The role of preoperative transarterial embolization in spinal tumors. A large single-center experience.

Background Context: Patients with spinal tumors are often referred for preoperative angiography and embolization before surgical resection to minimize intraoperative bleeding.

Purpose: The purpose of the present study was to investigate the angiographic appearance of a variety of spinal tumors, assess the safety and efficacy of preoperative embolization in relation to the amount of intraoperative blood loss, and correlate intraoperative tumor histology with the degree of gadolinium enhancement on spinal magnetic resonance imaging (MRI) and tumor vascularity visualized during angiography.

Study Design/setting: Retrospective and single-institution cohort study.

The ectopic appendicolith from perforated appendicitis as a cause of tubo-ovarian abscess.

Acute appendicitis is a common surgical cause of abdominal pain in the pediatric population. History and physical examination are atypical in up to a third of patients. Known potential complications of untreated or delayed management of acute appendicitis include appendiceal perforation, periappendiceal abscess formation, peritonitis, bowel obstruction and rarely septic thrombosis of mesenteric vessels.
