Imaging findings associated with costoclavicular intervention during lead extraction
Authors' conclusion
Computed tomography captures details of costoclavicular binding that appear to correlate with the need for adjunctive extraction techniques, including surgical intervention.
Study context
- Population
- Patients undergoing transvenous lead extraction with preprocedural multidetector computed tomography (MDCT)
- Participants
- 56 patients
- Comparison
- Patients requiring costoclavicular intervention vs matched controls without intervention
- Sub-C onlyn = 20
- Surgical interventionn = 8
- Matched controlsn = 28reference
- Outcome
- Preprocedural MDCT findings (lead tethering to bone, adjacent calcification) associated with need for costoclavicular intervention
Methodological detailsage- and sex-matched controls
- Age- and sex-matched controls
Main finding
As reported in the abstract
Costoclavicular intervention rate by MDCT pattern
Lead surrounded 360° by fat
5 of 24
5 events
Lead tethered to bone by <180°
11 of 19
11 events
No tethering, with calcifications
3 of 4
3 events
Lead tethered to bone by >180°
9 of 9
9 events
- Tethering of ≥1 lead to bone by >180°: costoclavicular intervention rate
- 100%
- Tethering of ≥1 lead to bone by >180°: surgical intervention rate (highest)
- 56%
- No bone tethering: surgical intervention rate
- 0%
