Aortic Banding to Treat Simultaneously a Type Ia Endoleak and Aortic Neck Rupture during Endovascular Abdominal Aortic Aneurysm Repair

Background: Type Ia endoleak due to inadequate seal at the proximal end of the endograft is not infrequent during the initial operation. However, repeated attempts at balloon inflation or over-dilatation of the balloon can produce high axial pressures and can lead to aortic neck rupture with hemodynamic instability. Methods: The purpose of the paper is to present a useful technique for simultaneously treating a type Ia endoleak and aortic neck rupture during endovascular abdominal aortic aneurysm repair. Results: The technique for treating a type Ia endoleak has been described, but it was used for the first time to treat simultaneously a type Ia endoleak and rupture of the aortic neck with active bleeding during endovascular abdominal aortic aneurysm repair. After laparotomy, the left renal vein was ligated and a proximal control was achieved with placement of a vascular clamp above the renal arteries. Effective external banding of the infrarenal neck was performed with two 10-mm polyester Dacron limbs tied in the same fashion, close to one another, and parallel just below the renal arteries. We describe the steps of the surgical technique in detail and we analyze crucial issues associated with the technique. Conclusions: In this paper, we presented a useful technique for simultaneously treating a type Ia endoleak and aortic neck rupture during endovascular abdominal aortic aneurysm repair. Effective external banding of the infrarenal neck led to control of the hemorrhage and exclusion of the blood flow in the aneurysm sac. © 2019 Elsevier Inc

A Technical Tip of Aortic Stump Reinforcement with Plication of the Falciform Ligament of the Liver

Background: The residual stump after excision of an infected aortic graft may be subject to acute disruption—blowout—because of recurrence of infection or fatigue due to the mechanical stress. We present an innovative technique in which we used the falciform ligament of the liver to reinforce the aortic stump. Methods: We excised the falciform ligament by giving attention to avoid any bleeding from the liver. The aortic stump was reinforced with synthetic, monofilament, nonabsorbable polypropylene sutures and the falciform ligament of the liver was plicated inside the stump and further sutured with polypropylene sutures. Results: After 5 months, he is in excellent condition. His laboratory examination is normal, he has stopped taking antibiotics, gained his initial weight, and recovered full activity. Conclusions: We presented an innovative technique in which we used the falciform ligament of the liver to reinforce the aortic stump after excision of an infected aortobiiliac synthetic graft. This technique can be an alternative option in patients with weak arterial wall or extended bacterial local infection in the retroperitoneal area which renders the aortic wall tissue extremely stiff to be folded and sutured. This technique may enhance the mechanical integrity of the stump. © 2020 Elsevier Inc
