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: past medical history is the subarachnoid hemorrhage status post coiling, hypertension and history of drug abuse. past surgical history is hysterectomy. admission medications are hydrochlorothiazide and oxycodone. allergies are to codeine-itching. on she underwent a cerebral angiogram for coiling of the left fetal pca origin residual aneurysm. a coil was placed in the aneurysm then after placement of a second coil, the latter was noted to migrate into the left fetal pca and occlude flow in that branch. an effort at retrieving the coil was unsuccessful because of the tortuosity of the fetal pca proximal segment. the coil was left in place and the patient awaken from anesthesia. she was not noted to have any changes in her vision. no double vision or loss of vision was reported prior to the procedure. at the completion of the procedure her vision was intact, visual fields were grossly intact, she was moving all extremities well. she was alert and oriented without any neurological deficits. she was transferred to the post anesthesia care unit where she remained for the next two days. during her stay in the post anesthesia care unit, neurologically she remained unchanged. she denied any changes in her visual fields. her only complaint was for a headache. she reports that it was the same intensity as preoperatively. she denied any nausea or vomiting with these headaches. there was no change in her mentation. she was transferred to the floor and she has remained neurologically unchanged. vital signs have been stable. she has been afebrile. she was placed on a heparin drip for 24 hours with a goal ptt of 50 to 60. she was started on plavix as well as to continue with her aspirin q. day. on she was transferred to the floor. she has remained neurologically stable. her heparin was discontinued. she has continued on her aspirin and plavix. she has been out of bed, ambulating in the halls without difficulties. her neurological examination has remained unchanged. she is scheduled for discharge on . assessment: a 40 year old female status post cerebral angiogram for coiling of recurrently regrowing previously clipped left pca origin aneurysm, complicated by a coil migration into and occlusion of the left pca. she tolerated the procedure despite the occlusion of the vessel without neurological deficit. she is slated for close follow-up in 1 month to rule out residual regrowth of a small pocket of contrast filling at the origin of the left pca. plan: 1. discharge on . 2. she is to follow up with dr. in one month. 3. monitor the groin site for any signs of drainage, redness or fever, and for any neurological symptoms including headache, weakness, numbess, she is to call dr. office or return to the emergency department. discharge medications: 1. hydrochlorothiazide 25 mg p.o. q. day 2. percocet 5/325 one to two tablets p.o. q. 4-6 hours prn as needed. 3. acetaminophen 325 1 to 2 tablets p.o. q. 4-6 hours prn as needed. 4. docusate sodium 100 mg one p.o. b.i.d. 5. aspirin 325 mg p.o. q. day. 6. nicotine patch 21 mg/24 hour one p.o. q. day. 7. famotidine 20 mg tablets, one p.o. b.i.d. 8. plavix 75 mg one p.o. q. day. , m.d. dictated by: medquist36 procedure: arteriography of cerebral arteries arterial catheterization endovascular (total) embolization or occlusion of head and neck vessels diagnoses: unspecified essential hypertension cerebral aneurysm, nonruptured other specified surgical operations and procedures causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation mechanical complication of nervous system device, implant, and graft 

Answer: The patient is high likely exposed to
