The report of the International Subarachnoid Aneurysm Trial (ISAT) study showed that coil embolization was superior to neck clipping as a treatment for subarachnoid hemorrhage (SAH) 1. Recently, some results of treatments for unruptured aneurysm via coil embolization and neck clipping have been reported2,3. We compared the results of coil embolization and neck clipping in our institute. Generally better outcomes were obtained by endovascular surgery than by neck clipping. Postoperative ischemic strokes occurred in one case (1.8%) as a major stroke and in three cases (5.6%) as a minor stroke among coil-treated cases, and in two cases(2.6%) as a major stroke, and in seven cases(9.0%) as a minor stroke among neck clipping cases. Other complications after these treatments were six cases of subdural effusion/hematoma, four cases of infection, two cases of epidural hematoma, one abducens nerve palsy, one hydrocephalus, and one acute myocardial infarction among 78 neck clipping cases, and two subcutaneous hematoma, one pseudoaneurysm at the puncture points, one direct carotid-cavernous fistula among 54 coil-treated cases. Four coil-treated cases, in which introduction of microcatheters to the aneurysm was impossible, were treated completely by neck clipping after endovascular treatments. In terms of modified Rankin Scale(mRS) three months after treatments, while mRS 3 was noted in only one case in the endovascular treatment group, there were one case of mRS 3, two cases of mRS 4, and two cases of mRS 5 in the neck clipping group. Duration of hospitalization averaged 11.9 days in the endovascular group and 24.1 days in the neck clipping group. The results of endosaccular enbolizations as treatment of the unruptured aneurysm seems to be better than neck clipping. However, not all cases of unruptured aneurysms can be treated by coil embolization due to the width of aneurysmal neck and relation of the aneurysm to parent arteries. Therefore, surgeons should also be able to perform neck clipping as an alternative modality.

The aim of our study was to identify risk factors for recanalization 6 months after coil embolization using clinical data followed by computational fluid dynamics (CFD) analysis. Methods: Firstly, clinical data of 184 patients treated with coil embolization were analyzed retrospectively. Secondly, aneurysm models for high/low recanalization risk were generated based on ROC curves and their cut-off points. Afterward, CFD was utilized to validate the results. Results: In multivariable analysis, aneurysm filling during the first embolization was an independent risk factor whilst packing density was a protective factor of recanalization after 6 months in patients with aSAH. For patients with unruptured aneurysms, packing density was found to be a protective factor whilst the aneurysm neck size was an independent risk factor. Complex flow pattern and multiple vortices were associated with aneurysm shape and were characteristic of the high recanalization risk group. Conclusions: Statistical analysis suggested that there are various factors influencing recanalization risk. Once certain values of morphometric parameters are exceeded, a complex flow with numerous vortices occurs. This phenomenon was revealed due to CFD investigations that validated our statistical research. Thus, the complex flow pattern itself can be treated as a relevant recanalization predictor.

Abstract BACKGROUND Though endovascular techniques and procedural devices continue to advance, recurrence of embolized aneurysms is still problematic. Enlarging size during follow-up is the presumed basis of recanalization in some lesions, but such growth has not been adequately investigated. OBJECTIVE To generate estimates of growth in coiled aneurysms with major recanalization, focusing on incidence and risk factors involved. METHODS A cohort of 134 patients harboring 139 aneurysms were retrospectively reviewed, each subjected to re-embolization for major recanalization after initial coil embolization. Cumulative medical records and radiological data were assessed. The aneurysms were grouped by nature of recanalization, either related or unrelated to growth. Growth was defined as >50% increase in aneurysm volume (including coil mass) at the time of re-embolization, compared initial status. Aneurysm volumes were determined by volume of coil mass within full confines of the aneurysm. Univariate and multivariate analyses were performed to identify risk factors predisposing to growth. RESULTS Major recanalization was growth related in 74 coiled aneurysms (53.2%) and unrelated to growth (by coil compaction) in 65 (46.8%). Multiple logistic regression analysis indicated that growth of coiled aneurysm was linked to aneurysms initially ruptured at presentation (P = .002) and aneurysm size <7 mm (P < .001). Cumulative growth rates were as follows: 14 (18.9%), 6 mo; 18 (24.3%), 12 mo; 13 (17.6%), 24 mo; 10 (13.5%), 36 mo; and 19 (25.7%), >36 mo. CONCLUSION Our data suggest that aneurysms presenting with hemorrhage and small-sized aneurysms (<7 mm) are predisposed major recanalization by growth after coil embolization, as opposed to coil compaction.

Background: There are known correlations between intracranial aneurysm size as well as underlying demographic risk factors that lead to aneurysm rupture. The treatment of unruptured aneurysms is predicated on this, however selecting which unruptured aneurysms should be treated can be difficult. It is thought that formation, growth and eventual rupture of aneurysms is due to an underlying inflammatory process, which has been shown in pathological studies to exist within aneurysmal walls. The inflammatory milieu within a live aneurysmal sac and its implications for aneurysmal rupture is not currently known. Objective: To determine the presence of inflammatory markers within unruptured aneurysm sacs. Methods: We analyzed prospectively collected data from a database of patients who presented for unruptured aneurysm coil embolization over the span of 25 months to a University Hospital. These patients had blood samples withdrawn from the aneurysm sac immediately prior to coil embolization. This blood was sent for testing, with controls provided by blood sampled from the aneurysm parent vessel. Complement C3 and C4 levels from the aneurysm and parent vessel were then compared using column tables with paired t-test analysis. Results: A total of 8 patients were enrolled. The mean age (± SD) of treated patients was 68 (±15.3) years and 7 (87.5%) were women. 5 aneurysms (62.5%) were in the anterior circulation. Aneurysm size ranged from 5mm to 14mm, mean size 8.9mm (± 3.1mm). 5 patients (62.5%) were white while 7 patients (87.5%) had history of hypertension. C3 and C4 analysis showed a consistent decrease of complement values within the aneurysm as compared to the parent vessel. (For C3, mean of differences [MD] was 9.375, 95% confidence interval [CI] 5.56-13.19. For C4, MD was 1.500, 95% CI 0.50-2.50.) Conclusion: There is an observed decrease in complement values within unruptured aneurysms, suggestive of ongoing classic complement pathway activation. This supports the aneurysm inflammation model, which shows complement deposition in aneurysm walls. Our data suggests that this process is ongoing in live unruptured aneurysms and could be possibly targeted in future aneurysm trials. Further investigation is needed.

Few Data

Anticoagulant therapy is usually used after endovascular operations like coil embolization of aneurysms, or for thromboembolic diseases such as myocardial infarction. Few data exist regarding hemorrhage from benign brain tumors during systemic heparinization with the exception of pituitary adenomas1,2. We experienced two cases of hemorrhage from benign brain tumors during systemic heparinization. The first patient had an unruptured aneurysm in her suprasellar tumor. She underwent coil embolization to prevent hemorrhage during the subsequent tumorectomy. During and after the endovascular operation, she was heparinized and she suffered a hemorrhage from the tumor on the first postoperative day. The second patient had a suprasellar tumor and was heparinized prophylactically for myocardial infarction. He had an intratumoral hemorrhage on the fifth day after the start of the heparinization. This small series suggests that systemic heparinization with brain tumors, even when they are benign, is very dangerous, and further studies with a larger patient base are warranted.
