Abstract
OBJECTIVE To describe and evaluate outcomes of a multidisciplinary, minimally invasive approach combining lacrimoscopy and fluoroscopically guided stenting for management of nasolacrimal apparatus (NLA) obstruction in dogs. DESIGN Prospective, nonrandomized clinical trial. ANIMALS 16 client-owned dogs with confirmed NLA obstruction. PROCEDURES Dogs underwent CT contrast dacryocystorhinography, rhinoscopy, and lacrimoscopy. Whenever possible, the NLA was stented, typically with fluo-roscopic guidance. RESULTS Median duration of clinical signs prior to treatment was 3.2 months (range, 0.2 to 14 months). Causes of NLA obstruction were a foreign body (n = 5), dacryocystitis (4), stenosis secondary to fibrosis (3), granulation tissue (1), or granulation tissue in association with a small foreign body (1); a cause was not identified in 2 dogs. Stents were placed in 14 of 16 (88%) dogs for a median duration of 5.6 weeks (range, 1.3 to 9.4 weeks). Stenting was not possible in 2 dogs with stenosis of the NLA secondary to granulation tissue or fibrosis. Owners of all 16 dogs reported at least 60% clinical improvement with median improvement rated as 95%, and owners of 8 dogs reporting complete resolution of signs. Two dogs required antimicrobial administration because of dacryocystitis that persisted after stent removal; a foreign body was not found in either dog. CONCLUSIONS AND CLINICAL RELEVANCE Overall clinical response and owner-rated improvement for dogs with NLA obstruction that underwent lacrimoscopy and fluoroscopically guided stenting were high, especially given that these dogs had failed to respond to conventional treatment.
