Objective
To explore the surgical technique and effectiveness of autologous femoral head bone graft in total hip arthroplasty (THA) for Crowe type Ⅲ developmental dysplasia of the hip (DDH) with acetabular bone defect.
Methods
Between July 2012 and September 2015, 12 cases (12 hips) of Crowe type Ⅲ DDH with acetabular bone defect were included. Of the 12 patients, 2 were male and 10 were female, with an average age of 54.3 years (range, 37-75 years). The Harris score before operation was 41.08±7.90. The preoperative leg length discrepancy was 0.53-4.28 cm, with an average of 2.47 cm. Autologous femoral head bone graft and cancellous screw fixation were used in all cases to reconstruct acetabula in THA. Four cases were performed with subtrochanteric shortening osteotomy at the same time.
Results
All incisions healed by first intention. Twelve cases were followed up 1 year and 10 months to 5 years, with an average of 3.0 years. X-ray films showed that bone healing was observed in all cases at 6 months to 1 year after operation. There was no bone graft osteolysis, absorption, bone graft collapse, and acetabular prosthesis loosening. At last follow-up, the Harris score was 89.50±2.78, showing significant difference when compared with preoperative value (t=–25.743, P=0.003). The length discrepancy was 0-1.81 cm at last follow-up with an average of 0.76 cm.
Conclusion
Autologous femoral head bone graft is effective for Crowe type Ⅲ DDH with acetabular bone defect, which has advantages of restoring pelvic bone stock, obtaining satisfied prosthetic stability and mid-term effectiveness.
Objective To evaluate the effectiveness of arthroscopic Pushlock anchor fixation with iliac creast bone autograft in the treatment of recurrent anterior shoulder instability with critical bone defect. Methods The clinical data of 80 patients with recurrent anterior shoulder instability with critical bone defect treated by arthroscopic Pushlock anchor fixation with iliac creast bone autograft between January 2016 and January 2019 were retrospectively analyzed. The patients were all male; they were 18-45 years old at the surgery, with an average of 25 years old. The disease duration ranged from 3 months to 5 years, with an average of 2 years. The shoulder joint dislocated 3-50 times, with an average of 8 times. X-ray films, MRI, CT scans and three-dimensional reconstruction of the shoulder were performed before operation. The area of the anterior glenoid defect was 25%-45%, with an average of 27.3%. The shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score were used to evaluate the shoulder function before operation and at last follow-up. ResultsPatients were followed up 1-3 years, with an average of 2 years. No shoulder dislocation occurred again during follow-up. All partial graft absorption occurred after operation, CT scan showed that the graft absorption ratio was less than 30% at 1 week and 3 months after operation. CT three-dimensional reconstruction at 1 year after operation showed that all grafts had healed to the glenoid. The anterior glenoid bone defect was less than 5% (from 0 to 5%, with an average of 3.2%). At last follow-up, the shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score significantly improved when compared with preoperative ones (P<0.05). The shoulder mobility of external rotation in abduction at 90° of the affected side limited when compared with the healthy side [(6.7±5.1)°]. ConclusionArthroscopic Pushlock anchor fixation with iliac creast bone autograft has a good effectiveness in the treatment of recurrent anterior shoulder instability with critical bone defect. The method is relatively simple and the learning curve is short.
ObjectiveTo explore the effects of perioperative autologous platelet transfusion on postoperative complications and prognosis of adult cardiac surgery patient.MethodsUsing the method of systematic review of Cochrane Collaboration, we searched PubMed, Web of Science, EMbase, The Cochrane Library, CNKI and Wangfang databases, retrieving the literature from January 1970 to June 2020 to collect clinical randomized controlled trials on the effects of autologous platelet transfusion on complications and prognosis of adult cardiac surgery patients. The extracted valid data was analyzed by RevMan5.3 software.ResultsTen studies were included, with a total of 1 083 patients. The results of meta-analysis showed that there were statistical differences in the perioperative blood loss (MD=?195.15, 95%CI ?320.48-?69.83, P=0.002) and perioperative blood transfusion (MD=?0.88, 95%CI ?1.23-?0.52, P<0.001). There was no statistical difference in the death rate 30 days after the operation (RR=0.90, 95%CI 0.48-1.70, P=0.75), reoperations (OR=0.48, 95%CI 0.23-1.02, P=0.06), postoperative myocardial infarction (OR=1.29, 95%CI 0.48-3.51, P=0.61), postoperative infection (OR=1.71, 95%CI 0.89-3.29, P=0.11) or postoperative ICU retention time (MD=?0.31, 95%CI ?0.67-0.05, P=0.09).ConclusionPerioperative autologous platelet transfusion can reduce perioperative blood loss and blood transfusion in adult cardiac surgery patients, but has no significant impact onprognosis and postoperative complications, which indicates that perioperative autologous platelet transfusion is a safe and beneficial blood protection measure for patients undergoing cardiac surgery.
