The position of transarterial chemoembolization with drug-eluting beads and yttrium-90 transarterial radioembolization in patients with hepatocellular carcinoma: Consensus statements from a Delphi-method expert panel in Turkey.

Purpose: Clinical studies conducted in different geographic regions using different methods to compare transarterial chemoembolization (TACE) and transarterial radioembolization (TARE) have demonstrated discordant results. Meta-analyses in this field indicate comparable overall survival (OS) with TACE and TARE, while reporting a longer time to progression and a higher downstaging effect with TARE treatment. In terms of isolated procedure costs, treatment with TARE is 2 to 3 times more, and in some countries even more, expensive than TACE.

Prognostic value of ADC measurements in predicting overall survival in patients undergoing Y radioembolization for colorectal cancer liver metastases.

Aim: To assess the ability of diffusion-weighted imaging (DWI) in predicting the overall survival in patients who underwent Yttrium 90 radioembolization (Y-RE) for colorectal liver metastases (CLM) with other well-established clinical and imaging parameters by comparing the pre- and post-treatment apparent diffusion coefficient (ADC) values of the lesions.

Methods: A total of 81 metastatic lesions of 27 consecutive patients who underwent DWI before and after the Y-RE session were enrolled in the study. ADC values were calculated from the entire (ADC) and peripheral (ADC) tumor on pre- and post-treatment DWI, and any relative increase in ADC >0% accepted as a functional imaging response.

Worldwide experience with the Endurant Stent graft: review of the literature.

The Endurant Stent-graft System (Medtronic Vascular, Santa Rosa, CA) is a next-generation device intended to expand the applicability of endovascular aortic repair (EVAR). To date, the Endurant has been evaluated in 9 short- and intermediate-term studies, several in patients presenting with challenging aneurysm anatomies. Consistently, the device in these studies has been shown to be safe and effective, with an excellent rate of deployment success and with very low rates of type I/III endoleaks and reinterventions.

Management of endograft infections.

Endovascular abdominal aortic aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR) have become well-accepted alternatives to traditional open surgery because of the diminished perioperative complications. Aortic stent-graft infection is an uncommon complication and little is known about the general features of and potential risk factors for aortic stent-graft infection, and treatment is administered on a case-by-case basis with no consensus guidelines. Despite a low infection rate, the associated mortality rates are extremely high and the morbidity rate, even with aggressive surgical interventions, is also high.
