The Impact

OBJECTIVECerebral aneurysms represent the most common cause of spontaneous subarachnoid hemorrhage. Statins are lipid-lowering agents that may expert multiple pleiotropic vascular protective effects. The authors hypothesized that statin therapy after coil embolization or surgical clipping of cerebral aneurysms might improve clinical outcomes.METHODSThis was a retrospective cohort study using the National Health Insurance Service–National Sample Cohort Database in Korea. Patients who underwent coil embolization or surgical clipping for cerebral aneurysm between 2002 and 2013 were included. Based on prescription claims, the authors calculated the proportion of days covered (PDC) by statins during follow-up as a marker of statin therapy. The primary outcome was a composite of the development of stroke, myocardial infarction, and all-cause death. Multivariate time-dependent Cox regression analyses were performed.RESULTSA total of 1381 patients who underwent coil embolization (n = 542) or surgical clipping (n = 839) of cerebral aneurysms were included in this study. During the mean (± SD) follow-up period of 3.83 ± 3.35 years, 335 (24.3%) patients experienced the primary outcome. Adjustments were performed for sex, age (as a continuous variable), treatment modality, aneurysm rupture status (ruptured or unruptured aneurysm), hypertension, diabetes mellitus, household income level, and prior history of ischemic stroke or intracerebral hemorrhage as time-independent variables and statin therapy during follow-up as a time-dependent variable. Consistent statin therapy (PDC > 80%) was significantly associated with a lower risk of the primary outcome (adjusted hazard ratio 0.34, 95% CI 0.14–0.85).CONCLUSIONSConsistent statin therapy was significantly associated with better prognosis after coil embolization or surgical clipping of cerebral aneurysms.

We evaluated long-term angiographical follow-up of cerebral aneurysms treated with detachable platinum coils with special reference to the long-term morphological outcomes of incompletely obliterated aneurysms. Serial long-term follow-up cerebral angiograms (>1 year) were obtained in 47 cases out of 134 cases treated with GDCs or IDCs from 1994 to 1999. In 47 patients, intial angiographical results demonstrated ten complete aneurysmal occlusion, seven aneurysms with a small neck remnant, twenty aneurysms with body filling and ten aneurysms with both of neck remnant and body filling. In the ten completely obliterated aneurysms, follow-up angiograms revealed no aneurysmal recanalization. In seven aneurysms with neck remnant, three remained unchanged, four showed enlargement of contrast filling in the part of the neck of the aneurysm. In twenty aneurysms with body filling, five had developed into complete obliteration, three remained unchanged, 11 had recanalization, and one aneurysm displayed regrowth. In ten aneurysms with both of neck remnant and body filling, two remained unchanged, five had recanalization, and three aneurysms displayed regrowth. Long-term angiographical follow-up results are less satisfactory in cases involving incompletely obliterated lesions. A higher incidence of recanalizations were promoted in cases with neck remnant and/or body filling. Strict follow-up angiography is mandatory when a complete obliteration is not achieved.

Unruptured Cerebral Aneurysms

Background: The recent trend of the treatment of unruptured cerebral aneurysms(UIAs) is going to be conservative. Their natural history of rupture and growth is still unkown. We present the results of annual radiological follow-up study in UIAs. Method: In recent 12 years, we have found 121patients with 148 unruptured cerebral aneurysms were followed annually using 3D-CTA or MRA. Mean follow-up period was 5.5 year. Several factors influencing rupture or growth were statistically examined. Results: Among 121 patients, 9 ruptured and 11 showed growth of UIAs. Annual rupture rate was 1.3% per year and annual growth rate was 1.6% per year. Aneurysm size was the sole factor influencing rupture(P<0.001), whereas female sex and multiplicity were major factors influencing aneurysm growth(P<0.05). Under size 3mm, annual growth rate was 3.0% whereas annual rupture rate was 0.7%. In 4-6mm, growth rate was 1.6% and rupture rate was 1.6%. In 7-9mm, growth rate was 0 and rupture rate was 5.8%. In over 10mm, growth rate was 2.9% and rupture rate was 11.6%. Within 1 year, rupture occurred in 4 cases, and growth was found in 1 case. Conclusions: By annual radiological examination, growth of UIAs was noted more frequently than aneurysm rupture. Especially UIAs under 3mm, growth was 4 times higher than rupture, radiological follow up is effective for aneurysm rupture. Within 1 year, initially found UIAs should be carefully followed in a short interval.

