Rates of development of de novo intracranial aneurysms and of growth of untreated additional aneurysms are largely unknown. We performed MRA in a large patient cohort with coiled aneurysms at 5-year follow-up. In 276 patients with coiled intracranial aneurysms and 5±0.5 years of follow-up MRA (totaling 1332 follow-up patient-years), additional ...

BACKGROUND:: Intraprocedural rupture is a dangerous complication of endovascular treatment. Small ruptured anterior communicating artery (AcoA) aneurysms and microaneurysms present a challenge for both surgical and endovascular therapies to achieve obliteration. An understanding of the complication rates of treating ruptured AcoA microaneurysms may help guide therapeutic options. OBJECTIVE:: To report ...

Endoluminal reconstruction with flow diverting devices represents a novel constructive technique for the treatment of cerebral aneurysms. We present the results of the first prospective multicenter trial of a flow-diverting construct for the treatment of intracranial aneurysms. Patients with unruptured aneurysms that were wide-necked (>4 mm), had unfavorable dome/neck ratios ...

An infrequent case of a de novo aneurysm formation originating from an infundibulum at the origin of the posterior communicating artery (PcomA) is presented. The aneurysm developed within 7 years in a patient who initially presented with subarachnoid hemorrhage (SAH) from a saccular aneurysm of the vertebral artery. A 43-year-old ...

Because of their fragile and thin wall, ruptured blood blister-like aneurysms (BBAs) at the anterior wall of the internal carotid artery (ICA) are difficult to manage, both surgically, as well as endovascularly. BBA is usually a tiny and broad-necked aneurysm, but it occasionally demonstrates a relatively saccular-like shape. In addition, ...

Polyglycolic-polylactic acid (PGLA) coils induce inflammation within a cerebral aneurysm, which in turn is hypothesized to decrease aneurysm recurrence. We present 2 patients, who after aneurysm coiling with PGLA coils, developed mild symptoms and extensive magnetic resonance imaging (MRI) white matter changes. The first patient was a 46-year-old woman who ...

Polyarteritis nodosa (PAN) is a vasculitis, which often involves small and medium sized visceral arteries. This condition may result in multifocal aneurismal formation and end-organ damage. Uncommonly, PAN may present with rupture of hepatic artery aneurysms. Here, we report a rare case of a ruptured intrahepatic aneurysm associated with PAN. ...

Subarachnoid hemorrhage (SAH) accounts for ~5% of strokes, but causes high rates of morbidity and mortality and occurs at a relatively young age. The rupture of an intracranial aneurysm is the leading cause of nontraumatic SAH and will be the subject of this review. Rebleeding remains the most imminent danger ...

Delayed intra-abdominal hemorrhage after pancreatic surgery is a potentially lethal complication. Transarterial coil embolization and/or the placing of an endovascular stent are minimally invasive and effective procedures. An artery that is extensively eroded and rendered friable due to operative skeletonization or postoperative inflammation sometimes contributes to delayed intra-abdominal hemorrhage or ...

We performed a systematic review of the literature to establish whether revascularisation of the left subclavian territory is necessary when this artery is covered by a stent. We retrieved data from 99 studies incorporating 4906 patients. Incidences of left-arm ischaemia (0.0% vs 9.2%, p=0.002) and stroke (4.7% vs 7.2%, p<0.001) ...

Atherosclerosis of the brachiocephalic vessels is uncommon in comparison to the prevalence of disease in the extracranial carotid arteries. Prior to 1980, occlusive disease of this vascular bed had been treated primarily with surgical intervention, which carried a significant rate of morbidity and mortality. In the last 30 years, however, ...

Subclavian artery dissection is a rare complication of cardiac catheterization. The usual reason for entering this vessel is to access the origin of the left internal mammary artery (LIMA) when this has previously been used, or is being considered, as a bypass graft. We report an instance of such dissection ...

Severe aortic valve stenosis may be tackled with percutaneous aortic valve replacement instead of surgical replacement. At present, two CE marked prosthetic valves are available. The CoreValve ReValving System is primarily designed to be introduced transfemorally, while implantation via subclavian arteries has been described in cases of unsuitable femoral access. ...

Venous complications of thoracic outlet obstruction are frequently the result of acute axillosubclavian vein thrombosis, leading to symptoms consistent with venous claudication, including pain, swelling, and cyanotic discoloration. Nonthrombotic subclavian vein obstruction, however, is an uncommon cause of veno-occlusive symptoms. We report the case of a patient who, while running, ...

Bilateral thalamic infarction is a very rare affection. We report here a case of bithalamic infarction during subclavian catheterization related to the accidental migration and complete occlusion of an arterial embolism to the Percheron's artery. Percheron's artery is an anatomical variation described in 1977, constituted by a solitary arterial trunk ...

A non-recurrent inferior laryngeal nerve (NRILN), a very rare anatomic variation, is easily damaged during thyroid surgery. Due to impairments during embryonic development, a NRILN is frequently associated with an aberrant subclavian artery. Thus, an aberrant subclavian artery is now regarded as an important vascular anomaly for predicting the presence ...
