Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

Advanced Materials Technologies, Volume 11, Issue 7, 6 April 2026.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Difficulty removing a totally implantable venous access port: A case report

World Journal of Clinical Cases
BACKGROUND This case report examines the challenges associated with removing a totally implantable venous access port (TIVAP) used for long-term chemotherapy in a patient with breast cancer. Prolonged use of TIVAPs can result in complications such as catheter kinking, thrombosis, and adhesions between the catheter and surrounding tissues ...

A Retrospective Clinical Study: Complications of Totally Implanted Central Venous Access Ports

The Korean Journal of Thoracic and Cardiovascular Surgery, 2014
When managing patients who require repeated venous access, gaining a viable intravenous route has been problematic. To improve the situation, various studies on techniques for venous access have been conducted. The aim of this study is to evaluate the clinical results of complications following totally implanted central venous access port (TICVAP ...

Use of a hydrophilic coating wire reduces significantly the rate of central vein punctures and the incidence of pneumothorax in totally implantable access port (TIAP) surgery

BMC Surgery, 2017
Background Insertion of a Totally Implantable Access Port (TIAP) can be performed either via Central Vein Puncture (CVP) or Brachiocephalic Vein Cut-down (venous section-VS). The primary success rate of TIAP implantation using VS rarely ever achieves 100%
