Clinical Scorecard: Laceration of the profunda femoris vein due to a displaced lesser trochanter fragment: an intraoperative vascular complication in intertrochanteric fracture management

At a Glance

Key Highlights

• Vascular injury in intertrochanteric fractures is rare, predominantly arterial; venous injury is exceptionally uncommon.
• Preoperative CT can reveal sharp lesser trochanter fragments in close proximity to major vessels even when Doppler ultrasound is negative.
• Intraoperative exploration and repair of venous injury with resection of offending fragment can prevent catastrophic hemorrhage.

Guideline-Based Recommendations

Diagnosis

• Perform detailed preoperative imaging including CT to assess anatomical relationship of fracture fragments to vascular structures.
• Use Doppler ultrasound to evaluate vascular flow but recognize its limitations in detecting vessel wall injury or adherence.
• Consider intraoperative vascular exploration when high-risk anatomy is identified despite negative noninvasive vascular studies.

Management

• Prioritize securing vascular safety by exploring and repairing any venous injury before fracture fixation.
• Resect displaced lesser trochanteric fragments that pose risk to adjacent vessels.
• Use intramedullary nailing for fracture fixation after vascular repair.

Monitoring & Follow-up

• Monitor hemoglobin levels serially to detect occult bleeding.
• Postoperative surveillance for deep vein thrombosis is essential, especially after venous injury and repair.
• Manage thrombotic complications with anticoagulation and consider inferior vena cava filter placement if indicated.

Risks

• Intraoperative venous laceration leading to hemorrhage.
• Postoperative deep vein thrombosis following venous injury and repair.
• Diagnostic challenges due to negative Doppler ultrasound despite high-risk anatomy.

Patient & Prescribing Data

Elderly patients with intertrochanteric fractures and displaced lesser trochanter fragments

Anticoagulation and inferior vena cava filter may be required postoperatively to manage deep vein thrombosis following venous injury repair.

Clinical Best Practices

• Thorough preoperative imaging review to identify displaced bony fragments in proximity to major vessels.
• Do not rely solely on Doppler ultrasound to exclude vascular injury when CT shows high-risk anatomy.
• Plan for intraoperative vascular exploration and repair prior to fracture fixation in cases with suspected vascular risk.
• Resect sharp bony fragments that threaten vascular structures to prevent intraoperative injury.
• Implement postoperative monitoring and prophylaxis for venous thromboembolism after venous injury.
