Abstract

IMPORTANCE: Pseudoaneurysm is a well-known complication of trauma and iatrogenic injury to the vasculature.We report 3 cases of postsurgical pseudoaneurysm after Mohs surgery. OBSERVATIONS: Three patients who underwent Mohs surgery for nonmelanoma skin cancers presented between 2 and 4 weeks after surgery with several days' history of painful, enlarging, pulsatile subcutaneous masses. The lesions were diagnosed as postsurgical pseudoaneurysm. During surgical repair of each lesion, we identified vascular outpouchings that were connected to the injured arteries by sinus tracts. In all 3 patients, we ligated the affected artery and the neck of each lesion and reapproximated the skin. All wounds healed well without further recurrence. CONCLUSIONS AND RELEVANCE: Most reported cases of pseudoaneurysm formation in the head and neck involve the superficial temporal artery and its branches, and they typically occur secondary to blunt force trauma. Our cases are unique in that they included 1 case of a superficial temporal lesion but also 2 cases outside this system: 1 of the lateral nasal artery and 1 of the angular artery.We propose operative repair as the treatment of choice for facial pseudoaneurysms that complicate dermatologic surgery.
