Non-Retrievable Vena Cava Filters

**Non-Retrievable Vena Cava Filters: Medical Device Overview**

Non-retrievable vena cava filters (NRVCFs) are medical devices surgically placed in the inferior vena cava to prevent blood clots from reaching the lungs. They are employed when anticoagulants are ineffective or contraindicated. This article provides a comprehensive overview of NRVCFs, covering:

**Indications:**
* Deep Vein Thrombosis (DVT)
* Pulmonary Embolism (PE)

**Materials:**
* Nitinol or stainless steel
* Permanent or temporary options

**Mechanism:**
* Traps blood clots before they travel to the lungs
* Reduces risk of PE

**Insertion Techniques:**
* Jugular vein access
* Femoral vein access

**Advantages:**
* Effective clot prevention
* Reduced risk of PE

**Disadvantages:**
* Can cause IVC occlusion or perforation
* May increase risk of DVT below the filter

**Post-Insertion Management:**
* Monitor for complications
* Regular ultrasound follow-ups to assess filter position and patency
