Systemic metabolism and energy consumption after microsurgical clipping and endovascular coiling for aneurysmal subarachnoid hemorrhage

OBJECTIVE The Barrow Ruptured Aneurysm Trial (BRAT) was a single-center trial that compared endovascular coiling to microsurgical clipping in patients treated for aneurysmal subarachnoid hemorrhage (aSAH). However, because patients in the BRAT were treated more than 15 years ago, and because there have been advances since then—particularly in endovascular techniques—the relevance of the BRAT today remains controversial. Some hypothesize that these technical advances may reduce retreatment rates for endovascular intervention. In this study, the authors analyzed data for the post-BRAT (PBRAT) era to compare microsurgical clipping with endovascular embolization (coiling and flow diverters) in the two time periods and to examine how the results of the original BRAT have influenced the practice of neurosurgeons at the study institution. METHODS In this retrospective cohort study, the authors evaluated patients with saccular aSAHs who were treated at a single quaternary center from August 1, 2007, to July 31, 2019. The saccular aSAH diagnoses were confirmed by cerebrovascular experts. Patients were separated into two cohorts for comparison on the basis of having undergone microsurgery or endovascular intervention. The primary outcome analyzed for comparison was poor neurological outcome, defined as a modified Rankin Scale (mRS) score > 2. The secondary outcomes that were compared included retreatment rates for both therapies. RESULTS Of the 1014 patients with aSAH during the study period, 798 (79%) were confirmed to have saccular aneurysms. Neurological outcomes at ≥ 1-year follow-up did not differ between patients treated with microsurgery (n = 451) and those who received endovascular (n = 347) treatment (p = 0.51). The number of retreatments was significantly higher among patients treated endovascularly (32/347, 9%) than among patients treated microsurgically (6/451, 1%) (p < 0.001). The retreatment rate after endovascular treatment was lower in the PBRAT era (9%) than in the BRAT (18%). CONCLUSIONS Similar to results from the BRAT, results from the PBRAT era showed equivalent neurological outcomes and increased rates of retreatment among patients undergoing endovascular embolization compared with those undergoing microsurgery. However, the rate of retreatment after endovascular intervention was much lower in the PBRAT era than in the BRAT.

ABSTRACT Subarachnoid hemorrhage (SAH) with subdural hygroma (SH) was rarely reported after endovascular coiling. A 60-year-old male presented with impaired consciousness and convulsions due to SAH from a ruptured aneurysm. It was managed by endovascular coiling 20 h after the onset of symptoms. Serial brain imaging for 2 weeks revealed progressive bilateral SHs, more on contralateral side of leaking aneurysm. Management of SH was discussed in a multidisciplinary setting to be conservative as there was neither significant mass effect nor hydrocephalus. The patient recovered neurologically except for mild dysarthria. The SH persisted for 2 months and then cleared gradually. We concluded that SH may arise and become symptomatic as an unusual sequela of post-coiling of a ruptured intracranial aneurysm, in which the SH can complicate the clinical course of SAH. However, the symptomatic SH may resolve spontaneously and completely without any intervention, but needs meticulous neurological assessment and follow-up.

Background and Objective: The International Subarachnoid Aneurysm Trial (ISAT) showed a greater likelihood of survival free 1 year disability in patients undergoing endovascular coiling who were started on antiplatelet agents after SAH compared to ones undergoing neurosurgical clipping. However, data on safety of acute parental antiplatelet agents after aneurysmal coiling is lacking. We report on the safety of IV Eptifibatide (rapidly reversible Glyprotein IIbIIIa inhibitor) on patients presenting with acute subarachnoid hemorrhage undergoing endovascular coiling for aneurysmal embolization. Methods: All the patients from 2009-13 who presented to our university affiliated comprehensive stroke center with aneurysmal subarachnoid hemorrhage and underwent endovascular coiling were included for the study. Patients that received IV Eptifibatide for various reasons including acute need for stent assist coiling after securing the ruptured aneurysm with endovascular coiling were reviewed. Eptifibatide was administered intra-arterially as a 135-μg/kg single-dose bolus, and then continued on intravenous infusion of 0.5-μg/kg/min post-procedurally. Charts were reviewed for all patients to assess for medical/procedural complications including symptomatic and asymptomatic intra- and extra-cranial hemorrhages, groin hematomas, epistaxis and gross hematuria. Results: Of the total of 93 patients treated with coil embolization during this period, 5 patients (mean age 56 years, 20% male [n=1]) received acute intra-procedural Eptifibatide followed by IV infusion for a mean duration of 77 hours (range 20-130 hours). Various reasons for use of Eptifibatide included: stent assist coiling [n=2], multiple stents for flow diversion [n=1], partial coil prolapse [n=1] and vascular lumen flow compromise [n=1]. None of the patients demonstrated symptomatic/asymptomatic hemorrhage, groin hematoma, epistaxis or hematuria. Conclusion: Our results may highlight safety of administering IV Eptifibatide to prevent thrombotic complications after endovascular coil embolization in select patients with aneurysmal subarachnoid hemorrhage. Multicenter prospective trials are warranted to corroborate our findings.

Object Increasing evidence exists that treatment of complex medical conditions in high-volume centers is found to improve outcome. Patients with subarachnoid hemorrhage (SAH), a complex disease, probably also benefit from treatment at a high-volume center. The authors aimed to determine, based on published literature, whether a higher hospital caseload is associated with improved outcomes of patients undergoing treatment after aneurysmal subarachnoid hemorrhage. Methods The authors identified studies from MEDLINE, Embase, and the Cochrane Library up to September 28, 2012, that evaluated outcome in high-volume versus low-volume centers in patients with SAH who were treated by either clipping or endovascular coiling. No language restrictions were set. The compared outcome measure was in-hospital mortality. Mortality in studies was pooled in a random effects meta-analysis. Study quality was reported according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria. Results Four articles were included in this analysis, representing 36,600 patients. The quality of studies was graded low in 3 and very low in 1. Meta-analysis using a random effects model showed a decrease in hospital mortality (OR 0.77 [95% CI 0.60–0.97]; p = 0.00; I2 = 91%) in high-volume hospitals treating SAH patients. Sensitivity analysis revealed the relative weight of the 1 low-quality study. Removal of the study with very low quality increased the effect size of the meta-analysis to an OR of 0.68 (95% CI 0.56–0.84; p = 0.00; I2 = 86%). The definition of hospital volume differed among studies. Cutoffs and dichotomizations were used as well as division in quartiles. In 1 study, low volume was defined as 9 or fewer patients yearly, whereas in another it was defined as fewer than 30 patients yearly. Similarly, 1 study defined high volume as more than 20 patients annually, and another defined it as more than 50 patients a year. For comparability between studies, recalculation was done with dichotomized data if available. Cross et al., 2003 (low volume ≤ 18, high volume ≥ 19) and Johnston, 2000 (low volume ≤ 31, high volume ≥ 32) provided core data for recalculation. The overall results of this analysis revealed an OR of 0.85 (95% CI 0.72–0.99; p = 0.00; I2 = 87%). Conclusions Despite the shortcomings of this study, the mortality rate was lower in hospitals with a larger caseload. Limitations of the meta-analysis are the not uniform cutoff values and uncertainty about case mix.
