Objectives: To determine risk factors for catheter survival and complications after image-guided implantation of a totally implanted vascular access device (TIVAD).
Methods: A total of 2883 TIVADs (2735 patients, 63.5±13 years old, 1060 men, 1675 women) implanted under guidance by ultrasound and fluoroscopy in our institution from January 2010 to December 2019 were evaluated retrospectively. We used the log rank test and logistic regression to analyse risk factors associated with catheter survival and complications.
Results: Female patients (n=1778; 61.7%; mean catheter survival days: 780.6 days) and those with a haematological malignancy (n=277; 10.1%; mean catheter survival days: 1019 days) had significantly better catheter survival than male patients (n=1105; 38.3%; mean catheter survival days: 645.9 days) and those with a solid organ malignancy (n=2447; 89.5%; mean catheter survival days: 701 days) (p<0.001 and p=0.003). Patients with haematological malignancies and benign vascular inflammatory disease (n=11; 0.4%) were vulnerable to infection (n=96; 3.3%) (p<0.001 and p=0.004). Thrombotic malfunction (n=38; 1.3%) was significantly more common in females than males (p=0.005). Non-thrombotic malfunction (n=16; 0.6%) showed a significant association with left positioning of the TIVAD (n=410; 14.2%) (p=0.043). Wound dehiscence (n=3; 0.1%) was significantly more frequent in punctured veins other (n=23; 0.8%) than the internal jugular vein (p<0.001).
Conclusions: Increased attention should be paid to patients with an underlying haematological malignancy, underlying vascular inflammatory disease, female patients, older patients, those accessed via a vein other than the IJV, those with left positioning of the TIVAD system or those with a prolonged TIVAD maintenance.Reference:

Implantable port survival reviewed by gender and disease. With results demonstrating how various risk factors impact on how long an IV port lasts. This is what makes the specialism of vascular access interesting.
I hope the future identifies all the variables associated with vascular access problems and some form of AI helps deliver the solution on a patient by patient basis.
