Aneurysms of the vascular wall represent a final common pathway for a number of inflammatory processes, including atherosclerosis and idiopathic vasculitis syndromes. Kawasaki disease (KD) is an acute, self-limited vasculitis in children and the leading cause of acquired coronary artery aneurysms. We sought to identify shared molecular mechanisms of aneurysm ...

Ruptured aneurysms of < 2 mm are not amenable to endovascular coiling and therefore pose a significant treatment challenge. To test recently introduced flow diverters that allow endovascular reconstruction via another method and may represent a new treatment option for such lesions. Three female patients presented with acute subarachnoid hemorrhage. ...

BACKGROUND: Previous studies on aneurysms in Nigeria have either been case reports or studies of peripheral aneurysms. No study has comprehensively evaluated all aspects of this disease as an entity among Nigerians. The need therefore arises to re-evaluate this lesion so as to make deductions on incidence, sex ratio, aetiology ...

Large to giant middle cerebral artery aneurysm is a challenging disease, especially when incorporating important perforating arteries. Surgical risk increases by perforator infarction and anatomical complexity. In this clinical setting, extensive consideration of surgical options is needed. The two cases described here were unruptured and had rather stable wall. Because ...

Partially thrombosed intracranial aneurysms (PTIAs) are different from saccular or nonthrombosed giant or large aneurysms, as they are characterized by multiple intramural thrombotic phenomena related to recurrent vessel wall dissections. We retrospectively reviewed clinical and radiological files of 23 consecutive patients with PTIAs (mean age 49.3 years). Twenty-two lesions were ...

Giant serpentine aneurysms are rare and have distinct angiographic findings. The rarity, large size, complex anatomy and hemodynamic characteristics of giant serpentine aneurysms make treatment difficult. We report a case of a giant serpentine aneurysm of the right middle cerebral artery (MCA) that presented as headache. Treatment involved a superficial ...

Multiple intracranial aneurysms located bilaterally in the anterior circulation are usually clipped sequentially by separate craniotomies or a bilateral craniotomy. However, in selected patients, bilateral aneurysms can be clipped on both sides in a single sitting through a unilateral approach and unilateral craniotomy without causing morbidity. We present our technique ...

The size of elastase-induced aneurysms created in the usual way is relatively small. Our aim was to determine whether creation of a carotid-jugular AVF to induce remodeling of the RCCA results in larger elastase-induced aneurysms in rabbits. RCCA right-jugular AVFs were created in 6 New Zealand white rabbits (group 1), ...

Pediatric aneuryms are rare and have characteristics that distinguish them from their adult counterparts. There is a greater capacity for pediatric aneurysms to arise de novo and progress rapidly. Saccular aneurysms are rarer; fusiform/giant aneurysms are more common. Hemorrhage is less common at presentation than are symptoms that result from ...

The quality of surgical treatment of intracranial aneurysms is determined by complete aneurysm occlusion and restoration of flow in the parent, branching and perforating vessels. In postoperative digital subtraction angiography (DSA), unexpected aneurysm residuals and vessel occlusions are frequently detected. Here, the value of two nearly noninvasive and cost-effective techniques ...

A 40-year-old female presented with sudden onset of severe headache and vomiting due to subarachnoid hemorrhage. Angiography demonstrated a saccular aneurysm on a dolichoectatic left middle cerebral artery (MCA) and delayed filling of the MCA. Magnetic resonance imaging showed a partially thrombosed giant aneurysm on the dolichoectatic MCA. An intentionally ...

Cerebral aneurysms are commonly named based on their relationship with adjacent vessels in either the anterior or posterior circulation. Although such an approach has long proved useful, this terminology does not take into account potential hemodynamic forces or aneurysm wall properties that are likely to be important for cerebral aneurysm ...

Surgical clipping may cause stenosis of parent arteries or occlusion of perforating arteries in cerebral aneurysm surgery. To prevent postoperative motor deficits, motor-evoked potentials (MEPs) have been used. This enables to detect cerebral ischemia. However, the rate of false negatives (motor deficits with preserved MEP) has been relatively higher than ...
