AbstractWe report a case of aortic pseudoaneurysm associated with a fractured bare Cheatham-Platinum stent following stenting for aortic coarctation. These complications were recognised 6 years after the implantation procedure and were successfully managed by percutaneous stent graft implantation. Staged approach for stent dilatation might prevent development of aortic pseudoaneurysms. In addition, careful follow-up is warranted after stenting for aortic coarctation, particularly in patients with recognised aortic wall injury.

Purpose: To outline the complications encountered after endoluminal treatment in patients with type B aortic dissection. Methods: Between 1999 and 2001, 14 patients (12 men; mean age 60.3 years, range 39–79) with isolated type B aortic dissection (13 chronic, 1 acute) underwent aortic stent-grafting. Three patients with chronic dissection presented an acute clinical picture and were managed emergently. The left subclavian artery was intentionally covered by the prosthesis in 9 patients. Follow-up studies were performed at 6-month intervals. Results: Stent-graft implantation was technically successful in all patients, but incomplete sealing (endoleak) of the entry site required additional proximal stent-graft implantation in 4. The left subclavian artery remained patent in 5 patients. Secondary conversion was required in 3 patients: 2 for acute type A dissection resulting from injury to the aortic arch by Talent endografts and a sustained hemorrhage (left hemothorax). In another patient, a secondary intramural hematoma subsided spontaneously. Anterior spinal artery syndrome in 1 patient persisted at 1 month. No bypass was necessary for the 9 patients with the covered left subclavian arteries. Mean follow-up was 14 months (range 1–23). Conclusions: Stent-grafting is feasible in patients with type B aortic dissection, although it is associated with a considerable rate of complications. Frank reporting of these sequelae for a variety of stent-grafts is of paramount importance to clarifying the limitations of the method.

Purpose: To report the use of the Nellix endovascular aneurysm sealing (EVAS) system in the management of proximal stent-graft collapse associated with thrombosis following endovascular aneurysm repair (EVAR). Case Report: A 76-year-old man was admitted for proximal collapse of an aortic extension following bifurcated AFX stent-graft implantation associated with chimney grafts in both renal arteries and the superior mesenteric artery 1 month prior. Imaging identified thrombosis of the aortic stent-graft and the iliac limbs. A Nellix EVAS was placed into the AFX stent-graft to recanalize the aneurysm lumen and address the aortic thrombosis. There was no endoleak, and the renovisceral chimney stent-grafts remained patent over a follow-up of 25 months. Conclusion: While further studies are required to generalize its use, EVAS appears to be feasible in the management of aortic stent-graft collapse.

Endovascular treatment of a giant extracranial internal carotid aneurysm by a stent graft implantation was unsuccessful due to a high flow leak directly through the stent graft’s coating. The problem was solved deploying a second stent graft inside the previously implanted one resulting in complete exclusion of the aneurysmal sac and patent carotid lumen preservation. The review of the literature did not provide a case using this endovascular strategy. Follow-up for more than 12 months, using CT angiography, showed confirmed aneurysmal exclusion and carotid patency and no clinical complications have been detected.

Purpose: To evaluate the early and midterm outcomes after stent-graft implantation for dissection in the descending thoracic aorta. Methods: Sixteen custom-made endovascular stent-grafts were implanted in 15 patients (10 men; mean age 55.9 ± 13.7 years, range 32–82) with descending thoracic aortic dissection. Indications for stent-graft implantation were persistent symptoms unresponsive to medical treatment or progressive enlargement of the false lumen. Clinical and imaging surveillance with computed tomography was performed within 1 month of the procedure and at 3 to 6-month intervals in follow-up. Results: Endovascular stent-graft implantation at the target site was successful in 14 (93%) patients; 1 device migrated, leaving the false lumen open to flow in the failed case. One (7%) patient who was treated emergently for rupture died suddenly 2 days after the procedure. Over an average follow-up of 31.5 ± 23.8 months, 1 (7%) patient died and 2 (14%) patients underwent surgical treatment due to recurrent dissection. The remaining 10 patients showed complete thrombosis of the false lumen; in 3, the false lumen completely resolved. Conclusions: Endovascular stent-graft implantation in descending thoracic aortic dissection is a feasible, safe, and effective treatment modality. However, further studies are necessary in a greater number of patients to determine if wider application of this minimally invasive procedure is justified.

