According to the literature, a retrospective observational study evaluated all patients with pd (peritonial dialysis) catheter malfunction that were referred for fluoroscopic intervention with reported catheter inflow and/or outflow obstruction within a 10-month period (between october 2018 and august 2019).This study evaluated two main classes of mechanical catheter failure: malposition and catheter obstruction.All forty patients had the same make and model of pd catheter with documented catheter malfunction: inflow obstruction in 5% (2/41), outflow obstruction in 63% (26/41), both inflow and outflow obstruction in 29% (12/41), and pain without inflow or outflow obstruction in 2% (1/41).The mean time between pd catheter insertion and presentation to the interventional radiology suite was 317 days (range 21-1719 days).Malpositioned catheters were identified during fluoroscopy or by previous imaging such as an abdominal radiograph or ct (computerized tomography).If failure occurred, the pd catheters were salvaged surgically via mini-laparotomy and/or the patient was switched to hemodialysis.Two patients developed complications.One was an exit site infection and the other was culture-negative peritonitis.Both instances were treated with antibiotics per protocol without hospitalization or further complications.Article : salvage of malfunctioning peritoneal dialysis catheters : an algorithm for recanalization and repositioning | authors : li p, choo d, deved v, shah n, shurraw s, zuidema s, samji r, year 2021,journal of vascular & interventional radiology.
