Summary
The Mobin-Uddin vena cava filter is a safe and effective method for vena cava interruption in high-risk patients. This study shows low operative morbidity and 30-day mortality, with no recurrent pulmonary embolism cases observed.
Area of Science:
- Vascular Surgery
- Medical Devices
- Interventional Radiology
Background:
- The Mobin-Uddin vena cava filter has been utilized since 1971.
- Vena cava filters are crucial for preventing pulmonary embolism in high-risk patients.
Purpose of the Study:
- To evaluate the safety and efficacy of the Mobin-Uddin vena cava umbrella filter.
- To assess operative morbidity, mortality, and late sequelae in patients receiving the filter.
Main Methods:
- Retrospective analysis of 128 high-risk patients who received the Mobin-Uddin filter.
- Data collection on patient demographics, filter placement, operative complications, and long-term outcomes.
Main Results:
- 128 high-risk patients (mean age 60, 42% with malignancies) received the filter.
- Operative morbidity was 6.2% (wound hematomas, misplaced filter, retroperitoneal hematoma, vena cava occlusion).
- 30-day mortality was 7.0%; no deaths directly attributed to filter placement. Late sequelae included mild (6%) and severe (16%) edema. No recurrent pulmonary embolism was noted.
Conclusions:
- The Mobin-Uddin vena cava umbrella filter is a safe and effective intervention for vena cava interruption.
- The filter demonstrates low operative morbidity and 30-day mortality in a high-risk patient cohort.
- Absence of recurrent pulmonary embolism suggests efficacy in preventing major thromboembolic events.
