A 1-year-old oriental cat was presented with a peracute onset of tetraparesis and vocalisation. Clinical findings were suggestive of multi-site thromboembolic disease, and this was confirmed on post-mortem examination. An echocardiogram showed severe restrictive cardiomyopathy and spontaneous echogenic contrast. To the author's knowledge, this is the first reported case of tetraparesis secondary to cardiogenic arterial thromboembolic disease. Thromboembolic disease should be included as a differential diagnosis for any cat presented with a peracute onset of paresis or paralysis, even if there is no history of cardiac disease.

Pulmonary vascular diseases, particularly when accompanied by pulmonary hypertension, are complex disorders often requiring multimodal imaging for diagnosis and monitoring. Echocardiography is the primary screening tool for pulmonary hypertension, while cardiac MR imaging (CMR) is used for more detailed characterization and risk stratification in right ventricular failure. Chest computed tomography (CT) is used to detect vascular anomalies and parenchymal lung diseases.

Endovascular intervention is a safe, effective treatment modality in the management of diverse pulmonary vascular pathologies, including acute or chronic thromboembolic disease, pulmonary arteriovenous malformations (pAVMs), pulmonary artery or bronchial artery hemorrhage, and foreign body retrieval. This article reviews indications, contraindications, techniques, and outcomes in endovascular management of common pulmonary vascular pathologies, with the goal of improving operator familiarity and facility with these procedures.

Cardiac MR imaging and pulmonary MR angiography (MRA) are important clinical tools for the assessment of pulmonary vascular diseases. There are evolving noncontrast and contrast-enhanced techniques to evaluate pulmonary vasculature. Pulmonary MRA is a feasible imaging alternative to CTA in pulmonary embolism detection.

Chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary hypertension secondary to chronic obstruction of pulmonary arteries by organized thromboemboli. Echocardiography and Echocardiography and ventilation/perfusion (V/Q) scan are the initial screening examinations for CTEPH; the diagnosis is often missed on computed tomography (CT). Imaging findings of chronic thromboembolic pulmonary disease overlap with those of acute pulmonary embolism, and radiologists should evaluate for the presence of concurrent chronic disease in all cases of acute pulmonary embolism detected on CT pulmonary angiography.

Pulmonary hypertensive changes are commonly seen by the surgical pathologist, but the majority represents secondary changes due to some process extrinsic to the lung. Some primary, or idiopathic, vascular diseases result in unique pathologic changes including the plexiform lesion and venous hypertensive changes. Thromboembolic disease also shows unique pathologic features.
