How safe is thromboprophylaxis in abdominoplasty?

Area of Science:

• Plastic Surgery
• Vascular Surgery
• Pharmacology

Background:

• Deep vein thrombosis (DVT) and pulmonary embolism (PE) are significant risks in hospitalized patients.
• Abdominoplasty is frequently linked to DVT in plastic surgery.
• Venous thromboembolism (VTE) prophylaxis is crucial for high-risk patients.

Purpose of the Study:

• To evaluate the efficacy and safety of oral rivaroxaban for VTE prevention post-abdominoplasty.
• To assess the risk-benefit profile of VTE prophylaxis in this patient group.

Main Methods:

• A randomized, double-blind, placebo-controlled study.
• 40 patients undergoing abdominoplasty were randomized.
• Intervention: Oral rivaroxaban (10 mg) or placebo daily for 10 days, initiated 6-8 hours post-surgery.

Main Results:

• Study halted prematurely after 27 operations due to systematic complications.
• All observed complications (29.6% overall rate, large hematomas requiring drainage) occurred in the rivaroxaban group.
• No complications were reported in the placebo (control) group.

Conclusions:

• Plastic surgery involving extensive tissue detachment in moderate-risk patients requires careful risk-benefit assessment for VTE prophylaxis.
• Alternative preventative measures should be considered, potentially contraindicating surgery.
• Further research is necessary to validate these findings and guide clinical practice.
