Recurrent Vasospasm After Endovascular Treatment in Subarachnoid Hemorrhage

Introduction: The rates of occurrence, predictors, and associated outcomes of subarachnoid hemorrhage (SAH) following endovascular treatment are not well studied. Methods: We retrospectively analyzed data from the Interventional Management of Stroke Trial (IMS III). This prospective trial randomized patients to intravenous (IV) rt-PA alone versus IV rt-PA followed by endovascular intervention. All patients underwent computed tomography (CT) at 24 hours post randomization. The scans were assessed by independent reviewers at a core laboratory for the presence, location, and type of intracranial hemorrhage.The primary outcome assessment was by modified Rankin Scale (mRS) score at 3 months. Results: Thirty four out of 434 (7.8%) patients who received endovascular treatment suffered SAH at 24 hours. There were 19 men (55.9%), and 19 patients were older than 70 years.In univariate analysis only pre-existing ischemic heart disease was identified as a predictor of SAH (p=0.03) while patient age was borderline significant (p=0.055). Three-monthmRS score was available for 24/34 patients with SAH and for 318/400 among the other patients. There was no difference in mortality (12.5% vs. 4.1%, p=0.167) or favorable outcome defined as mRS =<2 (41.7% vs. 53.5%, p=0.366). Conclusions: SAH following endovascular intervention for acute stroke is more common among patients with history of ischemic heart disease. It does not impact on functional outcome or mortality at 3 months.

Introduction: To report clinical outcome of aneurysmal subarachnoid hemorrhage (aSAH) patients exposed to cerebral vasospasm (CVS) targeted treatments in a systematic review and meta-analysis and compare the efficacy of endovascular and non-endovascular treatments in severe / refractory vasospasm patients. Methods: The literature was searched using PubMed, EMBASE, and The Cochrane Library database. Eligibility criteria were (1) Rated clinical outcome; (2) at least 10 patients; (3) aSAH; (4) study published in English or French (January 2006 - October 2014); and (5) methodological quality score > 10, according to STROBE criteria. Endpoint included unfavorable outcome rate, defined as mRS 3-6, GOS 1-3 or GOSE 1-4 at latest follow-up. Analyses included stratification per route of administration (oral, i.v., intra-arterial or cisternoventricular) and per study inclusion criteria (severe, CVS, refractory CVS or high risk for CVS). Univariate and multivariate subgroup analyses were performed to identify interventions associated with a better outcome. Results: Sixty-two studies, including 26 randomized controlled trials, were included (8976 patients). Overall 2490 patients had unfavorable outcome including death (random-effect weighted average: 33.7%, 99%CI, 28.1-39.7%; Q-value: 806.0, I 2 =92.7%). Clinical outcome was significantly better in severe or refractory patients for whom, on top of best medical treatment, endovascular intervention was performed (RR=0.76, IC95% [0.66-0.89], p <0.00001) whereas other route of administration didn’t show significant differences. RR of unfavorable outcome was significantly lower, vs control groups, in patients treated with Cilostazol (RR=0.46 (IC99% [0.25-0.85], P = 0.001, Q value 1.5, I 2 = 0). Conclusion: In case of CVS following aSAH, endovascular treatment in severe / refractory vasospasm patients. including intra-arterial injection of pharmacological agents or balloon angioplasty, improves outcome as compared to other route of administration.

