Intraarterial Thrombolytic Treatment for Visual Deficits Caused by Hyaluronic Acid Filler: Efficacy, Safety, and Prognostic Factors.

Background: The benefits of intraarterial thrombolytic treatment (IATT) in reversing hyaluronic acid (HA)-related visual deficits remain unclear. This study aimed to report a 5-year experience in the treatment of visual deficits resulting from HA embolization by IATT in a tertiary medical center.
Methods: From December of 2015 to June of 2021, the medical records of consecutive patients with HA-related visual deficits who underwent IATT were reviewed retrospectively. The demographics, clinical features, imaging data, treatment details, and follow-up results of the patients were analyzed.
Results: A total of 72 consecutive patients were analyzed, including five men (6.9%) men and 67 women (3.1%), aged 29.3 ± 7.6 years (range, 17 to 50 years). Thirty-two patients (44.4%) showed preserved visual acuity, and 40 (55.6%) exhibited no light perception on admission. Ocular motility disorders were detected in 63 patients (87.5%), ptosis was detected in 61 patients (84.7%), and facial skin changes were detected in 54 patients (75%). The technical success rate of IATT was 100%, with successful recanalization of the occlusive artery. No procedure-related complications were detected, and all skin injuries, ptosis, and ocular motility disorders were healed. Improved visual acuity was detected in 26 cases (36.1%). In the binary logistic regression model, only preoperative preserved visual acuity was independently associated with a good outcome.
Conclusions: IATT for selective patients with HA-related visual deficits is efficient and safe. Preoperative preserved visual acuity was independently associated with a good outcome after IATT.
Clinical Question/level of Evidence: Therapeutic, IV.
