Case 1 • BP/P 159/89, 80/min, Urine alb 2+ • Rechecked BP 165/98, 78/min • No symptoms of PET • Blood test • Hb 13.6, WCC 6.9, Plt 121 • RFT 139/4.2/4.7/82 • ALP 179 • Alb 29, ALT 18 • Urate 0.42 (0.16-0.39)
Case 1 • Diagnosis: Pre-eclampsia complicating twin pregnancy • Emergency Lower segment Cesarean Section under spinal anaesthesia • Operation uneventful, blood loss 300ml • Both twins’ Apgar scores satisfactory • BP at end of operation 130/74, 88/min • Transferred to labour ward post op
Case 1 • Upon arrival to Labour ward • BP 186/93, 55/min • Headache +ve, no blurred vision/ other symptoms of PET • Started on MgSO4 infusion 4g as loading, 1g/hr • Given nifedipine5mg q4h poprn if SBP >= 160 for BP control
Case 1 • Noticed sudden onset of slurring of speech the next morning • Examination showed cerebellar signs with nystagmus, GCS 15/15, no other symptoms of PET e.g. epigastric pain • Urgent CT Brain
Case 1 • Urgent CT Brain • Hypodense areas in pons, midbrain, bilateral basal ganglia and thalami • Taken over to ICU for close monitoring
Case 1 • Seen by Neurology colleagues: • Bilateral past pointing • Horizontal gaze limited in abduction and adduction, left worse than right side • Slurred speech • No other focal neurological deficits • CT Brain: hypo-densities over bilateral pons, midbrain, thalami, basal ganglia • Likely pre-eclampsia related cerebral dysfunction, causing cerebral flow limitation over posterior circulation • For BP control
Case 1 • BP controlled by labetalol infusion • Reviewed by neurology 18/11/2010 • Sustained bilateral horizontal nystagmus with impaired left lateral and vertical gaze, mild divergent squint, features suggestive of left pontine, midbrain and thalamic dysfunction, dysarthria with wet voice compatible with bulbar dysfunction • Condition showed improvement after control of BP and MgSO4 infusion • Suggested for MRI
Case 1 • MRI Brain and brain stem with contrast + MR angiography 19/11/2010 • T2 hyperintense signal in central portion of the pons, medulla and midbrain, also patchy seen in bilateral basal ganglia & external capsular regions • No abnormal contrast enhancement • Small patchy areas of restricted diffusion in pons and medulla • No obvious signal change suggestive of intracranial haemorrhage • MRA showed patent and normal intracerebral arteries
Case 1 • BP gradually stabilized with amlodipine, methyldopa, minoxidil, weaned off labetalol • Clinically improving diplopia/ slurring of speech • Discharged from ICU on 22/11/2010 • CT Brain repeated 24/11/2010
