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: mrs. is a 50 year old woman without any documented significant medical history when first seen; her family was not present to confirm. she awoke at 4:00 a.m. with a headache. at 11:00 a.m., she walked into her son's bedroom and woke him. she was speaking normally at that time. she went back to sleep and the son heard mumbling. she was then found with right arm weakness and incoherent speech at around 11:30 a.m. at , the patient was noted to have a left gaze preference, right arm and face weakness. a head ct scan was normal. they were going to give her intravenous tpa for a presumed left middle cerebral artery stroke, but she had overt blood on rectal examination. a gastroenterologist did an anoscopy in the emergency room and she had clotted blood superiorly. the patient was transferred to for intra-arterial tpa. at that point, an examination was done which was after 4 mg of ativan that was given for extreme restlessness. eyes spontaneously opening, no response to verbal command. left gaze preference. able to doll eyes past midline to the right. reactive pupils. vigorous spontaneous movements of the left arm and leg. right leg spontaneously flexed to slide heel back toward buttocks. right arm passively drooped, which did not protect her face when it was dropped. right arm extended with strong muscle contraction into painful stimulus and a right babinski sign was present. the patient was paralyzed and sedated and intubated and taken emergently to the angiography suite at 2:50 p.m. there was a dissection of the proximal left internal carotid artery just distal to the bifurcation. contrast injection via the right carotid showed collateral filling of the left aca but no filling past the m1 segment of the left mca. the internal carotid could not be recanalized so the catheter was fed through the right anterior cerebral artery into the anterior communicating artery to inject tpa into the left mca. tpa injection began at 4:55 p.m., a total of 20 mg of tpa was injected into left mca without appreciable change in the left mca filling. the patient was taken for a repeat ct scan of her head, which showed signs of early ischemia in the left inferior division of the mca territory and small basal ganglia bleed. hospital course: the patient was then transferred to the neurology intensive care unit and hydrated. her blood pressure was controlled to between 140 and 170. she was started on intravenous heparin without a bolus for a goal partial thromboplastin time between 60 and 80, tending towards the lower end. a repeat head ct showed a small bleed but no extension. intravenous heparin was continued. the patient remained intubated. she was monitored with frequent neurologic checks, with the concern that she would need surgical decompression since her stroke was so large. neurosurgery followed her as well. she did not end up needing neurosurgical decompression. in addition, her temperature was controlled with a cooling blanket for temperatures greater than 100. the patient was planned to be extubated on . she was extubated on successfully and started on c-pap. the femoral line was taken out. hydralazine was added for blood pressure control. tube feeds were started on as well with insulin coverage for her fingersticks. physical therapy and occupational therapy saw the patient on , with a determination that she had a limited ability to participate, however, that she good rehabilitation potential. on , coumadin was started. a urinalysis was sent and it was determined that the patient had a urinary tract infection, which was treated with ciprofloxacin. at that point, she began to get out of bed to chair. on , she was transferred to the floor team, where her coumadin was continued as well as her heparin drip, and her blood pressure remained well controlled. a swallow evaluation was done, in which the patient was unable to cooperate, and she was put in for percutaneous endoscopic gastrojejunostomy tube placement. this was not able to be done over the holiday, so this was held. on , the patient was noted to have a decreasing hematocrit. in addition, she was cool and clammy, although her neurological examination was unchanged. she was increasingly agitated. she also was noted to have heavy vaginal bleeding and have some blood from the nasogastric tube. at midnight, her hematocrit returned at 24. it was decided that the heparin drip needed to be stopped, which we did. a ct scan of the abdomen and pelvis was done and patient was found to have a large retroperitoneal bleed. a vascular surgery consult was requested at that point. the patient was then transfused. the heparin and coumadin were held and her inr was corrected with fresh frozen plasma. she was then transferred back to the intensive care unit to monitor her status and for the fast correction of her coagulopathy. after five units of blood, the patient's hematocrit remained stable at around 30. in addition, she received two units of fresh frozen plasma, with correction of her inr down to 1.2 and, furthermore, she received vitamin k as well. in addition, she was then transferred out to the floor again, after her hematocrit was stable on . on that day, the patient finally had her gastrojejunostomy tube put in. in addition, we noted the heavy vaginal bleeding and a consult was obtained from gynecology. they noted that the patient had a history of irregular periods recently, with the most recent period two weeks ago. a pelvic ultrasound was obtained, transvaginal not done, showing a normal sized uterus, normal right ovary and no endometrial stripe observed. at that point, the patient had several hours with a minimal amount of blood, with the odor of menstrual blood. the gynecology service determined that the vaginal bleeding was most likely her regular menses and, during perimenopause, they see periods that are often very irregular. they felt that, since she had her anticoagulation reversed, it was unlikely that this was the cause of her menorrhagia, with the comment that, if the vaginal bleeding persisted for more than another week or if she were soaking more than one pad per hour, they could consider hormone therapy to stop her period. the patient was screened by physical therapy and occupational therapy and was then deemed to be stable for discharge. furthermore, her anticoagulation and antiplatelet agents were held. they can be started one week after the bleed, which would be . discharge medications: regular insulin sliding scale for fingersticks, see page one. lopressor 75 mg per g-tube b.i.d., hold for systolic blood pressure less than 170. hydralazine 20 mg per g-tube q.6h., old for systolic blood pressure less than 160. normal saline. trazodone 50 mg per g-tube q.h.s. and p.r.n. insomnia. tube feeds: promod with fiber, goal of 60 cc/hour; free water boluses 200 cc per g-tube t.i.d. heparin 5,000 unit s.c.b.i.d. discharge diagnoses: left inferior mca stroke. left carotid dissection. retroperitoneal bleed. urinary tract infection. , m.d. dictated by: medquist36 procedure: insertion of endotracheal tube enteral infusion

site not specified cerebral artery occlusion, unspecified with cerebral infarction hemorrhage, unspecified unspecified circulatory system disorder
