Abstract

Purpose Groshong valved catheters require retrograde tunneling and a port chamber needs to be attached to the catheter after trimming. During this process, working space constraints are generally faced by operators. We describe a novel technique to improve the comfort of the operator while working in a constrained space.

Materials and Methods The port catheter with the distal valve is retrogradely tunneled and trimmed. Thread from absorbable surgical suture is used to anchor the catheter lock. Anchored catheter lock is comfortably pushed over the catheter into the subcutaneous tunnel without it being migrated proximally. Once the port chamber is attached to the catheter, the catheter lock is retrieved back and moved to the locking position. We retrospectively analyzed implantable ports for smoothness of curves and outcomes in terms of catheter days.

Results Technical success was achieved in all patients. There were no periprocedural complications. Clinical success was achieved in 27/29 cases. Early port removal was done due to infection in one patient and for nonhealing of the wound in one patient.

Conclusion The catheter lock anchor is a safe and useful technique for the placement of valved ports. A satisfactory catheter-nut angle can be achieved with this technique.
