Persistent sciatic artery (PSA), a persistent embryologic continuation of the internal iliac artery, represents a rare yet clinically important vascular anomaly. PSA is prone to aneurysmal change, which can subsequently lead to distal embolization, sciatic neuropathy, or rupture. The conventional surgical treatment of PSA aneurysms is commonly complex and carries ...

Aneurysms of the extracranial carotid arteries are rare and account for 0.4-1% of all arterial aneurysms and about 4% of all peripheral arterial aneurysms. Causes include atherosclerosis, fibromuscular dysplasia, trauma (penetrating and blunt cervical trauma and hyperextension of the neck), iatrogenic lesions, infection, congenital defects, and irradiation arteritis. Atherosclerosis is ...

Celiac artery aneurysms are extremely rare vascular lesions that are frequently asymptomatic. When present, clinical manifestations are often vague and unspecific. The most serious complication of celiac artery aneurysms is rupture with a mortality rate up to 100%. Elective surgical repair, with a mortality rate of 5%, is recommended except ...

There is a high incidence of intracranial aneurysms of the AcomA suggesting the possibility of an anatomic risk factor. There also exists an association of termination-type aneurysms with anatomic variations of 1 anterior cerebral artery trunk (A1) as the exclusive or dominant supply to both pericallosal arteries (A2). This yields ...

Chondrosarcoma (CSA) of the skull base (SB) is an uncommon, slowly growing, neoplasm comprising approximately 0.1% of all intracranial tumors and 6% of SB lesions. Even though its growth is slow, CSA is a potentially lethal tumor. The therapeutic approach to CSA of the SB is still controversial and clinical ...

OBJECTIVE: Local anatomy and the patient's risk profile independently affect the expansion rate of an abdominal aortic aneurysm. We describe a hybrid method that combines finite element modelling and statistical methods to predict patient-specific aneurysm expansion. METHODS: The 3-D geometry of the aneurysm was imaged with computed tomography. We used ...

Intracranial aneurysm volume and shape are important factors for predicting rupture risk, for pre-surgical planning and for follow-up studies. To obtain these parameters, manual segmentation can be employed; however, this is a tedious procedure, which is prone to inter- and intra-observer variability. Therefore there is a need for an automated ...

Catheter-based intra-arterial digital subtraction angiography (IADSA) is widely trusted for diagnosing cerebral aneurysms. However, three-dimensional CT angiography (3D-CTA) is evolving. This study compares the diagnostic performance and inter-rater reliability of 64-slice 3D-CTA and IADSA. Nineteen patients with 26 suspected cerebral aneurysms (23 with confirmed aneurysms, three negative controls) underwent both ...

The development and validation of methods to stratify the risk of rupture of cerebral aneurysms is highly desired because current treatment risks can exceed the natural risk of rupture. Because unruptured aneurysms are typically treated before they rupture, it is very difficult to connect the proposed risk indices to the ...

We report a case of Hughes-Stovin syndrome (HSS) associated with hyperhomocysteinemia. A 24-year-old man who has no clinical features suggestive of Behcet's disease was admitted for hemoptysis and dyspnea.

True aneurysms of the profunda femoris artery are extremely rare in comparison to pseudoaneurysms of the same artery. In most cases they are accompanied by aneurysms of the abdominal aorta or peripheral vessels. The most common reason for aneurysmic dilatation of vessels is a generalized vascular degenerative process. An isolated ...

Aneurysms in the arteries of the upper extremity are rare but important in predicting aortic aneurysms and their potential to thromboembolize and cause limb loss. Their localization, age, and gender distribution vary between countries depending on ethnic background and cause. These data are valuable in the management of aneurysms, but ...

Fusiform and dolichoectatic aneurysms are challenging lesions to treat with direct clipping. Treatment of these aneurysms often requires alternative surgical strategies, including extracranial-intracranial bypass, wrapping, or clip-wrap techniques. Nonetheless, these alternatives methods of treatment have been underused and frequently overlooked. OBJECTIVE: To report a series of nine cases of otherwise ...
