Objective To evaluate the clinical outcomes of total cavopulmonary connection (TCPC) and bidirectional Glenn shunt for treating complex congenital heart diseases with single functional ventricles. Methods From January 2002 to May 2004, twelve children, who had complex congenital heart diseases with single functional ventricles, underwent TCPC and bidirectional Glenn shunt. Among them, male was 3 and female was 9. Ages were from 4 to 13 years and body weights were from 14 to 34 kilograms. The diseases included mitral atresia 1 case, tricuspid atresia 3 cases, right ectopic heart with transposition of great arteries 3 cases, D-transposition of great arteries 3 cases, and single ventricle 2 cases. Results Eleven children survived and one child died in acute renal failure 19 hours after operation. The hospital mortality was 8.3%. Four children had chyle-thorax postoperatively, and eight children had uneventful recovery. In the follow-up period, one child died 12 months postoperatively for pulmomary arteriovenous fistula, and there were no complications like severe arrhythmia, thrombosis and cerebral problems. Conclusions TCPC and bidirectional Glenn shunt are safe and effective techniques for treating complex congenital heart diseases with single functional ventricles, and the clinical outcomes are satisfactory. The key points for the successful operation are big enough cava-pulmonary anastomosis as well as aggressive perioperative management.
ObjectiveTo analyze the effect of modified B-T shunt for the treatment of complex congenital heart disease. MethodsWe retrospectively analyzed the clinical data of 150 B-T case times performed in 143 patients with complex congenital heart disease in Shanghai Xinhua Hospital between July 2006 and January 2013.There were 100 case times for male patients and 50 case times for female patients with age of 2-756 (20.17 ±80.37) months and weight of 4-63 (8.86 ±9.69) kg. ResultsThere were 5 in-hospital deaths (mortality at 3.50%). Three patients occurred abnormal bleeding (2.10%). Five patients (3.50%) performed the second B-T because of shunt occlusion. And the other patients recovered uneventfully. A total of 129 case times were followed up for 6-48 (14.38±10.05) months. Seven B-T case times (5.43%) were performed in 6 patients again because of shunt occlusion during the follow-up. Three patients died during the follow-up (mortality at 2.33%). A total of 88 patients of survival underwent corrective surgery or stage Ⅱ palliative surgery (68.22%). Main pulmonary artery have a significant increase in diameter during the follow-up(t=-15.18, P=0.00). Postoperative diameters of left pulmonary artery (t=-13.27, P=0.00), right pulmonary artery (t=-15.94, P=0.00), and right pulmonary artery (t=2.44, P=0.02) increased with statistical differences compared with preoperative values. Growth in ipsilateral pulmonary of B-T is better than that of the contralateral pulmonary (t=2.44, P=0.02). McGoon ratio increased significantly after B-T (t=10.10, P=0.00). Ejection fraction value was slightly lower than the preoperative value (t=2.77, P=0.00). Left ventricular mass index increased significantly compared with the preoperative value(t=-9.26, P=0.00). ConclusionsThe modified B-T shunt has been proved to be safe and effective in treating for complex congenital heart disease. It can significantly promote the development of pulmonary artery, especially the ipsilateral pulmonary of B-T. Small McGoon ratio and pulmonary atresia are the risk factors for limiting the further development of pulmonary. Appropriate diameter of B-T shunt choice according to preoperative pulmonary diameter and the weight of the patients is the basis to ensure successful operation and a good prognosis.
目的探讨防止限制性门腔静脉侧侧分流术后吻合口扩大的方法。方法对32例肝硬变门脉高压症患者行限制性门腔静脉分流术，术中采用不吸收缝线连续缝合门腔静脉吻合口前后壁形成自然的限制环，以防止术后吻合口的扩大。结果32例患者于术后3～36个月行彩超或螺旋CT检查，显示门腔静脉吻合口均无扩大； 术后再出血率为3.1%（1/32），肝性脑病发生率为6.3%（2/32）； 术后≤6个月时肝功能均有不同程度改善，与术前比较其差异有显著性（P＜0.001）； 全部病例随访6~49个月，随访率为100%。结论改良的限制性门腔静脉侧侧分流术是治疗肝硬变门脉高压症的有效方法。
Surgerical treatment has been used for portal hypertension over a hundred years, and has evolved from various portosystemic shunts to devascularizations and selective shunts. Selective shunting, which has the advantages of long-term prevention from recurrent variceal bleeding and maintenance of hepatic portal vein perfusion, has developed from single distal splenorenal shunt to various procedures including distal splenocaval shunt, coronary caval shunt, coronary renal shunt, etc. Selective shunting can also be achieved after reconstruction of spontaneous portosystemic shunt. Preoperative portal venous system CT angiography, intraoperative ultrasound Doppler and portal vein pressure measurements may provide patients with a more reasonable treatment of choice.
