Abstract Background Chemoport (totally implantable venous access device) and its catheter system are used to administer long-term chemotherapy in cancer patients. The objective of this study was to analyze the complications associated with chemoport insertion in various cancer patients. Material and Methods A total number of 168 chemoports along with polyurethane catheters were inserted in various cancer patients over a period of 3 years. 9.6 F polyurethane catheters were put by a team of surgical oncologists in operation theater under general or local anesthesia. Analysis of the complications was done until the chemoport was removed due to any reason. Results Out of 168 patients, 30 (17.85%) developed complications. Complications included arterial puncture, malposition of the catheter tip, pneumothorax, hematoma, seroma, deep vein thrombosis, fracture of the catheter, a reversal of port, infections, and thrombosis of the catheter. Only a few required premature port and catheter removal. Conclusion There was a low rate of complications associated with chemoport using a polyurethane type of catheter system. However, infection-related complications were comparatively more common in our series. Chemoport requires expert handling, patient education, strict follow-up, and dedicated teamwork to minimize complications.

Background The goals of infusion therapy are to preserve vascular health and safely deliver needed treatment. Achieving these goals is challenging in critical care because of the complexity of the treatment required. Daily justification of retaining an existing central venous catheter also creates urgency to change to a peripheral vascular access device. The midline catheter has had a resurgence in use because of the need for a long-term peripheral vascular access device not linked to central catheter–associated bloodstream infection risk. Objective To review the characteristics of midline catheters, the benefits and risks of midline catheters, and current evidence regarding midline catheter use in critical care. Results Research related to midline catheters has greatly expanded the body of knowledge regarding vascular access device selection and midline catheter use. Discussion Although the quality and results of research on vascular access devices vary widely, a more accurate safety profile is emerging to illustrate how midline catheter use can support the goals of infusion therapy. Conclusions Optimizing vascular access device selection requires recognition that every vascular access device can cause patient harm. Although the midline catheter appears to fill an important niche in infusion therapy, use of the midline catheter should be carefully evaluated. Midline catheters should not be used as a catheter-associated bloodstream infection prevention strategy, should be inserted to administer peripherally compatible solutions, and should be considered for short-term continuous vesicant therapy only in emergent situations until more definitive vascular access can be achieved.

Abstract Venous access device-related bloodstream infections (VAD-BSIs) with coagulase-negative staphylococci (CoNS) are common complications after allogeneic hematopoietic cell transplantation (alloHCT). So far, the standard systemic antimicrobial therapy for uncomplicated VAD-BSIs with methicillin-resistant CoNS consisted of intravenous (IV) vancomycin (vanco). This approach requires hospitalization, necessitates new competent venous access, exposes patients to potential (mainly renal) toxicity and increases the risk of commensal flora dysbiosis with selection of vanco-resistant enterococci. Patients after alloHCT are particularly at risk of iatrogenic and nosocomial complications. In addition, repeated hospitalizations can impact autonomy and quality of life and are associated with significant costs. Minocycline (mino) is an oral antimicrobial agent that has strong in vitro effects on most Gram positive bacteria and potential anti-biofilm activity, and can be used in the clinic for some CoNS infections. Our infectious disease specialists proposed that systemic therapy with oral mino could be used for the management of uncomplicated VAD-BSIs, primarily when the reference treatment with IV vanco was not possible (renal failure or allergy) or when hospitalization was refused by patients. We retrospectively analyzed the results of this mino-based approach. From January 2012 to December 2020, we treated 24 uncomplicated VAD-BSIs with CoNS in 23 alloHCT patients aged 17-72y with oral mino. Uncomplicated VAD-BSIs were defined as 2 or more blood cultures positive for the same CoNS drawn consecutively peripherally and through the VAD, in patients without signs of sepsis, cellulitis or suppurative thrombophlebitis and without endovascular implant or orthopedic material. VAD were implantable ports (n=17), tunneled catheter (n=1) or PICC-lines (n=6). Pathogens were S. epidermidis (n= 21) or S. haemolyticus (n=3). CoNS were in vitro susceptible to mino according to EUCAST guidelines (with MIC <= 0.5mg/L, predominantly). Mino was administered at a dose of 100 mg BID for 7-14 days. For 8 VAD-BSIs, patients were initially treated with IV vanco for the first 1-3 days followed by oral mino, while 16 VAD-SIBs were managed with oral mino alone. VAD management consisted of catheter removal (for tunneled and PICC-lines, n=7) or antibiotic locks with vanco (n=15) or gentamicin (n=2) administered at least every other day for 14 days (for ports). Overall, clearance of bacteremia (as assessed by negativity of surveillance peripheral blood cultures with the same CoNS drawn between d+3 and +30 after initiation of systemic therapy) was achieved in all but 1 patient (with port, treated with mino alone) who had persistent bacteremia at day +9. No complication such as suppurative thrombophlebitis, endocarditis or metastatic foci of infection was observed in any patient during the 3-month period after initiation of treatment. Among the 17 patients for whom VAD salvage was attempted, VAD decontamination was successful in 10 cases while 4 patients experienced persistently positive VAD-derived blood cultures during the early (d+3 to +14) surveillance period and 3 patients experienced delayed relapse of VAD-BSIs with the same CoNS 1-3 months later (with 1 patient with cellulitis). All these events led to VAD removal. Treatment with mino was well tolerated with the exception of mild skin rash in one patient. Our results in this retrospective cohort suggest that oral mino can be a promising alternative to standard IV vanco for systemic therapy in VAD-BSIs with CoNS and that a strategy combining oral mino and antibiotic locks may salvage VAD in approximately half of the cases. This remains to be confirmed in prospective studies. Disclosures No relevant conflicts of interest to declare.