Background and purpose We aimed to determine the safety of intra-arterial Abciximab injection in the management of thromboembolic complications during endovascular treatment of ruptured cerebral aneurysms. Methods In a monocentric consecutive series of endovascular treatment of 783 ruptured aneurysms, 42 (5.3%) patients received Abciximab after the aneurysm was secured. Bleeding complications were registered and dichotomized as follows: new intracranial hemorrhage and peripheral bleeding. For each patient, World Federation of Neurosurgery (WFNS) subarachnoid hemorrhage (SAH) grade, shunting, and clinical outcomes in the post-operative period and at 3–6 months were recorded. Results SAH WFNS grades were as follows: grade I n = 14, grade II n = 10, grade III n = 11, grade IV n = 4, grade V n = 3. Ten patients had intracranial hematoma additionally to the SAH prior to embolization. Four patients (9.5%) presented more blood on the post-embolization CT but only one suffered a new clinically relevant intracranial hemorrhage. Two patients (4.8%) experienced significant peripheral bleeding but none were associated with long-term disabilities. Fourteen patients had a shunt installed less than 24 h prior to Abciximab injection and one less than 48 h later. At 3–6-month follow-up, 31 patients (74%) achieved a modified Rankin Scale score (mRS) of 2 or less, six patients (14%) had a mRS of 3–5, three were dead (7%), and two were lost at follow-up. Conclusion When the aneurysm is secured, intra-arterial Abciximab injection is a low complication rate treatment modality for thromboembolic events during embolization of cerebral ruptured aneurysm.

Dosing Strategy

Background: Flow diversion with the Pipeline embolization device (PED) is an effective neuro­endovascular method and increasingly accepted for the treatment of cerebral aneurysms. Acute in situ thrombosis is a known complication of PED procedures. There is limited experience in the flow diversion literature on the use of abciximab (ReoPro) for the management of acute thrombus formation in PED cases. Methods: Data were collected retrospectively on patients who received intra-arterial (IA) ReoPro with or without subsequent intravenous (IV) infusion during PED flow diversion treatment of intracranial aneurysms. Results: A total of 30 cases in patients with a mean age of 56.7 years (range 36–84) and a mean aneurysm size of 8.6 mm (range 2–25) were identified to have intraprocedural thromboembolic complications during PED treatment. IA ReoPro was administered in all cases, with 20 cases receiving increments of 5-mg boluses and 10 cases receiving a 0.125 mg/kg IA bolus (half cardiac dosing). Complete or partial recanalization was achieved in 100% of the cases. IV ReoPro infusion at 0.125 μg/kg/min for 12 h was administered postprocedurally in 22 cases with a residual thrombus. Postprocedurally, 18 patients were transitioned from clopidogrel (Plavix) to prasugrel (Effient). The majority of the cases (23/30; 77%) were discharged home. Periprocedural intracranial hemorrhage was noted in 2 cases (7%) and radiographic infarct was noted in 4 cases (13%), with an overall mortality of 0% at the time of initial discharge. Clinical follow-up was available for 28/30 patients. The average duration of follow-up was 11.7 months, at which time 23/28 (82%) of the patients had a modified Rankin Scale score of 0. Conclusions: IA ReoPro administration is an effective and safe rescue strategy for the management of acute intraprocedural thromboembolic complications during PED treatment. Using a dosing strategy of either 5-mg increments or a 0.125 mg/kg IA bolus (half cardiac dosing) can provide high rates of recanalization with low rates of hemorrhagic complications and long-term morbidity.

Abstract Purpose Single coiling may be the optimal strategy for ruptured aneurysms. But assisted techniques may be needed in some aneurysms. The authors report their experience of double microcatheter technique in the treatment of ruptured aneurysms in anterior cerebral circulation. Methods Between 2012 and 2018, 82 patients with ruptured aneurysms in anterior cerebral circulation were treated with double microcatheter technique. The clinical records, angiographic results, procedure-related complications were reviewed. Clinical and angiographic follow-up was performed. Results Completely occlusion, neck remnant and partial occlusion were achieved in 56.6%, 36.1% and 7.2% in the whole procedures, respectively. The overall rate of morbidity was 8.5% (7/82). The rate of permanent morbidity was 3.7% (3/82). Three patients (3.7%) died before discharge. There was no procedure-related mortality. The favorable outcomes were obtained in 75.6% (62/82) of the whole patients at discharge. High Hunt-Hess grade and suffering from craniotomy or EVD were risk factors for clinical outcomes at discharge. Sixty-eight patients received clinical follow-up at a mean interval of 15.75±12.71 months. Favorable outcomes were obtained in 61 (89.7%) patients. Angiographic follow-up was performed in 44 patients at an average of 13.16±13.12 months. The recurrence rate is 34.1%. Seven of them (15.9%) received retreatment. Conclusion Double microcatheter technique is a safe and effective method for treatment of ruptured aneurysms in anterior cerebral aneurysms with low morbidity. Recurrence remains a problem. Patients should be followed up regularly.
