[Cerebral revascularisation in Takayasu's arteritis]

Area of Science:

• Vascular Surgery
• Neurology
• Rheumatology

Context:

• Takayasu's arteritis frequently involves long arterial segments, rendering angioplasty unfeasible.
• Cerebral ischemia is a significant complication of Takayasu's arteritis.
• Surgical intervention plays a vital role in managing cerebral ischemia in these patients.

Purpose:

• To define indications and surgical techniques for head artery lesions in Takayasu's arteritis.
• To present surgical experience with seven patients suffering from cervical arterial lesions due to Takayasu's arteritis.

Summary:

• Seven patients with Takayasu's arteritis underwent bypass surgery for cervical arterial lesions.
• Procedures included aorta-to-carotid and brachiocephalic-to-carotid bypasses.
• Outcomes varied, with some patients showing significant improvement, while others experienced bypass thrombosis or complications like cerebral hemorrhage.

Impact:

• Highlights the importance of surgical treatment for cerebral ischemia in Takayasu's arteritis.
• Suggests that operative indications should consider cerebral blood flow assessment.
• Emphasizes the risk of cerebral hyperperfusion syndrome and the benefit of staged revascularization.
