Vascular injuries are a rare complication after arthroscopic knee surgery. Pseudoaneurysm of the superior lateral genicular artery occurred in a 14-year-old patient after a routine lateral release arthroscopy. The diagnosis was confrmed on a
computed tomography scan with intravenous contrast. An arteriogram also demonstrated the pseudoaneurysm that was
successfully obliterated with microcoils. To our knowledge, this is the frst documented case of pseudoaneurysm of a superior lateral geniculate artery after an entirely arthroscopic knee surgery. Moreover, this is the frst case of pseudoaneurysm
around the knee in a pediatric patient after this procedure. Diagnosis and treatment options of arterial pseudoaneurysms
following knee arthroscopy are discussed
