BACKGROUND: Bypass grafting for repeat operation or complex forms of descending aortic disease is an alternative approach to decrease potential complications of anatomic repair. METHODS: Between December 1985 and February 1998, 17 patients (13 men, 4 women; mean age, 47.6 +/- 18.5 years) underwent ascending aorta-to-descending aorta bypass through a median sternotomy and posterior pericardial approach. Indications for operation were coarctation or recoarctation of aorta in 8 patients, Takayasu's aortitis in 2, prosthetic aortic valve stenosis associated with coarctation of aorta, complex descending aortic arch aneurysm, reoperation for chronic descending aortic dissection, long-segment stenosis of descending aorta, acquired coarctation after repair of traumatic transection of descending aorta, severe aortic atherosclerosis, and false aneurysm of descending aorta after repair of coarctation in 1 patient each. Concomitant procedures were performed in 12 patients. RESULTS: No early or late mortality has occurred. Follow-up was 100% complete and extended to 12 years (mean, 2.7 +/- 3.3 years). No late graft-related complications have occurred; 1 patient had successful repair of perivalvular leak after mitral valve replacement, and 1 patient had replacement of lower descending and abdominal aorta. CONCLUSIONS: Exposure of the descending aorta through the posterior pericardium for ascending aorta-descending aorta bypass is a safe alternative and particularly useful when simultaneous intracardiac repair is necessary. 相似文献

We describe two adult patients who underwent extraanatomic ascending aorta-to-descending thoracic aorta bypass grafting for repair of aortic coarctation through a median sternotomy and posterior pericardial approach. Of the two patients, one presented with coarctation and concurrent cardiovascular disorders, and the other, with residual coarctation. Cardiopulmonary bypass was established with double arterial cannulation in the aorta or axillary artery and the femoral artery ensure adequate perfusion proximal and distal to coarctation and bicaval cannulation. The heart was retracted cephalic and superiorly, and the descending thoracic aorta was exposed through the posterior pericardium. After achieving distal anastomosis, the graft was directed anterior to the inferior vena cava and lateral to the right atrium, and anastomosed to the right lateral aspect of the ascending aorta. A 14-mm graft was used. In one patient receiving concomitant procedures, mitral valve repair and replacement of the ascending aorta was performed after the distal anastomosis. 相似文献

Coarctation of the aorta is a common congenital defect that may be undiagnosed until adulthood. Moreover, coarctation is associated with congenital and acquired cardiac pathology that may require surgical intervention. The management of an adult patient with aortic coarctation and an associated cardiac defect poses a great technical challenge since there are no standard guidelines for the therapy of such a complex pathology. Several extra-anatomic bypass grafting techniques have been described, including methods in which distal anastomosis is performed on the descending thoracic aorta, allowing simultaneous intracardiac repair. We report here a 37-year old man who was diagnosed with an aortic root aneurysm and aortic coarctation. The patient was treated electively with a single-stage approach through a median sternotomy that consisted of valve-sparing replacement of the aortic root and ascending-to-descending extra-anatomic aortic bypass, using a 18-mm Dacron graft. Firstly, the aortic root was replaced with the Yacoub remodelling procedure, and then the distal anastomosis was performed to the descending aorta, behind the heart, with the posterior pericardial approach. The extra-anatomic bypass graft was brought laterally from the right atrium and implanted in the ascending graft. Postoperative recovery was uneventful and a control computed tomographic angiogram 1 month after complete repair showed good results. 相似文献

Two varied cases of coarctation of the aorta are described, in which transpericardial ascending to descending thoracic aortic conduits were routed around the right atrium, utilizing deep hypothermic circulatory arrest. The approach was through a median sternotomy in two patients. The first case is a 52-year-old female who underwent combined aortic valve replacement for aortic stenosis and repair of aortic coarctation distal to the left subclavian artery. The second case was a fifth time reoperation in a 12-year-old girl with recurrent coarctating. Both patients remain well and asymptomatic. 相似文献

The right aortic arch with coarctation of the aorta was reported. A 56-year-old woman admitted to the hospital because of headache and hypertension. Cardiac catheterization revealed the right aortic arch with coarctation of the aorta and 80 mmHg pressure gradient across the coarctation. The bypass operation with a 14 mm Dacron graft between the ascending to descending aorta was performed. There was no peak systolic pressure gradient between the ascending and descending aorta after bypass operation. This patient is the fourth case report with both mirror-image type right aortic arch and coarctation of the aorta. 相似文献

