Stent-induced flow disturbances in the ipsilateral external carotid artery following internal carotid artery stenting: a temporary cause of jaw claudication.

Background: We hypothesize that stenting of the internal carotid artery can immediately impede blood flow to the external carotid artery by either plaque shift or stent coverage of the ostium, and thereby cause ischemic symptoms like ipsilateral jaw claudication.

Methods: Thirty-three patients with high-grade asymptomatic stenosis of the internal carotid artery who underwent endovascular treatment were examined by ultrasound of the external carotid artery and performed an exercise test by chewing chewing gum synchronously to an electronic metronome for 3 min. Tests were performed before, the day after, and 1 week after the stenting procedure.

Vascular puncture site complications - diagnosis, therapy, and prognosis.

The numbers of endovascular procedures have been noted to substantially increase over the past two decades. Besides all the technical advances and the increasing skills of more and more trained interventionists, the vascular access site still offers the possibilities and carries the risk of access site complications, which have not been changed dramatically over the past years. Guidelines on the vascular puncture procedure itself are lacking.

Percutaneous instillation of physiological saline solution for the treatment of femoral pseudoaneuryms.

Objective: To investigate the efficacy of para-aneurysmal saline injection for closure of postcatheterization pseudo-aneurysm (PA) at the vascular access site.

Methods: Fifty-one consecutive patients with postcatheterization PA at the vascular access site were included to undergo percutaneous para-aneurysmal saline injection. In case of technical failure the day after, PA were treated by bovine thrombin injection.
