We report two patients with spontaneous intrajugular migration of Hick
man catheters which were initially correctly placed with the tip in th
e right atrium, via the right subclavian vein, In one patient the cath
eter remained in situ for 40 days without any sequelae; in the second
patient the catheter was removed immediately, In the first patient two
interim chest radiographs disclosed the catheter's course suggesting
a possible mechanism of migration, Since early detection of this compl
ication allows interventional repositioning, periodic monitoring of in
dwelling catheters by chest X-ray is recommended.
