Clinical Information

Relevant Clinical History and Physical Exam

72 years old lady with background history of coronary artery disease, hypertension, dyslipidaemia, allergic rhinitis, dyspepsia presented with reduced effort tolerance for 3 months. Denies chest pain, lower limb swelling or paroxysmal nocturnal dyspnea. NYHA 2. No cardiac murmur, no crepitations, normal jugular venous pressure and no pedal edema on examination. 

Relevant Test Results Prior to Catheterization

Creatinine 78 eGFR 65, TroponinT 6, proBNP 64 pg/mlEchocardiogram showed Ejection Fraction 53%, with hypokinesia mid and basal posterior, basal septal, mid and basal inferior segments.A PET-CT Cardiac showed moderate area of non-transmural infarcted myocardial segments with a small area of peri-infarcted stress induced ischaemia in the left circumflex/ right coronary artery territories. A diagnostic coronary angiography was performed in view of PET-CT Cardiac findings


Relevant Catheterization Findings

Coronary angiography showed complete total occlusion of right posterior left ventricular branch with collaterals from left system and moderate disease of first diagonal.


Interventional Management

Procedural Step

Right radial pulse was not strong. Ultrasound revealed a small right radial artery. Decided for left radial artery approach. Single puncture successful with ultrasound guidance. Optitorque 5FR catheter. Left coronary angiogram images obtained.
While attempting to engage right coronary artery, noted loss of pressure.
Catheter kinked in a figure of 8 position around left subclavian area. 
Attempted to unkink by untwisting with 0.035" J tip guidewire support of failed.
Kinked part of catheter brought down to left arm area and attempted to unkink with inflated cuff and compression was not successful as well.
Right femoral puncture and  Snare Amplatz Goose Neck 20mm advanced to distal tip of catheter.
Distal tip of catheter was snared and manage to unkink catheter.
Optitorque 5FR catheter successfully removed from left radial sheath.
Right femoral closed with Perclose Prostyle 6FR.
Patient was observed overnight without any complications and discharged well the following day.

Case Summary

This case highlights severe kinking of a radial guiding catheter as an important complication of transradial intervention. Recognition of resistance and poor torque response should alert the operator for early catheter withdrawal. Percutaneous snaring is a safe and effective retrieval strategy after failure of other maneuvers that avoids surgical intervention. Operator awareness of catheter behaviour, torque control and escalation of retrieval techniques are of the utmost importance to ensure procedural safety and also to preserve radial access integrity.
