Purpose: To illustrate the utility of color flow duplex ultrasound (CFDU) in the diagnosis and stent-graft treatment of a rare arteriovenous fistula (AVF) involving the vertebral artery and vein. Case Report: An iatrogenic AVF involving the right vertebral artery and vein was diagnosed in a 45-year-old man using CFDU. Treatment was recommended due to the large volume of blood shunted through the fistula and the associated loud bruit. Endoluminal treatment involved deployment of a covered stent within the vertebral artery to exclude the fistula. Postoperative CFDU confirmed the success of the treatment. Conclusions: CFDU can be utilized to accurately diagnose unusual lesions, such as AVFs involving the vertebral artery. The technique is also useful in planning treatment and monitoring the durability of stent-grafts implanted to obliterate this type of defect.

Purpose: To report the results of a multicenter feasibility study of the Jostent balloon-expandable stent-graft in the treatment of renal and iliac artery lesions. Methods: Twenty-three patients (17 men; mean age 62 years, range 38–80) with lesions in the renal (n = 12) or iliac arteries (n = 12) were enrolled in 6 centers over a 1-year period. Preprocedural computed tomography (CT) and angiography were performed in all patients. The Jostent device was implanted in the 24 arteries to treat 11 in-stent stenoses, 2 arterial ruptures, 2 aneurysms, 2 dissections, 2 ulcerated stenoses, and 5 chronic occlusions. Follow-up included color duplex ultrasound examination on the day after the procedure and at 6 months; patients with renal artery stent-grafts were also evaluated with CT angiography. Results: Twenty-seven stent-grafts were deployed successfully in the 24 (100%) arteries. Seven (30%) patients required adjunctive procedures to address 1 acute in-stent thrombosis, 2 dissections, and 4 in-stent residual stenoses. At 6-month follow-up, 2 (8.3%) restenoses occurred in the renal arteries; these were treated successfully using balloon angioplasty. Conclusions: These data suggest that a balloon-expandable stent-graft may be safe and useful in patients with selected peripheral indications.

Effective Treatment Option

Background —Iliac artery aneurysms have traditionally been treated by direct surgical reconstruction. Endovascular stent grafts have been developed to provide an effective but less invasive treatment option for patients with peripheral arterial aneurysms. Methods and Results —In 48 patients, a total of 53 endoprostheses (mean length 7.3 cm, mean diameter 8.1 mm) were implanted into the iliac arteries (common iliac artery n=29, external iliac artery n=19) for percutaneous exclusion of aneurysmal lesions. The technical success of complete exclusion of the aneurysm was achieved in 47 of 48 cases (97.9%). In 1 case, persistent perfusion through a collateral branch was detected; however, this aneurysm thrombosed spontaneously within 2 weeks. In all patients, graft patency was monitored by clinical examination, which included the standardized treadmill test with calculation of the ankle-brachial Doppler index and color-coded duplex ultrasound. Forty-two of the 48 patients (87.5%) underwent follow-up angiography. According to Kaplan-Meier life-table calculations, primary patency rates were 100% after 1 year, 97.9% after 2 years, 94.9% after 3 years, and 87.6% after 4 years. Serial contrast-enhanced spiral CT scans were performed to rule out late procedural failures and to assess growth progression of the lesions. No secondary leaks were observed. Furthermore, the aneurysm diameter had reduced from 24.8±8.0 mm to 23.1±6.6 mm at the last follow-up ( P =NS). Conclusions —Stent grafts are a safe and effective treatment option for iliac artery aneurysms and provide good long-term patency of the graft.

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.

Vein Bypass

Abstract. Background: Surgical revascularization for chronic critical limb ischaemia in patients with thromboangiitis obliterans (TAO) still remains controversial. Generally, besides cessation of smoking, conservative treatment supported by intravenous administration of vasoactive agents is regarded as the treatment of choice, in combination with local wound therapy or minor amputation. Patients and methods: In four male patients (42-47 years) surgical revascularization was chosen as therapy for established gangrene or non-healing ulceration after unsuccessful conservative treatment and cessation of smoking. Angiography was able to identify a suitable distal arterial segment for the bypass which was revascularized by means of an autologous vein graft. Grafts were followed with repetitive duplex ultrasound. Revision of the bypass graft was initiated if indicated by pathological duplex findings. Results: In all cases a bypass could be constructed with either the ipsilateral greater saphenous vein or arm veins. A distal origin configuration was possible in three cases with popliteo-pedal or cruro-pedal bypasses. In the fourth case the distal superficial femoral artery was used for inflow. Two early graft thromboses underwent successful revision. During follow-up, duplex ultrasound identified graft stenoses in three bypasses which were successfully treated with endovascular techniques. All grafts are patent with complete resolution of ischaemic symptoms after 46, 42, 32, and 29 months. The patients remained non-smokers and returned to a professional life. Conclusions: Surgical therapy with distal vein bypass for persistent ischaemic symptoms after definitive cessation of smoking seems feasible in selected cases with TAO and a suitable distal artery. Close follow-ups of the patients with duplex ultrasound are necessary to identify developing vein graft stenoses. Angioplasty seems to be an important part of the long-term therapeutic concept.
