Abstract
Background: Current guidelines recommend preserving at least one of the bilateral pelvic flows in patients with aortoiliac aneurysms. The sandwich parallel graft, using commercially available devices, provides a viable option for patients who fall outside the instructions for use of iliac branch devices. However, gutter endoleak remains a significant challenge.
Case report: A 78-year-old woman with an incidentally discovered small AAA and bilateral CIAAs experienced aneurysmal growth to 42 mm for the abdominal aortic aneurysm (AAA) and 41 mm and 33 mm for the right and left common iliac artery aneurysms (CIAAs), respectively. Morphologic assessment of the aortoiliac aneurysm revealed the nearly 90-degree angles of the bilateral iliac bifurcations and the tortuous path of the internal iliac arteries. The iliac branch device was considered relatively contraindicated and ineligible; therefore, to preserve pelvic blood flow, the decision was made to employ the sandwich parallel graft technique in the left iliac arteries. Following the placement of the sandwich graft within the iliac limb, standard procedures were carried out. However, completion angiography revealed a type IA endoleak and a significant gutter endoleak in the left CIAA extending to the AAA sac. Despite the extension of overlapping zone, the gutter endoleak persisted after a 10 min waiting period. Therefore, we then advanced an 014 wire and a microcatheter to selectively access the gutter endoleak and performed embolization using multiple detachable coils. The final angiography showed complete resolution of the gutter endoleak and computed tomography angiography 1-month postoperatively confirmed the absence of any endoleaks.
Conclusion: This case report highlights that targeted embolization is a feasible and effective treatment for significant gutter endoleak following the sandwich parallel graft technique.
期刊介绍：
Evidence of surgical interventions go back to prehistoric times. Since then, the field of surgery has developed into a complex array of specialties and procedures, particularly with the advent of microsurgery, lasers and minimally invasive techniques. The advanced skills now required from surgeons has led to ever increasing specialization, though these still share important fundamental principles.
Frontiers in Surgery is the umbrella journal representing the publication interests of all surgical specialties. It is divided into several “Specialty Sections” listed below. All these sections have their own Specialty Chief Editor, Editorial Board and homepage, but all articles carry the citation Frontiers in Surgery.
Frontiers in Surgery calls upon medical professionals and scientists from all surgical specialties to publish their experimental and clinical studies in this journal. By assembling all surgical specialties, which nonetheless retain their independence, under the common umbrella of Frontiers in Surgery, a powerful publication venue is created. Since there is often overlap and common ground between the different surgical specialties, assembly of all surgical disciplines into a single journal will foster a collaborative dialogue amongst the surgical community. This means that publications, which are also of interest to other surgical specialties, will reach a wider audience and have greater impact.
The aim of this multidisciplinary journal is to create a discussion and knowledge platform of advances and research findings in surgical practice today to continuously improve clinical management of patients and foster innovation in this field.
