Spectrum of neurological complications in HELLP syndrome.

BACKGROUND

Hemolysis (H), elevated liver enzymes (EL), and low platelets (LP), HELLP syndrome is the extended spectrum of severe preeclampsia and is associated with high mortality. A large proportion of mortality can be attributed to catastrophic central nervous system events.

AIMS: The purpose of this study was to access the clinical manifestations, radiological abnormalities and outcome in patients of HELLP syndrome with neurological manifestations.

SETTING

Obstetric unit and neurology intensive critical unit (ICU) of an academic medical center.

STUDY

DESIGN

Retrospective study.

SUBJECTS AND

METHODS

Case records of all obstetrical patients who were admitted between January 2012 and December 2012 were screened and data was collected from those patients who were diagnosed with HELLP syndrome with neurological complications. It was entered into a structured performa and analyzed using percentages .

RESULTS

During the study period; 1,166 deliveries were conducted, 108 patients had pregnancy-induced hypertension (PIH); and of the 12 patients with HELLP, eight (66%) patients had neurological complications. The presenting neurological features were seizures (four), focal neurological deficits (two), and encephalopathy (two). Of the eight patients, in six patients neuroimaging showed features of posterior reversible encephalopathy syndrome (PRES), three of them had associated hemorrhage, and two patients had isolated intracranial hemorrhage. All except two were discharged home.

CONCLUSIONS

Neurological complications are not uncommon in patients with HELLP syndrome and a high index of suspicion is essential. Aggressive multidisciplinary approach is the key to reduce the morbidity and mortality.
