[Pseudoaneurysms after carotid endarterectomy].
Pseudoaneurysms after TEA of the internal carotid artery are one of the rarest and most severe complications of this form of surgery. Their etiology appears to depend on 3 causes: a suturing defect due to technical errors made by the surgeon or to the incorrect choice of threads; an infections, and lastly the arterial wall weakened by TEA. The patch increases the risk of false aneurysm approximately four fold. We therefore agree with other authors that, in spite of the undoubted value of the patch in the prevention of restenosis, it must only be used in the presence of an internal carotid of small diameter (less than 4 mm). Contrary to what is reported in the literature we performed both these operations under loco-regional anesthesia and a detailed knowledge of this method allows is to be performed on the carotid axis. Only through a careful follow-up of all the carotids operated can the small dilations which often do not require surgical treatmente identified. The two cases reported here were treated by the removal of the pseudoaneurysms and its replacement with a prosthesis in one case and with the vena saphena in the other. Both were monitored with clinical examination and echo-Doppler and no recidivation has been reported to date.
