Extraluminal Pelvic Vein Recanalization With Parallel Stents.

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Cardiovascular Medicine

Background:

• Chronic venous stent occlusion can lead to recurrent deep vein thrombosis and significant patient disability.
• Pelvic vein recanalization is challenging, especially with older, occluded stent types.
• Conventional endovascular methods may fail in complex venous obstruction cases.

Purpose of the Study:

• To describe an unusual extraluminal technique for bypassing a chronically occluded pelvic vein stent.
• To present a case of recurrent deep vein thrombosis treated with advanced endovascular methods.
• To evaluate the potential of novel techniques in managing complex venous stent occlusions.

Main Methods:

• A 55-year-old male with recurrent deep vein thrombosis and an occluded pelvic vein stent underwent an extraluminal parallel stent insertion to create a new channel.
• Pharmacomechanical thrombectomy and stenting were employed for a subsequent recurrence 2.5 years later.
• The case highlights advanced endovascular strategies for challenging venous obstructions.

Main Results:

• The extraluminal technique successfully created a bypass, circumventing the occluded stent segment.
• The patient experienced a subsequent recurrence, managed effectively with pharmacomechanical thrombectomy and stenting.
• The case demonstrates the feasibility of advanced techniques in managing complex venous stent occlusions.

Conclusions:

• Recanalization of chronically occluded venous stents often necessitates advanced endovascular techniques.
• Extraluminal stent insertion presents a viable alternative approach for difficult cases of venous stent occlusion.
• Further data is required to establish the reproducibility and long-term efficacy of this technique.
