“…Unfixed ePTFE allows the fabric to expand along the aortic wall, allowing no need for a strong radial force for sealing. 6,7 Furthermore, this characteristic also enables limited contact of the bare stent to the intima. Minimal radial force and endoskeleton characteristics of Najuta was useful in securing the landing zone for multiple endograft while reducing the risk for SINE by reducing the stress to the native aortic wall.…”

A 67-year-old woman with a prior history of aortic dissection was admitted for enlarging the thoracoabdominal aortic aneurysm (TAAA). She has received multiple treatments including Bentall procedure, hemiarch replacement, and subsequent endovascular procedures for the closure of re-entry. Preoperative computed tomography revealed previously implanted thoracic endograft from distal arch to superior mesenteric artery with dissected TAAA measuring up to 70 mm in diameter. Re-entry was observed at bilateral common iliac arteries. The patient was successfully treated by endovascular treatment using a fenestrated stent graft to obtain a landing zone for parallel endograft technique to the iliac arteries for the closure of re-entry.

“…These fenestrations are crossed by stent-struts and are not reinforced, so that no additional stenting of these fenestrations is possible. Iwakoshi et al reported technical success rate of 91% using the Najuta stent-graft in 32 patients (27). Aneurysm-related rate and rate of freedom from secondary intervention at 3 years were 97% and 84%, respectively (27).…”

During the last 20 years, a clear shift has been observed towards thoracic endovascular aortic repair for different aortic pathologies. However, total endovascular repair of the aortic arch remains technically demanding. Simultaneous perfusion of all supra-aortic arteries without longer cerebral ischemia time, whilst trying to avoid cerebral embolization, labels endovascular aortic arch repair with highest level of technical difficulty and surgical expertise. The aim of this article is to present an overview of the current technical options for endovascular aortic arch repair and their early results. Currently, early results are reported from four endovascular arch replacement techniques: hybrid repair, total endovascular approach, chimney grafts and in-situ fenestration. The early results of these different arch replacement techniques are promising, especially the total arch replacement with custom-made fenestrated or branched stent-grafts. Long-term results are unknown, and larger series results and comparative studies are needed to determine safety and efficacy.

“…However, the reintervention rate was relatively high at 10%. 34,35 The devices of both a-Branch and Bolton dual-branch aortic arch endografts have two inner sleeves for reconstructing the BCA and LCCA. The preliminary results of 26 patients undergoing branched TEVAR with Bolton dual-branch graft revealed a 30-day mortality of 7.7% and postoperative stroke in 3.8% of cases.…”

Endovascular Treatment of Various Aortic Pathologies: Review of the Latest Data and Technologies

The technologies and innovations applicable to endovascular treatment for complex aortic pathologies have progressed rapidly over the last two decades. Although the initial outcomes of an endovascular aortic repair have been excellent, as long-term data became available, complications including endoleaks, endograft migration, and endograft infection have become apparent and are of concern. Previously, the indication for endovascular therapy was restricted to descending thoracic aortic aneurysms and abdominal aortic aneurysms. However, its indication has expanded along with the improvement of techniques and devices, and currently, it has become possible to treat pararenal aortic aneurysms and Crawford type 4 thoracoabdominal aortic aneurysm (TAAA) using the off-the-shelf devices. Additionally, custom-made devices allow for the treatment of arch or more extensive TAAAs. Endovascular treatment is applied not only to aneurysms but also to acute/chronic dissections. However, long-term outcomes are still unclear. This article provides an overview of available devices and the results of endovascular treatment for various aortic pathologies.

Clinical outcomes of thoracic endovascular aneurysm repair using commercially available fenestrated stent graft (Najuta endograft)

Abstract: The perioperative and 3-year outcomes of TEVAR using the Najuta precurved, fenestrated endograft demonstrated high freedom from aneurysm enlargement and patency rates of the supra-aortic branches.
