Cosmetic injections, such as dermal fillers, are an increasingly popular option for facial rejuvenation, but carry potential risks that patients should be aware of. A new study presented this week highlights the possibility of serious complications, including vascular occlusion-blockages of major blood vessels-following hyaluronic acid filler injections. Researchers have found that readily available ultrasound technology can now aid in the early detection of these blockages, perhaps minimizing permanent damage and improving patient outcomes. The study, analyzing data from over 100 patients between May 2022 and April 2025, underscores the importance of both qualified practitioners and advanced diagnostic tools in ensuring patient safety.
Cosmetic injections, commonly known as fillers, can potentially cause blockages in major blood vessels, leading to serious health complications, experts warn. The risk, while generally low with qualified practitioners, highlights the growing need for advanced detection methods.
A study presented this week at the annual meeting of the Radiological Society of North America in Chicago found that ultrasound technology can detect these dangerous blockages early enough to guide treatment and potentially prevent permanent damage. Researchers analyzed data from 100 patients across six different locations who experienced vascular complications following hyaluronic acid filler injections. All data was collected between May 2022 and April 2025.
The study confirmed that ultrasound effectively identified vascular occlusion – a blockage in a blood vessel that disrupts normal blood flow. If left untreated, this condition can cause pain, skin damage, and scarring. In severe cases, complications can escalate to vision loss or stroke.
“Doppler ultrasound helps doctors see exactly where the filler is, how blood is flowing in real time, and whether blood vessels have been affected after a cosmetic procedure,” explained Dr. Rosa Maria Silva Seigrist, the lead researcher. “While a physical exam remains very important, ultrasound adds extra information that makes the assessment safer and the treatment more precise.”
The nose is identified as a particularly vulnerable area due to the proximity of the lateral nasal artery, which supplies blood to larger arteries leading to the eye and brain.
“Vascular occlusion after filler injections can lead to devastating outcomes, including skin necrosis, tissue loss, and, in the worst cases, blindness and even stroke,” said Dr. Anthony Bared, a board-certified plastic surgeon in New Jersey. “Once a critical artery – for example, one that feeds the retina or the skin – is blocked by filler or a blood clot, the damage can be irreversible.”
The risk of vascular occlusion is generally less than 1% when performed by a qualified and licensed specialist using appropriate techniques, according to Dr. Samuel Golbanyian, a board-certified plastic surgeon in Beverly Hills. “However, if fillers are administered by someone untrained or using incorrect needles or methods, the rate of complications can be much higher, ranging from 10% to 20%, which is completely unacceptable,” he added.
