"Vascular occlusion aft filler injections tin pb to devastating outcomes, including tegument necrosis, insubstantial loss, and — successful the worst cases — blindness and adjacent stroke," Dr. Anthony Berlet, a board-certified integrative surgeon successful New Jersey, who was not progressive successful the research, told Fox News Digital. 

"Once a captious artery — for example, 1 feeding the retina oregon tegument — is occluded by filler oregon embolus, the harm whitethorn beryllium irreversible."

Ultrasound helped doctors pinpoint the locations of the blockages, allowing them to spot a dissolving enzyme (hyaluronidase) close wherever it was needed and debar utilizing large, guesswork doses.

The researchers suggested that utilizing ultrasound during the injection itself could assistance to forestall blood-vessel injuries and alteration faster, much precise attraction if blockages occur.
