Transesophageal Echocardiographic Examination of Left Subclavian Artery Branches

Abstract

This preliminary study demonstrates the feasibility of examining the proximal segments of the branches of the left subclavian artery during probe withdrawal toward the end of a routine transesophageal echocardiographic study. The branches identified most commonly were the vertebral and the internal mammary arteries.

Transesophageal Echocardiographic Detection of Left Vertebral Artery Origin Stenosis

“…[1][2][3][4][5][6][7][8] We discuss a case where severe stenosis at the origin of the LVA was identi ed by TEE and subsequently con rmed by angiography in a patient with stroke. We previously developed a technique in which the neck vessels can be examined at the end of the usual TEE examination during slow probe withdrawal into the upper esophagus and then the pharynx.…”

Transesophageal Echocardiographic Identification of Bilateral Vertebral Artery Ostial Stenosis

“…With the probe positioned in the upper esophagus, aortic arch branches (such as the innominate, common carotid, and subclavian arteries) and the accompanying veins can be well visualized. Branches of the subclavian artery, such as the vertebral and internal mammary arteries, have also been imaged 1–9 . In this report we describe the usefulness of 2D TEE in correctly diagnosing severe ostial stenosis of both the left (LVA) and right vertebral arteries (RVA) in an adult patient with the probe positioned in the upper esophagus.…”

Transesophageal Three‐Dimensional Color Doppler Echocardiographic Reconstruction of the Left Vertebral Artery

“…1 We present a patient in whom we successfully reconstructed a long segment of the proximal left vertebral artery in three-dimensions (3-D) using color Doppler TEE. color Doppler TEE may complement two-dimensional (2-D) TEE by its ability to view cross sections of the left vertebral artery at any desired level from the 3-D data stored in the computer.…”
