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: history of present illness: the patient is a 59-year-old gentleman who had a past medical history of hypertension and had a shubarachnoid hemorrhage from a ruptured basilar tip aneurysm which was treated using coil embolization in . he now returns for follow-up study given its wide neck anatomy. his hedaaches have since resolved. brief summary of hospital course: the patient underwent angiography which showed recanalization and compaction of the coil mass. the aneurysm residual has a wide neck and cannot be treated without resorting to stent-assist technique. accordingly the patient underwent neuroform stent placement in both origins aof the pca vessels. no coils were placed during this procedure to enable the endothelial coverage and incorporation of the stent into the vessel wall prior to additional manipulation. the patient had a brief episode of diplopia on . an angiogram was repeated which was negative for any signs of vasospasm, stroke, or emboli. the patient had no further episodes of diplopia and had no complaints of a headache throughout the rest of his stay in the hospital. the patient was continued on aspirin 325 mg by mouth once per day and plavix 75 mg by mouth once per day, status post procedure. the femoral sheath was discontinued on in the evening with no sign of hematoma. the patient was out of bed on and ambulated without difficulty. the patient was neurologically intact. extraocular movements were intact. the smile was symmetric, and there were no signs of drift status post the procedure. the patient's laboratories remained stable, and the patient vital signs also remained stable, and the patient remained afebrile on the day of discharge (). discharge status: the patient was discharged to home. medications on admission: 1. plavix 75 mg by mouth once per day. 2. aspirin 325 mg by mouth once per day. 3. protonix 40 mg by mouth once per day. condition at discharge: the patient was neurologically stable at the time of discharge. discharge instructions/followup: the patient was instructed to follow up with dr. in the office in one month for a follow-up visit at which time he will be scheduled for the coiling of the residual through the stent interstices. , m.d. dictated by: medquist36 procedure: endovascular (total) embolization or occlusion of head and neck vessels diagnoses: unspecified essential hypertension cerebral aneurysm, nonruptured
