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.

Abstract Purpose To investigate the long-term clinical and angiographic outcomes and their related predictors in endovascular treatment (EVT) of small (<5 mm) ruptured intracranial aneurysms (SRA). Methods The study retrospectively reviewed patients with SRAs who underwent EVT between September 2011 and December 2016 in two Chinese stroke centers. Medical charts and telephone call follow-up were used to identify the overall unfavorable clinical outcomes (OUCO, modified Rankin score ≤2) and any recanalization or retreatment. The independent predictors of OUCO and recanalization were studied using univariate and multivariate analyses. Multivariate Cox proportional hazards models were used to identify the predictors of retreatment. Results In this study 272 SRAs were included with a median follow-up period of 5.0 years (interquartile range 3.5–6.5 years) and 231 patients with over 1171 aneurysm-years were contacted. Among these, OUCO, recanalization, and retreatment occurred in 20 (7.4%), 24 (12.8%), and 11 (7.1%) patients, respectively. Aneurysms accompanied by parent vessel stenosis (AAPVS), high Hunt-Hess grade, high Fisher grade, and intraoperative thrombogenesis in the parent artery (ITPA) were the independent predictors of OUCO. A wide neck was found to be a predictor of recanalization. The 11 retreatments included 1 case of surgical clipping, 6 cases of coiling, and 4 cases of stent-assisted coiling. A wide neck and AAPVS were the related predictors. Conclusion The present study demonstrated relatively favorable clinical and angiographic outcomes in EVT of SRAs in long-term follow-up of up to 5 years. THE AAPVS, as a morphological indicator of the parent artery for both OUCO and retreatment, needs further validation.
