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: "gas pain" not relieved by maalox major surgical or invasive procedure: thoracic graft antegrade deployment x2 from subclavian to celiac cholecystectomy history of present illness: 72 yo male with epigastric pain chronically over 2 years. had acute onset gas pain and did not resolve with meds. went to pcp and was sent to er at osh. cta revealed type b aortic dissection. transferred to on esmolol drip for surgical evaluation in stable condition. past medical history: htn "borderline" gerd anxiety social history: lives alone pipe smoker occasional etoh family history: negative physical exam: afebrile hr 67 117/71 rr 16 98% 2l nad, anxious mmm, eomi no neck masses or olad rrr with distant sounds ctab abd soft, mild mid-abd pain , no rebound warm extrems with palp. 2+ dp gossly neurologically intact pertinent results: 03:04am blood wbc-19.5* rbc-3.33* hgb-10.5* hct-31.3* mcv-94 mch-31.6 mchc-33.6 rdw-14.8 plt ct-294 02:15am blood wbc-14.4* rbc-3.78* hgb-12.4* hct-34.0* mcv-90 mch-32.7* mchc-36.3* rdw-14.4 plt ct-189 02:15am blood neuts-78.6* lymphs-14.8* monos-6.5 eos-0.1 baso-0.1 03:04am blood plt ct-294 03:04am blood pt-13.7* ptt-22.2 inr(pt)-1.2* 02:15am blood pt-12.2 ptt-19.2* inr(pt)-1.0 03:04am blood fibrino-793* 03:04am blood glucose-110* urean-24* creat-0.7 na-139 k-3.5 cl-103 hco3-25 angap-15 03:38am blood alt-61* ast-28 alkphos-125* amylase-23 totbili-0.7 03:01am blood lipase-33 03:04am blood calcium-7.5* phos-4.0 mg-2.2 brief hospital course: admitted on with above described pain and ct scan results. nipride and nicardipine drips also started in csru. he had increasing abdominal pain on hd #1 in his luq, but no chest pain as described at admission. taken urgently for torso cta. this showed extension of dissection to right iliac, with decreasing true lumen, and increasing false lumen, as well occlusion of celiac artery. please refer to fianl report. he had increasing wbc and abd pain, so he was taken urgently to the or with the cardiac and vascular surgery teams. two thoracic stent-grafts were deployed antegrade through the aorta via sternotomy (please refer to op note). cholecystectomy was also performed for gangrenous cholecystitis. on pod #1 he c/o bilat leg weakness. he had been extubated. mri showed no evidence of epidural hematoma. spinal drainage cath remained in place. neurology was consulted also. levophed was also started to help titrate up bp. some movement returned in left leg, but no movement in right leg on pod #2. chest tubes were also removed on pod #2. he required additional pulmonary toilet for poor aeration of lll and probable mucous plugging. he recovered some strength in his right leg on pod #4 and was also being treated for a uti. he remained on a nicardipine drip. lumbar drain removed on . his wbc rose to 20k on . this was thought to be possible from ? of a gangrenous spleen. bedside swallowing evaluation done on due to ? aspiration risk. at approx. 3:55 am on , the patient suffered an asystolic cardiac arrest and could not be resuscitated with acls protocols despite continuing attempts to revive him. he was pronounced expired at 4:17 am by dr. . dr. notified throughout arrest. medications on admission: zoloft prilosec discharge disposition: expired discharge diagnosis: s/p thoracic stent-grafts placed antegrade/cholecystectomy cardiac arrest htn gerd anxiety discharge condition: expired procedure: insertion of endotracheal tube other electric countershock of heart cholecystectomy transfusion of packed cells cardiopulmonary resuscitation, not otherwise specified transfusion of other serum insertion of catheter into spinal canal for infusion of therapeutic or palliative substances systemic to pulmonary artery shunt transfusion of platelets endovascular implantation of graft in thoracic aorta diagnoses: esophageal reflux tobacco use disorder urinary tract infection, site not specified atrial fibrillation other nervous system complications cardiac arrest dissection of aorta, thoracoabdominal acute vascular insufficiency of intestine acute cholecystitis laparoscopic surgical procedure converted to open procedure nonspecific abnormal results of function study of liver vascular myelopathies 

Answer: The patient is high likely exposed to
