Q

Tinga, Vet Surg, 2015:
Extraluminal rings vs intraluminal stents

  1. Mortality rates for extraluminal rings vs intraluminal stents?
  2. What was associated with a shorter survival time?
  3. Major complication rates for extraluminal rings vs intraluminal stents?
  4. Which procedure resulted in more good or excellent outcomes?
  5. What % of dogs developed post-op laryngeal paralysis after extraluminal rings vs intraluminal stents?
A

Tinga, Vet Surg, 2015:

  1. Mortality rates: 8% for extraluminal rings vs 0% for intraluminal stents
  2. Dogs with mainstem bronchial collapse had a 5 times shorter survival time
  3. Major complication rates: 42% for extraluminal rings vs 43% for intraluminal stents
  4. Extraluminal rings had more good or excellent outcomes (80%) than intraluminal stents (28%)
  5. Post-op laryngeal paralysis occurred in 15% after extraluminal rings vs 3% after intraluminal stents
