Spontaneous rupture of chemotherapy catheter diagnosed using chest X-ray oblique projections: An interventional radiology approach

A case of percutaneous retrieval of a catheter without a free end that was fractured during a totally implantable venous access port removal

“…There have been many reports of catheter deviation and injury [3] , [4] , [5] , [6] , [7] , [8] , [9] in TIVAP implants despite their reported safety and convenience. Hinke et al.…”

“…Hinke et al. [10] reported pinch-off syndrome (POS), in which the catheter is fractured between the clavicle and the first rib when placed via the subclavian vein, since then, many similar cases have been reported [3 , 8 , 9] . The internal jugular vein is considered safer than the subclavian vein for TIVAP placement [11] , but several reports of fractured TIVAP catheters inserted through the internal jugular vein exist [4 , 6 , 7] .…”

“…After forming the guidewire exiting the body on both the left subclavian vein and the right femoral vein sides, we inserted the microsnare via the cobra catheter lumen near the FC using the same method as in Figures 3 B and 3 C, and tried to catch the FC, but because the adhesion was so strong, the FC had no free ends and we failed. Snares are often used to retrieve foreign bodies in blood vessels [ [4] , [5] , [6] , [7] , [8] , [9] , 16] and are simple and easy to use, with a high success rate of removal [14 , 18] . However, it is difficult to catch foreign bodies without a free edge [14] .…”
