“…In addition to the risk of rupture, IAAs are prone to thrombus formation and embolism, further increasing the mortality risk[ 11 ]. The risk factors for IAAs mirror those for atherosclerotic diseases and include hypertension, smoking, and hyperlipidemia[ 12 , 13 ]. If left untreated, IAAs are likely to rupture, which can lead to life-threatening hemorrhage or, in rare instances, adjacent organ invasion[ 14 , 15 ], as noted in the current case involving rectal bleeding.…”

BACKGROUND This case report presents the rare occurrence of hematochezia due to an internal iliac artery aneurysm leading to an arterioenteric fistula, expanding the differential diagnosis for gastrointestinal bleeding. It emphasizes the importance of considering vascular origins in cases of atypical hematochezia, particularly in the absence of common gastrointestinal causes, and highlights the role of imaging and multidisciplinary management in diagnosing and treating such unusual presentations. CASE SUMMARY A 75-year-old man with a history of hypertension presented with 12 d of hematochezia, experiencing bloody stools 7-8 times per day. Initial computed tomography (CT) scans revealed an aneurysmal rupture near the right internal iliac artery with suspected hematoma development. Hemoglobin levels progressively decreased to 7 g/dL. Emergency arterial angiography and iliac artery-covered stent placement were performed, followed by balloon angioplasty. Despite initial stabilization, minor rectal bleeding and abdominal pain persisted, leading to further diagnostic colonoscopy. This identified a neoplasm and potential perforation at the proximal rectum. An exploratory laparotomy confirmed the presence of a hematoma and an aneurysm invading the rectal wall, necessitating partial rectal resection, intestinal anastomosis, and ileostomy. Postoperative recovery was successful, with no further bleeding incidents and normal follow-up CT and colonoscopy results after six months. CONCLUSION In cases of unusual gastrointestinal bleeding, it is necessary to consider vascular causes for effective diagnosis and intervention.

“…The bifurcation part of the unibody bifurcated stent-graft is located at the bifurcation of the abdominal aorta, forming a "two-point" fixation with the proximal end of the stent and tumor neck anchor, which enjoys long-term stability after implantation. 7,8 Placement of the guide wire on the opposite side of the unibody bifurcated stent-graft in advance can shorten the operation time and simplify the surgical procedure. 9,10 In view of the above-described advantages of the unibody bifurcated stent-graft, this endovascular repair has received increasing attention.…”

Internal iliac coverage during endovascular repair of abdominal aortic aneurysms is a safe option: A preliminary study

et al. 2016

Endovascular aneurysm repairs lacking suitable common iliac artery landing zones occasionally require graft limb extension into the external iliac artery, covering the internal iliac artery origin. The purpose of this study was to assess incidence of type II endoleak following simple coverage of internal iliac artery without embolization during endovascular aneurysm repair. Three hundred eighty-nine endovascular aneurysm repairs performed by a single surgeon (2004-2015) were reviewed. Twenty-seven patients underwent simple internal iliac artery coverage. Type II endoleak was assessed from operative reports and follow-up computed tomography imaging. No patient suffered type II endoleak from a covered internal iliac artery in post-operative computed tomography scans. Follow-up ranged from 0.5 to 9 years. No severe pelvic ischemic complications were observed. In conclusion, for selected cases internal iliac artery coverage without embolization is a safe alternative to embolization in endovascular aneurysm repairs, where the graft must be extended into the external iliac artery.
