Is Size All That Matters? New Predictors of Complications and Bleeding in Renal Angiomyolipoma.

Purpose: Renal angiomyolipoma (AML) is the most common benign renal tumor. Whilst generally asymptomatic, they can cause life-threatening bleeding. Selective angioembolization (SAE) may be used to treat large symptomatic and asymptomatic AMLs.

Endovascular management of recurrent hemarthrosis of the knee: a case series.

Background: Recurrent hemarthrosis of the knee is an uncommon but potentially debilitating occurrence with multiple etiologies, including previous total knee replacement. The purpose of this study is to present data of a group of patients undergoing angiography and embolization for recurrent hemarthrosis of the knee. Patient characteristics, angiographic findings, safety and efficacy of the procedure are reported.

Establishing a Platform for Interest and Education in Interventional Radiology Amongst Radiology Trainees.

Purpose: Over recent times, procedural Radiologists have begun to establish themselves as the distinct subspecialty of Interventional Radiology (IR). The Interventional Radiology Society of Australasia (IRSA) was established in 1982 to share collaborative ideas, encourage research, and promote education. IRSA developed a weekend registrar workshop attended by Radiology Registrars from Australia and New Zealand.

Challenges in chemotherapy delivery: comparison of standard chemotherapy delivery to locoregional vascular mass fluid transfer.

Standard intravenous chemotherapy delivery to neoplasms relies on simple diffusion gradients from the intravascular to the interstitial space. Systemic perfusion creates untoward effects on normal tissue limiting both concentration and exposure times. Regional intra-arterial therapy is limited by drug recirculation and vascular isolation repeatability and does not address the interstitial microenvironment.

Safety and Feasibility of Repeatable Hepatic Vascular Isolation Chemotherapy: A Pilot Study.

Background: The authors herein describe a novel method of repeatable hepatic isolation using an implantable access system allowing simultaneous control of hepatic arterial and portal flows by multiple endovascular catheters.

Purpose: The aim of this study was to assess the feasibility and safety of the system and to compress standard intravenous chemotherapy into 4 weeks of targeted intra-arterial delivery.

Methods: An arterial access system was implanted to the axillary artery via an anastomosis.

Novel Treatment of an Enlarging Internal Iliac Artery Aneurysm in Association with a Type 2 Endoleak via Percutaneous Embolisation of the Superior Gluteal Artery through a Posterior Approach.

Internal iliac artery (IIA) aneurysms, while rare, carry a significant risk of mortality if they rupture. Endovascular intervention is now the preferred method of treatment for IIAs; however, due to technical considerations, this is not always feasible. We report a case of a patient who developed an enlarging IIA aneurysm in association with a type 2 endoleak supplied by multiple feeding arteries where conventional endovascular treatment was not possible.

Entrapment neuropathy of the ulnar nerve by a constriction band: the role of MRI.

The diagnosis of ulnar nerve entrapment at the elbow has relied primarily on clinical and electrodiagnostic findings. Magnetic resonance imaging (MRI) has been used in the evaluation of peripheral nerve entrapment disorders to document signal and configurational changes in nerves. In this case report we review the MRI and operative findings of a rare constriction band causing ulnar nerve compression at the elbow.
