Surfacer Inside-Out Central Venous Catheterization Through an Occluded Inferior Vena Cava

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Technology

Background:

• Inferior vena cava (IVC) occlusions present significant challenges for venous access.
• Traditional access methods carry risks, especially in cases of acute thrombosis.
• The Surfacer® Inside-Out Access Catheter System (SIO) is designed for complex venous access.

Observation:

• A patient with a chronic IVC occlusion, previously contraindicated for standard procedures, was considered for the SIO system.
• Imaging confirmed the chronic nature of the occlusion, mitigating acute embolization risks.
• The SIO procedure was successfully employed using an indwelling catheter for venous access.

Findings:

• The SIO system provided a viable solution for achieving venous access in a complex chronic IVC occlusion.
• This approach enabled intervention in a patient who had exhausted other treatment options.
• Successful catheter placement was achieved despite the challenging anatomical obstruction.

Implications:

• The SIO procedure may expand treatment possibilities for patients with complex central venous occlusions.
• This case suggests careful patient selection can allow for SIO use in specific chronic occlusion scenarios.
• Further research into SIO system efficacy in diverse venous occlusion etiologies is warranted.
