Pseudoaneurysm after High-Grade Penetrating Solid Organ Injury and Utility of Delayed CT Angiography.

Background: Leaving an injured solid organ in situ allows preservation of structure function but invites complications from the damaged parenchyma, including pseudoaneurysms (PSAs). Empiric PSA screening after solid organ injury is not yet established, particularly following penetrating trauma. The study objective was definition of delayed CT angiography (dCTA) yield in triggering intervention for PSA after penetrating solid organ injury.

Recent trends in the management of isolated high-grade splenic injuries: A nationwide analysis.

Background: The feasibility of nonoperative management for high-grade blunt splenic injuries (BSIs) has been suggested in recent studies. The purpose of this study was to assess nationwide trends in the management of isolated high-grade BSIs. We hypothesized that isolated high-grade BSIs are more frequently being managed nonoperatively.

Pseudoaneurysms after high-grade blunt solid organ injury and the utility of delayed computed tomography angiography.

Purpose: Pseudoaneurysms (PSA) can occur following high-grade solid organ injury. PSA natural history is unclear but risk for spontaneous rupture and exsanguination exist. The yield of delayed CT Angiography (dCTA) for PSA diagnosis is not well delineated and optimal timing is undefined.

Pseudoaneurysm Screening after Pediatric High Grade Solid Organ Injury.

Background: High grade solid organ injuries carry risk of complications, including pseudoaneurysms (PSA). The optimal approach to PSA screening among pediatric patients is unknown and may include delayed Computed Tomography Angiography (dCTA) and/or contrast-enhanced ultrasound (CEUS). This study endeavored to define dCTA/CEUS yield in PSA diagnosis after pediatric high grade solid organ injury.

Rectal arterio-venous malformation (AVM) with bleeding of an internal hemorrhoid.

A 38-year-old male with no past history of illnesses visited the out-patient clinic of Nerima Hikarigaoka Hospital complaining of dizziness and persistent anal bleeding. There was a significant anemia on a blood test and colonoscopy showed a thrombus in a markedly swollen internal hemorrhoid. Contrast-enhanced computed tomography (CT) showed a poorly demarcated area with early face enhancement on the right side of the rectum and anal canal.
