Pseudoaneurysm of a Bronchial Artery: An Unusual Cause of Chest Pain

We report a case of a bronchial artery pseudoaneurysm presenting as acute retrosternal pain. We want to discuss and to announce the extremely rare finding of a bronchial artery pseudoaneurysm. Bronchial artery aneurysms and pseudoaneurysms are uncommon; however, missing this diagnosis is associated with significant morbidity and mortality. When suspecting this pathology urgent CT angiography and selective angiography (DSA) are crucial. Urgent treatment with transarterial embolization is preferred

Therapeutic Intranodal Lymphangiography for Refractory Chylous Ascites Complicating Acute Necrotic Pancreatitis

Chylous ascites is a rare complication of acute pancreatitis. However, the incidence of intraperitoneal chyle leakage related to severe pancreatitis may be much higher. This is probably the result of direct damage to the cisterna chyli or its tributaries by pancreatic enzymes. In this case, conservative treatment failed to resolve the chyle leak. For the first time, to our knowledge, ultrasound guided therapeutic intranodal lymphangiography was shown to be a successful, minimally invasive treatment option in chylous ascites complicating acute necrotic pancreatitis.status: publishe

Flat detector CT with cerebral pooled blood volume perfusion in the angiography suite : from diagnostics to treatment monitoring

C-arm flat-panel detector computed tomographic (CT) imaging in the angiography suite increasingly plays an important part during interventional neuroradiological procedures. In addition to conventional angiographic imaging of blood vessels, flat detector CT (FD CT) imaging allows simultaneous 3D visualization of parenchymal and vascular structures of the brain. Next to imaging of anatomical structures, it is also possible to perform FD CT perfusion imaging of the brain by means of cerebral blood volume (CBV) or pooled blood volume (PBV) mapping during steady state contrast administration. This enables more adequate decision making during interventional neuroradiological procedures, based on real-time insights into brain perfusion on the spot, obviating time consuming and often difficult transportation of the (anesthetized) patient to conventional cross-sectional imaging modalities. In this paper we review the literature about the nature of FD CT PBV mapping in patients and demonstrate its current use for diagnosis and treatment monitoring in interventional neuroradiology
