Summary

Intraoperative aneurysm rupture at the neck is a serious complication. Proper clip placement parallel to the parent artery and temporary clipping can reduce risks in fragile or recurrent aneurysms.

Area of Science:

  • Neurosurgery
  • Vascular Surgery

Background:

  • Intraoperative rupture of cerebral aneurysms, particularly at the neck, can lead to severe outcomes.
  • This study focuses on two cases of intraoperative rupture at the aneurysm neck during surgical clipping.

Observation:

  • Aneurysm rupture occurred during clipping in two patients, necessitating microvascular repair and resulting in neurological deficits.
  • One case involved a broad-based A1 aneurysm with a wide, thin neck, and the other a recurrent internal carotid artery-posterior communicating artery aneurysm.

Findings:

  • Aneurysm neck fragility in thin-walled or recurrent aneurysms poses a significant surgical challenge.
  • Suboptimal clip application (perpendicular to the parent artery) contributed to rupture in one case.

Implications:

Related Experiment Videos

  • Surgical clipping of fragile or recurrent aneurysms requires careful technique, emphasizing parallel clip placement to the parent artery.
  • Temporary clipping during dissection and clip application is advisable to minimize neck damage and reduce rupture risk.
