CTA measurements of acute lower gastrointestinal bleeding size predict subsequent positive catheter angiography

AbstractPurposeThe purpose of this study was to determine whether the measured size of active gastrointestinal hemorrhage was useful in predicting subsequent positive findings at catheter angiography.Materials and methodsThis was a single-institution retrospective study consisting of 32 patients with computed tomography angiography (CTA) positive for gastrointestinal bleeding who went on to receive catheter angiography. Each CTA was reviewed, with axial measurements of the anterior –posterior and transverse dimensions of the largest foci of hemorrhage recorded. Volumetric analysis was used to measure the volume of hemorrhage. These measurements were performed for both the arterial and portal venous phases. Additionally, the interval growth between the arterial and portal ven ous phase was also calculated.ResultsThere was a statistically significant difference in the absolute size of the maximum transverse dimension on portal venous phase imaging (mean  = 19.8 mm,p

AbstractAfter the introduction and the quick improvement of multidetector computed tomography technology, computed tomographic angiography (CTA) has become the imaging examination of choice for the first assessment of patients affected by lower extremities acute disorders. The widespread availability of CT equipment, the high temporal and spatial resolution with post-processing reformation possibilities represent the main advantages of this technique, which can reliably identify different findings related to arterial vessel pathology, such as occlusion, dissection, active bleeding, and pseudoaneurysm. Radiologists should k...

This study investigated whether paranasal sinus (PNS) CT could provide information for predicting EA bleeding without angiography in patients with refractory epistaxis requiring ESPAL.MethodsForty-seven patients, who were surgically treated [with ESPAL or EA ligation (EAL)] for refractory epistaxis from March 2010 to June 2019, were retrospectively analyzed. A positive PNS CT finding for EA bleeding was defined as the presence of soft tissue densities having continuity with the EA pathway, accompanied by a partially deficient surrounding bony canal. These findings as well as soft tissue densities in each paranasal sinus we...

CONCLUSION: Infected pseudoaneurysms in IVDAs pose a unique challenge to vascular surgeons. We found that simple ligation and debridement was a safe and effective option for such patients. PMID: 32147737 [PubMed - as supplied by publisher]

INTRODUCTION Admission computed tomography (CT) is a widely used diagnostic tool for patients with pelvic fractures. In this pilot study, we hypothesized that pelvic hematoma volumes derived using a rapid automated deep learning-based quantitative visualization and measurement algorithm predict interventions and outcomes including (a) need for angioembolization (AE), pelvic packing (PP), or massive transfusion (MT), and (b) in-hospital mortality. METHODS We performed a single-institution retrospective analysis of 253 patients with bleeding pelvic fractures who underwent admission abdominopelvic trauma CT between 2008 ...

Multidetector computed tomography angiography (CTA) plays an essential role in diagnosis and localization of lower gastrointestinal bleeding (LGIB) through detection of arterial extravasation for subsequent management with transcatheter angiography (TA) and embolization. However, the inability to reproduce arterial extravasation on transcatheter angiography precludes effective and safe embolization for treatment of LGIB. The purpose of this study is to examine whether the time interval (TI) between CTA and transcatheter angiography influences the reproducibility of arterial extravasation on subsequent angiography.

Abstract BACKGROUND AND OBJECTIVES: Bedside sonographic duplex technique (SDT) may be used as an adjunct to cranial computed tomography (CCT) to monitor brain-injured patients after decompressive craniectomy (DC). The present study aimed to assess the value of SDT in repeated measurements of ventricle dimensions in patients after DC by comparing both techniques. MATERIALS AND METHODS: Retrospective assessment of 20 consecutive patients after DC for refractory intracranial pressure (ICP) increase following subarachnoid hemorrhage (SAH), bleeding and trauma which were examined by SDT and CCT in the context of r...
