A rare case of a variant of development of a pseudoaneurysm after angiography and stenting of coronary arteries with transradial access

INTRODUCTION: Transradial access in catheterization of the coronary arteries is a safe and widely used approach with significantly lower incidence of serious complications compared with the transfemoral access. Since this is the basic form of access used by interventional surgeons dealing with coronary vessel pathology, awareness of its complications is of much importance. Pseudoaneurysm of the radial artery is a rare complication of transradial access with a typical localization of the defect along the anterior wall of the artery. The most common causes include inadequate compression of the puncture site, systemic use of anticoagulants by the patient or the use of sheaths larger than 6 Fr. Early detection and treatment of this rare complication are of great importance. Aim: To present a clinical case of a patient with a pseudoaneurysm of the radial artery that developed on the first day after injury to the posterior arterial wall. This paper presents a clinical case of a patient with radial artery pseudoaneurysm resulting from injury to the posterior wall of the artery that occurred during puncture and was successfully closed using tight bandaging. CONCLUSION: The clinical case is presented due to its rare frequency of occurrence. A careful puncture of the radial artery without damaging the posterior wall will help avoid the development of this complication of coronary angiography. Compression of the puncture site of the pseudoaneurysm neck under ultrasound control can be an alternative to surgical treatment.
