Abstract

This article introduces the Lobato technique for complicated isolated iliac dissection (SID-IA). By modifying stent deployment in a 2mm true lumen, this approach achieved revascularization without endoleak, demonstrating feasibility in IBD-contraindicated or emergency cases.

Introduction

SID-IA management lacks consensus. The Lobato technique addresses anatomical constraints (true lumen ≥2mm), expanding endovascular options.

Case Study

A SID-IA patient with true lumen compression (2mm):

Access: Retrograde femoral approach with short sheaths.

Stent Deployment: Multilayer covered stents tailored for small lumina.

Outcome: True lumen expanded to 8mm postoperatively.

No complications at 30-day follow-up.

Conclusions

1.The Lobato technique bypasses IBD limitations.

2.Streamlined steps enhance emergency applicability.

3.Long-term surveillance is critical for durability.
