Abstract: Though the use of the radial artery (RA) as a coronary artery bypass graft has been accepted world widely in myocardial revascularization, there has been no uniformity regarding harvest techniques, assessment of the adequacy of hand collateral circulation, antispasm rotocols, selection of target vessels, and the site of proximal anastomosis. It is widely believed and practiced that the RA should be harvested as a pedicle graft and preferably be used to bypass critically stenosed (gt;70% stenosis) coronary arteries. It is used either as a free graft with proximal anastomosis to the ascending aorta or as a composite arterial graft along with the left or right internal thoracic artery. The patency of RA grafts depends on the severity of the target coronary artery stenosis and target artery location rather than its use as an aortocoronary conduit or composite graft. Though lacking of evidences, most surgeons use antispasm therapy for RA conduits. There are advantages in using RA as an alternative for right internal mammary artery in total artery coronary revascularization.
Objective To investigate the gastrointestinal(GI) protective effect of Omeprazole on children undergoing thoracoscopic heart surgery with cardiopulmonary bypass (CPB). Methods One hundred and twenty seven patients who were scheduled for cardiac surgery with CPB were randomly equally divided into three groups. Group A and B underwent thoracoscopic heart surgery, while the control group underwent conventional heart surgery by sternotomy. Before CPB, group A was treated with Omeprazole 10mg added to the priming solution.? Group B and the control group were treated by adding the same amount of normal saline (to the priming solution). pH and red blood cell count of gastric secretion and serum gastric level (Assay Designs ELISA) were measured at the following intervals: before CPB, 30 minutes into CPB, at termination of CPB,4 and 24 hours after termination of CPB. Results Compare to prior to CBP, the value of the gastric pH in group A was significantly higher (Plt;0.01), and that of group B was significantly lower (Plt;0.05)at the end of CPB. The same value in the control group was significantly lower (Plt;0.05)4h, after the end of CPB. Compared to prior CPB, the mean red blood cell count of gastric secretion and serum gastric level were significantly descent (Plt;0.01) in all there group post CBP. Compare to the control group, the mean gastric pH level in group A was significantly elevated at all time intervals post CBP; while the mean gastric secretin red blood cell count was significantly decreased. The mean serum level in group A 30 min post CBP was significantly lower than that in group B and the control group. Compared to the control group, the mean gastric pH level was significantly lower in group B but returned to the pre-CPB level in 24 h. The mean gastric secretin red blood cell amount and serums gastric level in group B at all time intervals were significantly decreased compare to those of the control group. Conclusion Thoracoscopic heart surgery of children with CPB
Objective To evaluate surgical treatment of infected femoral artery pseudoaneurysm. Methods The data on surgical treatment of 45 patients with infected femoral artery pseudoaneurysm admitted from January 2003 to June 2008 were analyzed retrospectively. Fourty-three patients underwent operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis. Two patients were unavoidable to undergo removing of infected femoral artery pseudoaneurysm and ligating the proximal and distal artery of pseudoaneurysm because of severe infection and large volume. Results The patients were followed up from 3 to 12 months (mean 7.82 months). The limbs of all the patients underwent bypass graft with vascular prosthesis were salvaged successfully, patients of which had secondary wound healing and had not intermittent lameness. One of two patients performed ligation of artery was salvaged successfully but had severe intermittent lameness, another patient underwent high amputation above knee because of ischemic gangrene. Conclusion For infected femoral artery pseudoaneurysm, the operative treatment including excision of infected femoral artery pseudoaneurysm, exhaustive debridement and bypass graft with vascular prosthesis is effective and safe.
Objective To explore of a surgical approach of posterior pericardial ascending-to-descending aortic bypass through a median sternotomy for complex coarctation and interrupted aortic arch adult patients with coexistent cardiac disorder. Methods We retrospectively reviewed the clinical data of 2 adult patients with complex coarctation and 1 adult patient with interrupted aortic arch and all with coexistent cardiac disorder who underwent ascending-to-descending aortic bypass in our hospital between April 2010 and January 2015. There were 2 males and 1 female with age of 35.6 (27-46) years. One patient was with complex coarctation, and prolapse of anterior mitral leaflet with moderate regurgitation. One patient was with complex coarctation, and bicuspid aortic valve with severe aortic regurgitation, and ascending aortic aneurysm. One patient was with interrupted aortic arch (type A), and bicuspid aortic valve with mild stenosis, and secundum atrial septal defect. The surgical approach used in all patients was the median sternotomy. After aorta, femoral artery and bicaval cannulation, hypothermic cardiopulmonary bypass was established. With posterior pericardial ascending-to-descending aortic bypass procedure for repair of complex coarctation and interrupted aortic arch with coexistent cardiac disorder. Results There was no death. The symptoms of the patients obviously improved. All the patients were alive with ascending-to-descending aortic bypass procedure at a mean follow-up ranged from 2 to 59 months. Except that one patient had residual upper-extremity hypertension, and needed antihypertensive medications taken postoperatively, other patients’ systolic blood pressure returned to normal level. All patients’ lower-extremity fatigability resolved. Postoperative computed tomography angiography (CTA) of the patients showed that dacron graft was unobstructed with no graft-related complications of kinking and narrowing, development of false aneurysms or other complications. Conclusion The surgical management of adult patients’ complex coarctation and interrupted aortic arch with coexistent cardiac disorder, a one-stage approach using pericardial ascending-to-descending aortic bypass through a median sternotomy is an alternative surgery.
