Grade 1 catheter changes were common (33%) among control subjects, but grades 2 and 3 were uncommon (1%); catheter fracture or fragmentation occurred in 2 of 5 cases with long-term grade 2 pinching.

Overview

Grade 2 pinch-off may signal fracture risk in subclavian devices; leaves open whether routine grading improves outcomes.

Structured PICO

What are the radiological grades and clinical significance of pinch-off syndrome in patients with implantable subclavian venous access devices?

Population

133 patients with implantable subclavian venous access devices, comprising 11 patients with pinch-off syndrome (POS), 22 matched control patients, and 100 consecutive routine clinic patients.

Intervention

Implantable central venous access devices placed via the subclavian vein

Comparator

Matched control patients and routine clinic patients without POS

Outcome

Catheter grade (0 = normal, 1 = abrupt change in course with no luminal narrowing, 2 = luminal narrowing, and 3 = complete catheter fracture)safety

Grade 2 catheter compression (luminal narrowing) in subclavian venous access devices represents significant compression with potential for serious complications like fracture, whereas Grade 1 is of uncertain clinical significance.
