Timelines and rebleeds in patients admitted into neurosurgical care for aneurysmal subarachnoid haemorrhage.

ABSTRACT:

Background

Mortality and morbidity of aneurysmal subarachnoid haemorrhage (aSAH) remain high, and prognosis is influenced by multiple non-modifiable factors such as aSAH severity. By analysing the chronology of aSAH management, we aim at identifying modifiable factors with emphasis on the occurrence of rebleeds in a setting with 24/7 surgical and endovascular availability of aneurysm repair and routine administration of tranexamic acid.

Methods

Retrospective analysis of institutional quality registry data of aSAH cases admitted into neurosurgical care during the time period 01 January 2013-31 December 2017. We registered time and mode of aneurysm repair, haemorrhage patterns, course of treatment, mortality and functional outcome. Rebleeding was scored along the entire timeline from ictus to discharge from the primary stay.

Results

We included 544 patients (368, 67.6% female), aged 58 ± 14 years (range 1-95 years). Aneurysm repair was performed in 486/544 (89.3%) patients at median 7.4 h after arrival and within 3, 6, 12 and 24 h in 26.8%, 44.7%, 73.0% and 96.1%, respectively. There were circadian variations in time to repair and in rebleeds. Rebleeding prior to aneurysm repair occurred in 9.7% and increased with aSAH severity and often in conjunction with patient relocations or interventions. Rebleeds occurred more often during surgical repair outside regular working hours, whereas rebleeds after repair (1.8%) were linked to endovascular repair.

Conclusions

The risk of rebleed is imminent throughout the entire timeline of aSAH management even with ultra-early aneurysm repair. Several modifiable factors can be linked to the occurrence of rebleeds and they should be identified and optimised within neurosurgical departments.

Project description:The prognosis of patients with aneurysmal subarachnoid haemorrhage requiring decompressive craniectomy is usually poor. Proper selection and early performing of decompressive craniectomy might improve the patients' outcome. We aimed at developing a risk score for prediction of decompressive craniectomy after aneurysmal subarachnoid haemorrhage. All consecutive aneurysmal subarachnoid haemorrhage cases treated at the University Hospital of Essen between January 2003 and June 2016 (test cohort) and the University Medical Center Freiburg between January 2005 and December 2012 (validation cohort) were eligible for this study. Various parameters collected within 72 h after aneurysmal subarachnoid haemorrhage were evaluated through univariate and multivariate analyses to predict separately primary (PrimDC) and secondary decompressive craniectomy (SecDC). The final analysis included 1376 patients. The constructed risk score included the following parameters: intracerebral ('Parenchymal') haemorrhage (1 point), 'Rapid' vasospasm on angiography (1 point), Early cerebral infarction (1 point), aneurysm Sac > 5 mm (1 point), clipping (' S urgery', 1 point), age U nder 55 years (2 points), Hunt and Hess grade ≥ 4 ('Reduced consciousness', 1 point) and External ventricular drain (1 point). The PRESSURE score (0-9 points) showed high diagnostic accuracy for the prediction of PrimDC and SecDC in the test (area under the curve = 0.842/0.818) and validation cohorts (area under the curve = 0.903/0.823), respectively. 63.7% of the patients scoring ≥6 points required decompressive craniectomy (versus 12% for the PRESSURE < 6 points, P < 0.0001). In the subgroup of the patients with the PRESSURE ≥6 points and absence of dilated/fixed pupils, PrimDC within 24 h after aneurysmal subarachnoid haemorrhage was independently associated with lower risk of unfavourable outcome (modified Rankin Scale >3 at 6 months) than in individuals with later or no decompressive craniectomy (P < 0.0001). Our risk score was successfully validated as reliable predictor of decompressive craniectomy after aneurysmal subarachnoid haemorrhage. The PRESSURE score might present a background for a prospective randomized clinical trial addressing the utility of early prophylactic decompressive craniectomy in aneurysmal subarachnoid haemorrhage.
