Factors on patency periods of subcutaneous central venous port: long-term results of 1,408 patients

Patients and methods Between April 2009 and March 2014, subcutaneous venous chest ports were placed in 1,408 patients, 574 women and 834 men, mean age of 55.4±12 1 years. Factors on patency times and complications rates of ports were compared. Age, gender, access, site of malignancy, and coagulation parameters were variables and multivariable Cox regression test was used. The successes of jugular and subclavian groups were compared by univariate Kaplan-Meier survival analysis, also. Port was used for treatment after 3 hours on the procedure day.
