Abstract
BACKGROUND: Compromised blood flow after filler injection is generally thought to result from intra-arterial obstruction. AIMS: To test this hypothesis. PATIENT: A case presented with the clinical picture of reduced arterial blood flow after hyaluronic acid filler injection in the temporal region and subsequent hair loss. METHOD: Clinical and ultrasound (US) assessments as well as ultrasound guided hyaluronidase injection were performed. RESULT: Blood flow was restored and hair loss proved to be temporary. CONCLUSION: There are many arguments to conclude that the problem did not result from intra-arterial occlusion, but rather from outside compression of the artery.
