Patient: Male, 69Final Diagnosis: Atherosclerotic renal artery stenosisSymptoms: NoneMedication: ?Clinical Procedure: ?Specialty: RadiologyObjective:: Unusual setting of medical care Background:: The GuideLiner catheter extension device is a monorail-type ?Child? support catheter that facilitates coaxial alignment with the guide catheter and provides an appropriate back-up force. This device has been developed in the field of coronary intervention, and now is becoming widely applied in the field of endovascular treatment. However, there has been no report on the effectiveness of the guide catheter extension device in percutaneous transluminal renal angioplasty (PTRA). Case Report:: We encountered a case of atherosclerotic subtotal occlusion at the ostium of the left renal artery. Due to the severely calcified orifice and weaker back-up force provided by a JR4 guide catheter, we could not pass any guide-wires through the target lesion. Therefore, we introduced a guide catheter extension device, the GuideLiner catheter, through the guide catheter and achieved good guidewire maneuverability. We finally deployed 2 balloon-expandable stents and successfully performed all PTRA procedures. Conclusions:: The guide catheter extension device can be effective in PTRA for severely calcified subtotal occlusion.
