Figure 5.
Locations of thrombus formation (yellow stars) within each patient’s circuit/cannula. A: Patient 1: thrombus formed in inflow lumen of the dual lumen cannula. Limb was clamped and tubing was disconnected from cannula to aspirate thrombus and reestablish flow. B: Patient 2: thrombus formed in inflow lumen/tubing of dual lumen cannula. C: Patient 3: thrombus formed in distal outflow lumen extending from bend in circuit tubing to the outlet in the main pulmonary artery. D: Patient 4: thrombus formed in the bend of circuit tubing flowing to distal outflow lumen.
