Implantable port

Brent Burbridge, Kunal Goyal
INTRODUCTION: Venous access devices are essential for the provision of care for patients requiring chemotherapy. Totally implanted venous access devices (TIVADs), also known as ports, are an option for infusion care. Medical devices have an impact upon patient quality of life. We assessed the impact on quality of life and satisfaction with their venous device, for patients with a chest TIVAD versus an upper arm TIVAD. MATERIALS AND METHODS: Sequential subjects were administered a questionnaire, "Quality of Life Assessment, Venous Device - Port (QLAVD-P)" at the time of their TIVAD removal...

A 60-year-old woman was referred to our hospital with an anterior mediastinal tumor measuring 3.5 cm in diameter on computed tomography (CT). We performed tumor resection by video-assisted thoracic surgery (VATS) with three ports. The final diagnosis was Type A Masaoka Stage I thymoma. On follow-up CT performed 36 months after the operation, two pleural tumors were detected at the port sites through which the forceps and ultrasonic scalpel had passed repeatedly during the operation. We therefore performed a second operation and enucleated the tumors while preserving the ribs...

Children with malignancy require venous access that is reliable, safe and compliant on a long-term basis. There is little data available on utilization of totally implantable venous access devices (TIVAD) for long term chemotherapy in children in an Indian setting [1]. We report our long-term follow-up results of utilization of totally implantable venous access devices for long-term chemotherapy in children. This was a retrospective analysis of 122 children requiring long-term chemotherapy done between January 2008 and December 2013...

INTRODUCTION: To follow international guidelines and protect healthcare workers from needle stick injuries, manufacturers now provide safety non-coring needles. METHODS: Numerical simulations show the potential efficacy of infusion and flushing flow in straight and curved side wall port chambers from a beveled non-coring needle (BNCN) or a bevel-free cannula (BFC). RESULTS: In straight and curved side wall port chambers, the stream of flow with a BNCN is determined by the direction of the bevel, whereas the outlet stream from a BFC leads to a cylindrical symmetric flow...

PURPOSE: The current emphasis on fiscally responsible health spending in the era of the Affordable Care Act and other health care reform necessitates cost-conscious delivery of care. "Value" in health care is defined as the quality of care divided by the cost. As such, health systems optimize value by providing the most cost-effective care possible without sacrificing safety or outcomes. Elective, minimal risk surgical procedures in children may be value-enhanced by moving from an operating room (OR) to a more cost-efficient setting...

There is renewed interest in sparing the pectoralis major muscle in implant breast reconstruction, placing the implant in the subcutaneous position. This advance is made reliable by improvements in mastectomy skin flap quality, evolution of technique, and increased awareness of breast animation deformity. This retrospective review presents 13 patients (23 breasts) reconstructed immediately with placing the definitive implant in the subcutaneous space without disruption of the underlying chest muscles. None of the 13 patients had breast animation deformity postoperatively...

Biomedical translational research frequently incorporates collection of CSF from NHP, because CSF drug levels are used as a surrogate for CNS tissue penetration in pharmacokinetic and dynamic studies. Surgical placement of a CNS ventricular catheter reservoir for CSF collection is an intensive model to create and maintain and thus may not be feasible or practical for short-term studies. Furthermore, previous NHP lumbar port models require laminectomy for catheter placement. The new model uses a minimally invasive technique for percutaneous placement of a lumbar catheter to create a closed, subcutaneous system for effective, repeated CSF sample collection...

BACKGROUND: The totally implantable port is a common central venous access device. The cost of implantation and maintenance however is very expensive. At present, the biggest problem regarding the promotion and the use of implantable ports in China is lack of well trained professional healthcare providers. Furthermore, maintenance of totally implantable ports by nurses is poor and patients may easily get complications. AIMS/OBJECTIVES: This project aimed to reduce the incidence of complications among general surgery patients with implantable ports, and improve healthcare safety and the care process, strictly in compliance with current evidence-based criteria...

PURPOSE: Totally implantable vascular access devices (TIVADs) are widely used to administer chemotherapy to cancer patients. While great progress has been made with respect to breast surgical reconstruction to take into account both aesthetics and patients' perceptions of body integrity, these aspects have not been considered with regard to the impact of TIVAD. In order to address this practice gap, we have adapted our TIVAD implantation technique to improve cosmetic results. The aim of this study was to assess breast cancer patients' comfort level and aesthetic satisfaction with regard to TIVAD insertion...