The sternum is the pivotal component of the thoracic cavity. It is connected with the clavicle and ribs on the upper part and both sides respectively, and plays an important role in protecting the stability of the chest wall. Sternal resection usually results in a large segmental chest wall defect that causes the chest wall to float and requires sternal reconstruction. This paper reports a 62 years male patient with thymic squamous cell carcinoma with sternal metastasis, who underwent thymotomy, sternal tumor resection and autologous lilum graft combined with sternal reconstruction by titanium plate after relevant examination was completed and surgical contraindications were eliminated. The patient was followed up for 6 months, the respiratory and motor functions were normal and the thoracic appearance was good.
ObjectiveTo generalize the application and prospect of computed tomographic angiography (CTA) in deep inferior epigastric artery perforator (DIEP) flap transfer for breast reconstruction.MethodsThe related literature using CTA for DIEP flap reconstruction of breast in recent years was reviewed and analyzed.ResultsPreoperative CTA can accurately assess the vascular anatomy of the chest and abdomen wall, precisely locating the perforator in the abdominal donor site, and identifying the dominant perforator; guide the selection of intercostal space to explore internal mammary artery and internal mammary artery perforator in the chest recipient vessels. It can also reconstruct the volume of the abdominal flap with reference to the size of the contralateral breast and pre-shape the abdominal flap, which are crucial to formulate the surgical plan and improve the reliability of flap.ConclusionPreoperative CTA has enormous application potential and prospects in locating donor area perforator, in selecting recipient vessels, and in evaluating breast volume for autologous breast reconstruction with DIEP flap.
ObjectiveTo explore the effect of hepatic outflow reconstruction with allograft vascular in ex-vivo liver resection and autologous liver transplantation.MethodThe clinical data of a patient with end-stage hepatic alveolar echinococcosis admitted to the Organ Transplantation Center of Sichuan Provincial People’s Hospital in August 2019 who underwent the ex-vivo liver resection and autologous liver transplantation combined with hepatic vein reconstruction with allograft vascular were analyzed retrospectively.ResultsThe patient, a 44-year-old female, was admitted to Sichuan Provincial People’s Hospital for “pain in the right abdomen accompanied by skin and sclera yellow staining for 6+ months and aggravated for 20+ d”. When the patient was admitted, the general condition was poor, such as hyperbilirubin and hypoproteinemia. The body mass was 45 kg and the standard liver volume was 852 mL. The hydatid lesions corroded the first and second hilum of the liver, the right hepatic vein and the posterior inferior vena cava. It was difficult to reconstruct the outflow tract of the hepatic vein in vivo, and it was extremely difficult to completely remove the hydatid lesions in vivo. After admission, the patient was generally in a good condition after the PTCD treatment, then after discussion and rigorous evaluation, the ex-vivo hepatectomy combined with autologous liver transplantation was required. The operative time was 15 h and the intraoperative blood loss was approximately 2 000 mL. After the operation, the routine treatment was performed, the antiviral treatment was continued, the international standardized ratio value was monitored at 1.5–2.5, and the anti-immune rejection drugs were not needed. The patient was transferred to the general ward on the 4th day after the operation, and there were no bile leakage, bleeding, infection and other complications. the result of postoperative pathological diagnosis was the alveolar echinococcosis. The re-examination of enhanced CT on 1 week after the operation suggested that the hepatic outflow tract of allograft vascular reconstruction was unobstructed, no stenosis and no thrombosis occurred. The patient was following-up at present.ConclusionsIn treatment of end-stage hepatic alveolar echinococcosis by autologous liver transplantation, reconstruction of hepatic outflow should be individualized. Allograft venous vessels could be used as ideal materials due to their advantages of matched tube diameter and length, no anti-rejection, and low risk of infection.
We reported a case of a six-year-old boy diagnosed of single ventricle, pulmonary atresia and interrupted inferior vena cava. After modified Blalock-Taussig shunt and bidirectional Glenn procedure, he received the Fontan procedure. The Fontan procedure was done through a unilateral thoracotomy, using an autologous pericardial conduit to connect hepatic vein and azygos vein. The result of short-term follow-up was satisfactory.
Objective
To summarize the methods, safety, and efficacy of the ex vivo liver resection followed by autotransplantation in the treatment of advanced hepatic alveolar echinococcosis (HAE).
Method
A retrospective analysis of clinical data and follow-up data in 21 cases who received ex vivo liver resection followed by autotransplantation in the treatment of HAE from February 2014 to December 2016 in West China Hospital was performed.
