CIRCULATION OF PRIMARY AND METASTATIC PULMONARY NEOPLASMS

A POSTMORTEM MICROARTERIOGRAPHIC STUDY

Postmortem arteriogr hy and microarteriography were performed in 14 cases of pulmonary metastasis from various primary neoplasms and in 18 cases of primary bronchogenic carcinoma. These studies show that in bronchogenic carcinomas the circulation is predominantly bronchial but that the tumor may be supplied by both the bronchial and the pulmonary circulations.

Pulmonary metastases may be supplied by either the bronchial or the pulmonary circulation separately, or by both simultaneously.

Consistent differences have been demonstrated in the arterial patterns of squamous cell, anaplastic, and adenocarcinoma of the lung. Differences in pattern are also seen between various histologic types of metastasis. These different patterns appear to be related to the histology of these tumors rather than to their growth rate or source of blood supply.
