We report the first successful application of nonferromagnetic embolization coils for endovascular exclusion of a mycotic right subclavian artery aneurysm. A 58‐year‐old woman presented with acute cervical pain and a pulsatile mass in the right supraclavicular fossa under antibiotic medication for subacute infectious endocarditis. Diagnostic work‐up including duplex sonography, digital subtraction angiography, and magnetic resonance imaging demonstrated a saccular aneurysm of the extrathoracic right subclavian artery. As an alternative to open surgery or stent‐graft repair, this pathology was electively treated by transcatheter coil embolization. No neurological deficit or ischemic symptoms were noted during 9 months clinical follow‐up. Multislice computed tomography scan revealed complete occlusion of the mycotic aneurysm 6 months after the interventional procedure. Transcatheter closure with Inconel embolization coils is a cost‐effective and safe therapeutic option in patients with mycotic aneurysm originating from the subclavian artery. © 2010 Wiley‐Liss, Inc. 相似文献

OBJECTIVES: The purpose of this study was to evaluate the results of endovascular treatment of symptomatic vertebrobasilar insufficiency unresponsive to medical therapy. METHODS: Twenty-eight patients who were regularly followed up in our cardiology clinic with symptoms suggestive of posterior fossa ischemia and with diagnostic or suspicious findings on ultrasound evaluation were evaluated with selective vertebral and subclavian artery angiography. All patients (17 men, 11 women; mean age, 64 years; range, 54-87) had critical lesions (>70% stenosis) in the vertebral or subclavian arteries or both. Those lesions that were considered severe enough to explain the reported symptomatology underwent percutaneous intervention and stent placement. All patients were followed up through clinic visits for a mean of 14.2 months (range, 3.5-24.3). RESULTS: In the 28 patients treated, 25 vertebral and 10 subclavian stents were placed. Success (<20% residual diameter stenosis, without stroke or death) was achieved in 27 patients (96%). One patient who had been undergoing intervention for a subtotal occlusion of the left subclavian artery developed a posterior fossa transient ischemic attack. At follow-up, 25 patients (89%) were alive, and 22 (88%) of those had no further neurological complaints. Three (11%) patients died during follow-up from cardiac complications. One (3.5%) patient had recurrent symptoms with in-stent restenosis at 6 months with successful balloon angioplasty and resolution of symptoms. CONCLUSIONS: Posterior fossa ischemia is an underdiagnosed condition that occurs with relative frequency in the usual patient population that interventional cardiologists attend to. Endovascular treatment using coronary wires and stents including drug-eluting stents is the treatment of choice for vertebral artery revascularization due to its high technical success rate, low complication rate, and long-term durability. 相似文献

The purpose of this study is to report the progress of a patient who entered the hospital with symptomatic tracheal compression from a large right subclavian artery aneurysm that was treated with a self-expanding stent graft. The patient was at increased risk for traditional surgery, thus endovascular isolation of the aneurysm was felt to be reasonable. A flexible self-expanding stent graft was placed via a brachial artery cutdown and common femoral access without complication. The symptoms improved and the patient remained asymptomatic at 2-year follow-up with serial CT scan confirmation of aneurysm regression. This unusual case illustrates that endovascular decompression of an aneurysm may have some benefit in alleviating subacute symptoms of extrinsic encroachment into other vital structures. Technical and clinical success was achieved with the stent graft deployment and this seems to be a reasonable alternative to surgery in such patients. 相似文献

We report the unusual case of a 66-year-old alcoholic male who presented with acute arm ischemia 4 months following ipsilateral subclavian artery stenting. The patient had a petechial rash and Janeway lesions in the distribution of the affected subclavian artery. He had been treated for an infected dialysis graft 10 days prior to entry into the hospital. Subsequent angiogram confirmed a patent stent with intraluminal filling defects and occlusion of the brachial artery. Thrombectomy yielded material that was consistent with septic emboli and CT scan of the chest was suggestive of a mycotic aneurysm around the stent. The subclavian stent was removed surgically and the aneurysm was repaired. Unfortunately, the patient had multiple comorbidities and died of complications during recovery. This is the first case of a subclavian stent infection following septicemia remote from implantation. 相似文献
