Abstract
The aim of this study was to evaluate the early results of angiosome based endovascular foot revascularization in patients presented with critical lower limb ischaemia
The present study was conducted on twenty (20) limbs of (20) patients presented at the outpatient clinic (OPC) with critical lower limb ischaemia in the form of ischaemic ulcers & gangrene
Of The twenty patients included in this study there were 14 males and 6 females, Patients’ age at time of intervention ranged between 45 - 65 years, with a mean age of
56± 6 years.
The anatomical distribution of lower limb ischaemic lesions is as the following:
15 patients had toe gangrene, 2 patients had heel gangrene, 3 patients had ischaemic ulcer (2 on the dorsum of the foot & one on posterior aspect of the ankle.
Lesion Characteristics and Endovascular Procedures:
Among 20 limbs of 20 patients, all patients had tibio-peroneal lesions, 50% of them had superficial fermoral artery lesions.
Patients with superficial fermoral artery lesions had their lesions angioplastied.
10 patients had angioplasty of the artery that directly feeds the site of foot lesion (Group A) or direct group .We did 9 PTA angioplasty& one ATA angioplasty.
While the other 10 patients had angioplasty of the artery that do not directly feeds the site of foot lesion (Group B); We did 8 ATA angioplasty, one PTA angioplasty & ONE patient had peroneal artery angioplasty.
Immediately after revascularization, toe amputation was performed for cases with toe gangrene& cases with heel gangrene had debridement.
Follow up was at one week, one month and three months intervals. ABI was measured on every follow up visit, wound healing status was assessed (decrease in wound size, healthy granulation tissue).
After 3 months limb salvage rate in direct group was 100%, meanwhile it was 90% in the indirect group.
Healing of toe amputation stumps, ulcers was faster in direct group than indirect one, also healing was faster in non-diabetic patients. After 1st month of follow up, 9 cases from the direct group & one case from the indirect group had their wounds healed.
By follow up in 3rd month all cases from direct group, 7 cases of indirect group had their wounds healed& three cases from the indirect group shows non healing of their wounds& one of these three cases had transmetatarsal amputation then below knee amputation and a patient with heel gangrene had below knee amputation.
