Vascular Occlusion by Hyaluronic Acid
Quick reference guide: how to recognize a filler-induced vascular occlusion and what to do in the first hour.
Time = tissue. Every minute of ischemia increases the risk of necrosis. With ocular involvement, the window is under 90 minutes.
Vascular occlusion is the most feared complication of hyaluronic acid fillers: the material obstructs an artery or compromises blood flow, and the tissue supplied by that vessel begins to suffer ischemia. It can happen to any injector, in any area — and the first minutes define the outcome.
The right response does not depend on memory: it depends on having the protocol at hand. This guide summarizes the warning signs and first steps. The full protocol — with hyaluronidase doses, dilutions, and timers — is available free in the app.
Warning signs
- Pain disproportionate to the procedure
- Immediate or delayed skin blanching
- Pale, mottled skin or a reticular (livedoid) pattern
- Color change: white → violaceous → black
- Slowed capillary refill (more than 3 seconds)
First steps
- 1
Stop the injection immediately
At the first suspicion, do not continue. Do not massage the area aggressively and remove any compressive material.
- 2
Assess the signs and the extent
Color, pain, capillary refill, and the compromised vascular territory. Always rule out visual symptoms.
- 3
Early hyaluronidase
It is the cornerstone of treatment, and time works against you. The full protocol details doses per area, dilution, and repeat criteria.
- 4
Adjunctive measures
Local heat, gentle massage, and antiplatelet therapy as indicated by the protocol.
- 5
Document the case and decide on referral
Record times, actions, and evolution. With extensive or ocular involvement, refer to the emergency department.
This summary is for orientation. The full protocol in the app includes exact doses, dilutions, volumes per area, timers, and referral criteria — and it is free.
Visual symptoms? That is an emergency.
Vision loss, eye pain, or blurred vision immediately after injecting suggest involvement of the ophthalmic artery or its branches. The therapeutic window is under 90 minutes: activate the Post-Filler Visual Loss protocol and refer to emergency ophthalmology immediately.

Frequently asked questions
What are the first signs of a filler-induced vascular occlusion?
Pain disproportionate to the procedure, skin blanching, pale or mottled/livedoid skin, and slowed capillary refill (more than 3 seconds). A color change from white to violaceous to black indicates progression of the ischemia.
How much time do I have to act on a vascular occlusion?
The first hour is key: time = tissue. Early hyaluronidase is the cornerstone of treatment. If there is ocular involvement, the therapeutic window is under 90 minutes and requires urgent ophthalmology referral.
