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: back pain major surgical or invasive procedure: endovascular stent graft(l subclav->distal thoracic aneurysm) history of present illness: 83 yo m presented to lgh with 2 months of back pain, transferred to after ct scan showed aortic aneurysm from distal arch to suprarenal. past medical history: cad htn prostate ca ?cva hoh social history: family history: physical exam: vs: 97.1 65 153/69 18 (&ra general: nad w/o complaints heart: rrr, -murmur lungs: ctab -w/r/r abd: soft, nt/nd, +bs ext: warm, well-perfused pertinent results: chest cta : diffusely ectatic aorta throughout its entire course. severe dilatation between the aortic arch and level of t6 with maximal diameter of 7.6 cm and significant atherosclerotic plaque burden. aortic ectasia extends into the innominate artery and the common iliac arteries. common origin of left common carotid artery and the innominate artery. echo : there is mild symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. regional left ventricular wall motion is normal. overall left ventricular systolic function is low normal (lvef 50-55%). the right ventricular free wall is hypertrophied. the right ventricular cavity is moderately dilated. the ascending aorta is mildly dilated. there are complex (>4mm) atheroma in the aortic arch. the descending thoracic aorta is markedly dilated. there are complex (>4mm)atheroma in the descending thoracic aorta. an echogenicity consistent with large plaque/intramural thrombus was noted in the descending thoracic aorta, it measured 1.0 cm in its largest diameter. mild (1+) aortic regurgitation is seen. post endovascular stenting, an echogenic material consistent with an endostent is seen in the distal arch and descending thoracic aorta. visualization was incomplete, but no endoleak was identifited. chest cta : type iii endoleak at the level of the arch. question endoleak in the distal thoracic aorta at the level of t7. no significant changes in the maximum diameters of the aneurysmal sac. abdominal aortic ectasia and the common iliac arteries. short segment of possible dissection in the left external iliac artery. short segment of dissection in the right external artery is unchanged. 01:25am blood wbc-5.7 rbc-4.61 hgb-12.9*

mentioned in the hpi, mr. was transferred from osh after ct showed a large aortic aneurysm. upon admission he was immediately evaluated by both cardiac and vascular surgery. he underwent another chest ct upon admission. with ultimate mms reconstruction. please see pertinent results. over the next several days his blood pressure and hemodynamics were tightly managed. once mms reconstruction was completed it was determined he would undergo endograft stenting of aorta. on he was brought to the operating room where he underwent endograft stenting from his mid arch/left subclavian to his distal thoracic aorta. please see operative report for surgical details. he tolerated the procedure well and was transferred to the csru for invasive monitoring in stable condition. later on op day he was weaned from sedation, awoke neurologically intact and was extubated. lumbar drain was removed on post-op day two. he did require nitro or nicardipine secondary to hypertension several days post-op. he was then converted to oral hypertensive meds and on post-op day three he was transferred to the step-down floor. on post-op day four he had a bradycardic and hypotensive event. he did remain alert and oriented. he underwent a chest ct and then brought to the csru for closer observation. bradycardia seemed to be from second degree heart block. the next day, post-op day five, he appeared stable and was transferred back to the step-down floor. over the next couple of days he continued to look stable and good clinically. physical therapy followed him during entire post-op course for strength and mobility. he was discharged home on post-op day seven with vna services and the appropriate follow-up appointments. he will return in 2 weeks for staple removal from groin. medications on admission:
