Abstract Background Some studies have shown a protective association between aspirin use and subarachnoid haemorrhage (SAH). Other studies have found no relationship or the reverse. These studies differ in their study populations and definitions of SAH. Aims Our aim was to establish 1) if there is an association between aspirin and SAH, 2) how this differs between the general population and those with intracranial aneurysms. Summary of review Studies reporting aspirin use and the occurrence of SAH were included and grouped based on population (general population vs aneurysm population). Odds ratios, hazard ratios and confidence intervals were combined in random-effects models. 11 studies were included. Overall, there was an association between aspirin and SAH (OR 0.68 [0.48, 0.96]). However, populations were diverse and heterogeneity between studies high (p<0.00001), questioning the validity of combining these studies and justifying analysis by population. In the general population there was no difference in aspirin use between individuals with and without SAH (OR 1.15 [0.96, 1.38]). In patients with intracranial aneurysms, aspirin use was greater in patients without SAH (OR 0.37 [0.24, 0.58]), although these studies were at higher risk of bias. Conclusions There is an association between aspirin use and SAH in patients with intracranial aneurysms. This apparent protective relationship is not seen in the general population. Prospective randomised studies are required to further investigate the effect of aspirin on unruptured intracranial aneurysms.

Abstract OBJECTIVE To compare the risk of shunt-dependent hydrocephalus after treatment of ruptured intracranial aneurysms by clipping versus coiling. METHODS We analyzed 596 patients prospectively added to our database from July of 1999 to November of 2005 concerning the risk of shunt dependency after clipping versus coiling. Factors analyzed included age; sex; Hunt and Hess grade; Fisher grade; acute hydrocephalus; intraventricular hemorrhage; angiographic vasospasm; and number, size, and location of aneurysms. In addition, a meta-analysis of available data from the literature was performed identifying four studies with quantitative data on the frequency of clip, coil, and shunt dependency. RESULTS The institutional series revealed Hunt and Hess grade, Fisher grade, acute hydrocephalus, intraventricular hemorrhage, and angiographic vasospasm as significant (P &lt; 0.05) risk factors for shunt dependency after a univariate analysis. In a multivariate logistic regression analysis, we isolated intraventricular hemorrhage, acute hydrocephalus, and angiographic vasospasm as independent, significant risk factors for shunt dependency. The meta-analysis, including the current data, revealed a significantly higher risk for shunt dependency after coiling than after clipping (P = 0.01). CONCLUSION Clipping of a ruptured aneurysm may be associated with a lower risk for developing shunt dependency, possibly by clot removal. This might influence long-term outcome and surgical decision making.

Background and purposeThe Medina embolization device (MED) is a new flow disruption device combining the design of a detachable coil with an intrasaccular flow disrupter. Safety and short-term angiographic effectiveness of this device have recently been reported. However, long-term angiographic results are lacking. We report herein the 18 months’ angiographic outcome in patients treated for a wide-neck intracranial aneurysm with the MED.Materials and methodsNineteen patients (17 female, mean age 50 years) with 20 wide-neck intracranial aneurysms (six ruptured; 14 unruptured) were treated by the MED between January 2015 and June 2016. Procedure-related complications were systematically recorded; discharge and 6–9 months' follow-up modified Rankin Scale scores were assessed. Angiographic mid-term and long-term follow-up were performed with a mean delay of 6.4±1.5 months (n=16 aneurysms) and 17.7±4.2 months (n=15 aneurysms), respectively. Occlusion rates were evaluated after the procedure and at the mid-term and long-term follow-up using the Roy-Raymond scale.ResultsEmbolization with the MED was feasible in all except two cases (2/20, 10%). One per-procedural perforation was recorded (1/20, 5%) and one MED deployment failed because of the aneurysm’s shape (1/20, 5%). Three cases of thromboembolic complications were observed (3/20, 15%). Only one thromboembolic complication was responsible for clinical sequelae. Grade A occlusion rate was 61% (11/18) after the procedure, 75% at 6 months' follow-up (12/16), and 80% (12/15) at long-term follow-up. Two cases (2/18, 11%) of recanalization at mid-term were documented angiographically. No recanalization occurred between the mid-term and long-term follow-up.ConclusionMED is a hybrid embolization device, combining properties of a conventional coil with those of an intrasaccular flow disrupter. Our series focusing on long-term angiographic follow-up shows a satisfactory long-term occlusion rate. Larger series with longer angiographic follow-up times are warranted to confirm these preliminary results.

Endovascular treatment is a safe and efficient therapy for intracranial aneurysms with lower complication and mortality rates compared to surgical clipping. Wide-neck aneurysms still represent a challenge to complete and safe aneurysm occlusion in spite of techniques such as stent-assisted or balloon-assisted coiling, developed in order to achieve better occlusion rates. These techniques themselves may lead to further complications, so alternative methods such as the dual microcatheter technique were developed. This technique assumes that, via two microcatheters inserted into an aneurysm, simultaneous deployment of two coils achieves a stable coil frame without the use of adjunctive devices. The aim of this paper is to present a successfully treated basilar tip wide-neck aneurysm treated with the dual microcatheter technique.Case report. A 46-year-old male patient with acute onset of severe headache presented in the emergency room with altered state of consciousness. Non-enhanced CT scan showed subarachnoid and intraventricular haemorrhage. CT angiography revealed a wide-neck basilar tip aneurysm. Digital subtraction angiography confirmed the presence of an aneurysm with a wide, 4.9 mm neck.Dual microcatheter technique was chosen as the first treatment option, while a hypercompliant balloon was kept as backup. Two microcatheters were placed inside de aneurysm and two coils were introduced in order to form a stable framing coil mass that served as a support for further coils deployed in an alternately manner through each microcatheter. No procedural complication occurred, and the patient’s evolution was uneventful with no neurological deficits at discharge.Conclusion. The dual microcatheter technique is a safe and effective therapeutic option for wide-neck ruptured or unruptured intracranial aneurysms. Periprocedural complication rates are similar to simple coiling or balloon-assisted coiling, but lower than for stent-assisted coiling.
