Hyaluronic Acid Filler Injection Guided by Doppler Ultrasound

Archives of Plastic Surgery, 2023
Doppler ultrasound can be used to detect almost all arteries of the face before injecting the hyaluronic acid (HA) filler. The relatively more dangerous sites of filler injection are the glabellar wrinkle, forehead, temple, nose, and nasolabial fold area,

Diagnostic accuracy of Doppler ultrasound technique of the penile arteries in correlation to selective arteriography [PDF]

, 1988
In 63% of 265 patients with erectile dysfunction a relevant arterial inflow disturbance was found by Doppler ultrasound examination. Correlation between Doppler and arteriography in 58 patients showed an accuracy of 95% in detecting penile arteries and ...

Case Report: A Case of a Child With Facial Foreign Body Abscess and Facial Artery Pseudoaneurysm

Frontiers in Pediatrics, 2022
Facial artery pseudoaneurysms are rare and mostly a result of blunt injury. Since the facial arteries are well protected by facial soft tissue and the lumen of the facial artery is thin and small in diameter, a sharp injury usually leads to complete ...
