Meningiomas associated with intracranial aneurysms are very rare. The co-existence of both lesions is not only a diagnostic challenge but also has important therapeutic implications. We analyzed our experience of five such patients, the second largest group in the literature. All the lesions were successfully managed surgically. All the patients ...

A 56-year-old woman with adult idiopathic thrombocytopenic purpura (ITP) diagnosed 17 years previously presented with a fusiform aneurysm manifesting as chronic headache. She had suffered no major hemorrhagic complications, although her platelet counts were between 3.0 x 10(9)/l and 50.0 x 10(9)/l. Magnetic resonance angiography identified a fusiform aneurysm of ...

Studying the flow dynamics of intracranial aneurysms and the associated pulsatility of the aneurysm wall may help to risk-stratify unruptured aneurysms. Currently, in-vivo methods that visualize aneurysm wall movement at high temporal resolution are not yet fully established. We describe a patient with an intracavernous aneurysm in whom the area ...

Distal choroidal artery aneurysms stemming from the lateral wall of the ventricles are rare and are mostly associated with moyamoya disease. The treatment of these aneurysms is difficult because of their deep location. The authors report the case of a 50-year-old woman followed for moyamoya disease presenting with 2 intraventricular ...

We present a case of a male patient diagnosed with a large inferior pancreaticoduodenal artery (IPDA) aneurysm, associated with a fresh thrombotic occlusion of the celiac trunk. Given the risk of splanchnic ischaemia, radiologic embolisation of the aneurysm combined with celiac axis stenting was deemed unsafe. Management was therefore modified ...

A 31-year-old woman with neurofibromatosis type I (NF-I) came to our hospital with hypotension and abdominal pain. A computed tomography (CT) scan showed blood in the retroperitoneum and two saccular aneurysms in the superior mesenteric artery (SMA). The largest measured 2.5 cm in diameter. She was treated with placement of ...

Fenestration is a vascular variation that begins with a common origin, then splits into two parallel luminal channels and rejoins distally. Potential association between anomalies of cerebral circulation and increased occurrence of aneurysm makes intracranial arterial fenestrations important. The planning of intracranial arterial interventions may be complicated if a fenestration ...

Intracranial aneurysms have been induced in mice, rats, rabbits, and primates through carotid artery ligation. We reviewed our experience with RCCA ligation to quantify the rate of aneurysm formation in rabbits. In 30 consecutive New Zealand white rabbits, the RCCA was ligated during surgery to create elastase-induced aneurysms. The basilar ...

Multiple giant coronary artery aneurysms are rare but can develop in the presence of an underlying atherosclerotic vessel disease. Nevertheless, there is no consensus on the ideal surgical treatment or on operative procedures, including aneurysm resection, ligation, distal bypass, and graft interposition. We present the case of a 72-year-old woman ...

OBJECTIVE: With improvements in endovascular techniques, fewer aneurysms are treated by surgical clipping, and those aneurysms targeted for open surgery are often complex and difficult to treat. We devised a hollow, 3-dimensional (3D) model of individual cerebral aneurysms for preoperative simulation and surgical training. The methods and initial experience with ...

Surgical treatment of posterior inferior cerebellar artery (PICA) aneurysms is challenging due to limited surgical accessibility. Endovascular approach has a benefit of avoiding direct injury to the brainstem or lower cranial nerves. Therefore, it has recently been considered an alternative or primary modality for PICA aneurysms. We retrospectively assessed outcomes ...

Intracranial aneurysms are sometimes presented with visual symptoms by their rupture or direct compression of the optic nerve. It is because their prevalent sites are anatomically located close to the optic pathway. Anterior communicating artery is especially located in close proximity to optic nerve. Aneurysm arising in this area can ...

Behçet's disease is the most common cause of pulmonary artery aneurysms. Pulmonary artery aneurysms are rare, but they are life-threatening because of their high tendency to rupture. However, there is also a chance that the aneurysms may completely resolve with immunosuppressive therapy. A 30-year-old man was admitted with chest pain, ...

BACKGROUND: Microneurosurgical technique and anatomical knowledge require extensive laboratory training before mastering these skills. There are diverse training models based on synthetic materials, anesthetized animals, cadaver animals, or human cadaver. Human cadaver models are especially beneficial because they are the closest to live surgery with the greatest disadvantage of lacking ...

OBJECTIVE: No existing in vivo technique can measure aneurysm wall thickness for evaluation of rupture risk. Intracranial aneurysms produce bruits at a special range of frequency that are highly influenced by the wall thickness. Understanding of the mechanism that generates bruits may allow us to learn aneurysm behavior non-invasively. METHODS: ...
