A New Study Finds Peri-procedural Thromboembolic Events Rare in Patients With Venous Malformations

December 2, 2020

UPMC Division of Pediatric Otolaryngology and Department of Otolaryngology faculty members recently published their research on periprocedural anticoagulation for venous malformations (VM) and the associated risk of thromboembolic and disseminated intravascular coagulation (DIC) events in Laryngoscope.

The research team compared the risk of thromboembolic and DIC events post-procedure in head and neck and extremity VM patients through an IRB-approved, retrospective chart review on 120 patients.

They found that post-procedure thromboembolism is rare in the treatment of VM, particularly in the head and neck. This study found zero thromboembolic events in the head and neck group, regardless of anticoagulation use. With a small sample size, the odds of such events are rare and may approach zero.
