Surgical outcomes in aneurysms of the basilar trunk and vertebrobasilar junction

Takeaway

  • Surgery is recommended to increase the survival of giant fusiform and dolichoectatic aneurysms of the basilar trunk and vertebrobasilar junction (BTVBJ-GFDA) and should be performed under a narrow treatment window according to blood flow.

Why this matters

  • BTVBJ-GFDA is a rare occurrence, and detailed mechanisms of development are unknown.

  • Surgical treatment for BTVBJ-GFDA is difficult due to location of the aneurysm, and there are few studies with positive outcomes; therefore, it is unknown which factors contribute to positive surgical outcomes.
