Infected renal hematoma complicating anticoagulant therapy

Area of Science:

• Nephrology
• Hematology
• Radiology

Background:

• Anticoagulant therapy, particularly with warfarin sodium, is crucial for preventing thromboembolic events.
• Renal hematomas are a potential complication of anticoagulant therapy, though spontaneous infection is rare.
• Understanding risk factors and management strategies for infected renal hematomas is clinically significant.

Observation:

• A spontaneous infection of a renal hematoma occurred in a patient undergoing warfarin sodium anticoagulant therapy.
• The infected hematoma presented a diagnostic and therapeutic challenge.
• Ultrasound (sonar)-guided fine-needle aspiration was employed for drainage.

Findings:

• Successful drainage of the infected renal hematoma was achieved using sonar-guided fine-needle aspiration.
• This case highlights the successful management of a rare complication of warfarin therapy.
• A review of all reported cases of renal hematomas complicating anticoagulant therapy was conducted.

Implications:

• This case underscores the importance of considering infectious complications in renal hematomas, especially in patients on anticoagulation.
• Sonar-guided fine-needle aspiration is a viable and effective minimally invasive technique for managing infected renal hematomas.
• Further research into the incidence and optimal management of infected renal hematomas in anticoagulated patients is warranted.
