Peripheral arterial disease and diabetic foot syndrome are common comorbidities in dialysis patients. These conditions are treated with intermittent vacuum therapy in order to increase angiogenesis and perfusion. Some devices encase the lower extremities up to the abdomen. Here we report the case of a patient who had performed peritoneal dialysis for 2 years without complications. Following postoperative intermittent vacuum therapy, he presented with extensive catheter leakage. Ultimately the patient had to be switched to haemodialysis and the catheter had to be removed. This case exempliﬁes that peritoneal dialysis patients have a substantial risk for noninfectious catheter-related complications using vacuum therapy.

It revealed diffuse contrast media accumulation around the catheter. Moreover, a substantial amount of contrast media was detected in the subcutaneous and intermuscular layers on the right side, unrelated to the catheter and the tunnel. This enhancement correlated to former puncture sites of the laparoscopic trocars (Figure 1). Continuous ambulatory peritoneal dialysis (CAPD) had to be stopped and placement of a tunnelled central venous catheter became nec- essary for a transient switch to haemodialysis. After 6 weeks, a renewed attempt to resume CAPD failed, again due to leakage. Another CT scan after 3 months showed no contrast media accumulation in the right rectus abdominis, indicating that leaking ceased with termination of IVT. However, due to contin- uous leakage, the PD catheter had to be explanted. According to the surgical report, catheter material was found to be intact at the time of explantation. Discussion In this report we present a case of PD malfunction following IVT in a patient who was stably performing PD. We hypothesize that IVT not only caused tunnel leakage but also led to diffuse leakage into the abdominal muscles through the former trocar puncture sites. To support the hypothesis, we argue that shear forces in cutaneous and subcutaneous tissue layers caused by alternating pressures led to a reopening of scarred tissue around the old trocar puncture sites. This case report highlights the importance of carefully choosing patients eligible for IVT. The fact that our patient had to be switched to haemodialysis due to the catheter complica- tion caused by IVT emphasizes the need to critically review usual practices with regard to special patient groups, such as CAPD patients. Devices that encompass the abdomen have to be avoided in these patients. In light of the increased utilization of IVT, our case, which demonstrates a severe complication, is intended to alert physicians to potential detrimental effects and Fig. 1.
