Recanalization, reintervention, and complication rates by vein diameter compared with χ2 tests
| >1.0 cm (n = 33) | ≤ 1.0 cm (n = 153) | P value | |
|---|---|---|---|
| Recanalization within 2 years | 5 (15.2) | 13 (8.5) | .326 |
| Reintervention within 2 years | 2 (6.1) | 3 (2.0) | .206 |
| Complications | |||
| Any complication | 8 (24.2) | 11 (7.2) | .011 |
| Ablation-associated thrombosis | 3 (9.1) | 2 (1.3) | – |
| Pain | 4 (12.1) | 4 (2.6) | – |
| Hematoma | 2 (6.1) | 4 (2.6) | – |
| Hyperpigmentation | 0 (0.0) | 3 (2.0) | – |
Values are number (%).
Patients in the large vein cohort were more likely to develop a complication (P < .05). Rates of ablation-associated thrombosis, postoperative pain, and hematoma were higher in the large vein cohort. Two patients in the small vein cohort developed postoperative hyperpigmentation. The χ2 tests are unreliable with such small patient numbers (<5 affected patients per complication per group) and are therefore omitted. There were no instances of postoperative burning sensation, paresthesias, saphenous neuralgia, puncture site complications, or induration in either group.
