Summary
Rare lenticulostriate artery aneurysms in moyamoya disease pose risks. Surgical occlusion of the affected artery successfully treated a fusiform aneurysm without causing stroke in this patient.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Neurology
Background:
- Saccular aneurysms originating from lenticulostriate arteries are uncommon.
- Occluding lenticulostriate arteries is generally avoided due to infarction risks.
Purpose of the Study:
- To describe the successful surgical management of a rare fusiform aneurysm of a lenticulostriate artery in a patient with moyamoya disease.
Main Methods:
- Image guidance was crucial for precise aneurysm localization.
- The lenticulostriate artery feeding the aneurysm was occluded using a surgical clip.
Main Results:
- The surgical procedure successfully obliterated the aneurysm.
- The patient tolerated the lenticulostriate artery occlusion without experiencing an ischemic stroke.
Conclusions:
- Surgical occlusion of a lenticulostriate artery can be a safe and effective treatment for associated aneurysms, even in moyamoya disease patients.
- Careful surgical planning and image guidance are essential for managing these rare vascular lesions.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
