Purpose: To develop laparoscopic techniques for aortic stent-graft placement as an alternative to the femoral approach. Methods: Endovascular stent-grafts were placed in 8 pigs via a totally laparoscopic retroperitoneal approach. After needle puncture, a guidewire was inserted into the abdominal aorta, followed by an 18-F sheath through which a Talent stent-graft was deployed in the descending thoracic aorta without aortic clamping. All the endovascular tools were inserted into the retroperitoneal area via the ports. After the sheath was withdrawn, hemostasis was achieved by suturing the aortic puncture under aortic cross-clamping. After sacrificing the animals, the thoracic aorta was removed to verify the position and deployment of the stent-grafts. Results: Seven (87.5%) of 8 procedures were successfully completed; the first animal died from hemorrhage due to inadvertent injury to the posterior infrarenal aortic wall. The accurate deployment and position of the stent-grafts were verified visually after sacrifice. Mean (± SD) procedural, implantation, and aortic cross-clamping times were 205 ± 56, 22 ± 9, and 30 ± 19 minutes, respectively. Mean blood loss was 120 ± 56 mL. Conclusions: Thoracic aortic stent-grafting using a laparoscopic approach to the infrarenal aorta is feasible. More studies will be required to define the place of combined endovascular and laparoscopic procedures as an alternative to the femoral surgical approach for stent-graft placement.

Abstract Background Surgical management of patients with abdominal aortic diseases associated with distal narrowing is a challenging situation. Objectives To evaluate outcomes of unibody bifurcated endovascular stent graft repair. Methods This is a retrospective, observational, multi-institutional database study of a cohort of consecutive cases, approved by the local Ethics Committee. Records were reviewed of patients diagnosed from 2010 to 2020 with “shaggy” aorta, saccular aneurysm, penetrating aortic ulcer, and isolated aortic dissection located in the infrarenal abdominal aorta. All patients were treated with a unibody bifurcated stent graft. Main outcomes were technical success, procedure complications, long-term patency, and mortality in the follow-up period up to 5 years. Data on demographics, comorbidities, surgical management, and outcomes were analyzed. Results Twenty-three patients were treated with unibody bifurcated stent graft repair, including 7 cases of “shaggy” aorta, 3 isolated dissections of the abdominal aorta, 4 penetrating aortic ulcers, and 9 saccular aneurysms. Immediate technical success was achieved in 100% of cases. At follow-up, all stent grafts remained patent and there were no limb occlusions. The patients were symptom-free and reported no complications related to the procedure. There were 5 deaths during the follow-up period (median= 4 years), but none were related to the procedure and there were no aorta-related deaths. Conclusions The present study shows that unibody bifurcated stent grafting is safe and effective in this group of patients with narrow distal abdominal aorta and complex aortic pathology. The results were similar for both infrarenal aortic aneurysms and aorto-iliac atherosclerotic disease.

Stent Grafting

Background: Primary infection of the abdominal aorta is a rare pathology that may threaten the integrity of the aortic wall, while secondary aortic prosthesis infection represents a devastating complication to open surgical and endovascular aortic surgery. Curative treatment is achievable by removal of all infected prosthetic material followed by a vascular reconstruction. Design and Methods: Twelve consecutive patients treated with the neo-aortoiliac system bypass (NAIS) procedure were reviewed. Nine were treated for a secondary aortic prosthesis infection (tube graft n = 3, bifurcated graft n = 4, endovascular aortic repair (EVAR) stent graft n = 1, and fenestrated EVAR [FEVAR] stent graft n = 1), while 3 patients underwent NAIS repair due to an emergent primary mycotic aortoiliac aneurysm. Primary Results: Ten of 12 patients survived 30 days. Three patients were operated on acutely, and 9 patients had elective or subacute NAIS surgery. Two of 3 patients operated acutely died within 30 days, whereas no 30-day or 1-year mortality was observed in patients undergoing elective or subacute surgery. The median time from primary reconstruction to the NAIS procedure was 11 months (range: 0-201 months). Stent grafts (n = 5 of 12) were in 4 cases explanted using endovascular balloon clamping. Of the explanted endografts, 2 patients presented with a secondary graft infection after EVAR/FEVAR, while 3 patients had been emergently treated with endovascular cuffs as a “bridge-to-surgery” procedure due to aortoenteric fistula (AEF). Patients who received a “bridge-to-surgery” regimen were treated with the NAIS procedure within 8 weeks (median 27 days, range: 27-60) after receiving emergency stent grafting. Principal Conclusions: Aortic balloon-clamping during explantation of infected aortic prosthetic endografts is feasible and facilitates complete endograft removal. Endovascular bridging procedures could be beneficiary in the treatment of AEF or anastomotic dehiscence due to graft infection, offering a possibility to convert the acute setting to an elective definitive reconstructive procedure with a higher overall success rate.
