[Evaluation of tumor vascularization in primary lung cancer by transesophageal color Doppler echography].
A 63 year-old male with primary lung cancer, was examined by transesophageal color Doppler echography (TEE). TEE revealed metastatic lymph node adjacent to the root of the right pulmonary vein. Direct invasion to the left atrium was neglected because of the finding that the left atrial wall was fluctuating according to cardiac movements. TEE also visualized a tumor vessel in which peak velocity of the flow was high, 1m/sec. The resected specimen showed that the tumor vessel had originated from the bronchial artery in the metastatic lymphnode. High velocity flow in the tumor by transesophageal Doppler analysis is highly indicative of malignancy. Doppler analysis in the tumor vessel might be useful in tissue characterization of the lymphnode in primary lung cancer.
