Unusual Placement of a Central Venous Catheter in the Left Lung: Case Report

Ver documento

Detalhes bibliográficos
Resumo:Abstract Central venous catheters (CVCs) are widely used in clinical practice, but their unusual misplacement can result in serious complications. We present the case of a 70-year-old male with end-stage renal disease requiring central venous access for hemodialysis. Despite ultrasound-guided insertion, the CVC was inadvertently advanced into the left superior pulmonary vein, leading to the presence of arterialized blood on aspiration. Chest radiography initially suggested an atypical catheter trajectory, and computed tomography confirmed the anomalous connection of the left superior pulmonary vein to the left brachiocephalic vein, consistent with a partial anomalous pulmonary venous drainage. The discussion highlights the imaging findings, differential diagnosis, and clinical implications of mispositioned CVCs in patients with vascular anomalies.
