| Popis: | PURPOSE To evaluate the efficacy and safety of use of a retrieval hook for removal of retrievable expandable tracheobronchial stents. MATERIALS AND METHODS With fluoroscopic guidance, a retrieval hook was used to remove 45 retrievable expandable tracheobronchial stents in 31 patients. Indications for stent removal included tissue hyperplasia ( n = 16), stent migration ( n = 10), stent misplacement ( n = 2), tumor overgrowth ( n = 2), persistent gastrobronchial fistula ( n = 1), and incompletely expanded stent ( n = 1). Thirteen stents were electively removed after temporary use. The success rate, causes of failure, and complications related to stent removal with a retrieval hook were analyzed. RESULTS Forty-one of 45 stents (91.1%) were successfully removed with a retrieval hook. The following difficulties were encountered: disruption of the polyurethane membrane ( n = 3) and an untied drawstring ( n = 1). The removal procedure failed in four cases (8.9%) because of excessive tissue hyperplasia ( n = 4) in the proximal portion of the stent. The hook wire fractured in two of the four failed cases. The overall complication rate was 4.4% (minor bleeding, n = 2). CONCLUSION For complications with or temporary use of retrievable expandable tracheobronchial stents, removal with a retrievable hook shows promising initial results. |
