Introduction

  • Cause: trauma (pulmonary contusion Lung: contusion ); coagulopathies, eg warfarin poisoning, thrombocytopenia.
  • Signs: respiratory distress varying in degree with extent of hemorrhage; cough (hemoptysis if severe); concurrent traumatic injuries including flail chest; severe blood loss may result in shock.
  • Diagnosis: history, clinical signs and physical examination, puse oximetry, radiography, clinicopathologic tests of coagulation and oxygenation.
  • Treatment: supportive and symptomatic, manage underlying cause.
  • Prognosis: generally good with appropriate management, ultimately depends on underlying cause.

Pathogenesis

Etiology

Predisposing factors

General
  • Farm dogs - exposure to rodenticides, lungworm paratenic hosts.
  • Dogs that are allowed to run free (trauma).

Pathophysiology

  • Coagulopathy→ intrapulmonary hemorrhage.
  • Metastatic/invasive neoplasia→ invasive destruction of blood vessels → bleeding into lung → hemoptysis and pleural bleeding.
  • Pulmonary contusion→ crush and shearing injury to lung capillaries → bleeding.
  • Pulmonary infarction→ necrosis of blood vessels.
  • ARDS→ severe pulmonary inflammation and capillary vascular leak syndrome.

Timecourse

  • Usually acute, variable.
