Özet

In this study, we aimed to evaluate the vascular structures of the lower limb with multidetector computed tomography (CT) angiography and to reveal the importance of this method in preoperative planning of microsurgical transplantation. In 24 patients, lower-limb arteries were bilaterally evaluated with 16-detector spiral CT scanner in terms of patency, stenosis, or occlusion; maximal and minimal external diameters through their traces; and variations as well as length of the peroneal artery. The peroneal artery was absent unilaterally in two patients (4.3%). The mean maximal and minimal diameters were as 2.77 and 1.63, 2.92 and 1.75, and 2.72 and 1.50 mm for anterior and posterior tibial and peroneal arteries, respectively. The ranges of lengths of peroneal arteries were 50 to 117 mm. This valuable tool can provide detailed information about vascular and the remaining anatomic structures by means of its high-resolution characteristics before planning free flap surgery.
