Imaging appearance on CT post laparoscopic Roux-en-Y gastric bypass using bioabsorbable prosthesis with fibrin glue fixation to prevent a Petersen's space hernia.

Imaging post bariatric surgery is becoming more common over the past decade due to increasing incidence of obesity in the population and subsequent treatment. In recent years, the use of topical haemostatic agents and bioabsorbable prostheses has increased leading to higher likelihood of encountering these agents on post-operative imaging. Imaging in the post-operative period is occasionally performed to assess for complications such as obstruction, leak and abscess formation.

Ruptured gastric artery aneurysms: two cases and emergency imaging findings.

A ruptured gastric artery aneurysm is a rare but important possible cause of massive intra-abdominal or gastrointestinal haemorrhage, and carries a high risk of mortality. Although aneurysms of the gastric arteries are uncommon, emergency radiologists and clinicians should be familiar with the clinical presentation, imaging findings and pathophysiology. We present two cases of massive intra-abdominal haemorrhage and haemodynamic shock secondary to acute rupture of previously occult gastric artery aneurysm and review the relevant anatomy, imaging findings and pathophysiology of gastric and other visceral artery aneurysms.

Transfalciform greater omental herniation.

Internal herniae are rare, those involving the falciform ligament even rarer. To the best of our knowledge, there have been approximately 20 cases of herniae involving the falciform ligament previously reported. Of these cases, only one previously reported case involves herniation of the greater omentum through the falciform ligament.

Look away: arterial and venous intravascular embolisation following shotgun injury.

We describe two cases of intravascular embolization of shotgun pellets found distant to the entry site of penetrating firearm injury. The cases demonstrate antegrade embolization of a shotgun pellet from neck to right middle cerebral artery, and antegrade followed by retrograde venous embolization through the left lower limb to pelvis. Radiologists and Trauma Physicians should be aware that post shotgun injury, the likelihood of an embolised shot pellet is increased compared to other types of firearm missile injury, and should therefore search away from the site of injury to find such missiles.

Measurement of uterine fibroid volume: a comparative accuracy and validation of methods study.

Objective: A range of measurement techniques have been described which may be used to calculate uterine fibroid volume. A commonly-reported method involves application of a formula for the volume of an ellipsoid sphere to three orthogonal axes of a fibroid as measured on cross-sectional images. We aimed to compare this method and a second method, that of software-computed parallel planimetric uterine fibroid computation on MRI images, to a gold standard: the volume of objects measured by water displacement.

Diagnostic Accuracy of Imaging Modalities in the Evaluation of Vascular Invasion in Pancreatic Adenocarcinoma: A Meta-Analysis.

Background: The extent of vascular invasion is a key factor determining the resectability of non-metastatic pancreatic adenocarcinoma. The purpose of this study is to determine the diagnostic accuracy of computed tomography (CT), endoscopic ultrasound (EUS), and magnetic resonance imaging (MRI) in the pre-operative evaluation of vascular invasion in pancreatic adenocarcinoma, with surgery as the reference standard.

Methods: A search of the MEDLINE database for relevant articles in the English language published between January 2000 and February 2009 was performed.

Safety and treatment volumes achieved following new developments of the magnetic resonance-guided focused ultrasound system in the treatment of uterine fibroids: a cohort study.

Background: This research investigates whether modifications to the magnetic resonance-guided focused ultrasound ablation of uterine fibroid (MRgFUS) system used resulted in improved treatment volumes of uterine fibroids, while maintaining safety.

Methods: This study is a prospective cohort analysis of 34 women undergoing the ExAblate 2100 MRgFUS treatment for their uterine fibroids.

Results: The percentage of non-perfused volume (NPV) achieved with the ExAblate 2100 system was 54.

Concurrent thrombosed aneurysmal sciatic artery and anomalous aortic arch.

A persistent sciatic artery is a rare developmental anomaly which may predispose to a range of vascular complications. We report a 60-year-old woman presenting with right lower limb ischemia. Computed tomography angiography revealed an aneurysmal right-sided sciatic artery occluded by thrombus.

Case report of idiopathic pulmonary haemosiderosis in a child with recurrent chest infections.

Idiopathic pulmonary haemosiderosis (IPH) is a rare condition that usually presents as a triad of haemoptysis, iron deficiency anaemia and pulmonary infiltrates. We report a case of IPH diagnosed in a 7 year old boy who had recurrent hospital admissions with severe chest infections and haemoptysis from his first few months of life. He was found to have microcytic hypochromic anaemia, diffuse infiltrate shadowing on his chest X-ray (CXR) and ground-glass opacification on his computed tomogram (CT).

Opinion: integration of diagnostic and management perspectives for placenta accreta.

The 2007 New South Wales/Queensland Royal Australian and New Zealand College of Obstetricians and Gynaecologists Annual Scientific Meeting convened a panel to discuss multidisciplinary perspectives on the management of placenta accreta, percreta or increta. While it was anticipated that this panel would stimulate discussion, the cohesion between the approaches was underestimated. This document represents an integration of the perspectives of the invited speakers at this presentation, with backgrounds in maternal-fetal medicine, gynaecological oncology, radiology and general obstetrics and gynaecology.

Stent-assisted coil embolization of a wide-necked renal artery aneurysm.

We present a case of stent-assisted coil embolization of a wide-necked renal artery aneurysm performed at our institution. The technique involved a stent being delivered over the neck of the aneurysm. Subsequently a catheter was placed into the aneurysm through the stent mesh and the aneurysm was then filled with detachable coils.