Dissecting Aneurysms

Abstract BACKGROUND: Optimal management of bilateral vertebral artery dissecting aneurysms (bi-VDAs) causing subarachnoid hemorrhage (SAH) remains unclear. OBJECTIVE: To investigate the treatment methods and outcomes of bi-VDA causing SAH. METHODS: Seven patients were treated endovascularly for bi-VDA causing SAH. Treatment methods and outcomes were evaluated retrospectively. RESULTS: Two patients were treated with 2 overlapping stents for both ruptured and unruptured VDAs, 2 with 2 overlapping stents and coiling for ruptured VDA and with conservative treatment for unruptured VDA, 1 with internal trapping (IT) for ruptured VDA and stent-assisted coiling for unruptured VDA, 1 with IT for ruptured VDA and 2 overlapping stents for unruptured VDA, and 1 with IT for ruptured VDA and a single stent for unruptured VDA. None had rebleeding during follow-up (range, 15-48 months). All patients had favorable outcomes (modified Rankin Scale score, 0-2). On follow-up angiography at 6 to 36 months, 9 treated and 2 untreated VDAs revealed stable or improved state, whereas 3 VDAs in 2 patients showed regrowth. Of the 3 recurring VDAs, 1 was initially treated with IT but recurred owing to retrograde flow to the ipsilateral posterior inferior cerebellar artery (PICA), the second was treated with single stent but enlarged, and the last was treated with 2 overlapping stents and coiling but recurred from the remnant sac harboring the PICA origin. All 3 recurred VDAs were retreated with coiling with or without stent insertion. CONCLUSION: Bilateral VDAs presenting with SAH were safely treated with endovascular methods. However, endovascular treatment may be limited for VDAs with PICA origin involvement.

Object The goal in this study was to determine if there was a change in intracranial venous diameters after endo-vascular treatment of carotid distribution vasospasm caused by subarachnoid hemorrhage. Methods The venous diameters were measured in all patients who received intraarterial papaverine and/or balloon angioplasty for treatment of vasospasm during the study period of 3 years. To evaluate the veins of Labbé and Trolard, the straight sinus, and the superior sagittal sinus (SSS), measurements were performed in a blinded manner with the aid of a magnification loupe. Predetermined sites were evaluated on angiograms obtained before and after endovascular treatment. Forty-three treatments in 26 patients were included: 18 patients (33 territories) were treated with intraarterial papaverine alone, four (four territories) were treated with balloon angioplasty alone, and four (six territories) were treated with both papaverine infusion and angioplasty. The mean measured venous diameters increased significantly after addition of papaverine (10.9%), and also after combined papaverine and angioplasty (4.2%). There was no statistically significant increase in the mean venous diameters after angioplasty alone. If the initial intracranial pressure (ICP) was less than 15 mm Hg before treatment, the veins showed a greater tendency to dilate than if the initial ICP measurements were greater than 15 mm Hg. The straight sinus and the SSS increased more in diameter than the veins of Labbé and Trolard. There was no statistically significant correlation between the change in venous diameters with treatment and ICP. Conclusions Endovascular treatment produces measurable increases in intracranial venous diameters. However, these changes do not correlate with changes in ICP.

Contrast Enhanced Mri

Intracranial aneurysms in the neonate, presenting in the first 4 weeks of life, are exceedingly rare. They appear to have characteristics, including presentation and location, that vary from those found in adults. The authors present a case of a 28-day-old neonate with a ruptured distal middle cerebral artery (MCA) aneurysm. Initial noninvasive imaging with transfontanelle ultrasound and CT confirmed intraparenchymal and subarachnoid hemorrhage. Contrast-enhanced MRI revealed a 14-mm ruptured fusiform MCA aneurysm that was not identified on time-of-flight magnetic resonance angiography (MRA). Microsurgical treatment was performed with partial neurological recovery. A comprehensive review of the literature from 1949 to 2017 revealed a total of 40 aneurysms in 37 neonates, including the present case. The most common presenting symptom was seizure. Although subarachnoid hemorrhage was the most common form of hemorrhage, 40% had intraparenchymal hemorrhage. The median aneurysm size was 10 mm (range 2–30 mm) and the most common location was the MCA, with two-thirds of cases involving the distal intracranial vasculature. Over the last 10 years, there has been a trend of increasing noninvasive diagnosis of ruptured cerebral aneurysms in neonates, with CT angiography and contrast-enhanced MRI being the most useful diagnostic modalities. The use of contrast-enhanced MRI may improve sensitivity over time-of-flight MRA. Microsurgical treatment was the most common treatment modality overall, with increased use of endovascular treatment in the last decade. Most patients underwent microsurgical vessel ligation or endovascular parent vessel occlusion. There were high rates of neurological recovery after microsurgical or endovascular treatment, particularly for patients with distal aneurysms.
