ICGA for Vascular Embolism After Hyaluronic Acid Injection

NCT07581652 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 19

Summary

Facial vascular embolism following hyaluronic acid injection is a rare but potentially serious complication that may lead to tissue ischemia, necrosis, and scarring. Early assessment of local tissue perfusion is important for evaluating treatment response and predicting clinical outcomes.

This retrospective observational study aims to evaluate whether indocyanine green angiography (ICGA) can provide objective, real-time information on tissue perfusion in patients with facial vascular embolism after hyaluronic acid injection. The study will review existing medical records, ICGA imaging data, and follow-up information from patients treated at a single center. The main question is whether ICGA findings before and after initial rescue therapy can help assess early perfusion recovery and identify patients who may require additional intervention or develop persistent tissue damage.

Conditions

  • Embolism Arterial

Interventions

OTHER

Indocyanine Green Angiography Assessment

Indocyanine green angiography was performed as part of prior routine clinical evaluation to assess local tissue perfusion in patients with facial vascular embolism following hyaluronic acid injection. In this retrospective observational study, existing ICGA imaging data obtained before and immediately after initial rescue therapy will be reviewed and analyzed. No additional ICGA examination will be performed for research purposes.
