Abstract
The iliac branch device (IBD) has emerged as the optimal method for endovascular reconstruction of internal iliac artery (IIA). However, due to its high anatomical requirements, the applicability rate among East Asians is limited, especially for common iliac artery aneurysm (CIAA) with narrow inner lumen cases. Here, we report a case with narrow distal inner lumen of the CIAA treated with a novel surgeon-modified inner branch iliac branch device (IIBD). This is a case report, and consent for publication was obtained from the patient. The 1-year follow-up CTA showed that the CIAA regressed without abdominal pain. Right CIA, external iliac artery, and IIA were all patent. The IIBD technique has lower anatomical requirements for the CIA. Therefore, it may be a feasible option for IIA preservation in cases of CIAA with narrow inner lumen.
