Endovascular therapy in intermittent claudication: Impact of IVUS guidance on treatment decisions.

Conservative therapy is favored over revascularization for patients with peripheral arterial disease (PAD) and intermittent claudication (IC) owing to the better long-term results. The adjunctive use of intravascular ultrasound (IVUS) significantly improves endovascular therapy. However, data on IVUS and IC is scarce.

The Value of Local Therapies in Advanced Adrenocortical Carcinoma.

International guidelines recommend local therapies (LTs) such as local thermal ablation (LTA; radiofrequency, microwave, cryoablation), transarterial (chemo)embolisation (TA(C)E), and transarterial radioembolisation (TARE) as therapeutic options for advanced adrenocortical carcinoma (ACC). However, the evidence for these recommendations is scarce. We retrospectively analysed patients receiving LTs for advanced ACC.

Monitoring Dual-Cancer Treatment in a Patient With Prostate and Hepatocellular Carcinoma Using Prostate-Specific Membrane Antigen-Directed PET/CT.

We report on a 70-year-old man affected with prostate carcinoma (PC) scheduled for prostate-specific membrane antigen (PSMA) PET/CT using 18 F-PSMA1007. Because of uptake in the liver and corresponding findings on magnetic resonance, diagnosis of hepatocellular carcinoma (HCC, G1) was established. The patient was then scheduled for antihormonal treatment for PC and locoregional therapy due to HCC.

Current Evidence on Local Therapies in Advanced Adrenocortical Carcinoma.

International guidelines emphasise the role of local therapies (LT) for the treatment of advanced adrenocortical carcinoma (ACC). However, large studies are lacking in this field. Therefore, we performed a review of the literature to synthesise current evidence and develop clinical guidance.

[Indications and techniques for endovascular revascularization of visceral arteries in mesenteric ischemia].

Endovascular revascularization of visceral arteries is an important cornerstone of an interdisciplinary treatment concept for both acute and chronic forms of mesenteric ischemia. The advantages lie in the minimally invasive procedure and the speed of restoration of perfusion. This article provides an overview of the indications, techniques and current state of the clinical literature with respect to endovascular revascularization.
