Perioperative strokes after surgery are rare but serious, with hypertension and atrial fibrillation being key risk factors. These strokes carry a high mortality rate, emphasizing the need for better prediction and prevention strategies.

Area of Science:

  • Neurology
  • Cardiology
  • General Surgery

Background:

  • Perioperative cerebrovascular accidents (strokes) following general surgery are infrequent but carry significant morbidity and mortality.
  • Understanding the contributing factors is crucial for improving patient outcomes.

Purpose of the Study:

  • To identify perioperative, intraoperative, and postoperative factors associated with strokes occurring after general surgical procedures.

Main Methods:

  • A retrospective analysis of 19 patients who experienced a perioperative stroke out of 24,641 general and vascular surgical procedures (0.08%) over five years.
  • Comparison with a matched control group of 19 patients.
  • Exclusion of patients who underwent carotid endarterectomies.

Main Results:

  • The incidence of perioperative stroke was 0.08%, with 53% occurring within 24 hours of surgery.
  • Significant contributing factors included hypertension, smoking, prior neurological symptoms, and abnormal electrocardiogram (ECG) findings, with atrial fibrillation being the most common.
  • The overall perioperative mortality rate was 26%, with long-term poor recovery in a significant portion of survivors.

Conclusions:

  • Perioperative stroke is a devastating complication with a high mortality rate.
  • Cardiac emboli, suggested by abnormal ECGs and lack of intracerebral hemorrhage, appear to be the primary cause.
  • Identifying risk factors like hypertension and atrial fibrillation may aid in predicting and potentially preventing these events.
