Delayed surgery for ruptured pericallosal aneurysms in 19 patients led to excellent or good outcomes in 94% of cases. This approach improved neurological status before intervention, minimizing operative risks.

Area of Science:

  • Neurosurgery
  • Vascular Neurology
  • Neuroradiology

Background:

  • Pericallosal aneurysms are a significant cause of subarachnoid hemorrhage.
  • Ruptured aneurysms carry a high risk of rebleeding and poor neurological outcomes.

Purpose of the Study:

  • To evaluate the outcomes of delayed surgical intervention for pericallosal aneurysms.
  • To assess the impact of delayed surgery on patient neurological status and functional recovery.

Main Methods:

  • Retrospective review of 19 patients with pericallosal aneurysms over 10 years.
  • Analysis of surgical timing, neurological grades (Hunt and Hess), and patient outcomes.
  • Correlation of delayed surgical intervention with neurological status improvement and functional results.

Main Results:

  • 18 of 19 patients had ruptured aneurysms; one was asymptomatic.
  • 16 patients underwent delayed surgery (average 25 days post-hemorrhage), with improved neurological grades.
  • Excellent outcomes (69%) and good outcomes (25%) were achieved in 94% of operated patients, with no operative mortality or morbidity.

Conclusions:

  • Delayed surgical management of pericallosal aneurysms can be safe and effective.
  • Operating in a better neurological state post-hemorrhage improves functional outcomes.
  • This strategy offers a favorable risk-benefit profile for selected patients.
