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: this is a 54 year old male with known peripheral vascular disease who underwent a right fem- popliteal bypass graft in , now here complaining of significant leg pain times two weeks, now with increasing intensity which is describes as a . he also has noted onset of coolness of the foot and mottling of the skin today. the patient had been on plavix which he discontinued two months ago. patient was initially evaluated in the emergency room and he was begun on intravenous heparin at a bolus of 6200 units and infusion started at 1400 units per hour with monitoring of coags. morphine sulfate was administered to the patient for analgesic control. the patient was seen by the vascular service in the emergency room. patient was prepared for emergent arteriogram with possible surgical exploration. past medical history: is significant for tobacco use and peripheral vascular disease, hypertension. past surgical history: as indicated in the history of present illness. the bypass graft that was done was a ptfe. the patient has had an open cholecystectomy and a dupuytren contracture repair. he denies any drug allergies. medications on admission: lopressor 25 mg b.i.d, aspirin which he does not take on a regular basis and plavix 75 mg daily which he stopped several weeks ago. social history: denies alcohol use but has excessive tobacco use. physical examination: vital signs: 98.2, 80, 174/80, 16, 97 percent oxygen saturation on room air. general appearance: alert male with moderate distress. heent examination was unremarkable. lungs were clear to auscultation bilaterally. heart was regular rate and rhythm. abdominal examination was benign. extremity examination showed left lower extremity was warm with palpable pulses and 1 plus ankle edema. the right lower extremity was with erythema to the knee, was cool with 2 plus edema with diminished sensation and weak flexion extension of the ankle and toes. the pulse examination shows palpable radial pulses bilaterally 2 plus, femoral pulses on the right were 1 plus and distal to the right femoral artery pulse all remaining extremity pulses on the right side were absent. on the left his popliteal, posterior tibial and dorsalis pedis pulses were palpable 2 plus. hospital course: the night of admission the patient underwent a retrograde left common femoral artery access and had an angiojet of the right femoral- graft, followed by angioplasty of the proximal and distal anastomosis and angioplasty of the popliteal artery. infusion of 2 mg of tpa and placement of a thrombolysis infusion catheter into the right fem- graft was done at the end of the procedure. the findings were normal aorta and iliacs. the common femoral was occluded. there is a patent profunda femoris. the graft was occluded. there was thrombus and plaque in the popliteal and peroneal arteries with a stenosis of greater than 50 percent present in the mid popliteal artery. the anterior tibial and posterior tibial were occluded. there was a reconstitution of the posterior tibial artery distally. the peroneal was the main run-off vessel to the foot. stenosis was present and moderately severe at the distal anastomosis. the patient tolerated the procedure well, was continued on tpa infusion and was transferred to the surgical intensive care unit for continued monitoring and care. the patient remained hemodynamically stable. aspirin and plavix were started on . intravenous heparinization with tpa was continued for a goal ptt of 60 to 80. regular vascular checks were continued and his coagulations and hematocrits were monitored and fibrinogen levels were monitored q 4 hours. adjustments in tpa and heparin were made at that time. the patient did well overnight and returned to the angio suite on . at that time he underwent a right leg run- off with angioplasty of the knee, popliteal and distal anastomosis of the fem-ak- graft and profunda femoris. there was an angioplasty of the native posterior tibial with rheolytic angiojet thrombectomy of the right profunda femoris artery. the femoral artery was closed with perclose. patient tolerated the procedure and returned to the vascular intensive care unit for continued monitoring and care. patient had required intravenous nitroglycerin during the angio procedure for systolic hypertension. this was weaned off by the time he was transferred to the vascular intensive care unit. the examination showed a groin with serosanguineous drainage but no hematoma and the right foot was warm. extremity was warm and there was a biphasic dp signal and a monophasic pt signal. patient did have some st changes during the procedure. he was treated with nitroglycerin and lopressor and electrocardiogram was examined. there were no ischemic changes noted. serial enzymes times one were obtained. post angio total cpk was 4100. the mb and troponin levels were flat. the patient did well overnight in the vascular intensive care unit. he remained hemodynamically stable. his examination remained unchanged. there was no groin hematoma. the st changes resolved with the lopressor. he was continued on lopressor, aspirin and plavix. coumadinization of 7.5 mg at bedtime was instituted. intravenous heparinization was continued during the conversion period. his foley was discontinued. the patient was transferred to the regular nursing floor on . hospital course otherwise was unremarkable except for some mental status changes which occurred on hospital day number 4. psychiatry was consulted. they felt that the mental status changes were secondary to delirium which was multifactorial in etiology. the patient underwent a chest x-ray which was unremarkable for acute pulmonary process or infiltrates. a head ct was done which was negative for any intracranial bleed or mass. the patient was continued on haldol for agitation. his narcotics were minimized as necessary and he was begun on vitamin b12. over the next 48 hours his mental status improved. by hospital day nine patient remained without complaint but was very much interested in returning to rehabilitation for continued therapy. the remaining hospital course was unremarkable. the patient's heparin was discontinued on . the patient's inr was greater than 2.0 and therapeutic. discharge planning was instituted. at the time of discharge the patient was stable. mental status was cleared. vascular examination was with a warm foot with a triphasic dp and pt bilaterally. discharge diagnoses: 1. ischemia of the right extremity secondary to graft occlusion secondary to thrombus status post thrombectomy angioplasty and tpa. 2. post procedure delirium, resolved. 3. history of alcohol use. 4. history of nicotine abuse. patient was placed on nicotine patch. discharge medications: 1. plavix 75 mg daily. 2. aspirin 325 mg daily. 3. nicotine 14 mg patch q 24 hours. patient to follow up with the primary care physician regarding continuation of smoking cessation program. 4. metoprolol 75 mg q.i.d. 5. oxycodone/acetaminophen 5/325 tablets one to two q 4 to 6 hours prn for pain. 6. vitamin b12 100 mcg daily. 7. pentamidine 20 mg tablets b.i.d 8. coumadin 75 mg at bed time. inr should be monitored at least twice a week. the goal inr is 2.0 to 3.0. these results should be called to dr. office. , m.d.
