Use of tandem stents for treatment of helicoidal dissection of the right coronary arteryDOI: 10.1590/S0066-782X2000000600004 Abstract: coronary dissection occurs frequently and in several degrees during coronary angioplasty, which is one of the mechanisms for increasing the lumen diameter of a vessel. however the length of the dissection may affect the procedure, becoming the most frequent cause of total occlusion after coronary angioplasty. we report here a case of extensive dissection that occurred during the coronary angioplasty of a focused lesion, which we treated with two long stents.
