Grade | Description |
|---|---|
(a) CIRSE classification system for complications in IR | |
1 | Complication during the procedure which could be solved within the same session; no additional therapy, no post-procedure sequelae, no deviation from the normal post therapeutic course |
2 | Prolonged observation including overnight stay (as a deviation from the normal post-therapeutic course < 48 h); no additional post procedure therapy, no post procedure sequelae |
3 | Additional post procedure therapy or prolonged hospital stay (> 48 h) required, no post procedure sequelae |
4 | Complication causing a permanent mild sequela (resuming work and independent living) |
5 | Complication causing a permanent severe sequela (requiring ongoing assistance in daily life) |
6 | Death |
(b) SIR classification of complications | |
Minor Complications | |
A | No therapy, no consequence |
B | Nominal therapy, no consequence; includes overnight admission for observation only |
Major Complications | |
C | Require therapy, brief hospitalization (< 48 h) |
D | Major therapy, unplanned increased level of care, prolonged hospitalization (> 48 h) |
E | Permanent sequelae |
F | Death |
