Summary

Aneurysmal rests after clipping are dangerous and underestimated. Intraoperative angiography helps avoid these, but treatment decisions for rests depend on patient factors, surgeon experience, and re-operation considerations.

Area of Science:

  • Neurosurgery
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Aneurysmal rests, though uncommon after surgical clipping for brain aneurysms, pose significant risks.
  • These rests are often underestimated, necessitating a clear classification and understanding of their management.
  • Existing literature lacks consensus on the optimal treatment strategies for post-clipping aneurysmal rests.

Purpose of the Study:

  • To classify aneurysmal rests based on morphology, clip relationship, and size.
  • To analyze the evolution and risks associated with aneurysmal rests.
  • To discuss factors influencing treatment decisions and re-operation strategies for aneurysmal rests.

Main Methods:

  • Classification of aneurysmal rests by morphology (neck/sac involvement), clip proximity (proximal/distal), and size (<2mm, 2-4mm, >4mm).

  • Categorization of rests from a surgical perspective: unavoidable, avoidable, and intentional.
  • Literature review on aneurysmal rest evolution and risks, emphasizing intraoperative angiography's role.

    • Main Results:

    • Aneurysmal rests can be classified systematically, aiding in understanding their nature.
    • Intraoperative angiography is crucial for preventing the formation of aneurysmal rests.
    • Treatment decisions for aneurysmal rests are multifactorial, involving patient age, prior treatment, rest characteristics, and available therapies.

    Conclusions:

    • Aneurysmal rests require careful consideration due to their potential dangers.
    • Intraoperative angiography is a key tool in minimizing the occurrence of aneurysmal rests.
    • Personalized treatment strategies, including surgical re-intervention and endovascular options, are essential for managing aneurysmal rests.
