Background: Due to anatomic features, including wide necks and incorporation of important branches, endovascular coiling of middle cerebral artery (MCA) aneurysms has proved challenging. Stent assisted embolization may increase the likelihood of successful treatment.
Methods: Consecutive patients undergoing stent assisted coil embolization utilizing the Neuroform stent from 2004 to 2009 were identified by hospital billing records. Procedural and clinical information-including procedure related mortality and morbidity and long term outcomes-were then obtained by retrospective chart review.
Results: Treatment was successful in 22/23 (96%) patients. Median age was 61 years and 16/22 (73%) were women. Aneurysm size was: <5 mm in 5/22 (23%); 5-9 mm in 14/22 (64%); and ≥10 mm in 3/22 (14%) patients. There were four periprocedural complications (including one stroke and one intraprocedural rupture), none associated with neurological dysfunction. Angiographic follow-up was available in 18/22 (82%) and clinical follow-up in 19/22 (86%) patients, both at a median of 1 year (mean 1.2 years) after coiling. Aneurysm occlusion was complete in 12/18 (67%), a neck remnant was present in 3/18 (17%) and persistent aneurysmal filling was present in 3/18 (17%) patients, requiring retreatment in 1/18 (6%) patient. In-stent stenosis of 50%, which was asymptomatic, occurred in 1/18 (6%) patient. No subarachnoid hemorrhages and no ischemic events related to the procedure were observed during follow-up.
Conclusion: In this small series, the technical success rate was 96%, there were no transient or permanent neurological complications and complete aneurysmal occlusion was achieved in two-thirds of treated aneurysms on follow-up angiography. These results suggest that in appropriately selected patients, stent assisted coil embolization of MCA aneurysms can be performed with a high degree of safety and acceptable durability.

Introduction: Since the mid-1900s, techniques in the repair of aortic arch and thoracoabdominal aortic pathologies have drastically evolved. Open aortic surgical repair was once the sole option for both simple and complex aneurysmal degeneration. Today, a number of minimally invasive and hybrid approaches are now available to assist both the surgeon and patient in tackling this challenging problem.

Robot-assisted pancreaticobiliary junction resection is a surgical technique employed to treat benign duodenal tumors. The procedure involves several key steps: making a longitudinal incision in the duodenum, excising the tumor at the pancreaticobiliary junction, inserting a biliary stent, connecting the biliary and duodenal mucosa, and suturing the duodenal incision during phase I. The robotic system enhances visibility, facilitates precise operations, minimizes duodenal traction injuries to the duodenum and surgical trauma, ensures accurate suture and fixation of bile duct stents, connects the bile duct and duodenal mucosa and reduces postoperative recovery time.

Background: Transverse sinus stenosis (TSS) and sigmoid sinus wall anomalies (SSWAs) are the most common causes of pulsatile tinnitus (PT). While these conditions may co-occur, they usually require different management approaches. This study aims to evaluate whether TSS stenting alone, without targeted treatment of SSWAs, is sufficient to resolve PT in patients presenting with PT, TSS, and SSWAs.

Objective: Emergent complex abdominal aortic diseases are challenging to treat. During in situ laser fenestration (ISLF), aortic branches are covered and flow is restored with in situ fenestration of the stent graft, with promising midterm results. This study aimed to expand on the limited body of knowledge of midterm outcomes of ISLF in renovisceral aortic pathology in a multicentre setting.

Background: The indications for pediatric airway endoscopy are expanding and a variety of therapeutic interventions are feasible for central airway obstruction (CAO) and other central airway pathologies, apart from foreign body removal.
Methods: In this retrospective chart review from four centers, we describe the indications, procedures, outcomes, and complications of therapeutic bronchoscopic interventions in children for non foreign-body removal indications.
Results: A total of 72 children (mean age:140 [60.
