Accuracy of dual-bolus CT in the diagnosis of active arterial bleeding in adult pelvic trauma.

Introduction: A single-phase dual-bolus CT (DB-CT) simultaneously opacifies both arterial and venous systems and can be utilised in the trauma setting to aid in the diagnosis of active bleeding while also allowing for optimal assessment of the abdominal and pelvic viscera. Active bleeding can be venous or arterial, the latter being amenable to angiography and potentially embolisation. We aimed to establish the accuracy of single-phase DB-CT vs commonly performed portal venous CT (PV-CT) in the diagnosis of active bleeding when compared to formal digital subtraction angiography as the gold standard.

Prolonged balloon tamponade in the initial management of inferior vena cava injury following complicated filter retrieval, without the need for surgery.

Advanced techniques have been described to remove embedded inferior vena cava (IVC) filters including the loop snare and modified loop snare (Hangman) techniques. Retrieval of embedded filters have been associated with higher rates of complications including IVC injury and stenosis. We report two challenging embedded retrievals complicated by IVC injury and haemorrhage.
