血液透析患者冠心病介入治疗可行性初探

目的　探讨尿毒症血液透析患者进行冠状动脉造影及介入治疗的可行性及近期疗效。方法　对 3例频发心绞痛的血液透析患者在适当水化和强化透析基础上 ,应用非离子型造影剂行冠状动脉造影术。结果　单支病变 2例 ,双支 (多处 )病变 1例。分别于造影后 4～ 7日行支架置入术 ,成功置入 1～ 4个支架。术后临床随访 12～ 18个月 ,患者心绞痛症状明显缓解或消失 ,肾功能无恶化。结论　对血液透析患者行冠状动脉造影及介入治疗是安全可行的。

Percutaneous coronary intervention in uremic patients on hemodialysis

Objective To evaluate the safety and possibility of coronary intervention in uremic patients on dialysis. Methods Three uremic patients with unstable angina pectoris were treated successfully with percutaneous transluminal coronary angioplasty and stenting. In order to minimize the adverse effect on kidney due to contrast, non-ionic and low osmolar contrast medium was used and coronary angiography and intervention therapy were performed separately. Further protection of the renal function was effected by more frequent dialysis and increasing fluid administration. Results Coronary contrary shows the stenosis of multiple vessels in one patient, unique vessel lesion in two patients. One to four stents were placed. Clinical follow-up period of 12-18 months after procedure, angina pectoris disappeared in all three patients and no deterioration of renal function was noted. Conclusion It is possible to perform coronary angiography and stenting in uremic patients on hemodialysis successfully and safely, provided due attention was paid to the choice of contrast medium and protective measures for renal function.
