The authors report a case of a posterior inferior cerebellar artery origin aneurysm causing brainstem compression and swallowing difficulty. The patient had an ipsilateral microvascular decompression of cranial nerve VII for hemifacial spasm 27 years prior to the discovery of the aneurysm. The aneurysm was successfully treated endovascularly. A discussion ...

We describe the use of multiple Amplatzer vascular plugs which were intentionally placed so as to isolate a large azygous vein aneurysm with intraluminal thrombosis, which had resulted in a previous pulmonary embolus. This technique avoided the need for an invasive thoracotomy and aneurysm resection or attempting to directly fill ...

Macular edema is a common cause of visual loss in patients with retinal vein occlusions. Ozurdex(®), a dexamethasone intravitreal implant, has been shown in randomized controlled trials to reduce macular edema and improve visual acuity in patients with either branch retinal vein occlusions or central retinal vein occlusions. It was ...

Although hypoxic pulmonary vasoconstriction is a well-recognized physiological phenomenon it is unusual to observe and assess its efficiency in clinical practice. Here, we report the case of a 50-year-old female who presented with unilateral incomplete bronchial occlusion due to a carcinoid tumor involving the left main bronchus in the absence ...

Transient adenosine-induced asystole is a reliable method for producing a short period of relative hypotension during surgical and endovascular procedures. Although the technique has been described in the endovascular treatment of brain arteriovenous malformations, aortic aneurysms, and posterior circulation cerebral aneurysms, little description of its use in anterior circulation aneurysms ...

An intracranial posterior circulation revascularization procedure in the form of a side-to-side in situ posterior inferior cerebellar artery (PICA)-PICA bypass operation was introduced in 1991. This elegant and apparently low-risk operation is performed infrequently. Thus, the operative nuances used in this procedure have not been well reported, limiting the scope ...

Unlike posttraumatic temporal artery aneurysm, spontaneous temporal artery aneurysm is an exceptional finding. We report the case of a 34-year-old woman with no history of previous trauma who presented a progressively enlarging right temporal lump. A CT scan revealed a 1.6cm diameter aneurysm arising from the superficial temporal artery. The ...

Fusiform anterior communicating artery (ACoA) aneurysms (ACoAAs) are rare, and a series of these aneurysms has not been reported. Large fusiform ACoAA are easily identifiable, whereas smaller ones can coexist with a saccular component. To provide a clear-cut definition, report the incidence of these aneurysms, present a series with follow-up ...

The incidence of ischemia might be increased in the surgical repair of atherosclerotic unruptured aneurysms compared to non-atherosclerotic aneurysms. The atherosclerotic wall might increase the occurrence of thrombembolic events or its rigidity might endanger the occlusion of perforators within the aneurysm vicinity. 87 patients (53 patients without and 34 patients ...

Flow-diverting approaches to intracranial aneurysm treatment had many promising early results, but recent apparently successful treatments have been complicated by later aneurysm hemorrhage. We analyzed 7 cases of aneurysms treated with flow diversion to explore the possible rupture mechanisms. CFD analysis of pre- and posttreatment conditions was performed on 3 ...

FD technology enables reconstructive repair of otherwise difficult-to-treat intracranial aneurysms. These stentlike devices may induce progressive aneurysm thrombosis without additional implants and may initiate complete reverse vessel remodeling. The associated vascular biologic processes are as yet only partially understood. From 12 different centers, 13 cases of delayed postprocedural aneurysm rupture ...

Intracranial aneurysms may be treated by flow diverters, alternatively to stents and coils combination. Numerical simulation allows the assessment of the complex nature of aneurismal flow. Endovascular devices present a rather dense and fine strut network, increasing the complexity of the meshing. We propose an alternative strategy, which is based ...

Optimal treatment of intracranial aneurysms involves complete occlusion of the aneurysm with preservation of the parent artery and all of its branches. Attempts to occlude the aneurysm and preserve the parent artery may be associated with a higher level of risk than parent vessel occlusion or trapping. To evaluate our ...

Aneurysms of the anterior inferior cerebellar artery (AICA) are a rare entity. Purely intrameatal aneurysms are even rarer. The authors report an intrameatal thrombosed AICA aneurysm mimicking a vestibular schwannoma that was treated by resection and end-to-end anastomosis. This 22-year-old man presented with acute hearing loss, vertigo, and moderate facial ...

The choice of the experimental aneurysm model is essential for valid embolization-device evaluations. So far, the use of the rabbit venous pouch arterial bifurcation aneurysm model has been limited by demanding microsurgery, low aneurysm patency rates, and high mortality. This study aimed to facilitate microsurgery and to reduce mortality by ...

Generally speaking, the term "ophthalmic aneurysms" refers to carotid-ophthalmic aneurysms, which arise from the internal carotid artery (ICA) wall at or around the origin of the ophthalmic artery (OA). In contrast, aneurysms arising from the OA stem or its branches, separate from the ICA are called peripheral OA aneurysms (POAAs). ...

Visceral artery aneurysms (VAA) are relatively rare disease patterns. With regard to the aetiology two different entities of VAA can be distinguished: (i)  real VAA, where arteriosclerosis plays an important role, particular in elderly patients, and (ii)  pseudo-aneurysms. Here, previous abdominal trauma or former inflammatory processes are considered to be ...
