Multiple cerebral aneurysms associated with Takayasu arteritis successfully treated with coil embolization

Area of Science:

• Neurology
• Vascular Surgery
• Interventional Radiology

Background:

• Takayasu arteritis (TA) is a large vessel vasculitis primarily causing occlusive cerebrovascular lesions.
• Cerebral aneurysms are infrequent complications of TA, with limited reported cases.
• Endovascular treatment of TA-associated cerebral aneurysms has not been previously documented.

Observation:

• A case of TA presented with a basilar tip aneurysm and a left posterior cerebral artery P1 segment aneurysm.
• These aneurysms were successfully treated using endovascular coil embolization.
• Catheter navigation through the tortuous vasculature associated with TA posed significant challenges.

Findings:

• Coil embolization is a viable treatment option for cerebral aneurysms in Takayasu arteritis.
• Successful embolization required meticulous selection and navigation of endovascular tools.
• The tortuous vascular anatomy in TA necessitates advanced interventional techniques.

Implications:

• This case expands the endovascular treatment options for rare cerebrovascular complications of Takayasu arteritis.
• It underscores the importance of specialized catheter skills for managing complex vascular anatomies in TA patients.
• Further research may explore the long-term efficacy and safety of endovascular techniques in TA-associated aneurysms.
