients with MOJ (the prognostic index was overall survival). ResultsA total of 205 patients were included in this study. The optimal critical value of PNI was 37.5. There were 154 cases in the high PNI group and 51 cases in the low PNI group, respectively. The proportions of the patients with biliary infection, CA19-9 ≥400 kU/L, hemoglobin <120 g/L, albumin <30 g/L, total bilirubin ≥300 μmol/L, and alanine aminotransferase <300 U/L were higher in the low PNI group as compared with the high PNI group (P<0.05). The median overall survival of patients in the high PNI group and low PNI group was 7.1 months and 3.6 months, respectively. The overall survival curve of the former was better than that the latter (χ2=18.514, P<0.001). The median follow-up time of 205 patients was 6.2 months, with a median overall survival of 5.3 months. The multivariate results of Cox proportional hazards regression model analysis showed that the probability of overall survival lengthening was increased for the patients with more times of PTCD, with stent implantation, with treatment for primary tumor, without metastasis, and with preoperative PNI ≥37.5 (P<0.05). ConclusionFrom the results of this study, preoperative peripheral blood PNI has a certain association with the prognosis of patients with MOJ after interventional treatment, and it is expected to be used to predict the prognosis of patients with MOJ in the future.

Methods : Fifteen cases with cesarean scar pregnancy performed with uterine artery interventional therapy were retrospectively analyzed from July, 2006 to December, 2007 in our hospital. Results : All cases were treated successfully by uterine artery chemotherapy and embolism. All cases were embolized with gelatin sponge after chemotherapy, and eight with spring ring additionally. Vaginal bleedings were stopped after uterine artery embolization. Gestation sacculi deflated obviously. Serum human chorionic gonadotrophin descended dramatically. There was no severe vaginal bleeding by curettage after interventional therapy. The villi, decidua, or placental tissues were observed with degeneration and necrosis by pathology. Conclusion : Uterine artery chemotherapy and embolization was proved to be a safe and useful procedure for preventing and controlling vaginal bleeding, diminishing the risk of curettage and avoiding the loss of uterus.
ObjectiveTo evaluate the occupational exposures and protective condition of medical staff in operating room for interventional therapy.
MethodsFrom September to November in 2014, 46 medical staff in the operating room for interventional therapy were adopted to complete the occupational exposures and protection situation survey. After that, we analyzed and scored all the questionnaires.
ResultsThe awareness of the medical staff about occupational exposures and occupational protection in the operating room was low; the awareness rates of doctors, nurses, and radiology technicians were 74.2%, 63.0% and 66.7%, respectively. The general condition of implement of occupational protection measures of the medical staff was bad, and the average rate of the doctors, nurses and radiology technicians was 51.3%, 43.9%, and 15.2%.
ConclusionThe implement rates of occupational protection measures of the medical staff in Operating Room for interventional therapy differ much from the awareness rates. The rates in doctors and nurses are higher than that in radiology technicians. We should strengthen the education of radiation damage and protection measures in doctors, and enhance the training of iatrogenic injuries related knowledge in clinical radiology technicians to reduce occupational hazards.
Early endovascular interventional therapy can effectively improve the prognosis of patients with acute ischemic stroke. Dual-source CT dual-energy scanning, as a new CT imaging technology developed rapidly in recent years, with its unique technical characteristics and advantages, shows potential and application prospects in early endovascular interventional therapy of acute ischemic stroke. This article discusses the value of dual-source CT dual-energy scanning in the early screening and evaluation, the identification of postoperative iodine contrast agent extravasation and secondary cerebral hemorrhage, and the prediction of prognosis of patients with early endovascular interventional treatment of acute ischemic stroke. The purpose is to provide a theoretical basis for better application of dual-source CT dual-energy scanning in early endovascular interventional treatment of acute ischemic stroke.
ObjectiveTo investigate the efficacy of subclavian-carotid transposition (SCT) in treating patients with proximal subclavian artery occlusive diseases who were unable to be intervened, such as failure of intervention, congenital malformation and unwillingness to intervention.MethodsA retrospective review of 19 patients with proximal subclavian artery occlusion who underwent SCT from May 2016 to December 2018 was done. There were 14 males and 5 females with an average age of 54.05±17.34 years. The advantages and disadvantages of SCT in the treatment of proximal subclavian artery occlusion were analyzed.ResultsAll patients achieved immediate remission of symptoms after surgery. The stenosis degree of the proximal subclavian artery decreased from 100.0%±0.0% to 12.7%±10.1% after surgery. The average blood pressure difference between the unaffected side and the affected side decreased from 11.95±10.60 mm Hg to 0.89±5.75 mm Hg (P<0.01). Peripheral nerve injury occurred in 7 (36.8%) patients. The in-patient cost of subclavian artery occlusion patients who received subclavian artery interventional therapy in our hospital during the corresponding period was 3 392.12 yuan higher than that of the SCT group in average (if eliminating the patients whose cost was far from the average value, the cost of interventional therapy was 4 812.01 yuan higher than that of the SCT group in average). During 1-3 years' follow-up, 6 patients with neurological complication relieved. One- and three-year patency rates were 100.0%. No perioperative stroke, death or re-operation happened.ConclusionSCT is an ideal process for the patients with subclavian artery occlusion who cannot accept subclavian artery interventional 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.
