Microsurgical excision of a ruptured distal lenticulostriate aneurysm in a child.

Distal lenticulostriate artery aneurysms are rare but potentially fatal conditions, especially in children. Endovascular management is often considered the first-line treatment, but microsurgical excision may be necessary in certain cases. This article presents a case report of a child with a ruptured distal lenticulostriate artery aneurysm that required careful decision making and preparation before microsurgical excision.

[Unruptured asymptomatic brain aneurysms: modern approaches to the choice of surgical method and treatment outcomes].

Background: In recent years, significant attention has been paid to preventive vascular neurosurgery. Treatment of unruptured asymptomatic brain aneurysms is one of the sections of this surgery.

Objective: To evaluate treatment outcomes in patients with unruptured asymptomatic brain aneurysms who underwent treatment chosen on the basis of criteria adopted at the Burdenko Neurosurgery Center.

[Surgical treatment of vertebral artery confluence aneurysms].

Background: Aneurysms of vertebral artery confluence and proximal parts of basilar artery are extremely rare. They are usually combined with proximal fenestration of basilar artery. No timely surgical treatment of these aneurysms is associated with high risk of adverse outcomes, and their treatment is a challenge for neurosurgeons.

[Combination of pituitary adenomas and intracranial aneurysms].

The combination of intracranial tumors and asymptomatic brain aneurysms is an urgent problem, since it can significantly affect surgical intervention. Aneurysms are common in patients with meningioma, glioma and pituitary adenoma. According to certain authors, combination of aneurysms with pituitary adenomas is 7 times more common than with other tumors.

[Combination of infraoptic anterior cerebral artery with an aneurysm of the ACA-AcomA complex. Case study and literature review].

The infraoptic anterior cerebral artery (ACA) is an abnormal vessel that usually is a bifurcation of the intradural part of the internal carotid artery (ICA) or near the site of discharge of the ophthalmic artery, which passes under the ipsilateral optic nerve and penetrates between the optic nerves into the prechiasm cistern, reaching the ACA-AcomA complex. The infra-optic ACA is an extremely rare anomaly, but it may be of great clinical significance in surgery of the arteries of the anterior sections of the Willis circle. The article describes the case of a combination of infra-optical ACA with an aneurysm of the ACA-AcomA complex.
