We report the case of a 75 years old man submitted to traditional EVAR for infrarenal abdominal aortic aneurysm. He presented a late type II endoleak 6 months after operation, initially without sac enlargement. One year later, a CT scan control demonstred a sac expansion > 10 mm, also responsible of a secondary proximal type I endoleak. The patient was submitted to transarterial embolization of lumbar arteries through left internal iliac artery, followed by type I endoleak correction with a proximal cuff deployment...

Inferior vena cava (IVC) aneurysms are extremely rare. Patients can be asymptomatic, have thrombosis, rupture, or pulmonary embolism. Thrombosis of the IVC aneurysm may mimic a retroperitoneal tumor. Surgical treatment of abdominal venous aneurysms with thrombosis is warranted and is necessary for the management of intraoperative bleeding and thrombosis.

Herein, we describe a technique for stent-assisted coil embolization with a spring-shaped microcatheter in a patient with an M1 ultrawide-necked circumferential aneurysm in the middle cerebral artery (MCA). A 49-year-old man was referred for treatment of an incidentally detected M1 large-circumference aneurysm on magnetic resonance angiography. Subsequent digital subtraction angiography revealed an 18.2×16.5 mm ultrawide-necked circumferential aneurysm on the distal M1 portion of the left MCA, and we planned stent-assisted coil embolization using a spring-shaped microcatheter...

Background Patients with polycystic kidney disease have a higher prevalence of intracranial aneurysms and may progress to renal failure requiring transplantation. The endovascular treatment of intracranial aneurysms may improve prognosis, since rupture often causes premature death or disability, but the nephrotoxicity risk associated with contrast medium must be always considered in cases of renal impairment. Methods A 55-year-old female patient with polycystic kidney disease and grafted kidney associated with anterior communicant artery aneurysm was successfully treated by embolization...

Vein of Galen aneurysmal malformation is a congenital anomaly of the cerebral vasculature representing 30% of all paediatric vascular malformations. We conducted whole exome sequencing in 19 unrelated patients presenting this malformation and subsequently screened candidate genes in a cohort of 32 additional patients using either targeted exome or Sanger sequencing. In a cohort of 51 patients, we found five affected individuals with heterozygous mutations in EPHB4 including de novo frameshift (p.His191Alafs*32) or inherited deleterious splice or missense mutations predicted to be pathogenic by in silico tools...

Background and aims: Few studies discuss the prevalence of oral anticoagulation therapy (OAT) in clinical practice, despite their increasing use worldwide. In America, studies established that 20% to 80% of the patients with indication benefit from OAT. In Romania, there is no data regarding the utilization of oral anticoagulants. Thus, this study aims to determine the trends of OAT. Methods: We designed a cross-sectional study of the patients admitted to the Cardiology Department of the "Bagdasar-Arseni" Clinical Emergency Hospital, Bucharest, from the 1st of November 2016 until the 31st of January 2017...

BACKGROUND AND PURPOSE: Endovascular embolization of intracranial aneurysms with hydrogel-coated coils lowers the risk of major recurrence, but technical limitations (coil stiffness and time restriction for placement) have prevented their wider clinical use. We aimed to assess the efficacy of softer, second-generation hydrogel coils. METHODS: A randomized controlled trial was conducted at 22 centers in France and Germany. Patients aged 18 to 75 years with untreated ruptured or unruptured intracranial aneurysms measuring 4 to 12 mm in diameter were eligible and randomized (1:1 using a web-based system, stratified by rupture status) to coiling with either second-generation hydrogel coils or bare platinum coils...

BACKGROUND: The choice of appropriate antiplatelet therapy prior to the Pipeline Embolization Device (PED) placement is usually guided by platelet function testing such as light transmission aggregometry (LTA). In this study, we aimed to define the optimal threshold LTA value for clopidogrel responsiveness to predict the risk of post-procedural thromboembolic complications and to help guide appropriate antiplatelet regimen. MATERIALS AND METHODS: A prospectively maintained database at an academic neurosurgical center in the United States was retrospectively analyzed from 2014 to 2017 to identify patients with unruptured intracranial aneurysms treated with the PED...
