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: history of present illness: mr. is a 48 year old male who is status post aortobifemoral bypass grafting as well as right sided femoral to popliteal artery bypass grafting, right sided iliac stenting and aortohepatic bypass grafting with erosion of his graft into his duodenum requiring repair approximately four months ago, as well as a history of a left sided axillary femoral artery with fem- bypass grafting in , and redo of his left femoral popliteal bypass in of this year with a left sided toe amputation, who presented complaining of two days of drainage of his left groin incision and tenderness. hospital course: this was diagnosed as a wound infection and he was placed on broad-spectrum antibiotics and had wound management performed at this time. he was admitted to the floor and was doing well up until hospital day number three where he was noted to have a large amount of bloody emesis, approximately two liters, with hypotension. he was subsequently transported into the intensive care unit, had large bore intravenous access obtained, and had an esophagogastroduodenoscopy performed showing a large duodenal blood clot. he continued to require large amounts of blood and went down to angiography the next morning. in the angio suite, it was found that his axillary to femoral bypass graft was thrombosed, requiring tpa administration. he also had evidence of active bleeding requiring multiple coil embolization of multiple aortic branches. he returned to the intensive care unit following this procedure in very critically ill condition. he was maintained on high inotropic support and aggressive fluid and blood products administration. however, he went into liver failure that morning and given the poor prognosis, a discussion was carried out with the family and they felt that continuing further support was against his wishes and made the patient comfort measures only. following this, all inotropic support was removed, and the patient expired at 09:51 a.m. on . no post-mortem examination was to be performed by the family's request. discharge diagnoses: 1. massive upper gastrointestinal bleed of unknown origin. 2. thrombosed axillary femoral bypass graft. 3. sepsis. 4. multi-organ failure. 5. status post multiple vascular bypass procedures. , m.d. dictated by: medquist36 procedure: other endoscopy of small intestine injection or infusion of thrombolytic agent aortography other endovascular procedures on other vessels diagnoses: other postoperative infection acute and subacute necrosis of liver unspecified septicemia unspecified protein-calorie malnutrition surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation other complications due to other vascular device, implant, and graft chronic or unspecified duodenal ulcer with hemorrhage, without mention of obstruction aortic aneurysm of unspecified site without mention of rupture 

Answer: The patient is high likely exposed to
