BACKGROUND: Distal radial artery access is associated with a low complication rate and infrequently leads to pseudoaneurysm formation. Consequently, the clinical characteristics of pseudoaneurysms in essential thrombocythemia (ET) are not well characterized.
CASE SUMMARY: A 79-year-old woman with ET developed a pulsatile wrist mass 2 weeks after coronary angiography via distal radial artery access. Imaging revealed a 17-mm pseudoaneurysm. Conservative compression was unsuccessful. The initial thrombin injection resulted in partial thrombosis with distal escape and re-entry flow. A subsequent injection with manual proximal radial compression achieved complete thrombosis without complications.
DISCUSSION: In ET, qualitative platelet dysfunction may compromise thrombus stability after thrombin injection. Proximal radial compression is crucial in distal radial pseudoaneurysms to prevent distal escape and achieve durable thrombosis.
TAKE-HOME MESSAGE: Because ET can compromise thrombus stability, sufficient inflow reduction is essential for successful thrombin injection in distal radial pseudoaneurysms.
