RESUMO
Knee arthroscopy is among the most popular surgical procedures performed worldwide. Following knee arthroscopy, complications are infrequent, with vascular damage being extremely rare. We present a case of a 16-year-old man with a superior lateral genicular artery pseudoaneurysm of his right knee. The pseudoaneurysm developed after arthroscopic irrigation and debridement for septic arthritis following previous arthroscopic meniscal repair. Diagnosis was confirmed by computed tomography angiography and the patient underwent intravascular embolization. We conducted a literature review to demonstrate the incidence of vascular injuries following knee arthroscopy, vessels that are more at risk, clinical presentation and current treatment options. Although vascular injuries following knee arthroscopy are uncommon, high clinical suspicion can lead to early detection and treatment of this severe complication.
