Bone mineral density as a prognostic marker in patients with biliary tract cancer undergoing surgery.

Background: Biliary tract cancer (BTC) is one of the most aggressive malignancies and surgery represents the only curative treatment approach. However, even in patients with complete tumor resection 5-year survival rates are below 30%. So far, prognostic markers to assess the outcome of these patients are lacking.

Evaluating the length, diameter, and stenosis of deep circumflex iliac artery and neighboring arteries based on digital subtraction angiography.

Background: The vascularized iliac bone crest flap offers excellent usable bone in terms of volume and quality. Its nourishing vessel, the deep circumflex iliac artery (DCIA), although relatively short, is reliable vessel. Digital subtraction angiography presents still the gold standard for diagnostic purpose.

Sarcopenia indicate poor survival in patients undergoing transarterial chemoembolization (TACE) for hepatic malignancies.

Background: Patient selection for transarterial chemoembolization (TACE) has remained challenging. Currently used markers mainly reflect liver function and turned out as less reliable in larger clinical trials. The patients´ body composition has been linked with patient outcome in different cancers.

Complication Management and Prevention in Vascular and non-vascular Interventions.

Purpose: This overview summarizes key points of complication management in vascular and non-vascular interventions, particularly focusing on complication prevention and practiced safety culture. Flowcharts for intervention planning and implementation are outlined, and recording systems and conferences are explained in the context of failure analysis. In addition, troubleshooting by interventionalists on patient cases is presented.