Objective To evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) combined with gastric coronary vein embolization for the treatment of liver cirrhosis with gastroesophageal varices hemorrhage, and evaluate its application value. Methods The data of 50 patients with liver cirrhosis who were treated with TIPS combined with gastric coronary vein embolization between June 2009 and January 2013 were retrospectively analyzed. According to Child-Pugh Liver Grade, the patients were divided into grade A liver function group (n=6), grade B liver function group (n=18), and grade C liver function group (n=26); according to the type of stent implantation, the patients were divided into covered stent group (n=29) and bare stent group (n=21). The 1-week and 1-, 3-, 6-, and 12-month postoperative liver function changes were compared, and the 2-year postoperative rebleeding rate, survival rate, stent restenosis rate, and hepatic encephalopathy incidence were observed. Results The success rate of surgery was 100.0% (50/50), and the success rate of emergency surgery was 100.0% (3/3) in 3 patients with active bleeding. The portal vein pressure decreased from (39.46±2.82) cm H2O (1 cm H2O=0.098 kPa) before the surgery to (25.62±2.13) cm H2O after the surgery, and the difference was statistically significant (P<0.05). In grade A and grade B liver function groups, and covered stent and bare stent groups, the differences between preoperative and postoperative liver function indexes were not statistically significant (P>0.05); in grade C liver function group, the 1-week, 1-month, 3-month postoperative values of alanine aminotransferase, aspartate aminotransferase, total bilirubin and direct bilirubin increased compared with the preoperative values, and the differences were statistically significant (P<0.05). The postoperative 2-year rebleeding rate was 12.0% (6/50), and the postoperative 2-year incidence of hepatic encephalopathy was 16.0% (8/50). The postoperative 2-year stent stenosis rate was 26.0% (13/50) in the 50 cases, which was 13.8% (4/29) in covered stent group and 42.9% (9/21) in bare stent group, respectively. The postoperative 2-year survival rate was 90.0% (45/50). Conclusions TIPS combined with gastric coronary vein embolization in the treatment of liver cirrhosis with gastroesophageal varices bleeding has the exact effect, low rebleeding rate, fewer complications, and can be repeated. The preoperative evaluation of patients’ liver function, the application of stent of diameter 8 mm, paying attention to the perioperative period and regular follow-up treatment are helpful to reduce or prevent the occurrence of hepatic encephalopathy, stent stenosis and other complications.
Objective To evaluate the feasibility of X-ray guided access to the extrahepatic segment of the main portal vein (PV) to create a transjugular extrahepatic portacaval shunt (TEPS). Methods 5F pigtail catheter was inserted into the main PV as target catheter by percutaneous transhepatic path under ultrasound guidance. The RUPS-100 puncture system was inserted into the inferior vena cava (IVC) by transjugular path under ultrasound guidance. Fluency covered stent was deployed to create the extrahepatic portacaval shunt after puncturing the target catheter from the IVC under the X-ray guidance, then shunt venography was performed. Enhanced CT of the abdomen helped identify and quantify the patency of the shunt and the presence of hemoperitoneum. Results The extrahepatic portacaval shunts were created successfully by only 1 puncture in 6 pigs. No extravasation was observed in shunt venography. One pig died of anesthesia on the day of operation. The extrahepatic portacaval shunts were failed in 2 pigs 3 days after the operation (one was occluded and the other one was narrowed by 80%). The extrahepatic portacaval shunts were occluded 2 weeks after the operation in the remaining 3 pigs. The shunts were out of the liver and no hemoperitoneum was identified at necropsy in the 6 pigs. Conclusion TEPS is technically safe and feasible under the X-ray guidance.
