Abstract
Thoracic endovascular aneurysm repair has been well described in the literature as a treatment for a wide range of thoracic aortic pathologies. As with any intervention, there remains a risk of an unfavorable outcome, including endoleak, a term used to describe unexpected blood flow between the stent-graft and the wall of the excluded aneurysm. Endoleaks cause pressurized enlargement of the aneurysmal sac and may lead to catastrophic outcomes such as rupture and death. Type 1b endoleak represents a distal landing zone that is compromised by retrograde blood flow. Moreover, there is a lack of data on type 1b endoleaks and its management options. With the increase in emerging endovascular techniques and technologies, endoleaks are more frequent. However, the management of endoleaks is not standardized among different centers. The purpose of this article is to provide an overview of type 1b endoleaks after thoracic endovascular aneurysm repair, current management options, and our experience.

Abstract
Although substantial progress has been made in the prevention, diagnosis, and treatment of acute aortic dissection, it remains a complex cardiovascular event, with a high immediate mortality and substantial morbidity in individuals surviving the acute period. The past decade has allowed a leap forward in understanding the pathophysiology of this disease; the existing classifications have been challenged, and the scientific community moves towards a nomenclature that is likely to unify the current definitions according to morphology and function. The most important pathophysiological pathway, namely the location and extension of the initial intimal tear, which causes a disruption of the media layer of the aortic wall, together with the size of the affected aortic segments, determines whether the patient should undergo emergency surgery, an endovascular intervention, or receive optimal medical treatment. The scientific evidence for the management and follow-up of acute aortic dissection continues to evolve. This Seminar provides a clinically relevant overview of potential prevention, diagnosis, and management of acute aortic dissection, which is the most severe acute aortic syndrome.

Abstract
Aortic dissection is a chronic disease that requires lifelong clinical and imaging surveillance, long after the acute event. Imaging has an important role in prognosis, timing of repair, device sizing, and monitoring for complications, especially in the endovascular therapy era. Important anatomic features at preprocedural imaging include the location of the primary intimal tear and aortic zonal and branch vessel involvement, which influence the treatment strategy. Challenges of repair in the chronic phase include a small true lumen in conjunction with a stiff intimal flap, complex anatomy, and retrograde perfusion from distal reentry tears. The role of thoracic endovascular aortic repair (TEVAR) remains controversial for treatment of chronic aortic dissection. Standard TEVAR is aimed at excluding the primary intimal tear to decrease false lumen perfusion, induce false lumen thrombosis, promote aortic remodeling, and prevent aortic growth. In addition to covering the primary intimal tear with an endograft, several adjunctive techniques have been developed to mitigate retrograde false lumen perfusion. These techniques are broadly categorized into false lumen obliteration and landing zone optimization strategies, such as the provisional extension to induce complete attachment (PETTICOAT), false lumen embolization, cheese-wire fenestration, and knickerbocker techniques. Familiarity with these techniques is important to recognize expected changes and complications at postintervention imaging. The authors detail imaging options, provide examples of simple and complex endovascular repairs of aortic dissections, and highlight complications that can be associated with various techniques. Online supplemental material is available for this article. ©RSNA, 2022.

Abstract
OBJECTIVE Endovascular repair of post-type-A aortic dissection after open ascending replacement (PTAD) has recently been shown as safe and feasible, but with limited anatomic applicability since only one stent graft was evaluated. We assessed anatomic and clinical applicability of six commercially available branched/fenestrated stent grafts for endovascular repair of PTAD. METHODS On postoperative CT-scans of 101 patients, we measured aortic diameter at: sino-tubular junction, supra-aortic vessels (SAV), and descending aorta, as well as the distances between these landmarks along the outer curvature of the arch and the diameters of the SAV. Anatomical applicability was evaluated according to the instructions-for-use, clinical applicability with regard to supra-aortic and iliac arteries. Assessed devices were: Cook aortic double branch; Terumo double branch; Najuta fenestrated; Endospan Nexus; Medtronic Mona LSA; and Gore TAG thoracic branch. RESULTS Single devices were anatomically and clinically applicable between 19/101 (Mona LSA) and 83/101 (Najuta) cases. Reasons for rejection varied considerably across devices. With all devices available, anatomical applicability was 97/101 and clinical applicability 95/101. Combinations of a fenestrated and a branched device showed the most favorable clinical applicability for a pair of two devices, ranging from 86/101 to 94/101. CONCLUSIONS Anatomical and clinical applicability of endovascular devices for the repair of PTAD is high for fenestrated and branched devices, and very high for the combination of fenestrated and branched devices. Manufacturers should amend specific device requirements for PTAD. Surgeons should emphasize the need for a sufficiently long and straight graft as a potential landing zone.

