BACKGROUND AND PURPOSE: GEL THE NEC (GTN) was a multicenter prospective registry developed to assess the safety and efficacy of HydroSoft coils in treating intracranial aneurysms. We compared the angiographic and clinical outcomes of aneurysms treated with balloon assisted coil embolization (BACE) versus unassisted coil embolization (CE) in the ruptured aneurysm cohort. MATERIALS AND METHODS: GTN was performed at 27 centers in five countries. Patients aged 21-90 years with a ruptured aneurysm 3-15 mm in size were eligible for enrollment...

Although endovascular therapy has been proven safe and has become in many centers the primary method of treatment for intracranial aneurysms, the long-term durability of endovascular embolization remains a concern; at least for some aneurysms despite initial good result. While healing after clipping relies on mechanical occlusion, restoration after endovascular occlusion mainly requires the induction of a biological response. Healing after embolization depends on the growth of new tissue over the thrombus formed by the embolization material, or alternatively, on the organization of thrombus into fibrous tissue...

To evaluate whether the efficacy and safety of embolization of the aneurysmal neck were better than those of embolization of the entire aneurysm. Previous studies found that embolization of the aneurysmal neck can be used for treating ruptured intracranial aneurysm with bleb formation.In all, 163 patients with ruptured aneurysms with bleb formation who underwent endovascular embolization at the Shanghai Municipal Jing'an District Central Hospital from January 2014 to August 2015 were divided into the embolization of aneurysmal neck group (neck group; 87 cases) and embolization of entire aneurysm group (aneurysm group; 76 cases)...

Pancreaticoduodenal artery aneurysms (PDA) are rare visceral aneurysms. Celiac trunk stenosis represents a common attributable aetiology for those aneurysms. Therefore, an alternative treatment approach, which differs from those isolated aneurysms, is recommended. We hereby present a 77-year-old male patient who was admitted with sudden onset of severe abdominal pain and significant drop in haemoglobin, occurring within a 24-hour interval. Contrast-enhanced computed tomography revealed a ruptured visceral aneurysm arising from the anterior branch of the inferior pancreaticoduodenal artery...

In this case report, we describe an unusual episode of bilateral submassive pulmonary embolism (PE) caused by a popliteal vein aneurysm (PVA). The development of PE stems from many risk factors including obesity (BMI³ 30 kg/m2), hypertension, cigarette smoking (greater than 25 cigarettes per day), increasing age, surgery, immobility, malignancy, and inherited thrombophilia. A PVA is a rare but significant cause of PE. A 28-year-old male presented to the emergency department with progressive shortness of breath...

PURPOSE: To demonstrate a proof of concept of magnetic resonance (MR) coagulation, in which MR imaging scanner-induced radiofrequency (RF) heating at the end of an intracatheter long wire heats and coagulates a protein solution to effect a vascular repair by embolization. MATERIALS AND METHODS: MR coagulation was simulated by finite-element modeling of electromagnetic fields and specific absorption rate (SAR) in a phantom. A glass phantom consisting of a spherical cavity joined to the side of a tube was incorporated into a flow system to simulate an aneurysm and flowing blood with velocities of 0-1...

PURPOSE: Incompletely occluded aneurysms after coil embolization are subject to recanalization but occasionally progress to a totally occluded state. Deployed stents may actually promote thrombosis of coiled aneurysms. We evaluated outcomes of small aneurysms (<10 mm) wherein saccular filling with contrast medium was evident after stent-assisted coiling, assessing factors implicated in subsequent progressive occlusion. METHODS: Between September 2012 and June 2016, a total of 463 intracranial aneurysms were treated by stent-assisted coil embolization...

Visceral artery aneurysms (VAAs) are a rare entity. Within this subset of aneurysms, gastroduodenal artery (GDA) aneurysms represent an even more rare occurrence. We present a case report of treating GDA aneurysm on semi-elective basis followed by literature review of the clinical presentation and mainstream treatment modalities. GO is a 65-year-old male, with 6-month history of recurrent epigastric pain. He was found to have acute pancreatitis and an adjacent 3.5-cm GDA aneurysm. After conservative treatment of pancreatitis, the aneurysm was treated with coil embolization of the sac and GDA...

Cervical carotid aneurysms are rare, and surgical treatment should be planned for each patient. The authors report 9 cases of cervical carotid aneurysm in 9 patients(mean age, 53.7 years;5 men)who were treated surgically between 2005 and 2014. The aneurysm was located in the internal carotid artery in 6 patients, the common carotid artery in 2 patients, and the carotid bifurcation in 1 patient. Four aneurysms were recurrences after a previous endovascular intervention(parent artery coil embolization, covered stent placement, or stent with coil embolization)...

Ruptured intracranial aneurysms are extremely rare in infants. The optimal treatment strategy is not well established. Both microsurgical and endovascular techniques and strategies have been tried, and in the literature there is a significant variability in outcome. The authors report the presentation and successful endovascular treatment of a large, ruptured, middle cerebral artery bifurcation aneurysm in a 5-week-old girl, one of only a few reported in the literature. Clinical and radiological findings at follow-up are also presented...

Intracranial saccular aneurysm treatment using endovascular embolization devices are limited by aneurysm recurrence that can lead to aneurysm rupture. A shape memory polymer (SMP) foam-coated coil (FCC) embolization device was designed to increase packing density and improve tissue healing compared to current commercial devices. FCC devices were fabricated and tested using in vitro models to assess feasibility for clinical treatment of intracranial saccular aneurysms. FCC devices demonstrated smooth delivery through tortuous pathways similar to control devices as well as greater than 10 min working time for clinical repositioning during deployment...

Angiomyolipoma (AML) is a rare benign tumour of kidney which demonstrates rapid growth during pregnancy due to hormonal stimulation, leading to rupture. Majority of reported ruptured AMLs are in third trimester. We report a case of ruptured angiomyolipoma at 10th week of gestation, the earliest rupture known in singleton pregnancy. The AML had pseudo-aneurysm formation with extra-tumoural rupture during pregnancy, a finding never reported in literature yet. The patient had active bleeding with expanding peri-nephric haematoma during initial two days of conservative management...

We describe the clinical case of a patient experiencing severe gross hematuria causing clotting in the renal pelvis, after undergoing a kidney biopsy.The ecocolordopper and CT angiography performed did not reveal the cause of hematuria.The kidney arteriography allowed the diagnosis, revealing an arteriovenous fistula responsible for bleeding together with a small false aneurysm in the lower pole of the biopsied kidney. Both lesions were successfully treated with superselective embolization with microcoils. We discuss about the diagnostic and therapeutic approach of these rare post-biopsy complications briefly focusing on the technical aspects and on possible risks that the transcatheter embolotherapy may result...

Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic or absent radii, and first metacarpal to hypoplastic ulna and carpal bone anomalies. Cardiac involvement ranges from asymptomatic conduction disturbances to multiple structural defects...
