The number of patent tibial vessels does not influence primary patency after nitinol stenting of the femoral and popliteal arteries

Abstract

The number of patent tibial vessels does not influence the primary patency of primarily stented femoral and popliteal arteries. TASC II classification appears to be significantly more predictive of initial failure after angioplasty and stenting of these vessels.

Impact of Tibial Runoff on Outcomes of Endovascular Treatment for Femoropopliteal Atherosclerotic Lesions

“…Especially, in the endovascular treatment of the femoropopliteal artery, BTK arteries act as an outflow runoff vessel, and it can affect the outcomes of femoropopliteal intervention itself. 1 -4,6,7,9,13 In addition, the existence of BTK lesions can also reflect a high burden of atherosclerosis and be associated with specific cardiovascular comorbidities and risks. Here, we focused on the clinical implication of poor tibial runoff caused by the existence of BTK lesions on femoropopliteal intervention.…”

“…14 -16 The effect of poor distal runoff and the clinical efficacy of concomitant tibial intervention after superficial femoral artery intervention was reported. 1 -4 Black et al reported that insulin-dependent diabetes mellitus, poor runoff into the foot, and renal insufficiency were associated with treatment failure after infrainguinal endoluminal intervention. 17 Davies showed that patency, freedom from recurrent symptoms, and limb salvage were affected by poor runoff vessels after superficial femoral artery endoluminal intervention in patients with critical limb ischemia.…”

“…7,13 However, the efficacy and indication of BTK intervention combined with femoropopliteal intervention are still unclear. 3 -6 In addition, several reports on BTK interventions only focus on patients with critical limb ischemia. 4,7,13 In the study of Smolock et al, despite the improved patency and freedom from target vessel revascularization, there was no significant outcome after concomitant tibial intervention in terms of limb salvage, amputation-free survival, freedom from recurrent symptoms, and clinical success after superficial femoral artery intervention.…”

“…However, the implications of tibial runoff on femoropopliteal endoluminal interventions in patients with claudication and critical limb ischemia are unclear in terms of outcome end points. 1 -4 In addition, the indication for tibial intervention as a concomitant procedure in combination with femoropopliteal intervention and its beneficial clinical outcomes are not well known. 3 -6 The aim of this study is to investigate the impact of tibial runoff on outcomes of femoropopliteal interventions.…”

The Factors Affecting Recurrence of Symptoms after Infrainguinal Arterial Endovascular Angioplasty

“…Several studies have shown that the number of runoff vessels improves outcomes in patients with infra-inguinal arterial occlusive disease undergoing endovascular angioplasty [ 2 , 8 , 9 ]. In contrast, another study has reported that the number of tibial vessels did not significantly influence the outcomes of 289 limbs in 236 patients with primary endovascular stenting of the femoral and popliteal arteries, as determined at seven years after surgery [ 10 ]. In this study, the number of distal runoff vessels likewise did not have a statistically significant effect.…”
