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: acute exacerbation of right lower quadrant abdominal pain s/p l hepatic lobectomy major surgical or invasive procedure: ex lap, small bowel resection, jejunojejunostomy history of present illness: mr. is a 65-year-old male with cirrhosis and recently underwent a left hepatic lobectomy secondary to a segmental caroli disease. his postoperative course was uneventful. he returned to the emergency room on the afternoon of with abdominal pain and not feeling well. he underwent workup in the emergency room to include a ct scan, which demonstrated what appeared to be portal and smv thrombus. delayed images on the venous phase were not obtained on this ct scan and he went down for a subsequent ct scan that confirmed the presence of smv and portal venous thrombosis. at this time, with a normal white count, now nonacidotic and no significant abdominal discomfort or peritonitis, he was treated with anticoagulation. over the evening of and the early morning of , he became more tachycardic and his white count increased to 14,000. on examination he began experiencing some abdominal discomfort. based upon the clinical picture and the examination and our suspicion for mesenteric ischemia, he was taken to the operating room for exploration. past medical history: s/p liver lobectomy caroli's disease hemochromatosis social history: lives with wife 3 children family history: mother died of metastatic colon cancer at age 61 father died of cardiac disease at age 56 one brother with colonic polyps and hypertension physical exam: on admission: vs: 96.1, 106, 152/95, 18, 97% ra gen: appears uncomfortable, skin color/temp wnl lungs: cta bilaterally card: reg rhythm, sl tachy abd:

brief hospital course: patient admitted with increasing abdominal pain. u/s showed a portal vein thrombosis. ct of abdomen revealed findings consistent with extensive portal venous and superior mesenteric venous thrombosis with a long segment of markedly abnormal jejunum, highly concerning for bowel ischemia. there was also a small amount of ascites. patient taken to the or for exploratory laparotomy, small bowel resection and jejunojejunostomy. 40 cm of the jejunum was resected. postoperatively the patient did well. he was admitted to the sicu and placed on a heparin gtt. due to patient history of varices and cirrhosis, heparin was initially d/c'd, however it was restarted with monitoring, hct's stable, no events. goal ptt 50-70. metronidazole and cefazolin were started for prophylaxis. lactate dropped to normal range. -rheumatology consulted to evaluate for vasculitis which was seen on the preliminary biopsy of the small bowel: "extensive acute necrotizing vasculitis involving both arteries and veins. the vasculitic changes appear to be primary rather than secondary. systemic vasculitic syndromes should be considered" rheum recommended multiple tests as well as mra/mrv to assess for further evidence of vasculitis. mra showed thrombosis of the portal and superior mesenteric veins. overall, the appearance is similar to the ct angiogram and persistent small bowel wall thickening and edema. -coumadin was started on pod 3 with heparin bridge and patient will be discharged on anticoagulation. hem-onc recommends anticoagulation with coumadin for at least 6 months given acute, potentially life-threatening thrombotic event. -patient began taking po's, but nutritional status was in question due to poor po intake. n-j tube was placed and the plan was to start cycled tube feed which would be continued at home. home teaching was provided by . -left upper arm u/s was completed on for antecubital swelling, warmth and discomfort. reported acute venous thrombosis within the basilic vein extending from the antecubital fossa more proximally to the mid upper arm. other examined veins were grossly patent. as patient already anticoagulated with coumadin, no further action at this time. -on in the early evening during rounds, it was decided to send patient home. he would start tube feeds on friday, coumadin to be held for inr 4.1. on friday the patient was to proceed to outpatient for recheck of pt/inr and coumadin recommendations for the weekend. he will then be having pt/inr drawn mon/thurs with results sent to clinic. follow up visits with surgery and rheum. patient will also be having follow up visit with pcp once surgical issues/healing are resolved. medications on admission: dilaudid 3 mg qd colace pepcid mvi discharge medications:
