ABSTRACT OBJETIVO: Descrever a técnica de proteção cerebral usada na angioplastia com colocação de "stent" para tratamento de lesões estenóticas da bifurcação carotídea, mostrando sua eficiência em evitar a embolia durante o procedimento. MÉTODOS: QUAREnta e dois pacientes (47 artérias) foram tratados com a técnica de proteção cerebral que consistiu na oclusão temporária da carótida interna acima da estenose, fazendo-se aspiração e injeção de solução de glicose a 5% na carótida interna após a colocação de "stent" e angioplastia, para remover eventuais fragmentos da placa. RESULTADOS: A angioplastia foi eficiente em todos os casos. Não ocorreu embolia nos pacientes deste estudo nos quais se utilizou a técnica de proteção cerebral na sua versão completa. Embolia ocorreu em um paciente, durante pré-dilatação da estenose, antes de se usar a técnica de proteção cerebral. CONCLUSÃO: A técnica de proteção cerebral foi eficiente em evitar a embolia nos procedimentos realizados. Esses dados concordam com os da literatura e o uso desta técnica amplia as indicações da angioplastia carotídea.

    ABSTRACT: The Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS) is an international multicenter randomized trial, the primary aims of which are: (1) to determine the risks and benefits of carotid and vertebral artery transluminal angioplasty; and (2) to compare these with surgical treatment (carotid endarterectomy) or best medical treatment. Through the end of October 1995, 193 patients have been randomized (90 at our center). In this article, the rationale for the trial, its design and protocol, and the experience of our institution within the trial will be discussed.

    ABSTRACT: Carotid endarterectomy has been established as the standard treatment for high-grade carotid stenosis. The results of an ongoing prospective trial for the safety of percutaneous angioplasty with stenting (PTAS) were compared to retrospectively reviewed patients treated with carotid endarterectomy (CEA). During the same 14-month period, 273 patients underwent treatment of 310 carotid bifurcation stenoses: 107 by PTA with stenting, 166 by CEA. Indications for treatment included stroke 46 (16.8%), transient ischemic attack 109 (39.9%), syncope 7 (2.6%), and high-grade asymptomatic stenosis 111 (40.7%). Combined early stroke and death rates are listed as follows: [table: see text] Important nonneurologic complications were evident in six (5.6%) PTAS patients and two (1.2%) CEA patients. Six-month follow-up data was available for 193 patients (71%) with the following results: seven (6.5%) minor strokes in the PTAS group, one (0.6%) minor stroke in the CEA group, one (0.9%) major stroke in the PTAS group, one (0.6%) major stroke in the CEA group, four deaths (3.7%) in the PTAS group, and six deaths (3.6%) in the CEA group. Early results from PTA with stenting are promising but not safer than CEA for the treatment of carotid artery stenosis. Long-term follow-up is needed to determine the ultimate durability of this new technique. PTA with stenting may be an alternative for the treatment of carotid bifurcation lesions in selective high-risk surgical patients.

    ABSTRACT: To study the feasibility and safety of carotid angioplasty and stenting using a new cerebral protection device that temporarily occludes the distal internal carotid artery (ICA). Forty-eight high-risk patients (39 men, mean age 69.1 +/- 8 years, range 54 to 86) with 53 ICA stenoses underwent percutaneous angioplasty and stenting via the femoral approach under cerebral protection afforded by a 0.014-inch GuardWire balloon occlusion device. Mean stenosis was 82.1% +/- 9.65% (range 70 to 96) and mean lesion length was 16.0 +/- 7.5 mm (range 6 to 50). Thirty-three (62%) lesions were calcified, and 38 (72%) were ulcerated. Thirty-two (60%) of the lesions were asymptomatic. With the occlusion balloon inflated in the distal ICA, the lesion was dilated and stented. The area was cleaned by aspiration and flushed via an aspiration catheter advanced over the wire. Blood samples were collected from the external carotid artery (ECA) and analyzed to measure the size and number of particles collected. Computed tomography and neurological examinations were performed the day after the procedure. Immediate technical success was achieved in all patients with the implantation of 38 Palmaz stents, 8 Expander stents, and 11 Wallstents. Carotid occlusion was well tolerated in all patients but 1 who had multiple, severe carotid lesions and poor collateralization. Mean cerebral flow occlusion time was 346 +/- 153 seconds during predilation and 303 +/- 143 seconds during stent placement. Total mean flow occlusion time was 542 +/- 243 seconds. One immediate neurological complication (transient amaurosis) occurred in a patient who had an anastomosis between the external carotid (EC) and ICA territories. Debris was removed in all patients with a mean 0.8-mm diameter catheter. Cerebral protection with the GuardWire device is easy, safe, and effective in protecting the brain from cerebral embolism. Larger studies are warranted.