Results
All the patients successfully underwent ex vivo liver resection followed by autotransplantation and no death happened during operation. The median weight of remnant liver was 701.4 g (360–1 300 g), the average operation time were 13.6 h (9.4–19.5 h), the anhepatic phase time were 180–455 min with median of 314 min. The average of intraoperative blood loss were 2 379 mL (1 200–6 000 mL). The average of patients entered red blood cell suspension were 10.6 u (0–39.5 u), the average of fresh frozen plasma were 1 377 mL (0–6 050 mL) , of which 7 patients received autologous blood transfusion, with average of 1 578 mL (500–3 700 mL). The average of postoperative hospital stay were 23.5 days (4–51 days). Postoperative complications occurred in 12 patients during hospitalization, and 4 cases of postoperative complications were in grade Clavien-Dindo Ⅲ or above, 2 cases of grade Ⅴ (died). During the follow-up period, 19 patients were followed for a median of 16.2 months (3–38 months), no HAE recurrence or metastasis was found, only 1 patient were lost follow-up after surgery for 12 months. Massive ascites and hyponatremia were found in 1 patient who was diagnosis as left hepatic vein stenosis at the end of the 3 months after operation. The patient was cured after interventional treatment of hepatic vein stent implantation and angioplasty.
Conclusions
The ex vivo liver resection followed by autotransplantation provides radical treatment for patients with advanced HAE, but the surgery is difficult and has high risk of postoperative complications. The detailed preoperative evaluation, intraoperative pipeline reconstruction reasonably, and fine postoperative management can improve the patient’s survival, and reduce the rate of complications.
Objective To compare the effectiveness of arthroscopic osteochondral autologous transplantation (OAT) in the treatment of young and middle-aged patients with the articular cartilage injury. MethodsA clinical data of 43 patients (43 knees) with articular cartilage injury, who underwent OAT between January 2008 and August 2016, was retrospectively analyzed. There were 23 patients aged 20-40 years (young group) and 20 patients aged 40-60 years (middle-aged group). The difference in age between the two groups was significant (t=14.120, P=0.001). There was no significant difference in gender, body mass index, complications, affected side, lesion site, lesion area, and the International Cartilage Repair Society (ICRS) grade of cartilage injury between the two groups (P>0.05). The function of knee joint was evaluated by Lysholm score and International Knee Documentation Committee (IKDC) score during the follow-up. MRI examination was performed to observe the repair of both receiving and the donor sites. ResultsAll the incisions in the two groups were healed by first intention. All patients in the two groups were followed up with an average of 3.6 years (range, 2-8 years). At 2 years after operation, the Lysholm and IKDC scores were significantly improved in the two groups when compared with the preoperative scores (P<0.05). The Lysholm and IKDC scores in the young group were significantly better than those in the middle-aged group before operation and at 2 years after operation (P<0.05). However, there was no significant difference in the differences of the Lysholm and IKDC scores between pre- and post-operation between the two groups (P>0.05). The MRI examination at 2 years after operation showed that both receiving and the donor sites healed well in the two groups. ConclusionAccording to the texture, thickness, elasticity, and lesion area of the cartilage, arthroscopic OAT might be the first choice for the articular cartilage injury in middle-aged patients and can obtain the satisfactory short-term effectiveness.
Objective To explore the effect of “in situ first” ex vivo liver resection and autologous liver transplantation (ELRA) for end stage hepatic alveolar echinococcosis (HAE). Methods The clinicopathologic data of 85 end stage HAE cases were initially scheduled underwent ELRA from June 2019 to May 2022 in the Sichuan Provincial People’s Hospital were collected retrospectively. The included cases were operated under “in situ first” ERLA principle. The analyzed data included the final surgical style, operative time, time of anhepatic phase and intraoperative blood transfusion volume for ELRA cases. Results All the included 85 cases underwent radical HAE lesions resection and without perioperative death occurred. According to the principle of “in situ first”, 57 cases underwent HAE lesions resection combined vascular reconstruction without ex vivo liver resection (in situ resection group); 1 case underwent auxiliary partial autologous liver transplantation, and 27 cases underwent ERLA procedures (ELRA group). In the in situ resection group, the operative time was 210–750 min, （380±134）min, and the intraoperative blood transfusion was 0–3 250 mL with a median of 0 mL. In the ELRA group, the operative time was 450–1 445 min, (852±203) min, and the intraoperative blood transfusion was 0–6 800 mL with a median of 1 960 mL. The operative time and the amount of blood transfusion in the ELRA group were longer or more than those in the in situ resection group. The time of anhepatic phase for the ELRA group was 60–480 min, (231±83) min. On the 5th day after operation, except that the total bilirubin and direct bilirubin in the ELRA group were higher than those in the in situ resection group, the other indexes of liver function were similar between the two groups. The postoperative stay in ICU and the total postoperative hospital stay in the ELRA group were longer than those in the in situ resection group. Conclusions The advantage of “in situ first” ERLA principle for end stage HAE patients include resecting the HAE lesions radically without ex vivo liver resection and alleviating the hepatic ischemia and reperfusion injury. For the inevasible ELRA cases, “in situ first” principle could shorten the anhepatic phase and reduce intraoperative blood loss, and turn some cases to auxiliary partial autologous liver transplantation, which will reduce the risk of postoperative hepatic failure.
