AngioVac suction embolectomy using a roller pump: Operative technique

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Interventional Cardiology

Background:

• The AngioVac system is designed for suction embolectomy, with manufacturer recommendations favoring centrifugal pumps for safety.
• Roller head pumps present a more economical and accessible alternative, particularly in resource-limited or shortage situations.

Purpose of the Study:

• To demonstrate the feasibility and safety of using a roller pump for AngioVac suction embolectomy.
• To present a case of successful clot-in-transit removal from the inferior vena cava and right atrium using this technique.

Main Methods:

• Successful application of the AngioVac system with a roller pump for suction embolectomy.
• Evacuation of a clot-in-transit located in the inferior vena cava and right atrium.

Main Results:

• The procedure successfully removed the clot-in-transit.
• The use of a roller pump proved to be a viable alternative to centrifugal pumps in this case.

Conclusions:

• AngioVac suction embolectomy can be effectively performed using a roller pump.
• This approach offers a potentially more accessible and cost-effective option for clot retrieval, with careful consideration of safety caveats.
