[Total laparoscopic retrieval of a cava filter: case series]

Area of Science:

• Vascular Surgery
• Interventional Radiology

Background:

• Anticoagulant therapy is standard for venous thromboembolic complications.
• Cava filter placement is indicated when anticoagulation is contraindicated, ineffective, or causes complications.
• Retrieval of vena cava filters carries risks of complications.

Purpose of the Study:

• To evaluate the safety and efficacy of total laparoscopic retrieval of vena cava filters after failed endovascular attempts.
• To present a case series of patients managed with this technique.

Main Methods:

• Analysis of 4 patients treated between February 2015 and March 2017.
• Patients underwent total laparoscopic retrieval of the vena cava filter due to unsuccessful endovascular retrieval.
• Procedure included phlebotomy, filter retrieval, and phlebectomy zone suturing.

Main Results:

• Laparoscopic retrieval was successful in all 4 patients.
• Procedure time ranged from 32 to 45 minutes.
• Maximum blood loss was 300 ml, without need for transfusion.
• No conversion to laparotomy was required.
• No significant systemic or wound complications were observed postoperatively.

Conclusions:

• Total laparoscopic retrieval is a relatively safe and minimally invasive option for vena cava filters when endovascular retrieval fails.
• This method is suitable for experienced surgical teams skilled in laparoscopic and angiosurgical procedures.
