Role of Fogarty catheter manipulation in management of migrated, nonfunctional peritoneal dialysis catheters.

Peritoneal dialysis (PD) catheter migration to the upper abdomen is not an uncommon cause of catheter failure. We prospectively examined the role of the Fogarty catheter manipulation technique to reposition the PD catheter in the pelvis and regain patency. All patients with PD catheter malfunction caused by migration, confirmed by abdominal radiograph, underwent the same protocol. The patient was placed flat on the back, and the Fogarty was advanced into the PD catheter to a premarked point at which the end of the Fogarty was near the end of the PD catheter. The Fogarty balloon was inflated with 0.5 mL of sterile saline, and manipulation was performed by tugging movements until proper placement of the PD catheter into the pelvis was suspected. Infusion and drainage of dialysate was performed to determine patency. The return of the PD catheter into the pelvis was then confirmed by repeated radiograph. Success rates of Fogarty catheter manipulation, early and late recurrence (remigration < or =90 days or >90 days), and complications were prospectively examined in 232 patients over a 6-year period. Catheter migration occurred in 34 of 232 patients (15% incidence). All patients had curled-end, double-cuffed, non-swan-neck PD catheters. Successful repositioning occurred in 24 of 34 patients (71%). None of the 24 repositioned catheters had early recurrence, and 1 of 24 catheters (4%) had late recurrence. None of the patients had procedure-related peritonitis, bowel perforation, or exit-site trauma. These results show that PD catheter migration is relatively common (15%). The Fogarty manipulation technique is a simple, cost-effective way to prolong PD catheter life and preserve its long-term patency. This eliminates the need for surgical intervention in approximately 70% of patients with PD catheter migration.
