Improved emergency activation in interventional radiology reduces procedure delay and facilitates treatment success in patients with acute arterial bleedings.

Background: Research of interventional treatment success in arterial bleeding cases is almost exclusively focused on technical and procedural factors. This study investigates the effect of an improved preprocedural activation algorithm for acute arterial bleedings treated by interventional radiology.

Methods: During the three-year study period (2018-2021), the authors implemented an always-reachable, simple-to-remember emergency phone number routed to the responsible interventional radiologist on call and compared this pathway to the previous activation process.

Transjugular intrahepatic portosystemic shunt creation (TIPS) in the angio-CT-a hybrid intervention with image fusion.

Objective: For transjugular intrahepatic portosystemic shunt (TIPS) creation, ultrasound guidance for portal vein puncture is strongly recommended. However, outside regular hours of service, a skilled sonographer might be lacking. Hybrid intervention suites combine CT imaging with conventional angiography allowing to project 3D information into the conventional 2D imaging and further CT-fluoroscopic puncture of the portal vein.

Safety of sheathless vascular access using braided 4 F selective catheters for common body interventions - a retrospective study.

Background: Besides other factors, complication rate of transarterial interventions depends on the size of the vascular access. Therefore, the vascular access is mostly chosen as small as possible while still allowing all planned parts of the intervention. This retrospective analysis is to evaluate the safety and feasibility of sheathless arterial interventions for a broad spectrum of interventions in daily practice.

Efficacy of ultrasound assisted catheter-directed thrombolysis compared to catheter-directed thrombolysis in vitro.

Background: Catheter-directed thrombolysis (CDT) is an effective and safe endovascular method used in critical limb ischemia and many other thromboembolic events. Ultrasound-assisted catheter-directed thrombolysis (US-CDT) is an emerging technique considered to accelerate thrombolysis and therefore is supposed to improve outcome.

Purpose: To evaluate the efficacy of US-CDT in comparison to standard CDT in vitro.

Risk factors assessment for radiographically guided port implantations with forearm access.

Introduction: Port implantations at the forearm are associated with an increased risk of relevant vein thrombosis. Therefore, with this study we sought to identify the responsible risk factors to improve technical quality of the method.

Methods: This is a retrospective analysis of 313 patients with port implantation at the forearm in 2019.
