“…Postoperative and respiratory systems in humans has recently described for the management of tracheal collapse, nasopharygeal stenosis, oesophageal stricture, colorectal stricture, ureteral stenosis and urethral stenosis in veterinary medicine (Cook et al 2013;Lam et al 2013;Hill et al 2014;Tinga et al 2015). The implantation of self-expandable metallic stents appears to be especially promising for intraluminal stabilisation of collapsed trachea in that it can facilitate an immediate improvement of clinical signs, requires only short anaesthetic time, is minimally invasive and allows access to the entire trachea (Beal 2013).…”

“…The implantation of self-expandable metallic stents appears to be especially promising for intraluminal stabilisation of collapsed trachea in that it can facilitate an immediate improvement of clinical signs, requires only short anaesthetic time, is minimally invasive and allows access to the entire trachea (Beal 2013). Uncovered nitinol wire mesh stents with single-wire woven structures are increasingly being used for the management of dogs with end stage tracheal collapse (Gellasch et al 2002;Durant et al 2012;Tinga et al 2015). However, despite the major advantages of endotracheal stenting, severe complications including stent fracture have been described (Mittleman et al 2004;Woo et al 2007).…”

“…These complications can occur when stent diameter is either oversized or undersized leading to stent length that is unexpectedly long or short (Mittleman et al 2004;Beal 2013). Currently available methods for determining optimal stent size include computed tomography, bronchoscopy, radiography and fluoroscopic catheter markers (Gellasch et al 2002;Maetani et al 2007;Beal 2013;Tinga et al 2015). Computed tomography and bronchoscopy can provide precise diameter and length measurements of the trachea (Gellasch et al 2002;Maetani et al 2007).…”

“…In addition, the ability to recover from anaesthesia should be taken into account since dogs with tracheal collapse often require emergency management with a focus on the use of a self-expanding stent placement as an emergency procedure (Beal 2013). Inspiratory and expiratory thoracic radiographs can be considered as a safe procedure to determine diameter and length of the tracheal lesion in dogs with endstage tracheal collapse that fail to respond to routine emergency management strategies (Sura and Krahwinkel 2008;Tinga et al 2015). As described earlier, a stent diameter that is 10% to 20% larger than the maximum measured tracheal diameter can be chosen (Sura and Krahwinkel 2008).…”

“…Treatments usually include medical therapy that can be considered as the first option in patients with mild clinical signs, and surgical therapy that can be employed for patients with unsatisfactory response to medical therapy (Kim et al 2008;Sura and Krahwinkel 2008;Beal 2013). The primary goal of surgical therapy for tracheal collapse is to restore normal tracheal lumen by supporting the dorsal tracheal membrane and cartilage rings without disruption of blood and nerve supply to the trachea (Nelson 2003;Fossum 2007;Tinga et al 2015). Various surgical techniques have been described, including plication of the dorsal tracheal membrane, tracheal ring chondrotomy, extraluminal prostheses and intraluminal stents (Buback et al 1996;Ayres and Holmberg 1999;Moritz et al 2004).…”

A 2.7 kg, 11-year-old, castrated male Maltese dog was presented for evaluation of a 2-year history of intractable coughing, dyspnoea and cyanosis. A diagnosis of tracheal collapse with myxomatous mitral valve disease was made on the basis of inspiratory and expiratory thoracic radiographs, fluoroscopy and echocardiography. Measurement for stent size selection was performed on thoracic radiographs. A 10 mm (diameter) × 70 mm (length) self-expanding double-wire woven uncovered nitinol stent was used for intratracheal implantation and was deployed under fluoroscopic guidance. On thoracic radiography seven days after surgery, the position of the stent remained unchanged. On presentation six months after surgery, the owner reported that the dog was doing well without medical management. Although studies of various intraluminal stents have been reported in dogs, to the authors' knowledge, use of a double-wire woven uncovered nitinol stent has not been reported previously for the management of a dog with tracheal collapse. Since this particular type of stent with unfixed individual cells provided proper airway patency without stent fracture in the dog in this report, this stent might be used as an alternative to other commercially available nitinol stents in cases of thoracic inlet collapse.
