[Comparative studies on early and late operations in aneurysm surgery]

Area of Science:

• Neurosurgery
• Neurology
• Vascular Surgery

Background:

• Subarachnoid hemorrhage (SAH) from ruptured aneurysms is a critical neurological emergency.
• Optimal timing for surgical intervention remains a key consideration in managing aneurysmal SAH.
• Intracerebral hemorrhage (ICH) associated with aneurysms presents unique management challenges.

Purpose of the Study:

• To evaluate the outcomes of early versus delayed surgical treatment for angiographically verified aneurysms.
• To assess the incidence of rebleeding in patients undergoing operative treatment.
• To analyze the outcomes of patients with space-occupying intracerebral hemorrhage due to ruptured aneurysms.

Main Methods:

• A retrospective analysis of 241 patients with aneurysms treated surgically between January 1979 and December 1983.
• Patients were categorized based on preoperative grading using the Hunt and Hess scale.
• Postoperative outcomes were assessed using the Glasgow Outcome Score (GOS) at six months.
• Surgical timing was classified as early (within 72 hours) or delayed.

Main Results:

• A total of 241 patients underwent surgery for verified aneurysms.
• 88 patients had early surgery (within 72 hours), and 153 had delayed surgery.
• Outcomes were evaluated based on the Hunt and Hess scale and Glasgow Outcome Score.
• Data on rebleeding rates and outcomes in cases of intracerebral hemorrhage were collected.

Conclusions:

• The study provides long-term outcome data for surgical aneurysm treatment.
• Findings contribute to understanding the impact of surgical timing on patient outcomes.
• The research highlights factors influencing recovery after ruptured aneurysms, including hemorrhage severity.
