Rumpel‐Leede phenomenon as a rare complication after transulnar percutaneous coronary angiography and intervention

The Rumpel‐Leede sign, characterized by a non‐blanching petechial rash distal to venous occlusion, has historically been associated with thrombocytopenia and capillary fragility. This phenomenon has been observed in various situations involving pressure application, such as tourniquet tests and continuous non‐invasive pressure monitoring. Here, we present a case of Rumpel‐Leede sign occurring after transulnar percutaneous coronary angiography in a 55‐year‐old female patient with a history of myocardial infarction. The patient had an uneventful recovery, highlighting the benign nature of the rash and the lack of intervention required. This underscores the importance of recognizing this sign and its association with specific procedures.
