“…13 To minimize the time of blood extravasation to the pericardium and increase the speed of the device exchange, the puncture of another arterial site, with subsequent catheterization of the same coronary artery, can be used, known as the doubleguide catheter technique, commonly used when there is a need to implant a covered stent. 9,10 In the case reported here, after identifying the perfora tion of the coronary artery, classified as Ellis type II, it was initially decided to occlude the perforation, using prolon ged inflation of a balloon catheter, but without success. It was then decided to occlude the lesion segment by implan ting another stent, using a double guide catheter technique.…”
