Dermal securement of port catheters in obese patients

Abstract

BackgroundPort catheters are often used for patients who require long-term central venous access. However, thick subcutaneous fat may obscure the port location and limit the degree to which the port is palpable. We describe a method to improve port catheter placement in overweight and obese patients. MethodsPort catheters were placed in three overweight and obese patients after a diagnosis of malignancy. Rather than securing the port onto muscular fascia as is typically done, securing sutures were directed toward the dermis, elevating the port toward the skin and creating skin dimpling for visual reference. ResultsThere were no intra- or postoperative complications. The ports remain visible and palpable >9 months after placement and there have been no reported difficulties with access. ConclusionThis method improves visualization of the port location and facilitates palpation of the port during Huber needle access.
