Spontaneous intercostal artery bleeding is a rare disease seen in cirrhosis and can present with hemodynamically significant blood loss anemia, hypotension, and shock. Transcatheter arterial embolization is an effective treatment for severe cases.

1. CASE PRESENTATION
A 44‐year‐old male with alcoholic cirrhosis presented with one day of fatigue. He noticed a painful bruise over his body's left side but denied any trauma or falls. On arrival, he was hypotensive with a hemoglobin of 2.7 g/dl, platelet count of 46,000/mm3, and INR of 2.04. Computed tomography of the chest and abdomen revealed a large intramuscular hematoma within the left lateral chest wall extending to the upper abdomen measuring 12 cm × 5 cm and several foci of high attenuation suggestive of acute hemorrhage (Figures 1 and 2). The patient was aggressively resuscitated with our institution's massive transfusion protocol, including four units of red blood cells, four units of fresh frozen plasma (FFP), and one apheresis unit of platelets. Interventional radiology was consulted, and emergent angiography was performed. Active extravasation from the left ninth intercostal artery was noted. Successful embolization with 500‐ to 700‐micron embospheres followed by gel foam slurry was performed (Figures 3 and 4). Spontaneous intercostal artery bleeding is rare in cirrhosis, with few cases reported so far.1 Risk factors, in addition to thrombocytopenia and clotting factor deficiency in cirrhotic patients, are alcohol use, trauma, hypertension, and anticoagulation.2 Management of closed space spontaneous bleeding in cirrhotic patients is challenging. In mild cases, medical management with judicious use of blood products should suffice. Severe cases are managed with transcatheter arterial embolization and, ultimately, liver transplantation.
