post evd removal: impression: interval removal of the right frontal ventriculostomy catheter. no significant changes are identified in the ventricular size, minimal amount of air is noted at the right frontal ventricular and unchanged high-density material along the ventriculostomy catheter. no new lesions are identified. brief hospital course: patient is a 78f s/p unwittnessed fall, while ambulating. she made impact with the left side of her body. she was taken to osh where imaging was performed, revealing a avm vs mass of the vermis. she was admitted to the neurosurgery icu for frequent neuromonitoring and additional evaluation. due to non-contrast head ct findings consistant with hydrocephalus, an external ventricular drain was placed at the bedside to drain csf. on , a diagnostic angiogram was performed to further characterize vermal mass; showing a vascular malformation. additionally, mri of the head was done which revealed an avm and a small right frontal infarct. radiation-oncology was consulted for possible cyberknife treatment of the avm. she will have cyberknife as an outpatient. the patient's mental status waxed and waned but was overall stable. her icp remained low and she had low output from the evd. therefore it was clamped on . ct scan showed stable intracranial findings and the drain was removed on . the patient had a speech and swallow evaluation and was able to tolerate a regular diet. she was seen and evaluated by pt and ot on who determined that she required rehab. her sutures from the evd insertion were removed on . she still has staples in place from the day the evd was removed. they will stay in place until . she was discharged to rehab on . medications on admission: zesteril, ranitidine, hctz, gabapentin, hypomax, crestor discharge medications: 1. staples you have staples in your head that must be removed on . this may be done at rehab or else this can be done in dr. office. please call to schedule this appointment. 2. docusate sodium 50 mg/5 ml liquid sig: two (2) po bid (2 times a day). 3. bisacodyl 5 mg tablet, delayed release (e.c.) sig: two (2) tablet, delayed release (e.c.) po daily (daily) as needed for constipation. 4. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 5. senna 8.6 mg tablet sig: one (1) tablet po bid (2 times a day). 6. acetaminophen 325 mg tablet sig: 1-2 tablets po q6h (every 6 hours) as needed for fever pain. 7. heparin (porcine) 5,000 unit/ml solution sig: one (1) injection tid (3 times a day). 8. heparin, porcine (pf) 10 unit/ml syringe sig: one (1) ml intravenous prn (as needed) as needed for line flush. discharge disposition: extended care facility: -
