A catheter malpositioned patient with pain and paresthesia
Introduction
Central venous catheterization has become very commonand it is a relatively inexpensive and easy method which can be used for several therapeutic and diagnostic purposes like measuring central venous pressure, fluid and blood transfusion, drug administration, hemodialysis and total parenteral nutrition (TPN). It is associated with many potential
complications like other invasive procedures. Malposition as a complication is not a rare occurrence which usually occurs by misdirection of the catheter tip into the major tributaries of the superior vena cava (1). Chest x-ray has an important role in the detection of central venous catheter malposition (2) and it should be done to confirm the position of the catheter tip. In this case report we present a hemodialysis patient in which the catheter tip was malpositioned in the right subclavian vein.

Case report
A 54-year-old female patient (65 kg, 169 cm) who had
undergone hemodialysis several times, came to us because
of the failure of an arteriovenous fistula (AVF) which
was prepared 1 month before admission. The patient had
been treated for end-stage renal disease (ESRD) due to
polycystic kidney disease (PKD) and kidney stones. She
was volume overloaded and because of longstanding use
of peripheral veins for hemodialysis, we have to establish
central venous catheter....
