Incidental detection of persistent left superior vena cava during Permcath insertion: a case report.
Pak J Radiol Jan ;33(3):168-70.

Persistent left superior vena cava (PLSVC) is an uncommon congenital venous anomaly that is often diagnosed incidentally during procedures involving central venous access, such as pacemaker or permcath insertion. We present the case of a 60-year-old male with end-stage renal disease who had an incidental finding of PLSVC during permcath placement for hemodialysis. Recognition of this venous anomaly enabled successful procedural completion despite the unexpected anatomy. This case underscores the importance of considering congenital venous abnormalities as potential causes when technical difficulties arise during central catheterization procedures.
