A novel, highly-trackable, bevel-tipped Zoom 35 catheter can be used as an aspiration catheter for DVO thrombectomy.
Methods: This is a retrospective, single-arm, multi-institutional observational study evaluating the efficacy and safety of aspiration thrombectomy for DVO using the Zoom 35 catheter.
Cerebral venous sinus thrombosis (CVST) is a rare type of stroke indicated by the formation of blood clots within the dural venous sinuses. These are large venous conduits that are situated between the 2 layers of the dura mater which are responsible for draining blood from the brain and returning it to the systemic circulation. Cortical venous thrombosis refers to the blockage of veins on the brain's cortical surface.

Objectives: Multiple prior studies have shown a relationship between COVID-19 and strokes; further, COVID-19 has been shown to influence both time-to-thrombectomy and overall thrombectomy rates. Using large-scale, recently released national data, we assessed the association between COVID-19 diagnosis and patient outcomes following mechanical thrombectomy.
Materials And Methods: Patients in this study were identified from the 2020 National Inpatient Sample.
Objective: Pediatric isolated linear skull fractures commonly result from head trauma and rarely require surgery, yet patients are often admitted to the hospital-a costly care plan. In this study, the authors utilized a national database to investigate trends in admission for skull fractures across the United States.
Methods: Children younger than 18 years with isolated linear skull fracture, according to ICD-9 diagnosis codes in the Kids' Inpatient Database of the Healthcare and Utilization Project (HCUP), who presented between 2003 and 2016 were included.
Introduction: The purpose of this study was to identify predictors of increased cost and postoperative length-of-stay (LOS) following intrathecal baclofen pump (ITBP) placement.
Methods: Patients were derived from the 2009/2012 kids' inpatient database. Inclusion criteria were selected for patients with ICD-9 codes 343.
Objective: The aim of this study was to examine perioperative medication patterns surrounding major amputation surgeries.
