Dolichoarteriopathies consist of tortuosity, kinking, or coiling of the extracranial carotid arteries. Some authors consider these alterations a consequence of atherosclerotic vessel remodeling, while others ascribe them to anatomical variations of embryological origin. The objective was to establish whether carotid dolichoarteriopathies belonged to a congenital origin or to acquired conditions. ...

OBJECTIVE: We developed a new liquid embolic agent, an aqueous solution of thermoreversible gelation polymer (TGP) for the treatment of cerebral aneurysms. This polymer solution has the unique characteristics that allow it to solidify at a specific temperature without solvent. We performed an experimental aneurysm embolization using this liquid embolic ...

Endovascular repair of aortoiliac artery aneurysm is a safe and effective treatment strategy. Selective hypogastric artery embolization with coils may be necessary to allow the endograft to anchor in the aneurysm-free external iliac artery, thereby eliminating hypogastric endoleak into the aortoiliac aneurysm. Considerable controversy exists regarding the safety of intentional ...

There is considerable interest in the development of symptomatic inflammatory reactions following coil embolization of cerebral aneurysms. Patients have experienced a range of adverse events, usually after treatment of moderately large aneurysms with modified "bioactive" coils. More recently, it has been recognized that adverse inflammatory reactions can be associated with ...

Renal artery aneurysms are more common in patients with fibromuscular dysplasia (FMD). Although these aneurysms have traditionally been managed surgically, endovascular techniques are playing a larger role. Many treatment methods involve the use of stent-grafts to exclude the aneurysm or bare stents to protect the main renal artery while coil ...

Endovascular, endosaccular, coil embolization has emerged as an established therapy for both ruptured and unruptured cerebral aneurysms. However, many aneurysms are not cured using conventional endovascular techniques. Coil embolization often results in incomplete aneurysm occlusion or recanalization in the ensuing months after treatment. The Pipeline embolization device (PED; Chestnut Medical) ...

BACKGROUND AND PURPOSE: The proportion of incompletely occluded aneurysms after coiling varies widely between studies. To assess overall outcome of coiling, we systematically reviewed the literature to determine initial occlusion, reopening, and retreatment rates of coiled aneurysms according to predefined criteria and subgroups. METHODS: We searched PubMed and EMBASE (January ...

Aneurysm embolization using Guglielmi detachable coils (GDC) is gaining acceptance as a viable alternative for surgery in the treatment of aneurysms. Recent reports describe a significant rate of thromboembolic complications. Thalamic and midbrain blood supply can arise from complex anatomical variations. The rare variation: "artery of Percheron", is a solitary ...

Endovascular coiling of small, ruptured intracranial aneurysms is controversial because of technical difficulties. We analyzed the clinical and angiographic effects of endovascular treatment of 39 small (5mm) ruptured intracranial aneurysms (in 37 patients) at our institution between March 2004 and March 2007. Procedures were carried out on a biplane angiographic ...

OBJECTIVE: Because of their anatomic configuration, middle cerebral artery (MCA) aneurysms are most often treated with surgical clipping. However, endovascular coil embolization of these aneurysms is an increasingly used alternative. We retrospectively reviewed the anatomic and clinical outcomes of patients with MCA aneurysms who underwent endovascular treatment at our institution. ...

Although endovascular treatment has been proved to be as effective as surgical clipping in the prevention of rebleeding of ruptured aneurysm, early rebleeding after coil embolization has seldom been reported. We experienced early rehemorrhage in two patients of ruptured small anterior communicating artery aneurysms of complete treatment with coil-embolization initially. ...