Abstract
Background Persistent false lumen patency in chronic thoracoabdominal aortic dissections after thoracic endovascular aortic repair (TEVAR) contributes to negative aortic remodeling. We have previously described the evolution of various endovascular techniques to treat persistent false lumen perfusion including false lumen embolization. Objectives of this study are to describe endovascular techniques to obliterate the false lumen and present updated outcomes in a recent series of patients undergoing false lumen embolization for chronic aortic dissection. Methods From January 2018 to May 2021, 17 patients with chronic dissection underwent false lumen embolization with coils, iliac plugs, and nitinol plugs. This was often in conjunction with or following TEVAR and balloon fracture fenestration. Mean follow-up 354±324 days. Results After false lumen embolization there was no mortality, stroke, spinal cord ischemia, or visceral and limb ischemia. No patients required dialysis, though 1 (5.9%) did experience acute kidney injury. There was 1 (5.9%) patient that required endovascular re-intervention on the thoracoabdominal aorta. No patients underwent subsequent open surgical repair. Conclusions TEVAR with adjunctive false lumen embolization and balloon fracture fenestration are techniques to obliterate retrograde flow into the false lumen of chronic thoracoabdominal aortic dissections in appropriately selected patients.

Abstract
BACKGROUND This study was aimed to evaluate the outcomes of performing open repair or thoracic endovascular aortic repair for chronic type B dissecting aortic aneurysm. METHODS From July 2004 to February 2019, 52 patients underwent surgery as open repair (n = 32) or endovascular repair (n = 20) for chronic type B dissecting aortic aneurysm. Replacement of the aorta was limited to the aneurysmal portion with or without reconstructing the visceral arteries or the segmental arteries. Stent grafts were deployed in the true lumen above the celiac artery to cover the primary entry for even DeBakey IIIb dissection. RESULTS Operative mortality and morbidity rates, including spinal cord ischemia incidence, did not differ between the groups. Operative mortality and morbidity rates, including spinal cord ischemia incidence, did not differ between the groups. In the endovascular repair group, 3 patients died due to rupture of residual false lumen in the early, and late postoperative follow-up. The 5-year rate of freedom from all-cause death, aorta-related death, and aorta-related event were 84% ± 6%, 94% ± 3% and 84% ± 6%. The endovascular repair was independently associated with all-cause death (hazard ratio [HR], 5.7; confidence interval [CI], 1.02-31.6; P = 0.04) and aorta-related event (HR, 30.9; CI 4.9-195.0; P < 0.001). In the open group, postoperative residual aortic diameter was an independent predictor of aorta-related events, and the threshold was 41 mm. CONCLUSIONS Open repair remains a better option than simple endovascular repair alone in DeBakey IIIb dissection, but the distal un-resected aortic portion over 41 mm was associated with late aortic events.

Abstract
PURPOSE OF REVIEW In the present review, we discuss the role of CT imaging in the management of aortic dissection, with a particular emphasis on endovascular treatment considerations. RECENT FINDINGS Computed tomography imaging is a fundamental tool in the diagnosis and management of acute and chronic aortic dissection. Its diagnostic accuracy and high resolution contribute to and guide operative strategy. Persistent high mortality for patients who develop aortic dissections suggests a need for innovative diagnostic and treatment strategies. In the recent era, considerable advances have been made in computed tomography (CT) image acquisition, processing, and analysis as well as endovascular technologies with expanded roles in the treatment of aortic diseases.
