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: asymptomatic with aortic aneurysm major surgical or invasive procedure: endovascular stenting of ascending and aortic arch w/ debranching and re-anastomosis of right innominate and left carotid arteries history of present illness: 85 y/o male s/p thoracoabdominal aneurysm repair in . he was followed over the years with serial ct scans for known infrarenal aaa and dilated asc. aorta. recent ct scan revealed an increasing aneurysm from 6.7 to 7.8 involving the distal ascending and aortic arch. past medical history: - hypertension - aortic pathology - aneurysm ascending aorta, infrarenal aaa (3.9 x 4.5 cm), s/p thoracoabdominal aneurysm repair () - cri : recent left ureteral stone with mild hydronephrosis - prostate ca s/p radiation - diverticulosis - amputation r toe: several months ago secondary to infection - bilateral knee replacement social history: the patient currently lives alone as his wife is in rehab. he will be moving shortly to live closer to his children. he does not smoke or drink. he is a retired sales representative. family history: denies any premature cad physical exam: vs: 55 12 r155/70 l161/70 6'1" 99.8kg general: well-appearing man in nad skin: w/d and unremarkable heent: eomi, perrl, op benign neck: supple, from, -jvd, -bruits chest:

results: chest mri/mra: 1. markedly suboptimal examination due to patient and technical factors. 2. markedly attenuated and thinned right braciocephalic vein. 3. patent left brachiocephalic vein. 4. occluded left internal jugular vein. cxr: endotracheal tube is 7 cm above carina. left cordis catheter is in left jugular vein. tip of ng tube is in fundus of stomach. thoracic aortic endograft in situ. there is cardiomegaly with lv predominance and tortuosity of the thoracic aorta. there is widening of the superior mediastinum, unchanged since the prior film of . there is opacity at the left base medially obscuring the left hemidiaphragm likely due to atelectasis/consolidation in the left lower lobe and there is a probable small left pleural effusion. surgical clips are present in the left upper quadrant. no pneumothorax. head ct: there are bilateral hypodensities in the cerebellar hemispheres and bilaterally in the occipital lobes. these all to be of similar age, and are most suggestive of severe posterior circulation ischemia with infarction. the cerebellar infarcts demonstrate minimal mass effect at this time, but should be followed for later swelling and posterior fossa mass effect. there is a mass along the left optic nerve that appears focally expanded at the orbital apex. there may be a continuation of this mass in the left cavernous sinus. these findings are most suggestive of a meningioma, but other lesions, such as lymphoma, sarcoid, and optic nerve glioma, should be considered. this will be better evaluated by adding an orbital study to the brain mr. this is almost certainly a chronic finding, and need not be evaluated emergently. there is left posterior parietal and right anterior parietal and temporal scalp swelling. echo: pre-bypass: the left atrium is mildly dilated. there is moderate symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef>55%). right ventricular chamber size and free wall motion are normal. the ascending aorta is moderately dilated to 4.2 cm. the aortic arch is markedly dilated with a maximum diameter of 6.2 cm.. the descending thoracic aorta had a uniform size and texture consistent with previous descending thoracoabdominal repair by a graft. the aortic valve leaflets (3) are mildly thickened with an immobile non-coronary cusp. there is aortic sclerosis with an aortic valve area of 1.8cm2 and mild (1+) aortic regurgitation. the mitral valve leaflets are mildly thickened. there is no mitral valve prolapse. mild (1+) mitral regurgitation is seen. post-bypass: preserved biventricular systolic function. mild mr. mild ai and tr. immedialtely post bypass, there is a mobile echodensity seen in the ascending aorta and arch giving an impression of double barrel aorta with flows in both lumens. this is consistent with retrograde filling of aneurysm sac from left subclavian artery or an endoleak. the mobile echodensity represents the arch endograft placed during the surgery. at the end of the surgery, following additional stent placement, this filling resolved completely with no residual endoleak visualized. ascending and arch are difficult to visualize completely, but grafts appear grossly well seated. descending thoracic aorta is unchanged. abd/pelvis/le mra: 1. small infrarenal aaa measuring 4.2 x 3.8 cm as described above. no evidence of critical stenosis in the aorta or iliac arteries. 2. widely patent right superficial femoral to posterior tibial artery bypass. single vessel runoff to the foot through the right posterior tibial artery which supplies a widely patent dp through a collateral and diminuitive plantar arteries. 3. widely patent flow on the left to the level of the knee, where arthroplasty susceptibility obscures the popliteal artery; stenosis can not be excluded at that level. two vessel runoff with a pt and peroneal with mild irregularity; medial plantar is widely patent as is the dorsalis pedis, which is supplied from a peroneal collateral. 01:20pm blood wbc-7.1 rbc-3.99* hgb-11.5* hct-34.6* mcv-87 mch-28.8 mchc-33.3 rdw-15.9* plt ct-248 03:13am

brought to the operating room where he underwent endovascular stenting of ascending and aortic arch w/ debranching and re-anastomosis of right innominate and left carotid arteries. please see operative report for surgical details. following the surgery he was transferred to the csru for invasive monitoring in stable but serious condition. sedation was weaned off by post-op day one but patient did not wake up and had very poor response to stimuli. head ct was immediately performed and neurology was consulted. ct revealed a severe posterior circulation infarction. the consulting neurologist believed that there was a very low likelyhood of recovery of any significant neurologic function. the family initially chose to continue with aggressive treatment over the next few weeks. he has remianed in an unresponsive state, on hemodialysis, on the ventilator, and on tube feedings. due to the poor prognosis, and lack of improvement in neurologic function, the family requested that he be made a dnr, and that dialysis be stopped on . the following day, , the patient's daughter and daughter-in-law both requested for him to be extubated and made comfort measures only. a morphine drip was started for tachypnea at the time of extubation. he expired on at 1840. medications on admission: aspirin 81mg qd, norvasc 10mg qd, doxazosin, mvi discharge disposition: expired discharge
