Infection by Angiostrongylus

Last edited: 4/23/2026

Overview

Angiostrongylus vasorum infection, commonly affecting dogs, can lead to severe vascular complications including arterial rupture, as evidenced by a case where femoral artery rupture contributed to the dog's death 1.

Diagnosis

  • Clinical signs may include hemorrhagic diathesis, weight loss, and neurological symptoms 1.
  • Definitive diagnosis typically involves fecal examination for larvae or post-mortem identification of adult worms in affected tissues 1.
  • Serological testing can aid in diagnosis but is not definitive without parasitological confirmation 1.

    • Management

  • Anthelmintic treatment with fenbendazole is recommended for adult dogs, though specific dosing details are not provided in the abstract 1.
  • Supportive care focusing on managing hemorrhage and addressing concurrent deficiencies is crucial 1.
  • Monitoring for complications such as arterial rupture necessitates close clinical observation 1.

    • Special Populations

  • No specific data provided regarding infection in pregnant, pediatric, elderly dogs, or those with comorbidities 1.

    • Key Recommendations

  • Perform post-mortem examination in suspected fatal cases to identify A. vasorum involvement in vascular complications (Evidence: Weak 1).
  • Initiate anthelmintic therapy with fenbendazole for confirmed cases of Angiostrongylus vasorum infection (Evidence: Expert opinion 1).
  • Closely monitor infected dogs for signs of hemorrhagic events, particularly in critical areas like femoral arteries (Evidence: Expert opinion 1).
