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: penicillins attending: chief complaint: asymptomatic, known type b aortic dissection major surgical or invasive procedure: repair of the ascending aortic and arch aneurysm with 28 mm dacron graft (gelweave) history of present illness: mr. is a 72 year old male who developed an enteric vesiculocutaneous fistula following a prostate resection several months ago. he was found on evaluation to have a chronic type b aortic dissection, with a 6 cm ascending aortic aneurysm. chest cta in revealed an unchanged type b aortic dissection. he has a history of coronary artery disease with a prior mi back in . an echocardiogram in showed no aortic insufficiency, normal left ventricular function and only trivial mitral regurgitation. on admission, he denied chest pain, dyspnea, snyncope, abdominal symptoms, or back pain. his ostomy site is on the left and a foley catheter remains in place. the plan is for cardiac catheterization prior to cardiac surgical intervention. past medical history: ascending aortic aneurysm with chronic type b aortic dissection hypertension coronary artery disease, prior mi hypercholesterolemia bph, prostate cancer -

3.0. due to persistent confusion, he required one-on-one observation for safety. the neurology and psychiatry services were consulted, attributing his delirium to surgical/toxic/metabolic etiology rather than embolic. there was no evidence of infectious etiology. to rule out embolic etiology, a head ct scan was obtained which found no evidence of infarction or hemorrhage. the renal service was concomitantly consulted to assist in the management of his persistent hyponatremia. with fluid restriction and salt supplementation, his hyponatremia slowly improved. unfortunately, postoperative delirium continued to persist. he was seen by occupational therapy who felt that he was safe to go home with supervision. case management spoke with his family who felt that he has experienced post op delerium in the past and that he improved with discharge home, they also relayed that he would have supervision, that his wife is competent and that she has a nurse who visits the house for her medical issues. medications on admission: aspirin 81 qd, atenolol 50 qd, lipitor 20 qd, zantac 150 , lisinopril 5 qd, lasix 20 qd, norvasc 10 qd discharge medications: 1. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*0* 2. atorvastatin 20 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*0* 3. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*30 capsule(s)* refills:*0* 4. multivitamin capsule sig: one (1) cap po daily (daily). disp:*30 tabs* refills:*0* 5. thiamine hcl 100 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 6. coumadin 1 mg tablet sig: one (1) tablet po once a day: adjust dose based on inr value. disp:*30 tablet(s)* refills:*2* 7. erythromycin 5 mg/g ointment sig: one (1) ophthalmic tid (3 times a day) for 5 days. disp:*qs 5 days* refills:*0* 8. protonix 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po once a day. disp:*30 tablet, delayed release (e.c.)(s)* refills:*0* discharge disposition: home with service facility: north country home care discharge diagnosis: chronic type b aortic dissection and ascending aortic aneurysm -
