The objective of our study was to provide a comparative assessment of previously reported magnetic resonance imaging (MRI) parameters in primary and secondary pseudotumor cerebri (PTC) patients, to examine their diagnostic contribution, and to evaluate their association with symptoms, neuro-ophthalmological findings, laboratory results, and cerebrospinal fluid characteristics. Twenty-eight consecutive patients with PTC were included in the study. Age-and sex-matched 20 individuals with normal neurologic examination served as the control group. Modified Dandy Criteria were used for the diagnosis of PTC. Orbital and cranial MRI and MR venography of all patients and controls were assessed by three radiologists. According to our study, posterior flattening of the globe (64% sensitive, 100% specific), optic nerve sheath distention (46% sensitive, 100% specific), vertical tortuosity of the optic nerve (30% sensitive, 95% specific), and partial empty sella (43% sensitive, 100% specific) emerged as particularly valuable markers for a diagnosis of PTC.

Objectives To evaluate the primary patency rate at three years for the infra-aortic peripheral arterial pathologies treated with polytetrafluoroethylene-covered stent-grafts. Methods Patients treated with self-expandable polytetrafluoroethylene-covered stent-grafts for infra-aortic peripheral arterial aneurysms, pseudo-aneurysms, and arterio-venous fistulas were evaluated retrospectively. A total of 48 patients (35 male, 13 female; mean age: 53.8 ± 13.5) were included with 29.0 ± 16.5 months (median 27, range 4–70) mean follow-up period. The primary objective was to determine the primary patency rate at three years. The secondary objectives were to compare type and localization of pathology, and length and diameter of the stent-grafts with primary patency rate. Kaplan–Meier test was used as the main statistical method. Results Overall mean primary patency rate at three years was 77.10%. Polytetrafluoroethylene-covered stent-graft implantation in aneurysms had worse primary patency rate than pseudo-aneurysms and arterio-venous fistulas (66.6%, P = 0.03; 76.9%, P = 0.03; 88.2%, P = 0.01, respectively). Stent-graft location, length, and diameter are not associated with primary patency rate ( P > 0.05) but stent diameter is associated with better primary assisted and secondary patency rates ( P < 0.05). Conclusions Pathology of the lesion is associated with the long-term primary patency rate of polytetrafluoroethylene-covered stent-grafts but not the stent-graft location, length, or diameter. Stent diameter is associated with primary assisted and secondary patency rates.

Background and Objective: An intracranial aneurysm (IA) is a life-threatening condition and endovascular treatment (EVT) is a demanding procedure, especially in IAs with an unfavorable anatomy. The aim of this study was to investigate the safety and efficacy of balloon-assisted microwire navigation and microcatheter positioning in the EVT of IAs with challenging anatomies. Materials and Methods: This retrospective study included patients that underwent balloon-assisted microwire navigation and microcatheter positioning in the EVT of IAs between September 2016 and January 2019. All EVT procedures and data collection were performed by the same two neurointerventional radiologists. Technical success and complication rates, safety, and efficiency of the balloon manipulation method were evaluated. Statistical software was used to analyze the basic descriptive data of the patients and aneurysms. Results: This study included 14 patients. The microwire navigation of the target artery with balloon manipulation was used in 4 aneurysms of 4 patients. Microcatheter positioning with balloon manipulation was used in 10 aneurysms of 10 patients. There was no complication caused by the balloon manipulation technique. The technical success rate was 100%. Conclusion: In the EVT of IAs with challenging anatomies, the presented technique is a safe and effective option without additional complications, especially in the target artery with an acute angle and in small aneurysms.
