Randomized trial of conventional transseptal needle versus radiofrequency energy needle puncture for left atrial access (the TRAVERSE-LA study). [PDF]

, 2013
BackgroundTransseptal puncture is a critical step in achieving left atrial (LA) access for a variety of cardiac procedures. Although the mechanical Brockenbrough needle has historically been used for this procedure, a needle employing radiofrequency (RF)

Preoperative Radar Localisation of Impalpable Breast and Axillary Lesions: Initial Experience in an Australian Tertiary Centre

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Image‐guided radar localisation (RL) is a wire‐free alternative to hookwire localisation (HWL) for preoperative localisation of impalpable breast and axillary lesions, with potential logistical and technical advantages. This study assesses clinical utility, accuracy of placement and surgical oncologic outcome metrics for RL using ...

Safer Access With Fewer Transfusions: Revisiting Platelet Thresholds in Pediatric Central Venous Catheterization

European Journal of Haematology, EarlyView.
ABSTRACT Background Central venous catheters (CVCs) are essential in pediatric hematology‐oncology, for the administration of chemotherapy and supportive therapy. Thrombocytopenia increases the risk of bleeding and current guidelines recommend prophylactic platelet transfusions below 40–50 × 109/L, though evidence is limited and transfusions entail ...

Long‐term results of palliative placement of very low‐axial force self‐expandable metallic stents for malignant colorectal obstruction

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives Stent placement is a standard option for palliative decompression in patients with malignant colorectal obstruction. Long‐term stent placement is associated with perforation, migration, and stent occlusion. Perforation is associated with life expectancy.

Feasibility Study of Microneedle Fabrication from a thin Nitinol Wire Using a CW Single-Mode Fiber Laser

Open Engineering, 2019
In this paper, feasibility studies are presented on microneedle fabrication by using a multiple-pulse laser microhole drilling technique to drill an axial hole into a thin nitinol wire of 150 μm in diameter. Nitinol is chosen for its biocompatibility and

Efficacy and Safety of Multihole Partially Covered Self‐Expandable Metal Stents for Distal Malignant Biliary Obstruction: A Single‐Center Retrospective Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Covered self‐expandable metal stents (SEMS) are the standard for managing unresectable distal malignant biliary obstruction (DMBO), as they prolong the time to recurrent biliary obstruction (TRBO). However, fully covered SEMS (FCSEMS) increases the risk of cholecystitis and pancreatitis.

Role of Endoscopic Ultrasound‐guided Gastroenterostomy for Benign Gastric Outlet Obstruction

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Benign gastric outlet obstruction (GOO) often results from intrinsic conditions like peptic strictures, caustic‐induced stricture, and surgical anastomoses, and extrinsic conditions like pancreatitis, hematoma, and superior mesenteric artery syndrome.
