Prospective Evaluation of Thrombotic Complications After Internal Jugular Vein Cannulation for External Bypass
Authors' conclusion
Although IJV thrombosis was frequent, all cases remained clinically silent.
Study context
- Population
- Patients undergoing internal jugular vein (IJV) cannulation for venous drainage during total cardiopulmonary bypass (CPB) in minimally invasive cardiac surgery, university tertiary hospital
- Participants
- 44 patients
- Outcome
- Ultrasound-detected IJV thrombi
Methodological detailssingle-centre, December 1, 2022, to January 11, 2024
- Single-centre
- December 1, 2022, to January 11, 2024
Main finding
As reported in the abstract
Incidence of ultrasound-detected IJV thrombi
79.5%
Observational data: associations, not effects.
Further findings
Thrombus size by location
- Thrombi at the insertion site smaller than those located distally
Correlation of thrombi with cannula size, intravascular insertion length, CPB duration, body weight
- No correlation with cannula size
- P = 0.886
- No correlation with intravascular insertion length
- P = 0.086
- No correlation with duration of CPB
- P = 0.094
- No correlation with body weight
- P = 0.590
Safety
- Major complications during cannula insertion or removal
- 0
- Patients with clinical symptoms related to IJV thrombi
- 0
