After successfully inserting and inflating the nanocross balloon, there was a problem in deflating the balloon.Multiple unsuccessful attempts were made with the indeflator and a 10cc syringe to evacuate the contrast out of the balloon.The angiogram still showed that the balloon had contrast in it.At this time, the indeflator was set to 3 atm pressure.The balloon finally showed no contrast and was removed after this.Total inflation time turned out to be over 4 minutes.The procedure was finished by performing atherectomy and a drug-coated balloon inflation.There were no adverse consequences to the patient, and the patient was discharged on the same day without any complaints.The nanocross 0.014in otw pta dilatation catheter was received for evaluation.During investigation, a kink was noticed at approximately the balloon chamber's mid-point.Another kink in the guidewire lumen was also noted just proximal of the proximal balloon bond.The inflated balloon was examined under magnification, and a blockage was noted approximately 0.5cm proximal of the proximal balloon bond.The source of the blockage is unknown.
