Pulmonary Arteriovenous Malformation Presenting With Acute Dyspnea: A Case Report.

Key Points

The research aims to illustrate the diagnosis and management of a rare pulmonary arteriovenous malformation causing acute dyspnea.
Patient presented with acute dyspnea and low oxygen saturation in the emergency department.
Computed tomographic pulmonary angiography identified a 2.5-cm vascular lesion.
Video-assisted thoracoscopic surgical resection was performed to resolve symptoms.
The vascular lesion was confirmed to connect the right inferior pulmonary artery to the left cardiac atrium.
Post-surgery, the patient's respiratory symptoms resolved completely.
The case highlights the significance of imaging in diagnosing rare vascular anomalies.

Abstract

A 65-year-old male presented to the emergency department with acute dyspnea and critically low oxygen saturation (77%), which led to the discovery of an unusual pulmonary arteriovenous malformation (PAVM). Computed tomographic pulmonary angiography revealed a 2.5-cm vascular lesion connecting the right inferior pulmonary artery to the left cardiac atrium, resulting in significant right-to-left shunting. The patient's respiratory symptoms resolved completely after video-assisted thoracoscopic surgical resection, demonstrating the value of comprehensive imaging in diagnosing rare vascular anomalies. This case highlights the clinical significance of unexpected vascular malformations in older adults.
