Combined nephrectomy and aortic valve replacement: perioperative decision-making.

Area of Science:

• Cardiology
• Urology
• Anesthesiology

Background:

• Coincident diseases requiring both cardiac and urologic surgery present complex management challenges.
• A patient with asymptomatic aortic valve stenosis and atrial fibrillation developed a perinephric hematoma while on warfarin therapy.

Observation:

• The primary challenge was determining the optimal timing for aortic valve replacement in the presence of a bleeding perinephric hematoma.
• Standard guidelines suggest addressing severe cardiac disease first, but this was contraindicated due to the risk of increased bleeding with heparinization for cardiopulmonary bypass.

Findings:

• The case required a multidisciplinary approach to perioperative decision-making, balancing risks of cardiac and urologic interventions.
• The patient's perinephric hematoma complicated the traditional approach to managing severe cardiac disease before elective noncardiac surgery.

Implications:

• This case underscores the need for individualized perioperative strategies in patients with multiple comorbidities.
• Re-evaluation of existing guidelines for managing patients with concurrent cardiac and urologic conditions requiring surgery is warranted.
