Native chronic total occlusion recanalization after lower limb bypass graft occlusion: A series of nine cases

Abstract

In this preliminary study, endovascular recanalization of native CTO showed satisfactory outcomes in patients with bypass graft occlusion.

Recanalization of native superficial femoral artery chronic total occlusion after failed femoropopliteal bypass in patients with critical limb ischemia

“…The results of these studies were similar to ours. The technical success rates were ranging from 89% to 100% and limb salvage rates were 81‐94% and 65‐96% at 1‐ and 2‐years of follow‐up . One‐year primary and secondary patency rates in those studies ranged from 16% to 60% and from 44% to 96%, respectively .…”

Predictors of adverse clinical outcomes after successful infrapopliteal intervention

“…A tapered tip coronary guide wire or 0.010‐inch guide wire was used in a case of failed 0.014‐inch guide wire crossing (two cases, 1.9%). For recanalization of chronic total occlusion (CTO) lesions in crural segments, a conventional coronary technique or a “J‐loop technique” using a 0.014‐inch guide wire was used to cross the occlusive lesion [4–7]. When a penetration technique was needed, a CTO‐dedicated 0.014‐ and/or 0.018‐inch guide wire were used.…”

“…With the projected increase in patients with diabetes and renal failure, infrapopliteal artery disease is a mainstay of critical limb ischemia (CLI), whether single‐segment or multisegment disease [1, 2]. During the last decade, infrapopliteal balloon angioplasty has gained significant popularity with the application of stents [3–8]. More recently, even below‐the‐ankle lesions have entered the domain of catheter‐based revascularization [7, 9].…”

Subintimal Angioplasty of Lengthy Femorotibial Total Occlusion in Buerger's Disease

“…The subintimal angioplasty technique has become quite popular for the treatment of atherosclerotic CTOs in the lower limb. [8][9][10][11][12][13] As shown in this case, subintimal angioplasty with a 0.014-inch guidewire was able to safely and rapidly traverse the entire occlusive lesion extending over the knee joint in the setting of nonatherosclerotic Buerger's disease, although the management of coexistent guidewire-induced vasospasm and underlying thrombus might be required.…”
