Table 4.
Relationship among collateral vessel origin, pulmonary destination, and clot burden
Pulmonary artery destination | Total occlusion of main pulmonary artery | Jamieson type of lesion on ipsilateral lung | ||||
---|---|---|---|---|---|---|
Collateral origin | Left | Right | 1 | 2 | 3 | |
RCA (n = 18) | 3 | 15 | 4 | 9 | 7 | 2 |
LCx (n = 12) | 4 | 8 | 4 | 9 | 2 | 1 |
LAD (n = 1) | 1 | 0 | 0 | 0 | 1 | 0 |
PL (n = 3)a | 3 | 1 | 1 | 0 | 3 | 1 |
RCA: right coronary artery; LCx: left circumflex artery; LAD: left anterior descending artery; PL: posterolateral branch of the RCA.
One collateral arising from the PL traveled to both the left and the right pulmonary artery.
