Impact of double stent retriever configuration on first-pass effect in stroke: a multicenter study.

Background: Efficient recanalization of occluded cerebral arteries is crucial in the treatment of acute ischemic stroke. Double stent retrievers have shown the potential to enhance the rates of recanalization on the first pass. This study aims to evaluate the efficacy and safety of the double stent retriever technique and the predictors of achieving first-pass effect in patients with acute ischemic stroke.

Frozen Shoulder.

Adhesive capsulitis (AC) develops spontaneously without a known cause and is a common cause of painful shoulder. The natural history of AC can last until 36 months and it is classically considered a self-limiting entity, however there is a high rate of refractory cases to conventional treatment with residual deficits during years. There is no consensus on the therapeutic guidelines to be followed in patients with AC.

To present the outcomes of endovascular treatment of diabetics patients with critical limb ischemia who have end-stage renal disease. Limb-salvage was achieved in 58.6% of the limbs during a mean follow-up period of 12.

Stent-assisted coil embolization of a mycotic renal artery aneurysm by use of a self-expanding neurointerventional stent.

Mycotic aneurysms are uncommon, especially those located in visceral arteries. We present a case of a patient with two visceral mycotic aneurysms due to bacterial endocarditis, one located in right upper pole renal artery and the second in the splenic artery. Both aneurysms were treated as endovascular embolization using microcoils.

Successful occlusion of a ruptured aortic aneurysm using the Amplatzer Vascular Plug: a technical note.

Ruptured abdominal aortic aneurysm is related with a 100% mortality rate if left untreated. Even with surgical intervention or endovascular repair, mortality is still extremely high. However, there are conditions in which neither open surgical aneurysm repair nor endovascular aneurysm repair can be considered a viable therapeutic option because of comorbidities or anatomic reasons.

Infrainguinal revascularization using the Crosser vibrational system.

Revascularization of infrainguinal vessels is still a challenge. Complications such as flow-limiting dissections or perforation are responsible for a limited success rate. Failed revascularization attempt leads to amputation in a significant number of patients and increases mortality.

Non-protected carotid artery stent without angioplasty in high-risk patients with carotid and coronary artery disease undergoing cardiac surgery.

Hemodynamic depression (HD) is a frequent complication related to carotid endartherectomy or carotid artery stenting (CAS), often not well tolerated in patients with coronary artery disease. The purpose of this study is to assess whether CAS without angioplasty is beneficial in patients with severe carotid artery disease before coronary revascularization surgery (CABG) regarding the occurrence of HD. Between October 2002 and August 2006, 39 CAS were performed in 35 patients before cardiac surgery.

Endovascular management of a spontaneous dissecting aneurysm of the superior mesenteric artery: case report and discussion of treatment options.

Spontaneous dissection of the superior mesenteric artery represents a rare cause of abdominal angina. Conservative or more aggressive treatments such as surgery or endovascular therapy depend on the symptoms. We present a case report of acute mesenteric ischemia due to spontaneous dissection of the superior mesenteric artery successfully treated by endovascular stent placement.

Stent-assisted coil embolization of a wide-neck aneurysm of a persistent primitive hypoglossal artery.

Persistent primitive hypoglossal artery (PPHA) represents the second most common carotid-vertebrobasilar anastomosis. The association of PPHA with intracranial aneurysms is not unusual. Treatment of aneurysms located on the PPHA itself is challenging due to the increased risk of ischemic complications secondary to the hypoglossal artery often being the sole contributor of flow to the posterior circulation.

Bilateral hypogastric artery occlusion in endovascular repair of abdominal aortic aneurysms and its clinical significance.

Purpose: Endovascular treatment of aortoiliac aneurysms near or involving the hypogastric artery (HGA) requires HGA occlusion before endografting to avoid retrograde filling of the aneurysm. The purpose of this study is to evaluate clinical outcomes of bilateral HGA occlusion and determine if benefits gained by endovascular aneurysm repair (EVAR) outweigh the morbidity associated with the procedure.

Materials And Methods: Between 1999 and 2004, 128 patients with abdominal aortic aneurysm (AAA) were treated with bifurcated endograft placement.

Endovascular treatment of extracranial internal carotid aneurysms using endografts.

Aneurysms of the extracranial internal carotid artery (EICA) are infrequent. They are difficult to treat with conventional surgery because of their distal extension into the skull base. We report three cases of EICA aneurysms in two symptomatic patients successfully treated with polytetrafluoroethylene self-expanding endografts using an endovascular approach.

[Occlusion of a pulmonary arteriovenous fistula with an amplatzer vascular plug].

Pulmonary arteriovenous malformations are rare anomalies that carry a considerable risk of serious complications such as cerebral thromboembolism or abscess and pulmonary hemorrhage. The first-line treatment of such malformations is detachable coil or balloon embolotherapy. However, coils and balloons may migrate and cause paradoxical embolism especially in malformations with large arteriovenous shunts.

Intraarterial administration of Abciximab for thromboembolic events occurring during aneurysm coil placement.

Background And Purpose: Platelet-derived thrombi may occur during intracranial aneurysm coiling. We report a series of 13 patients treated with intraarterial Abciximab for thrombus formation complicating aneurysm coiling.

Methods: Four patients were treated for acutely ruptured aneurysms.

Balloon-assisted coil placement in wide-neck bifurcation aneurysms by use of a new, compliant balloon microcatheter.

Two types of balloon are usually employed to perform balloon-assisted coil placement in cerebral aneurysms: oval, guide-dependent balloons for sidewall aneurysms and round balloons for bifurcation aneurysms. We report on the use of a new, more compliant, guide-dependent oval balloon microcatheter to seal wide-neck bifurcation aneurysms with coils during endovascular occlusion.
