Airway management for tracheal resection proximal to carina in a cat

Abstract

tracheal tumours in cats are rare, and most primary tumours respond well to complete surgical excision. providing secure airway management during resection of the trachea is particularly challenging and in some cases represents a limitation to surgery. We present the case of a cat with a primary tracheal neoplasm located close to the carina, undergoing complete resection. successful management of the airway was accomplished by intubating the distal tracheal stump with a modified polyvinyl chloride endotracheal tube. effective seal of the airway and adequate ventilation of both lungs were achieved. We describe a reliable, simple, low-cost technique which provides control of the airways even in situations where the distal stump of the trachea is either too short or non-existent.

Tracheal Squamous Cell Carcinoma Treated with Tracheal Resection and Anastomosis in a Cat

“…The remaining 51 cases have been diagnosed as neoplastic. The most common feline intraluminal tracheal neoplasms include lymphoma (18) [1,2,4,[14][15][16][17][18][19][20][21][22], adenocarcinoma (15) [1,3,4,8,21,[23][24][25][26][27][28], and squamous cell carcinoma (6) [1,[4][5][6][7][8]. The rest include various carcinomas including basal cell carcinomas (2) [4,29], seromucinous carcinoma (1) [9], neuroendocrine carcinoma (1) [10], and unclassified carcinomas (4) [4,8,9,30], as well as one each of leiomyosarcoma [31], histiocytic sarcoma (disseminated) [11], and a plasmacytoma [8].…”

Severe hypercapnia associated with a chemodectoma causing profound tracheal narrowing in a cat

“…Other potential causes include (1) stenosis after traumatic intubation,14 (2) stenosis after tracheotomy14 15 and (3) tracheal neoplasia 14 16 17. Successful management of tracheal resection due to neoplasia18 and tracheal rupture19 20 in cats has been reported. These cases were managed with different techniques, including a three‐phase approach to ventilation adapted to three different stages of surgical intervention, enabling maintenance of anaesthesia with inhalation agents,18 one lung ventilation with total intravenous anaesthesia19 and jet ventilation via a feeding tube 20.…”

One study in humans describes different airway management techniques for placement of a tracheal stent, namely, cuffed ETT, laryngeal mask airway, jet ventilation and venoarterial extracorporeal membrane oxygenation 21.…”

Diagnosis and treatment of a low‐grade tracheal B‐cell lymphoma and associated complications in a mixed breed cat

“…More details on the complex intraoperative airway management can be found in a case report by Calice and Rocchi. 13 Anaesthetic monitoring included lead II ECG, spirometry, inspired and expired anaesthetic gases and carbon dioxide, pulse oximetry, oscillometric blood pressure measurement and rectal temperature (IntelliVue M60 patient monitor, Philips, Germany). Analgesia was enhanced with intercostal blocks, performed from the second to the seventh intercostal space with a total volume of 1 ml of 0.5% bupivacaine (Carbostein 0.5%, AstraZeneca, Germany).…”
