Chemoport may be associated with complications. These
may arise during or just after insertion or later. Early compli-
cations although uncommon, include pneumothorax, arrhyth-
mias, implanted site infection and bleeding. Late complica-
tions include bloodstream infections, venous thrombosis, pa-
tency impairment, air embolism and catheter fracture [2, 3].
Catheter fracture and embolization is an extremely uncommon
complication with an estimated incidence of less than 1 % in
the literature [1]. The usual site of catheter rupture is in the
space between the first rib and the clavicle. This is the site
where the catheter inside the subclavian vein gets compressed
between the clavicle and the first rib. This was first described
by Aitken and Minton as the “pinch-off sign” [4]. The most
common clinical sign seen with this condition is difficulty in

Learning Points
1. Difficulty in flushing the chemoport and pain are warning
signs.
2. Though uncommon, port fracture is a recognized late
complication of the chemoport.
3. Patient should be promptly investigated for chemoport
fracture.
