Factors influencing the necessity for preoperative vascular imaging before harvesting a vascularized fibular flap

Abstract

This study was carried out to identify groups of patients who would benefit from this angiography. The angiographic images of a random group of patients were studied; the correlations between the vascular state of the lower extremities and vessel pathology were investigated; and the possible links of these findings with certain medical conditions were explored. Three experienced observers independently evaluated the angiograms of 185 patients. The status of all 3 vessels of the lower extremities (anterior tibial artery, posterior tibial artery, and peroneal artery) was evaluated. The patients' gender, age, drinking and smoking habits, and medical conditions were documented. We found a significant correlation between pathology of the arteries of the lower extremity and blood cholesterol level, blood pressure, coronary heart disease, diabetes mellitus, and age. We suggest that preoperative vascular imaging be carried out in patients with comorbidities to reduce the potential for flap failure and to minimize donor site complications.
