Ultrasound findings in rapidly involuting congenital hemangioma (RICH) - beware of venous ectasia and venous lakes.

Abstract

Bleeding, ulceration and cardiac failure can occur in rapidly involuting congenital hemangioma (RICH). Bleeding intensity ranges from superficial to life-threatening. To determine whether there are sonographic criteria associated with an increased risk of bleeding, ulceration or cardiac failure in RICH in order to identify children who need close monitoring or prophylactic treatment. This retrospective single-center study included RICH patients over a period of 13years. We evaluated sonographic features of RICH on B-mode and Doppler ultrasound. We correlated the occurrence of bleeding, ulceration and cardiac failure with four sonographic findings: (1) visible vessel, (2) venous ectasia, (3) venous lake and (4) arteriovenous shunting. We included 24 patients. Ulceration occurred in five cases, bleeding in four cases, one of which was life-threatening. Cardiac failure was observed more frequently in RICH with venous lakes (P=0.028). Bleeding and ulceration appeared more frequently in RICH with venous ectasia and venous lakes. Cardiac failure was associated with the presence of venous ectasia. All children with cardiac failure or ulceration had arteriovenous shunts. RICH with venous lakes on ultrasound is prone to develop bleeding, cardiac failure and ulceration. This association was only significant for cardiac failure.