Twenty-three patients aged 5 to 53 years with recurrent or complex coarctations of the aorta were successfully operated upon using bypass grafts. This technique of repair was selected for 5 patients with recurrent coarctation, 11 with long-segment coarctation with or without hypoplasia of the transverse aortic arch, and 7 with inadequate collateral circulation. Nineteen patients had bypass grafts from the left subclavian artery to the distal descending thoracic aorta. The other 4 had a combined approach through a left thoractomy and median sternotomy with grafts between the ascending and descending thoracic aorta. All patients survived the operative procedure. One patient were reexplored for a hemothorax and 5 developed transient postoperative hypertension. There were no instances of abdominal vasculitis or lower extremity paralysis. These patients have been followed from 3 months to 11 years postoperatively, and all but 1 are alive and well. Twenty-two are normotensive, and none have the sequelae of hypertensive disease. Gradients up to only 15 mm Hg exist between upper and lower extremity blood pressures. Five patients have undergone postoperative catheterization and aortography, and all have patent grafts. This procedure is a useful and adjunct in difficult coarctations of the aorta and can be safely performed with excellent reproducible long-term results. 相似文献

An interrupted aortic arch accompanied by further surgically reparable cardiac lesions is a rare combination in adult patients. We describe treatment of an interrupted aortic arch, coronary artery bypass grafting (CABG), and aortic valve replacement (AVR) performed simultaneously through median sternotomy in a 64-year-old man. The patient underwent surgery performed using standard cardiopulmonary bypass with cannulation of the ascending aorta and the right atrium, hypothermia (24.6degreesC), and blood cardioplegic arrest. Four aortocoronary vein grafts and pericardial aortic valve replacement were carried out. Finally, the posterior pericardium was opened, and a 16-mm prosthesis was anastomosed to the descending aorta during side clamping using a 4-0 monofilament continuous suture. Optimal placement of the prosthesis was obtained by guiding it to the ascending aorta laterally to the right atrium and passing it between the inferior vena cava and right inferior lung vein. The operation was carried out without complications, and the postoperative course was uneventful. Magnetic resonance imaging showed competent aortic valve prosthesis and highly decreased collateral flow via the internal mammary arteries. Postoperatively both inguinal pulses were present, and the patient was free of angina. In the presence of an interrupted aortic arch, extraanatomical bypass via the posterior pericardium between the ascending and descending aorta can safely be performed at the same time as CABG and AVR through a median sternotomy. 相似文献

Surgical Management of Coarctation of the Aorta in Adults with Concurrent Cardiac and Aortic Disease
Roosevelt Bryant III M.D. Gonzalo Gonzalez‐Stawinski M.D. Gosta B. Pettersson M.D. Ph.D. Lars G. Svensson M.D. Ph.D. 《Journal of cardiac surgery》2008,23(6):787-790
Abstract We evaluated our experience with the surgical management of aortic coarctation (ACo) in adults with concurrent cardiac and aortic disease approached via median sternotomy. Eight patients were presented using a variety of repair techniques including end‐to‐end anastomosis, transpericardial ascending aorta to descending aorta bypass, and stage 1 elephant trunk insertion. All patients were male and symptomatic at presentation. The average age was 41 years (range, 27–67 years). The systolic blood pressure decreased by a mean of 49 mmHg in the patients presenting with hypertension. The postoperative New York Heart Association functional class was I or II in all patients. Mean length of stay was 7.7 days. There were no perioperative complications, and overall survival was 100%. Operative repair of complex ACo can be safely accomplished through the mediastinum in patients in whom a conventional left thoracotomy may not be the preferred approach. 相似文献

BACKGROUND AND AIM: Conventional mitral valve replacement (MVR) is carried out under cardioplegic arrest with cross-clamping of the ascending aorta during cardiopulmonary bypass. In this case, MVR was performed with on-pump beating heart technique without cross-clamping the aorta because of the diffuse adhesion around the ascending aorta, and tube graft presence between ascending and descending aortas. METHODS: A 47-year-old female patient had aorto-aortic bypass graft from ascending aorta to descending aorta with median sternotomy and left thoracotomy in single stage because of aortic coarctation 2 years ago in our cardiac center. She was admitted to the hospital with palpitation and dyspnea on mild exertion. Transthoracic echocardiography revealed 4th degree mitral insufficiency. RESULTS: MVR was carried out through remedian sternotomy with on-pump beating heart technique without cross-clamping the aorta. CONCLUSIONS: MVR with on-pump beating heart technique offers a safe approach when excessive dissection is required to place cross-clamp on the ascending aorta. 相似文献
