Carotid angioplasty with stenting in post-carotid endarterectomy restenosis.

Recurrent stenosis post-carotid endarterectomy (CEA) is not a solitary or unusual phenomenon. Compared to the initial CEA, the reoperation is often more technically challenging and frequently results in local and neurological complications. Carotid artery angioplasty with stenting (CAS) is currently being investigated as an alternative to carotid endarterectomy. In our study, ninety-nine patients underwent CAS in 110 arteries. Procedural success was 99% (109/110). Our results show that CAS treatment in post-CEA restenosis, especially with improved technique and distal protection, is safe with a low neurological complication rate, without any "local" complications and without any cranial nerve palsies. This study suggests that the future primary mode of treatment of post-CEA restenosis might be carotid stenting rather than surgery.

Carotid artery stenting: technical considerations.

BACKGROUND AND PURPOSE: Carotid endarterectomy (CEA) is one of the most frequently performed operations in the United States. To offer patients a less invasive means to achieve the same goal, carotid artery stenting (CAS) is investigated as an alternative treatment to CEA. METHODS: Three hundred ninety patients underwent CAS, with 451 vessels treated. CAS was performed using a coaxial system with a 7F 90-cm sheath for predilation, stent placement, and stent dilation. Pretreatment antiplatelet therapy was administered. We currently practice same-day admissions and 23-hour discharges. RESULTS: The technical success rate was 98%. The 30-day mortality/morbidity rates were as follows: death, 1.7% (two [0.5%] neurologic and five [1.2%] systemic] major strokes, 0.9% (two of four were related to the intervention); minor strokes, 5.5%. Among 25 patients who suffered minor strokes, 14 achieved complete recovery. On an annual basis, the incidence of minor stroke declined from 6.8% (1994-1995), to 5.8% (1995-1996), 5.3% (1996-1997), and then 4% (1997-1998), with no major strokes or neurologic deaths occurring during the 1997 to 1998 period. CONCLUSION: CAS is an effective treatment for carotid stenosis. With proper selection of patients and meticulous technique, complication rates compare favorably with those of CEA.

Outpatient carotid artery stenting: a case report.

PURPOSE: To report a case of carotid artery stenting for asymptomatic carotid restenosis performed in an outpatient setting. METHODS AND RESULTS: A 68-year-old man with right carotid restenosis after repeat carotid endarterectomy underwent carotid angioplasty and stenting on an ambulatory basis. The procedure to implant a Smart stent required 45 minutes; the femoral access site was closed with a puncture closure device. The patient experienced no sequelae to this procedure and is well 6 months after treatment. CONCLUSIONS: Outpatient delivery of percutaneous carotid stenting may be feasible in appropriately selected patients.
