Stenting of Iliac Artery through Brachial Approach.

In some cases the iliac artery occlusive disease cannot be approached through standard access. The preferred access sites are the ipsilateral retrograde femoral and the contralateral antegrade cross-over, although occasionally these approaches do not allow an effective engagement of the lesion, especially when there is a total occlusion or complex aortoiliac lesion. We are reporting a case of iliac artery stenting through brachial approach.This technique is safe and effective. It provides enough support for stiff balloon or stent catheter to be advanced through this long sheath.

A Case Report of Middle Aortic Syndrome: A Rare Vascular Disorder.

The middle aortic syndrome (MAS) is rare (about 0.5-2% of all the cases of aortic coarctation) vascular disorder characterized by severe narrowing in the descending thoracic aorta, abdominal aorta, or both. It can be congenital or acquired due to several conditions.MAS may present clinically as uncontrolled hypertension, abdominal angina or lower limb claudication. Surgical treatment is effective in controlling symptom and improves life expectancy.

Aorto-bi-Femoral Bypass for Aorto-Iliac Occlusive Disease: Recent Experience at the National Institute of Cardiovascular Diseases (NICVD).

Background & Objectives: Aorto-bi-femoral bypass is one of the most important surgical strategies in vascular surgical practice. The procedure is employed in surgical revascularization for both stenotic and aneurysmal diseases involving the aorto-iliac segment. The present study was carried out to analyze our recent experiences with this procedure for aorto-iliac occlusive diseases (AIOD) at the National Institute of Cardiovascular Diseases (NICVD). Materials and Methods: Over a period of 3 years (April 2008 to March 2011), a total of 47 patients underwent aorto-bi-femoral or aorto-bisiliac bypass grafting for AIOD using a Y-graft prosthesis. The mean age of the patients was 46.4 years (range 25-75 years). Thirty eight of the patients were male and the remaining 9 were female. A retroperitoneal approach was used in 27 patients. In the remaining 20 patients, the operation was done using a transperitoneal approach. A Gelatin-coated Dacron Y-graft prosthesis was used in 43 (5 of which were silver-coated prosthesis) patients while PTFE (Polytetrafluoroethylene) prosthesis was used in the remaining 4 patients. The operation was carried out under epidural anesthesia with sedation in most cases. Results: The operation was well-tolerated in all patients. There was no intraoperative mortality in this series. Two patients died in the immediate post-operative period- one due to myocardial infarction and the other due to acute renal shut-down leading to renal failure accounting for a mortality rate of 4.3%. Wound infection and lymphorrhoea at the groin incision site were the two main immediate post-operative complications. There was no incidence of graft infection in this series. Twelve patients were available for post-operative follow-up up to 2 years. Out of them, 5 patients returned with occluded grafts 8-23 months after the operation. Three of these patients underwent graft excision with re-do Y-graft bypass. The remaining two were treated with extra-anatomic bypass (Axillobifemoral). Conclusions: Aorto-bi-femoral bypass is an effective surgical strategy for occlusive diseases involving the abdominal aorta and the iliac arteries. The procedure is well-tolerated with a low incidence of early post-procedural complications and graft failure. However, poor adherence of the patients to follow-up remains a significant obstacle for evaluating the long-term outcome of this procedure.
