Difficulty removing dialysis cuff catheter after its adhesion to the right atrium.

We describe the case of an elderly Japanese female who had experienced diabetic nephropathy since the year 20xx and had been undergoing dialysis treatment while receiving vascular access interventional therapy (VAIVT) for arteriovenous fistula (AVF) occlusion. The patient visited the clinic/hospital in 20xx+10 with the AVF occlusion; emergency VAIVT was performed but blood flow could not be resumed. The patient was not admitted and was treated as an outpatient, and thus a cuff catheter (Split stream catheter: SST28 cm, Medcomp) was inserted. An infection developed and was successfully treated with antibiotics. The dialysis treatment continued without issue. One year after the cuff catheter's insertion, the patient was admitted due difficulty breathing. Despite continued dialysis treatment with the catheter, the patient died 15 days post-admission. The removal of the catheter proved to be difficult. An autopsy was approved, and the area around the catheter was examined. The adhesion of the catheter to the right atrium was observed, but no infection was detected in the bloodstream. This case illustrates that dialysis with the use of a cuff catheter can be effective.

The Impact of Buttonhole Cannulation on Patients and Staff in Hemodialysis Facilities.

The two reasons that patients desire buttonhole cannulation are avoidance of puncture pain and extension of arteriovenous fistula life. Despite the desire to receive buttonhole cannulation by many patients, medical staff at most local hemodialysis facilities tend to hesitate to implement the cannulation method. This method is used on patients in the dialysis unit at Saitama Medical Center, but tends to be discontinued for those patients upon their transfer to local hemodialysis facilities. Medical staff members of one local hemodialysis facility report the percentage of patients on the buttonhole method was 53% in 2007, but that it sharply decreased to 17% in 2013. Hesitation by local hemodialysis facilities to adopt the buttonhole method is due to, but not limited to, several factors. These factors include the frequently occurring trampoline effect, the difficulty of removing scabs, formation of a false buttonhole track, and the pain from insertion of a dull needle. Perceived differences in the value of buttonhole cannulation may potentially affect communication between patients and staff in local hemodialysis facilities.
