Abstract This 41-years-old female presented with somnolence, confusion and nuchal rigidity. Preoperative angio-CT scan showed two aneurysm located on both internal carotid artery (ICA) at the site of posterior communicating artery (PComA). During surgery we discovered another dilatation on the origin of left ophtalmic artery that proves to be an infundibullum. We clipped the two communicating posterior aneurysm from the left side and the ophtalmic infundibullum was wrapped. Seven days after surgery the neurological status was improved and she was transferred to the Neurological department.

Objectives: The aim was to analyze the risk factors for intraoperative rupture (IR) of cerebral aneurysm and for temporary clips (TC) use, as well as their influence on the final postoperative outcome. Methods: Retrospective study was done 72 IR patients, and on 75 TC patients. For patients with or without IR, as well as for the patients with or without TK, outcome of the treatment aneurysm size and localization, preoperative clinical state and operative timing was analyzed, and statistical significance of obtained differences was tested. Results: IR occurred in 40% of anterior cerebral artery aneurysms and in 16.7% of internal carotid artery aneurysms (p>0.05), while TCs were used in 52% of middle cerebral artery aneurysms and 34.8% of internal carotid artery aneurysms (p>0.05). Average size was 17.3 mm for aneurysms with IR and 11.7 mm for those without IR (p>0.05). Aneurysms were significantly larger in patients with TCs, than in patients without TCs (16.7 mm and 9.4 mm respectively, p<0.05). Preoperative period was 10.2 days for patients with IR, and 16.8 days for patients without IR (p<0.05). Favorable outcome was observed in 71.4% of patients with IR and in 70.6% of those without IR, as well as in 76.4% of patients who required TC and in 75.6% of cases without TC (p>0.05). Average duration of temporary occlusion was 5.8 min for patients with favorable outcome and 15 min for patients with poor outcome (p<0.05). Conclusions: Incidence of IR mostly depended on the duration of preoperative interval, while the frequency of TC use depended mostly on aneurysm size. IR did not influence the surgical outcome, as well as TC use, if the occlusion was shorter than 8-10 min.

ABSTRACTIntroductionTransradial angiography (TRA) has received considerable attention in the field of neurointervention owing to its advantages over transfemoral approaches. However, the difficulty of left internal carotid artery (ICA) catheterization under certain anatomical conditions of the aortic arch and its branches is a limitation of TRA. This study aimed to investigate the anatomical predictors of successful catheterization of the left ICA in TRA.Materials and MethodsFrom January 2020 to October 2020, 640 patients underwent TRA at a single institute. Among them, 263 consecutive patients who were evaluated by contrast-enhanced MRI before TRA were included in our study and assigned to success and failure groups, according to whether left ICA catheterization was possible or not. Anatomical predictors that may affect the success of left ICA catheterization in TRA were investigated for the purposes of our study.ResultsThe multivariable analysis included variables that demonstrated significant univariate associations with ICA catherization (P<0.0001). Variables included in the model were the type of aortic arch, height of right subclavian artery, turn-off angle of the left common carotid artery (CCA), distance between innominate artery to the left CCA, angulation of right subclavian artery, and angulation of the left CCA, which we identified as significant predictors of left ICA catheterization.ConclusionSuccess of left ICA catheterization in TRA was related to the vascular geometry of the aortic arch and its branches. Evaluating the anatomical predictors identified in this study using pre-procedure imaging may enhance the success rate of left ICA catheterization in TRA.

Supraclinoid Internal Carotid Artery

We report our experience with endovascular treatment and follow-up results of a ruptured blood blister-like aneurysm (BBA) in the supraclinoid internal carotid artery. We performed a retrospective review of ruptured blood blister-like aneurysm patients over a 30-month period. Seven patients (men/women, 2/5; mean age, 45.6 years) with ruptured BBAs were included from two different institutions. The angiographic findings, treatment strategies, and the clinical (modified Rankin Scale) and angiographic outcomes were retrospectively analyzed. All seven BBAs were located in the supraclinoid internal carotid artery. Four of them were ≥ 3 mm in largest diameter. Primary stent-assisted coiling was performed in six out of seven patients, and double stenting was done in one patient. In four patients, the coiling was augmented by overlapping stent insertion. Two patients experienced early re-hemorrhage, including one major fatal SAH. Complementary treatment was required in two patients, including coil embolization and covered-stent placement, respectively. Six of the seven BBAs showed complete or progressive occlusion at the time of late angiographic follow-up. The clinical midterm outcome was good (mRS scores, 0–1) in five patients. Stent-assisted coiling of a ruptured BBA is technically challenging but can be done with good midterm results. However, as early regrowth/re-rupture remains a problem, repeated, short-term angiographic follow-up is required so that additional treatment can be performed as needed.
