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: the patient is a 73-year-old male with four days of history of right upper quadrant pain. he denied nausea or vomiting. the pain was worse with eating. there was no change in bowel activity. he also reported positive pain in the right calf after walking a couple of miles, also in the right buttock and right thigh area. comorbidities include hypercholesterolemia, questionable diabetes, status post back surgery, and hypertension. physical examination: the patient was afebrile, pulse 55, blood pressure 199/87, breathing at a rate of 16, 98% oxygen saturation on room air. the patient was a tanned portly man in no apparent distress. heart rate was regular. lungs were clear to auscultation bilaterally. abdomen was round with right upper quadrant and right midabdominal tenderness. carotid examination revealed no bruits. there was no pulsatile mass in the abdomen. all lower extremity pulses were 2+ including femoral, popliteal, dorsalis pedis and posterior tibial pulses bilaterally. the patient was noted to have a small umbilical hernia, no inguinal hernias noted. on rectal examination no masses were palpated. the patient was guaiac negative. laboratory data: on admission the laboratory studies were all within normal limits. ekg revealed normal sinus rhythm. ct of the abdomen showed a 4.5 cm right iliac artery aneurysm without extravasation. left common iliac was 2.7 cm. hospital course: post admission the patient received regular preoperative work-up including appropriate laboratory studies, chest x-ray, ekg, and in addition the patient received cardiology clearance, as well as a right upper quadrant ultrasound to rule out cholelithiasis and cholecystitis. after a positive stress test the patient received cardiac catheterization on . upon pulling out of the sheath post cardiac catheterization, the patient experienced a vagal episode where his heart rate dropped to the 30s and blood pressure to systolic of 59. the patient received two amps of atropine as well as dopamine started at 20 cc per hour. blood pressure increased to 111/63. the patient was also fluid resuscitated with three liters of normal saline. cardiac catheterization analysis revealed a mild two-vessel coronary artery disease as well as a mild left ventricular systolic and diastolic dysfunction. ejection fraction was 51%. once the patient received clearance for the operating room, the patient was taken for aortobifemoral bypass on . for a detailed account of surgery, please see the operative report. postoperatively the patient experienced abdominal distention as well as abdominal discomfort. kub obtained on postoperative day number five revealed dilated loops of bowel, both small intestine and colon, positive air in the rectum. the picture was consistent with postoperative ileus as opposed to obstruction of some sort. the patient at that time received nasogastric tube put to low continuous wall suction with good results. distention went down as well as the patient's discomfort. repeat kub on revealed resolution of dilated loops. the patient was started on tpn on due to prolonged course of n.p.o. in the early am of the patient's nasogastric tube was discontinued with no resulting nausea, vomiting, or distention. the patient was started on a regular diet on starting with clears in the am, general diet in the evening. on the patient's staples were discontinued. steri-strips were applied. the patient is stable on discharge. discharge status: to home. discharge diagnoses: right iliac artery aneurysm status post aortobifemoral bypass. discharge medications: 1. metamucil. 2. lipitor 40 mg p.o. q. day. 3. aspirin 81 mg p.o. q. day. 4. clorazepate 7.5 mg p.o. q. day. 5. atenolol 50 mg p.o. q. day. 6. tricor 160 mg p.o. q. day. 7. verapamil 240 mg p.o. q. day. 8. ultram p.r.n. follow-up plans: the patient will follow up with dr. in vascular surgery clinic at in one to two weeks. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified parenteral infusion of concentrated nutritional substances angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter resection of vessel with replacement, abdominal arteries diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension other and unspecified angina pectoris paralytic ileus aneurysm of iliac artery umbilical hernia without mention of obstruction or gangrene 

Answer: The patient is high likely exposed to
