  Introduction Top


Inferior vena cava (IVC) filters form an important part of the armamentarium in vena caval interruption. Their primary role is to prevent pulmonary embolism and not to treat or prevent venous clots.[1]


  Types and Designs of Inferior Vena Cava Filters Top


The earliest design of an IVC filter was a silicon membrane with multiple holes, known as the Mobin-Uddin filter named after the scientist who designed it.[2] The original Greenfield filter with the conical design introduced in 1973 has remained the design standard for successive decades. Today, several designs of IVC filters are also available in the market, including conical designs, double-helical designs, and double-basket type. In addition, filters can be broadly divided into four different types, as shown in [Table 1].

  Indications of Inferior Vena Cava Filters Top


Today, a plethora of devices are available in the market from several manufacturers. Although their primary use was interventional in patients who could not be anticoagulated, there has been an increase in the use of these devices for prophylactic indications. This can be attributed to the growing body of knowledge and skill with endovascular techniques and the safety profile of these devices.[3] However, in every patient, it would be prudent to regard the benefits and harms prior to making the decision of an IVC filter insertion. The host of clinical decision-making pathways can be grouped into three categories – indications backed by evidence, relative expanded indications, and contraindications. These are listed in [Table 2].[1]

  Conclusions Top


Current ACCP guidelines recommend against the use of IVC filters in any patient who can receive therapeutic anticoagulation.[4] While the mortality benefit of IVC filters is debatable at best, their role in the prevention of pulmonary embolism has been established.[1] The indications and use of vena caval filters are still on the rise. With novel devices such as Angel Catheter currently entering the market, new avenues are opening up for the prophylactic use of filters in critically ill patients.[5]
