Lungworm: why do some dogs bleed?

Coagulation status in dogs with naturally occurring Angiostrongylus vasorum infection

by Sophie Adamantos, Sophie Waters and Amanda Boag

TEG: diagnostic technique

Thromboelastography (TEG) is a newer technique that provides a global assessment of coagulation. It assesses the influence of both primary and secondary coagulation on blood clotting and can also be used to identify hypercoagulability ...

Low fibrinogen

In the study, fibrinogen concentration was lower in those with bleeding diatheses (median 3.18 mmol/L, range 0.44–26.31), compared with those without (median 16.02 mmol/L, range 1.32–26.02) (P=0.026). This table summarises these findings. ...

Bleeding dogs


While the coagulopathy associated with

Angiotrongylus vasorum infection has been clinically recognised for some time, published information is limited. The aim of the current study was to describe the haemostatic abnormalities seen in dogs diagnosed with naturally occurring A. vasorum infection in an endemic area of England through evaluation of traditional and global coagulation tests including thromboelastography. ...

Objectives: Angiostrongylus vasorum infection is associated with bleeding tendencies in approximately one-third of clinical cases. The cause of the coagulopathy is poorly understood but may be related to disseminated intravascular coagulation. Thromboelastography is a global evaluation of coagulation and has not been described in a cohort of dogs with this disease.

Materials and Methods: Thromboelastography in association with other measures of coagulation including prothrombin and ...

Angiostrongylus vasorum

Angiostrongylosis is a clinical syndrome of dogs caused by infection with Angiostrongylus vasorum, the 'French heartworm' or 'lungworm'. The adult worms accumulate in the pulmonary ...
