Embolic Signals

We investigate the safety and/or risk of PTA for vertebral and subclavian artery stenosis by monitoring embolic signals using transcranial Doppler (TCD) ultrasonography. Twelve consecutive patients undergoing PTA for subclavian and vertebral artery stenosis of atherosclerotic origin were studied. Before, during and after PTA, TCD monitoring was performed to detect embolic signals for 30 minutes at each time. No embolic signals were detected in any patient before angioplasty. During angioplasty, one embolic signal was detected immediately after balloon deflation in one of 12 patients. Several embolic signals were detected after the procedure in six of 12 patients, but thereafter embolic signals became less frequent in number. Three days after angioplasty, embolic signals were not detected in any patient. TCD monitoring could be a useful modality for detection of microemboli during and after PTA in the posterior circulation. Our present study suspected that subclinical microemboli are released from the dilated vessels for three days after vertebral and subclavian PTA and anticoagulant or antiplatelet therapies may prevent embolic complications after the procedure.

Percutaneous Transluminal

Percutaneous transluminal angioplasty (PTA) and stenting has recently been proposed as an alternative to surgical reexploration in patients with recurrent carotid artery stenosis following endarterectomy. The authors retrospectively reviewed their experience after performing 25 procedures in 21 patients to assess the safety and efficacy of PTA with or without stenting for carotid artery restenosis. The mean interval between endarterectomy and the endovascular procedure was 57 months (range 8-220 months). Seven arteries in five patients were treated by PTA alone (including bilateral procedures in one patient and repeated angioplasty in the same vessel in another). Early suboptimum results and recurrent stenosis in some of these initial cases prompted the authors to combine PTA with stenting in the treatment of 18 arteries over the past 3 years. No major periprocedural deficits (neurological or cardiac complications) or death occurred. There was one periprocedural transient neurological event. A pseudoaneurysm of the femoral artery (at the access site) required surgical repair. In the 16 patients who each underwent at least 6 months of follow-up review, no neurological events ipsilateral to the treated artery had occurred after a mean follow-up period of 27 months (range 6-57 months). Three of five patients who underwent PTA alone developed significant (> 50%) asymptomatic restenoses that required repeated angioplasty in one and PTA with stenting in two patients. Significant restenosis (55%) was observed in only one of the vessels treated by combined angioplasty with stenting. Endovascular PTA and stenting of recurrent carotid artery stenosis is both technically feasible and safe and has a satisfactory midterm patency. This procedure can be considered a viable alternative to surgical reexploration in patients with recurrent carotid artery stenosis.
