-
Splenic infarct. Computed tomography scan of a 51-year-old man following a motor vehicle accident. American Association for the Surgery of Trauma (AAST) grade III splenic injury, with active extravasation of contrast from the splenic parenchyma (the white area along the medial aspect of the spleen).
-
Splenic infarct. Selective splenic arteriogram showing extravasation of contrast from the splenic artery at the splenic hilum prior to angioembolization (same patient as in the above image).
-
Computed tomography scan of the spleen 5 days after angioembolization of a bleeding splenic artery, showing partial splenic infarct (demonstrated by a lack of IV contrast enhancement of the lower pole of spleen). The patient experienced no adverse sequelae and fared well following his discharge to home 5 days after the embolization (same patient as in the above images).
