Popliteal vein aneurysm causing pulmonary embolus
J. J. Gallagher and J. H. Hageman
A case of pulmonary embolus arising from a popliteal vein aneurysm is
reviewed. These aneurysms are believed to be developmental in origin; with
the exception of embolic phenomenon, these venous anomalies are generally
asymptomatic. To our knowledge, only six cases have been previously
reported. Physical examination was not helpful, and noninvasive studies
were of no value in detecting the aneurysm. Venography was the only
reliable diagnostic test. Because popliteal vein aneurysms are a potential
source of emboli, surgical intervention is recommended. Venous
aneurysmorrhaphy or excision of the aneurysm with a venous bypass are the
surgical procedures most often carried out. Aneurysmorrhaphy appears to be
associated with an unacceptably high rate of thrombosis; excision with
placement of a vein graft may be a more satisfactory alternative.
