Computed tomographic angiography showed severe aortic stenosis caused by calcifications protruding into the aortic lumen proximal and distal to the visceral and renal branches, so-called coral reef aorta. An axillo-iliac bypass was performed. Postoperatively, the patient developed ileus and acute renal failure, presumably caused by a steal phenomenon to the lower extremities. Endovascular stenting of the aorta increased forward blood flow and dramatically improved the patient’s condition. This case study illustrates potential hemodynamic complications after extra-anatomical axillo-iliac bypass for coral reef aorta.展开更多

We summarize our experiences of extra-anatomic bypass from ascending aorta for atypical aortic coarctation. Methods Between January 2005 and February 2008, 5 women aged from 18 to 64 years underwent extra-anatomic bypass from ascending aorta to abdominal aorta or iliac artery bypass for treatment of atypical aortic coarctation. Preoperatively, all patients had hypertension and needed antihypertensive medications. Systolic blood pressure was 151 ± 9 mmHg. Ankle pressure index (API) 0.23 in left and 0.56± 0.23 in right. Average systolic pressure gradient of aortic stenosis was 76 were 0.60 ± 18 mmHg. Three patients underwent concomitant cardiac operation, including coronary artery bypass grafting, Benta11 procedure and atrial septal defect repair. Results There was no hospital and late mortality during 58 + 15 months follow-up (range from 44 to 81 months). Postoperative systolic blood pressure was reduced to 126 ± 11 mmHg at the time of discharge. All patients maintained normal blood pressure without medication during follow-up. API was improved to 1.12 ± 0.24 in left and 1.17 ± 0.25 in right (compared with preoperative data, P 〈0.05). Follow-up computer tomography showed patency in all grafts. Conclusions Surgical treatment of atypical aortic coarctation with extra-anatomic bypass originating from ascending aorta alleviates hypertension and low limb ischemia.

He underwent simultaneously in singlestage a Bentall’s procedure and an extra-anatomic ascending-descending aortic bypass grafting by 14-mm Dacron tube, through median sternotomy. The immediate postoperative outcome was favourable. The CT scan control for 7 years after surgery showed a good patency of the extra-anatomic bypass.展开更多
