Differences in Radiation Exposure of CT-Guided Percutaneous Manual and Powered Drill Bone Biopsy.
Apart from the commonly applied manual needle biopsy, CT-guided percutaneous biopsies of bone lesions can be performed with battery-powered drill biopsy systems. Due to assumably different radiation doses and procedural durations, the aim of this study is to examine radiation exposure and establish local diagnostic reference levels (DRLs) of CT-guided bone biopsies of different anatomical regions. ⋯ Level 3.

Technique-Based Evaluation of Clinical Outcomes and Aortic Remodelling Following TEVAR in Acute and Subacute Type B Aortic Dissection.
To evaluate the clinical outcomes and aortic remodelling rates following thoracic endovascular aortic repair (TEVAR) for acute or subacute type B aortic dissection (TBAD) based on technique. ⋯ Endovascular intervention for acute and subacute TBAD is safe with a high rate of technical success. STABILISE results in higher aortic remodelling at the infra-renal aorta (82%) compared to TEVAR alone (20%) but risks aortic rupture from balloon moulding.

Successful Revascularization has a Significant Impact on Limb Salvage Rate and Wound Healing for Patients with Diabetic Foot Ulcers: Single-Centre Retrospective Analysis with a Multidisciplinary Approach.
Analyze the impact of endovascular revascularization on major amputation rates and wound healing for patients with diabetic foot ulcers (DFUs). ⋯ Endovascular revascularization for patients with DFUs is safe and has a significant impact on limb salvage and wound healing.

Safety and Efficacy of Aortic Vs Internal Iliac Balloon Occlusion for Cesarean Delivery in Coexisting Placenta Accreta and Placenta Previa.
To investigate safety and efficacy of intra-aortic balloon occlusion (IABO) versus internal iliac artery balloon occlusion (IIABO) for cesarean delivery in coexisting placenta accreta and placenta previa. ⋯ IABO and IIABO are safe and effective options for cesarean delivery in patients with combined placenta accreta and placenta previa. The average operation time, balloon occlusion time, and fetal radiation dose in patients with IABO are less than in patients with IIABO. There were no complications related to balloon occlusion of the aorta or internal iliac artery.

Case ReportsManagement of Phlegmasia Cerulea Dolens with Percutaneous Mechanical Thrombectomy.
Advanced cases of phlegmasia cerulea dolens (PCD) with absent pedal pulses, sensory/motor deficits, and/or venous gangrene likely require more rapid restoration of flow compared to cases without these factors to prevent progression and associated morbidity/mortality. We present a case of PCD with absent pedal pulses and sensory deficit managed successfully with emergent percutaneous mechanical thrombectomy using Inari ClotTriever (Inari Medical, Irvine, CA) with immediate clinical resolution, including restoration of pedal pulses ~ 45 min after thrombectomy. Percutaneous mechanical thrombectomy with the ClotTriever device has the ability to immediately restore venous flow reversing the pathophysiology of PCD in a short time period similar to surgical embolectomy and may be an alternative treatment strategy in patients with phlegmasia cerulea dolens of high severity.
