Factor V Leiden and perioperative risk.

Area of Science:

• Medical Genetics
• Hematology
• Surgical Risk Assessment

Background:

• Factor V Leiden (FVL) is the most prevalent inherited thrombophilia, affecting ~5% of Caucasians.
• Perioperative thrombotic and hemorrhagic risks associated with FVL are not well-established.
• Limited research exists on FVL's impact in the surgical population, necessitating comprehensive review.

Purpose of the Study:

• To review the physiology of the Factor V Leiden mutation.
• To summarize FVL's risk in non-surgical contexts.
• To assess current data on FVL in cardiac and noncardiac surgery.

Main Methods:

• Literature review and synthesis of existing studies.
• Analysis of physiological mechanisms of FVL.
• Evaluation of clinical data on FVL in surgical patients.

Main Results:

• FVL is a significant inherited risk factor for venous thrombosis.
• Existing data on perioperative FVL risk is limited but growing.
• Further investigation is needed to fully understand FVL's role in surgical complications.

Conclusions:

• Factor V Leiden poses a potential, yet understudied, perioperative risk.
• Comprehensive investigation into FVL's impact on surgical outcomes is warranted.
• Evidence-based guidelines are needed for managing FVL in surgical patients.
