Seventy-four cases of peripheral arterial injuries in recent 30 years were reported. Mostof them were main arteies in extremeties. Twenty-eight cases were performed end to end anastomosis and 7 of them received amputation for various complications. We also performed 12 cases of reparatidn of wall, 20 cases of vascular grafts and 7 cases of arterial ligation. There were 16 cases of amputation and one death. We think that artemal injuries should be operated as soon as possible. Arteial reconstruction was mostly used, including reparation of wall, end-to-end anastomosis and autovenous graft. Other procedures should be emphasized, such as complete debridement of the soft tissue and vessels, appropriate fixation of fracture, exploration and reconstruction of major veins, enough decompression of interfascia compartment, proper drainage of would and good surgical skill. Local and general anticoagulation were good to treatment of arterial injuries during and after operation .
Objective To explore improvement of orthotopic liver transplantation model in rhesus monkey. Methods Healthy rhesus monkeys were chosen to perform orthotopic liver transplantation for 10 cases. The model was established by drawing on a variety of animal model methods, and the portal vein cuff method was used to establish stable model of orthotopic liver transplantation in rhesus monkeys. Results Ten orthotopic liver transplantation models in rhesus were performed, and the achievement ratio of operation was 10/10. The time of donor hepatectomy and donor preparation was (20±5) min and (30±7) min, respectively. The operation time of recipient and anhepatic phase were (180±35) min and (17±4) min, respectively. After 24 h of operation 9 cases survived, one case died of intra-abdominal hemorrhage after 9 h of operation. After 72 h of operation 8 cases survived, and one case died of upper gastrointestinal bleeding after 38 h of operation. After one week of operation 5 cases survived, and 3 cases died of rejection after 9, 11, and 11 d of operation, respectively. The longest survival time was 32 d, but all of them also died of rejection. No portal vein thrombosis and biliary complications were found in all recipients.Conclusion The improved rhesus monkey model of orthotopic liver transplantation is easy to perform with high achievement ratio of operation. It is an ideal animal model for pre-clinical studies of liver transplantation.
Objective To review various kinds of therapeutic methods for restenosis after reconstructive vascular operation. Methods The literatures about prevention and treatment for restenosis after reconstructive vascular operation were reviewed. Results Therapeutic methods for vascular restenosis include gene therapy, drug treatment, placing external stent around the vein graft and physical therapy. The methods of gene therapy include transferring genes that inhibit the proliferation of vascular smooth muscle cell (VSMC) and inactivating genes that promote the proliferation of VSMC through technology of antisensenucleic acids or RNA interference. Conclusion Current treatment for restenosis after reconstructive varscular operation have both advantages and disadvantages, some of which are still being disputed. With the development of the technology of molecular biology, gene therapy would be the most effective therapy method for vascular restenosis.
ObjectiveTo explore the clinical significance of hepatectomy combined with vascular reconstruction in hilar cholangiocarcinoma with vascular invasion. MethodsThe clinical data of 62 cases of hilar cholangiocarcinoma with vascular invasion in Suqian People's Hospital of Nanjing Drum-Tower Hospital Group from January 2006 to January 2014 were analyzed retrospectively. All cases were divided into two groups according to assessment of surgical trauma tolerance, nutritional status, and family's wishes. Thirty-three cases underwent hilar cholangiocarcinoma radical operation and hepatic artery combined with portal vein resection and reconstruction (combined resection group), while 29 cases of hilar cholangiocarcinoma underwent palliative surgery for treating jaundice in synchronization (palliative operation group). ResultsThe median survivals in combined resection group and palliative operation group was 26.3 and 9.6 months, respectively. The survival rates of 1-year, 2-year, and 3-year between combined resection group and palliative operation group were 84.85% vs. 26.32%, 66.67% vs. 15.79%, and 42.42% vs. 0, respectively, there were significant differences between both groups in survival time and survival rate (t=4.470, P=0.000; χ2=28.338, 20.348, and 15.891, P=0.000). Among of 33 cases in combined resection group, postoperative complications occurred in 9 cases, the rate of complications was 27.27% and the mortality rate in perioperative period was 3.03%; while postoperative complications in palliative operation group occurred in 5 cases, the rate of complications was 17.24%, no case died in the perioperative period. There were no significant difference between both groups in the rate of postoperative complications and the mortality rate in perioperative period (χ2=0.888, P=0.346; χ2=0.893, P=0.345). ConclusionsHepatectomy combined with vascular resection and reconstruction can significantly improve the radical resection (R0) rate of HCCA, and greatly increase the 1-year, 2-year, and 3-year survival rates of patients. Furthermore, complications can be controlled, and the mortality rate in perioperative period does not increase.
ObjectiveTo investigate the safety and effectiveness of vascular reconstruction in patients with symptomatic tortuosity common carotid artery (SCAT). MethodsA retrospective analysis was made on the clinical data of 12 cases of SCAT treated with vascular reconstruction between June 2010 and October 2013. There were 11 females and 1 male with the mean age of 54.8 years (range, 48-62 years). The unilateral common carotid artery was involved in all cases. Imaging examination showed C-shaped tortuosity of 4-8 cm in length (mean, 5.4 cm). The CT, brain CT, ultrasound examinations, or angiography was performed at 1, 3, 6, 9, and 12 months, and annually. ResultsThe surgery success rate was 100% with no perioperative death and serious complications. The mean operation time was 1.98 hours; the mean blood loss was 50 mL; and the mean clamping time was 14.9 minutes. The systolic pressure gradient across the lesion was significantly decreased from (39.58±9.54) mm Hg (1 mm Hg=0.133 kPa) at pre-operation to (5.50±2.39) mm Hg at immediate after operation (t=15.492, P=0.000). No recurrence or stenosis was found at 9 months to 3 years of follow-up. The systolic and diastolic pressures at last follow-up were significantly improved to (132.17±6.24) mm Hg and (82.67±6.51) mm Hg from (152.83±14.80) mm Hg and (94.17±11.30) mm Hg at pre-operation (t=5.751, P=0.000; t=4.976, P=0.000). ConclusionVascular reconstruction in SCAT is recommended for good short- and mid-term effectiveness and relatively low complication and mortality after operation. Moreover, the long-term results still need to be investigated.
