Vascular Occlusion
Blockage of a blood vessel by an injected substance, most critically a rare but potentially catastrophic complication of dermal filler injection that can result in tissue necrosis or vision loss.
Full Definition
Vascular occlusion in cosmetic dermatology refers to the inadvertent injection of filler material into or adjacent to a blood vessel, causing partial or complete blockage of arterial or venous flow. The sequelae range from localised skin necrosis to blindness if the ophthalmic artery is affected, making this the most feared acute complication in injectable aesthetics. Editors working on treatment protocols, consent forms, and complication management guidelines must ensure the term is used precisely and not minimized. The correct term is 'vascular occlusion', not 'vascular event' or 'vascular issue', which dilute the severity. Hyaluronidase is the standard emergency dissolving agent referenced in management sections.
Usage
Usage note: Never soften to 'vascular event' or 'vessel issue' in clinical or consent documents. Severity must be clearly communicated. Always verify hyaluronidase emergency protocol is referenced in injectable guidelines.
In Context
- "The consent form listed vascular occlusion as a rare but serious risk of periorbital filler injection, including the possibility of permanent vision loss." — Patient consent form
- "Editors must not substitute 'vascular complication' for 'vascular occlusion' in safety documentation, as the latter term carries specific clinical meaning." — Regulatory document editing guide
