Abstract
OBJECTIVES: Reducing the rate of postoperative stroke after cardiac surgery remains challenging, especially in patients with occlusive cerebrovascular disease. Angioplasty in all patients with high-grade carotid artery stenosis has not been shown to be effective in reducing the post-surgical stroke rate. In this study, we present the initial results of a different approach using selective carotid angioplasty only inpatients with poor intracranial collaterals.
METHODS: We conducted a single-centre study to assess the safety of this procedure. The postangioplasty complication rate of the study group was compared to that of patients who were scheduled for symptomatic carotid artery angioplasty. To determine the effectiveness of this procedure, the post-cardiac surgery complication rate of the study group was compared with that of the matched case controls.
RESULTS: Twenty-two patients were treated with selective carotid angioplasty without developing persistent major neurological complications.All patients except 1 patient subsequently underwent surgery without developing persistent major neurological disabilities. Two patients died of cardiogenic shock within 30 days.
CONCLUSIONS: Selective carotid angioplasty prior to cardiac surgery in patients with a presumed high risk of stroke was relatively safe and effective in this study group. Although this strategy does not prevent stroke in these high-risk patients, data suggest that this approach shifts the postoperative type of stroke from a severe haemodynamic stroke towards a minor embolic stroke with favourable neurological outcomes. Larger studies are needed to determine whether this strategy can effectively eliminate the occurrence of haemodynamic strokeafter cardiac surgery.

摘要：
目的：降低心臟手術后的中風發(fā)生率仍然具有挑戰(zhàn)性，尤其是對于閉塞性腦血管疾病的患者。尚無所有高級別頸動脈狹窄患者的血管成形術能有效降低術后卒中發(fā)生率。在這項研究中，我們僅針對顱內側支較差的住院患者，介紹了使用選擇性頸動脈血管成形術的另一種方法的初步結果。
方法：我們進行了單中心研究，以評估該程序的安全性。將研究組的血管成形術后并發(fā)癥發(fā)生率與計劃進行有癥狀的頸動脈血管成形術的患者進行比較。為了確定該方法的有效性，將研究組的心臟手術后并發(fā)癥發(fā)生率與配對病例對照進行了比較。
結果：22例患者接受了選擇性頸動脈成形術治療，未出現(xiàn)持續(xù)的主要神經(jīng)系統(tǒng)并發(fā)癥;除1例患者外，所有患者均接受了手術，未出現(xiàn)持續(xù)的主要神經(jīng)系統(tǒng)疾病。兩名患者在30天內死于心源性休克。
結論：在本研究組中，假定為中風的高風險患者，在心臟手術前進行選擇性頸動脈血管成形術相對安全有效。盡管這種策略不能在這些高危患者中預防中風，但數(shù)據(jù)表明，這種方法將中風的術后類型從嚴重的血流動力學中風轉移到了輕度栓塞性中風，具有良好的神經(jīng)功能。需要更大的研究來確定這種策略是否可以有效消除心臟手術后血液動力學中風的發(fā)生。（譯文來自GOOGLE)
