On examination, the lateral compartment of the leg was swollen, ecchymotic, and tense [Figure 1]. A Doppler ultrasound evaluation revealed a large intramuscular hematoma in the lateral compartment of the leg, with a PA of a muscular branch of the anterior tibial artery [Figure 2 and Video 1].

A Doppler ultrasound evaluation revealed a large intramuscular hematoma in the lateral compartment of the leg, with a PA of a muscular branch of the anterior tibial artery [Figure 2 and Video 1]. Under ultrasound guidance, 0.5 ml of thrombin was injected into the PA with successful thrombosis of the sac [Figure 4 and Videos 2 and 3].

He was subsequently taken up for thrombin injection into the PA [Figure 3]. Under ultrasound guidance, 0.5 ml of thrombin was injected into the PA with successful thrombosis of the sac [Figure 4 and Videos 2 and 3].