Endovascular stent graft implantation is a favorable method for complex aortic coarctation accompanied by patent ductus arteriosus. Herein, an 18-year-old woman with complex aortic coarctation and patent ductus arteriosus was successfully treated by endovascular thoracic stent graft via retroperitoneal approach. The reason for retroperitoneal iliac approach was small sized common femoral arteries which were not suitable for stent graft passage. This case is the first aortic coarctation plus patent ductus arteriosus case described in the literature which is treated by endovascular thoracic stent graft via retroperitoneal approach.

Abstract Purpose To investigate efficacy and patency status of stent graft implantation in the treatment of hepatic artery pseudoaneurysm. Materials and Methods A retrospective analysis of patients who had undergone endovascular treatment of hepatic artery pseudoaneurysms between 2011 and 2020 was performed. Medical records were examined to obtain patients’ surgical histories and to screen for active bleeding. Angiographic data on vascular access, target vessel, material used and technical success, defined as the exclusion of the pseudoaneurysm by means of a stent graft with sufficient control of bleeding, were collected. Vessel patency at follow-up CT was analyzed and classified as short-term (< 6 weeks), mid-term (between 6 weeks and 1 year), and long-term patency (> 1 year). In case of stent occlusion, collateralization and signs of hepatic hypoperfusion were examined. Results In total, 30 patients were included and of these, 25 and 5 had undergone stent graft implantation and coiling, respectively. In patients with implanted stent grafts, technical success was achieved in 23/25 patients (92%). Follow-up CT scans were available in 16 patients, showing stent graft patency in 9/16 patients (56%). Short-term, mid-term, and long-term short-term stent patency was found in 81% (13/16), 40% (4/10), and 50% (2/4). In patients with stent graft occlusion, 86% (6/7) exhibited maintenance of arterial liver perfusion via collaterals and 14% (1/7) exhibited liver abscess during follow-up. Conclusion Stent graft provides an effective treatment for hepatic artery pseudoaneurysms. Even though patency rates decreased as a function of time, stent occlusion was mainly asymptomatic due to sufficient collateralization.

Purpose: To examine aortic histology 1 year after stent-graft implantation in a canine model as a means of assessing the durability of endograft fixation. Methods: Fourteen mongrel dogs each received 1 stent-graft and 1 bare stent placed endoluminally in the abdominal aorta. Eight animals were followed for 1 year, 3 for 4 to 8 weeks, and the remaining 3 for 24 to 48 hours. Aortic specimens were stained with hematoxylin-eosin, elastica-van Gieson, and Masson's trichrome and examined with light and electron microscopy and immunohistochemistry to identify smooth muscle cells (SMC), endothelialization, aortic wall ultrastructure, and changes at the device anchoring sites. Results: No dilatation or dissection was noted at any of the device anchoring sites. The aortic media at 1 year was remarkably decreased in thickness: 891 ± 196 µm in the control tissue versus 388 ± 70 µm for the proximal stent-grafted aorta and 457 ± 148 µm for the bare-stented aortic segment. Other important histological features were reduced elastic lamellae in the stent-grafted aorta versus control (p<0.0001), increased SMC density in the stent-grafted aortic region (p<0.0001 versus control), and absence of inflammatory infiltrate. Complete neointimal covering and endothelialization of the luminal endograft surface were found. SMCs generally showed no ultrastructural features of necrosis. Conclusions: Aortic stent-grafts induce distinctive histological changes in the aortic wall at 1 year, even when implanted in a healthy aorta. Although there is considerable medial elastin loss, an increased medial SMC density, an exuberant neointima, and a general absence of perigraft inflammation suggest an ongoing process of structural restoration at the device anchoring sites.
