Comparative Analysis of Ultrasound Diagnosis and Pathological Characteristics of External Jugular Venous Aneurysm

Abstract

Purpose: This study aimed to investigate the diagnosis of the external jugular venous aneurysm on color Doppler ultrasound and its relationship with pathological characteristics. Methods: A retrospective analysis of 17 patients with external jugular venous aneurysm admitted to the Provincial Hospital Affiliated with Shandong First Medical University from May, 2010, to June, 2020, was performed. The color Doppler ultrasound characteristics of 17 patients with external jugular vein aneurysms were analyzed and summarized, which were then compared with postoperative pathological outcomes. Results: All 17 patients with external jugular venous aneurysms were presented with cystic structures adjacent to and communicated with the external jugular vein. Color Doppler flow imaging showed a bidirectional venous flow signal in the communication between the cystic structure and the external jugular vein. Among the 17 patients, ultrasound diagnosis showed true venous aneurysm due to degenerative changes in the venous wall in 8 cases, venous pseudoaneurysm in 4 cases, and external jugular venous aneurysm in 5 cases, and postoperative pathology indicated degenerative changes in the venous wall in all 17 patients. Conclusion: Bidirectional blood flow at the communication between the cystic lesion and the external jugular vein on color Doppler ultrasound should not be the criterion for the diagnosis of external jugular venous pseudoaneurysm, which requires pathological support.
