Table 3. True Positive and False Positive Diagnosis of Hepatic Artery Occlusion in 64 Patients with Anastomosis Site Abnormality Divided into Subcategories.
| Anastomosis Site Abnormality Subcategories | True Positive | False Positive | |
|---|---|---|---|
| Cutoff (n = 31) | |||
| Cutoff anastomosis abnormality with distal run-off abnormality (n = 29) | 27 (93.1) | 2 (6.9) | |
| Cutoff anastomosis abnormality without distal run-off abnormality (n = 2) | 1 (50.0) | 1 (50.0) | |
| Focal stenosis (n = 20) | |||
| Focal anastomosis abnormality with distal run-off abnormality (n = 9) | 5 (55.6) | 4 (44.4) | |
| Focal anastomosis abnormality without distal run-off abnormality (n = 11) | 1 (9.1) | 10 (90.9) | |
| Diffuse stenosis with recipient hepatic artery stenosis (n = 13) | |||
| Diffuse stenosis with distal run-off abnormality (n = 5) | 5 (100) | 0 (0) | |
| Diffuse stenosis without distal run-off abnormality (n = 8) | 1 (12.5) | 7 (87.5) | |
Data in parentheses are percentages. The majority of false positive occurred when there was anastomosis site abnormality alone, without distal run-off abnormality; therefore, it can be reduced when a combination of both anastomosis site abnormality and distal run-off abnormality is applied as a modified criterion.
