Top of Basilar Artery Occlusion Thromboembolism in Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) Treated with Intravenous Thrombolysis and Mechanical Thrombectomy.

Introduction This case report illustrates the complexities of arrhythmogenic right ventricular cardiomyopathy (ARVC) and its thromboembolic complications resulting in top-of-basilar artery syndrome. We discuss the case of a 37-year-old male with ARVC who presented with acute onset of dizziness, imbalance, and vomiting, leading to the diagnosis of a top-of-basilar artery occlusion which was successfully treated. Case presentation This case highlights the diagnostic and acute treatment challenges in basilar artery occlusion (BAO) due to its non-specific symptoms and emphasizes the critical role of CT angiography in detecting occlusive thrombi for timely intervention.
