Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: hepatic artery thrombosis with common hepatic duct ischemia major surgical or invasive procedure: cadaveric liver transplantation in piggyback fashion with duct-to-duct anastomosis. angiogram angiogram of hepatic artery revision of hepatic artery anastomosis (common hepatic artery of the donor to the common hepatic artery of the recipient in an end-to-end fashion), roux-en-y hepaticojejunostomy over two 5 french feeding tubes, trucut biopsy of the liver. history of present illness: mr. is a 56 y/o gentleman with esld due to hepatitic c s/p an orthotopic liver complicated by acute rejection . he presents with hepatic artery thrombosis with common hepatic duct ischemia at this time. past medical history: chronic hep c end-stage liver disease s/p orthotopic liver hepatic artery thrombosis s/p revision of anastamosis roux-en-y hepaticojejunostomy bile duct ischemia acute rejection s/p ivc filter s/p tonsillectomy s/p hernia repair social history: pt states his last alcoholic drink was in . he admits to cigar smoking. he has a distant history of iv drug abuse. family

alkphos-603* totbili-2.3* 06:25am blood afp-4.1 05:55am blood fk506-7.7 brief hospital course: the patient is a 56-year-old male who underwent an orthotopic cadaver liver on for hepatis c-related cirrhosis and hepatocellular carcinoma. on postoperative day one, the patient was noted to have an abnormal duplex ultrasound and an angiogram demonstrated a hemodynamically insignificant 40 percent stenosis of the hepatic artery. over the subsequent week, the patient had improving doppler ultrasound studies and was treated for acute allograf rejection with steroids. however, his liver function tests increased and a repeat duplex ultrasound demonstrated decreased wave form and lack of arterial flow within the hepatic parenchyma. angiography demonstrated a near-complete occlusion of the hepatic artery near the anastomosis with a small amount of clot on either side of the anastomosis, but there was still preserved flow. the patient is brought to the operating room for revision of the hepatic artery anastomosis. his postoperative course was fairly uncomplicated. he was discharged on the 30th in a good condition. medications on admission: see above discharge medications: 1.
