Abstract CN46
Background
The PICC in our Day Hospital (DH) has become the central line of choice for the therapeutic management of oncological and hematological patients when the duration does not exceed 6 months. The impact of COVID-19 in these patients led to an increase in risk factors for the occurrence of venous thrombosis (VT) and catheter-related venous thrombosis (CRVT), forcing admission-like immobility, intensification of supportive treatment with granulocyte colony growth factors (G-CSF) and a higher number of PICC insertions in metastatic patients. Given these circumstances, it was decided to use the Blue Advance PICC with antithrombogenic coverage. The objective was record the incidence of symptomatic CRVT related to Blue Advance PICC in oncological and hematological patients in active treatment, as well as the incidence of other complications and causes of withdrawal.
Methods
A retrospective observational study was performed, in a consecutive series of patients from November 2019 to June 2021. All catheters were inserted in DH for oncospecific treatment, using PICC Blue Advance Teleflex Medical®, 4'5Fr, 1 lumen, by ultrasound-guided puncture and tip confirmation by fluoroscopy. Variables recorded: demographic data, diagnosis and stage, treatment administered, date of insertion and removal, vein diameter, cause of removal and complications.
Results
A total of 295 blue PICC were analyzed, with a total length of stay of 46,150 days and a mean of 156 days per catheter. Ninety-eight percent of the PICCs were placed at the first attempt, and the predominant access was the basilic and brachial veins, with diameter between 2.9-5.6mm. There were 9 cases of symptomatic CRVT (3%, 0.19/1000 catheter days), confirmed by Echo-Doppler, which did not require catheter removal and treatment was completed. Six CRVT were diagnosed between the first and third week of insertion in female patients, with cytostatic Adriamycin and G-CSF. The main cause of withdrawal was end of treatment in 94.9%.
Conclusions
The use of the antithrombogenic Blue Advance PICC during the pandemic period, despite the increase in risk factors, kept the incidence rate of symptomatic CRVT unchanged in our historical pre-COVID cohort.
