Summary

Perioperative cerebral infarction occurred in 16 of 615 patients undergoing cardiovascular surgery. Watershed infarction risk factors included older age and longer procedures, while embolism risks involved male sex and aortic calcification.

Area of Science:

  • Neurology
  • Cardiovascular Surgery
  • Radiology

Background:

  • Cardiopulmonary bypass is used in cardiovascular operations.
  • Perioperative cerebral infarction is a complication.

Purpose of the Study:

  • To evaluate the etiology of perioperative cerebral infarction after cardiovascular surgery.
  • To identify risk factors for watershed infarction and cerebral embolism.

Main Methods:

  • Retrospective review of 615 adult patients undergoing cardiovascular surgery from 1990-1994.
  • Neurological evaluation of pre and postoperative brain CT findings.
  • Analysis of risk factors associated with watershed infarction and cerebral embolism.

Main Results:

Related Experiment Videos

  • Sixteen patients (2.6%) suffered perioperative cerebral infarction.
  • Watershed infarction occurred in 10 patients; cerebral embolism in 6 patients.
  • Risk factors for watershed infarction: elderly, emergency surgery, longer operative and bypass times.
  • Risk factors for embolism: male sex, prior cerebral infarction, ascending aorta calcification.

    • Conclusions:

    • Watershed infarction and cerebral embolism are significant complications of cardiovascular surgery.
    • Identifying and mitigating risk factors is crucial for prevention.
    • Preventive strategies against watershed infarction are important.
