An 87-year-old male was admitted with intermittent claudication of the left calf. We performed lower extremity angiography, which revealed stenosis of the left popliteal artery. Intravascular ultrasound (IVUS) image correctly identified the cystic appearance of visualized extravascular hypodensity, causing extrinsic compression of the lumen. We diagnosed the condition as cystic adventitial degeneration (CAD) of the popliteal artery. We operated a resection of a cyst with the artery and replaced the autovein graft (saphenous vein). After surgery, the patient was free of symptoms. CAD is a rare disease; thus, our IVUS findings may provide unique diagnostic clues in patients with CAD.

Abstract Background There is no consensus on the optimal guidewire passage route for femoropopliteal (FP) chronic total occlusion (CTO). If intraplaque wiring can be performed, a stent-less strategy using a drug-coated balloon can be realized even with FP CTO, and there is a high possibility that good expansion can be obtained even when stent deployment is performed. AnteOwl WR (AnteOwl) is a novel intravascular ultrasound (IVUS) device useful for navigating the second guidewire into the intraplaque route under IVUS observation from the subintimal space. Here, we describe representative cases of FP CTO in which CTO-specific IVUS was extremely useful. Case presentation Case 1 involved a 79-year-old man with total occlusion of the left superficial femoral artery (SFA). We used a contralateral antegrade approach, but the guidewire was advanced into the subintimal space. We advanced AnteOwl into the CTO. By utilizing the asymmetric structure of the transducer and the IVUS wire, we were able to reflect the positional relationship among the IVUS transducer, IVUS wire, and target plaque onto the angiographic image. By aiming the wiring in that direction, we succeeded in traversing the center of the plaque and finally succeeded in obtaining good expansion using the drug-coated balloon. Case 2 involved a 76-year-old woman with total occlusion from the SFA to the popliteal artery. We used an ipsilateral antegrade approach. When AnteOwl was placed on the wire and advanced to the popliteal artery, the subintimal space in the middle of the SFA could be visualized. We employed an IVUS-guided parallel wiring technique and succeeded in passing through all intraplaque routes. Although the CTO was long, we could easily advance through the intraplaque route by reflecting the information obtained from AnteOwl in angiography. Conclusions AnteOwl is an effective IVUS for FP CTO and facilitates a complex IVUS-guided procedure.

Saphenous vein is the most widely used conduit for arterial bypass procedures and aneurysms of the vein graft are rare. We report a true aneurysm of a reversed femoropopliteal saphenous vein graft implanted nine years earlier. Duplex ultrasonography identified an aneurysm of the saphenous vein graft and arteriography confirmed this finding. A consideration for endovascular coiling of the aneurysm was entertained, but no proximal “neck” on the aneurysm was present. The patient, therefore, underwent an uneventful resection of the aneurysm with end-to-end anastomosis. Histopathologic examination of the aneurysm demonstrated atherosclerotic degeneration with endothelial disruption, medial necrosis, and fibrous proliferation. The cause of a saphenous vein graft aneurysm is rare and unknown. The management of vein graft aneurysms, however, should be subject to the same criteria that apply to other aneurysms because once vein graft dilation occurs, it is followed by a rapid increase in size, which may lead to possible rupture.
