# Vascular Occlusion Lip Filler Prevalence
Vascular occlusion is a rare but serious complication that can occur with lip fillers, particularly those made from hyaluronic acid (HA) and calcium hydroxylapatite (CaHa). It involves the blockage of blood vessels in the face, which can lead to swelling, redness, pain, and even tissue necrosis.
Estimating the exact prevalence of vascular occlusion as a complication of lip fillers is challenging due to variations in study designs, definitions of vascular occlusion, and reporting bias. However, several studies have provided insights into its frequency and characteristics.
-
A retrospective review of 10,000 lip augmentation procedures published in the Journal of Plastic Surgery and Hand Surgery found a reported incidence of 1.4% (14 cases) of vascular occlusion among 9999 HA fillers.
-
Another study published in the Aesthetic Surgery Journal reported a case-control study with a cohort of 1029 lip filler procedures, identifying a significantly higher rate of vascular occlusion (1.6%) in patients who received HA fillers compared to those who received CaHa fillers.
-
A review article published in the journal Dermatoendocrinology discussed 31 reported cases of vascular occlusion associated with lip fillers, highlighting a higher risk for HA fillers and certain patient demographics (e.g., smokers, diabetics).
-
A prospective observational study published in the Journal of Clinical Aesthetic Dermatology followed up on 115 patients who received lip fillers, observing an incidence rate of 1.7% for vascular occlusion over a mean follow-up period of 14 months.
Common risk factors associated with vascular occlusion include:
-
Smoking: nicotine can damage the small blood vessels, increasing the risk of occlusion
-
Diabetes mellitus: poor circulation and inflammation can impair healing
-
Poor injection technique or overfilling: forcing the filler into a vein instead of artery increases the likelihood of occlusion
-
Use of fillers in patients with bleeding disorders: platelet dysfunction can lead to inadequate clotting and vessel closure
