In this case both Profit Plus 6 Fr RU and Profit plus 6 Fr JR 4.0
(advancing from right radial artery access) guide catheter were kinked
in her tortuous right axillary artery during PCI.
Kinked catheters are thought to be the cause of artery injury that
causes intramural hematoma. It has been reported that hematoma is often
absorbed and dissipated spontaneously. However, in this case, the
hematoma did not decrease and the true lumen was pressed upon.
It has been reported that the use of Amplatz-shaped catheters is a risk
factor for catheter-induced coronary artery
dissection(4), but the association between the type of
catheter and artery injury in the upper limb is still unclear.
The JR catheter is preferred for operability; however, severe vessel
tortuosity may be complicated by axillary artery occlusion(5). Arterial tortuosity is associated with older age,
female sex, high blood pressure, and other cardiovascular risk
factors(6). For such cases, an operator should never
push against resistance or cause excessive catheter
torqueing(7). Prompt changes in arterial access should
also be considered to prevent iatrogenic catheter-inducing
complications.
