Observational studies evaluating inferior vena cava filters (IVCF) in bariatric surgery.
| Reference . | Study type . | Bariatric patient groups . | Outcome . |
|---|---|---|---|
| PE indicates pulmonary embolism; DVT, deep vein thrombosis; UFH, unfractionated heparin. | |||
| Frezza 200620 | Retrospective case-control | High risk + IVCF, n = 9 High risk + intraop UFH, n = 15 | No PE or DVT |
| Gargiulo 200611 | Retrospective review and prospective case-control | 1. High risk, not including BMI, n = 8 2. BMI >55 kg/m2 added to criteria for IVCF, n = 33 | Decreased PE (13% vs 0%) and fatal PE (10% vs 0%) favoring IVCF |
| Halmi 200721 | Prospective case series | High risk, n = 27 | No DVT or PE |
| Kardys 200816 | Retrospective case series | High risk, n = 31 | DVT 1/31, PE 2/31 |
| Keeling 200513 | Retrospective case series | High risk, n = 14 | No PE |
| Obeid 200719 | Retrospective case-control | 1. High risk + IVCF, n = 248 2. Low risk, no IVCF, n = 1851 | No difference in PE (0.81% vs 0.59%), DVT (1.21% vs 0.65%), or death (0.81% vs 0.22%) |
| Overby 2008 | Retrospective case-control | 1. High risk + IVCF, n = 160 2. Low risk, no IVCF, n = 170 | No difference in PE (3% vs 2%) or DVT (0.6% vs 3%) |
| Piano 200723 | Prospective case series | High risk, n = 60 | 1/60 PE (no pharmacologic prophylaxis) |
| Schuster 200717 | Retrospective case series | High risk, n = 24 | DVT 5/24, PE 1/24 (after IVCF retrieval) |
| Trigilio-Black 200722 | Prospective case series | High-risk, n = 41 | DVT 1/41, no PE |
| Vaziri 2008 | Prospective case series | High risk, n = 30 | DVT 6/30, no PE |
