Collateral Vessels

Background The superficial femoral artery (SFA) is the most common site of lower extremity atherosclerosis, and collateral vessels from the deep femoral artery (DFA) play an important compensatory role between the iliofemoral segment and the popliteal artery. We examined SFA occlusion and collateral vessel developments in patients with diabetes mellitus using computed tomography (CT) angiography. We also compared the collateral systems from the DFA and the descending branch of the lateral circumflex femoral artery (dbLCFA) in the case of SFA occlusion. Methods We retrospectively reviewed 1,316 sets of CT angiographic data collected from 673 patients with diabetes between 2008 and 2010. The degree of stenosis in each segment of the proximal and distal SFA and the number and size of collateral vessels originating from the DFA and dbLCFA were measured using established scoring systems. In cases where the SFA was occluded, the numbers of collateral vessels originating from the DFA and the dbLCFA vessel were compared. Results The mean occlusion rate of the SFA was 15.6%. We noted that collateral vessels from DFA and dbLCFA were the main circulatory route in cases of occlusions of the SFA. More collateral vessels developed from the DFA than from the dbLCFA. Overall, 0.6% of the patients had only collateral systems from the dbLCFA. Conclusion When planning to use anterolateral thigh free flaps in diabetic patients with suspected SFA total occlusion, thorough investigations of the peripheral vessels are essential.

Legal Consequences

We report two cases of femoral vein thrombosis after arterial PTA and subsequent pressure stasis. We discuss the legal consequences of these complications for information policies. Because venous thrombembolism following an arterial PTA might cause serious sequel or life threatening complications, there is a clear obligation for explicit information of the patients about this rare complication.

Good Treatment Option

We demonstrate feasibility of implantation of a self-expanding interwoven nitinol stent in a claudicant, where recanalization attempt of a heavily calcified, occluded superficial femoral artery (TASC D lesion) was complicated by a previously implanted, fractured standard stent. Wire passage through the occlusion and beyond the fractured stent could only be achieved through the subintimal space. A dedicated reentry device was used to allow distal wire entry into the true lumen at the level of the popliteal artery. Despite crushing of the fractured stent with a series of increasingly sized standard balloons, a significant recoil remainded in the area of the crushed stent. To secure patency of the femoro-popliteal artery we therefore decided to implant the novel self-expanding interwoven nitinol stent (Supera Veritas (TM), IDEV), whose unique feature is an exceptional high radial strength. Patient presented asymptomatic without any impairment of his walking capacity at three month follow up and duplex ultrasound confirmed patency of the stent. Subintimal recanalizations can be complicated by previously implanted stents, in particular in the presence of stent fracture, where intraluminal wire passage often can not be achieved. Considering the high radial strength and fracture resistance, interwoven nitinol stents represent a good treatment option in those challenging cases and they can be used to crush standard nitinol and ballonexpandable stents.
