Abstract
The clinical manifestation of atherosclerosis involving the abdominal aorta and iliac arteries is one of the most common therapeutic challenges encountered by vascular surgeons.
Endovascular treatment for iliac artery occlusive disease can be considered as an alternative to open surgery even for TASC-II C/D disease. Therefore, iliac artery angioplasty should be recommended as a first choice therapy for aorto-iliac occlusive disease as it is a minimally invasive in comparison to open surgery.
Although aorto-bifemoral bypass appears to have better long-term patency than the currently available endovascular strategies for diffuse aorto-iliac occlusive disease, the risks of surgery are significantly greater than the risks of an endovascular approach, in terms of not only mortality but also major morbidity and delay in return to normal activities.
In conclusion in this study, endovascular procedures done for TASC C& D were successful as shown in this study which includes 40 patients 65% TASC C and 35% TASC D. all of the patients were symptomatic and included in this study in the form of rest pain 77.5% and gangrene 75%.
The results were as following: TASC C show good blood flow with restoration of blood stream in 92.31 % of cases and failure of 7.69 % of cases. According to TASC D show good blood flow with restoration of blood stream in 85.71 % of cases and failure of 14.29%. TASC C immediate and late clinical assessment were the same: improvement 92.31%, no improvement in 7.69%. While TASC D immediate and late clinical assessment were the same: improvement 85.71%, no improvement in 14.29%.
This means that endovascular intervention in both TASC C & D give satisfactory results especially in TASC C, this indicates endovascular procedures will be the first choice in management of iliac occlusions of all types in steed of surgery first.
Certainly, the potential advantages of percutaneous therapy as compared to surgical reconstruction are significant: No general anesthesia or lengthy incisions, shorter hospitalization, lower morbidity and mortality, earlier intervention in the course of the disease and less complicated reapplication in the event of disease recurrence.