Abstract Background Selection of a vascular access device (VAD) is an important consideration for patients receiving outpatient parenteral antimicrobial therapy (OPAT). Midline catheters (MC) and peripherally inserted central catheters (PICC) are the most commonly placed VADs, with the former recommended by national guidelines to be used for durations no longer than two weeks. These recommendations, however, are based on limited data from heterogeneous populations. As such, we aim to further characterize VAD-associated complications specifically in patients receiving antimicrobials. Methods We conducted a retrospective cohort study that included adult patients discharged on OPAT with a newly inserted MC or PICC between January 2020 and August 2020. Patients with non-OPAT VAD indications were excluded. The primary outcome was the incidence of VAD-associated complications, which was further assessed by type and severity. The secondary outcome was time to complication. Multivariable Poisson regression was used to assess the association between VAD type and incidence of VAD-associated complications. Results A total of 190 encounters from 181 patients were included for analysis. Baseline demographics are detailed in Table 1. Despite a higher number of complications in the PICC group, rates per 1000 VAD days were not significantly different between VAD types (Table 2). Median time to first complication was 17 days in the overall cohort. Multivariable regression analysis showed those with a dermatologic history had a four-fold increased risk for VAD-associated complications (Table 3). VAD type was not independently associated with the risk of developing a complication. Conclusion Our results suggest that the development of VAD-associated complications was strongly associated with patients’ dermatologic history. To our knowledge, dermatologic history has not been previously identified as a risk factor for VAD-associated complications. Thorough assessment of patient-specific risk factors can inform optimal VAD selection for patients discharged on OPAT. Further studies are needed to assess the safety of MC for extended OPAT use.

Implanted ports have provided clinicians with long term venous accessibility, while maintaining comfort and convenience for their patients. One of the most commonly used implanted ports for oncological access is a Mediport (Norfork Medical, Skokie, IL). Guidelines (INS2021) strongly recommend placing central catheter tips at the cavo-atrial junction. In fact, too deep atrium position may be associated with micro-traumatism, possibly leading to a catheter associated right atrial thrombosis (CRAT). No significant literature discusses the possibility of such port masses being seeded by a bacteria, as in the case for endocarditis, which was seen in our patient. In the following case report, we will explore the case of a 41-year-old female with metastatic urothelial carcinoma who developed multiple right atrial masses possibly associated with a deeply seated totally implanted vascular access device (TIVAD) tip within the right atrial wall. These right atrial masses were of unknown origin, and in the setting of MRSA bacteremia, multiple possible etiologies would be discussed. We will also explore ways in which similar complications can be easily prevented in the future.
