Novel application of the hemostatic device TOMETA KUN.

A 79-year-old woman was admitted with worsening chest discomfort and diagnosed as having an acute myocardial infarction. She underwent emergency coronary angioplasty via the transradial artery, but during surgery the proximal portion of the radial artery was perforated by a wire injury. The TOMETA KUN compression system (Zeon Medical, Tokyo, Japan) was used for hemostasis at the perforation site and enabled an anterograde flow to be maintained in the radial and ulnar arteries without extravascular leakage. In addition to stabilizing the arterial perforation, the device allowed the successful completion of the percutaneous coronary intervention procedure without the need to cease anticoagulant therapy.
