Improving outcomes in atherosclerotic renovascular disease: importance of clinical presentation and multi-disciplinary review.

Background And Objectives: Atherosclerotic renal artery stenosis may cause hypertension, chronic kidney disease and heart failure, but large randomized control trials to date have shown no major additional benefit of renal revascularization over optimal medical management. However, these trials did not consider outcomes specifically in relation to clinical presentations. Given that atherosclerotic renal artery stenosis is a heterogenous condition, measures of success likely differ according to the clinical presentation.

Managing acute presentations of atheromatous renal artery stenosis.

Background: Atherosclerotic renovascular disease (ARVD) often follows an asymptomatic chronic course which may be undetected for many years. However, there are certain critical acute presentations associated with ARVD and these require a high index of suspicion for underlying high-grade RAS (renal artery stenosis) to improve patient outcomes. These acute presentations, which include decompensated heart failure syndromes, accelerated hypertension, rapidly declining renal function, and acute kidney injury (AKI), are usually associated with bilateral high-grade RAS (> 70% stenosis), or high-grade RAS in a solitary functioning kidney in which case the contralateral kidney is supplied by a vessel demonstrating renal artery occlusion (RAO).

Radiological initial treatment of vascular catastrophes in pancreas transplantation: Review of current literature.

Background: Arterio-enteric fistula (AEF) is a rare but potentially devastating complication of solid organ pancreatic transplantation. Traditional management has been to remove the pancreas-duodenum allograft and control the vascular defect. Interventional radiological (IR) techniques present a new method of managing AEF related haemorrhage without re-operation and the potential to preserve graft function.

Endovascular Hepatic Artery Stents in the Modern Management of Postpancreatectomy Hemorrhage.

Background: Postoperative hemorrhage is a potentially lethal complication of pancreatoduodenectomy. This study reports on the use of endovascular hepatic artery stents in the management of postpancreatectomy hemorrhage.

Methods: This is a retrospective analysis of a prospectively maintained, consecutive dataset of 440 patients undergoing pancreatoduodenectomy over 68 months.

The Impact of COVID-19 on Interventional Radiology Services in the UK.

Introduction: The coronavirus disease 2019 (COVID-19) has created unprecedented challenges on the healthcare system. The aim of this multi-centre study was to measure the impact of COVID-19 on IR services in the UK.

Material And Methods: Retrospective cross-sectional study of IR practice in six UK centres during the COVID-19 pandemic was carried out.

Acute hypersensitivity reaction to femoral drug-coated balloons.

We describe a case of an acute hypersensitivity reaction to a paclitaxel-coated balloon used in the peripheral arterial circulation. Clinicians using these products should be aware of this potential risk.
