Vascular access in gynecologic cancer using the Groshong right atrial catheter

Area of Science:

• Oncology
• Vascular Access Devices
• Gynecologic Oncology

Background:

• Invasive gynecologic cancer often requires long-term venous access for treatment.
• Traditional central venous catheters pose risks such as air embolism and back-bleeding.

Purpose of the Study:

• To evaluate the safety and efficacy of the Groshong catheter in patients with invasive gynecologic cancer.
• To assess the complication rates and practical benefits of Groshong catheter insertion and use.

Main Methods:

• Forty-one Groshong catheters were inserted in 38 patients with invasive gynecologic cancer.
• Various venous access approaches (supraclavicular, infraclavicular, external jugular) were utilized.
• Catheters were primarily inserted at the bedside using the Seldinger technique without fluoroscopy.

Main Results:

• A cumulative total of 4170 days of patient use was achieved with a mean indwelling time of 93 days.
• Major complications included two pneumothoraces and three cases of catheter-related sepsis.
• The Groshong catheter's unique valve design minimized air embolism and back-bleeding, eliminating the need for heparin flushes.

Conclusions:

• Groshong catheter insertion and maintenance are simple, time-saving, and cost-effective bedside procedures.
• The catheter's design offers significant advantages for patients requiring long-term venous access, including chemotherapy and hyperalimentation.
• Early placement of Groshong catheters is recommended for oncology patients to facilitate treatment protocols and outpatient therapy.
