To the Editor:

We are writing in reference to the article published in February 2020 by Pérez Calvo et al.,1 “Comparative Study of Access Routes for Port-A-Cath® Implantation”, which we have read with great interest.

The number of patients treated with implantable venous devices has increased considerably due to the increase in cancer patients, and we must make an effort to study the factors associated with their application and complications. However, to complement this study, we would like to expand on the information regarding the risk factors related to complications secondary to the use of these devices.

Pérez Calvo et al.1 report a lower rate of overall complications using vein dissection (VD) versus vein puncture (VP). Many of these complications are directly related to the surgical technique used: pneumothorax, hematoma, vascular or nerve injury, etc. Thus, we consider the comparison between VP and VD adequate in terms of these complications.

However, the most frequent complications in the article were infection and thrombosis. Multiple factors have been directly related to both complications. Neutropenia, medication administered, infusion of parenteral nutrition and patient comorbidities are the risk factors most frequently related to infection or thrombosis after the placement of a central venous catheter.2–5 Pérez Calvo et al.1 analyzed age, sex, BMI, ASA, laterality and reason for placing the device as comparative variables between both groups, ignoring the previously mentioned factors. These could act as confounders, distorting the overall results of the study.

Penel et al.2 conducted a multivariate analysis, which identified young age, surgical difficulties and the administration of parenteral nutrition as risk factors that were significantly associated with systemic infection. When comparing VD and VP, Aspiazu et al.,3 found that the use of small-caliber catheters (<6 French) was a risk factor for a higher infection rate. Other factors related to infection were hematologic neoplasms, therapy administered through the catheter, and neutropenia, as well as its duration.2,4,5 The use of antibiotics has been considered a protective factor during the insertion of these devices,6 but the results of several studies analyzing this association have been controversial.

Thus, due to the growing use of these devices in recent years, we want to congratulate the authors for their contribution towards defining the advantages and disadvantages of placement with both techniques described. However, we consider the comparison of the two workgroups interesting given the previously mentioned factors. We feel that these results are a significant contribution to the scientific literature in order to promote the safe use of these devices, which are increasingly necessary for our patients.
