PURPOSE: To compare the technical and clinical outcomes of fenestrated thoracic endovascular aortic repair (F-TEVAR) and chimney thoracic endovascular aortic repair (CH-EVAR) of aortic disease. METHODS: PubMed, Embase and Cochrane databases were systematically searched to identify studies on the management of thoracic aortic pathologies using chimney or fenestrated techniques published between 2000 and 2022. Individual studies provided at least one of the following essential outcomes: technical success, immediate and follow-up type I endoleak, 30-day and aorta-related mortality, cerebral events and supra-aortic branch patency...

PURPOSE: To assess the safety, technical success, and midterm outcomes of Heli-FX EndoAnchor (Medtronic) deployment in thoracic or abdominal endovascular aortic repair (TEVAR or EVAR). MATERIALS AND METHODS: Single institution, retrospective study of all EndoAnchor procedures from 2/1/2017 to 3/30/2021. All procedures were performed percutaneously by Interventional Radiologists. Clinical information and outcome data were retrieved from electronic medical records...

BACKGROUND: Although endovascular technology has resulted in a paradigm shift in treatment, medical management remains the standard of care for penetrating aortic ulcer (PAU) and intramural hematoma (IMH). This study aimed to detail the short- and long-term outcomes of symptomatic PAU/IMH. METHODS: Institutional data on symptomatic PAU/IMH were gathered (2005-2020). The primary outcome was the composite of recurrent symptoms, radiographic progression, intervention, rupture, and death from related or unknown cause...

AIM: Multisegmented aortic pathologies present challenging issues independent of the treatment chosen. Whether open or endovascular, staged, or simultaneous, every treatment modality has its own pros and cons. We revealed our patients retrospectively with early and mid-term results who had simultaneous endovascular thoracic and abdominal aortic repair for thoracic aortic pathologies and infrarenal abdominal aortic aneurysm (iAAA) as a single-center experience. MATERIALS AND METHODS: Between January 2016 and January 2021, 16 patients were diagnosed with thoracic aortic pathology, and iAAA was simultaneously repaired in an endovascular manner...

OBJECTIVE: Double-low CT aortography (DLCTA) is increasingly used in follow-up studies of aortic aneurysm after endovascular aneurysm repair (EVAR). However, whether DLCTA can reliably detect the presence of endoleak is not clear. METHODS: From February 2014 to October 2019, patients who received EVAR, underwent CT surveillance, and had at least one standard CTA protocol (120 kVp, 400 mg I/kg) and one DLCTA (70-80 kVp, 200 mg I/kg) were included. The integrated findings of the standard CTA and sequential change were considered as the reference standard for the presence of endoleak...

INTRODUCTION: With increasing regionalization of complex aortic surgery within fewer US centers, patients may face increased travel burden when accessing aortic surgery. Longer travel distances have been associated with inferior outcomes after major surgery, however the impacts of distance on reinterventions and costs have not been described. This study aims to assess the association between patient travel distance and longer-term outcomes including costs and reinterventions after complex aortic surgery...

BACKGROUND: Kommerell's diverticulum (KD) with a right aortic arch (RAA) and aberrant left subclavian artery (aLSCA) is a rare congenital anomaly of the aortic arch. Treatment is not well defined due to its uncommon presentation, with rupture and dissection risk rates of up to 53%. CASE SUMMARY: A 54-year-old male with a history of chronic obstructive pulmonary disease (COPD) and hypertension presented with difficulty breathing during exercise without dysphagia...

OBJECTIVE: Staged endovascular repair of complex aortic aneurysms with first-stage thoracic endovascular aortic repair may decrease the risk of spinal cord ischemia (SCI) associated with fenestrated-branched endovascular aortic repair (FB-EVAR) of thoracoabdominal aortic aneurysms or optimize the proximal landing zone in the cases requiring total aortic arch repair. However, a limitation of multistaged procedures is the risk of interval aortic events (IAEs) including mortality from a ruptured aneurysm...

INTRODUCTION: Endovascular aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR) are established techniques to treat abdominal aortic aneurysms (AAA) and thoracic aortic aneurysms (TAA). However, there are limitations when challenging proximal neck anatomy is present. Heli-FX EndoAnchors have been used in addition to EVAR and TEVAR to improve proximal sealing of a stent-graft, but there are limited data available on their outcomes, safety, and efficacy. AREAS COVERED: The properties and development of Heli-FX EndoAnchors are evaluated...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) of metachronous thoracic aortic aneurysms (M-TAA) following previous infrarenal abdominal aortic aneurysm (AAA) repair has been associated with higher spinal cord ischemia (SCI) risk compared with TEVAR of primary thoracic aortic aneurysms (TAA). However, data on the impact of the type of prior infrarenal aortic repair on outcomes are scarce. In this study, we examined perioperative outcomes and long-term mortality following TEVAR M-TAA compared with primary TEVAR of TAA...

To the best of our knowledge, the present report is the first on the safety and efficacy of complete endovascular aortic reconstruction from zone 0 to 10 using a standardized approach and parallel stent graft configurations in high-risk patients considered unfit for surgery. During a 7-year period, five patients with complex thoracoabdominal aortic aneurysms and dissections involving zone 0-10 presented with rupture (n = 1; 20%), were symptomatic (n = 2; 40%), or had an aortic pseudoaneurysm (n = 2; 40%) and underwent complete endovascular zone 0-10 reconstruction using off-the-shelf stent grafts in parallel configurations that included chimneys, periscopes, and endovascular docking stations...

Endoleaks represent a main issue of endovascular approach of thoracic aorta diseases and their treatment continue to be challenging. According to some authors, type II endoleaks sustained by intercostal arteries should not be treated because of the technical difficulties. However, the persistence of a pressurized aneurysmal may confer an ongoing risk of enlargement and/or aortic rupture. We describe the successful treatment of type II endoleak in two patients with an intercostal artery's access. In both cases, the endoleak was discovered during follow-up and was treated with its direct coil embolization under local anesthesia...

PURPOSE: Percutaneous access for endovascular aneurysm repair (EVAR) is commonplace, with its attendant benefits. The combination of continued reduction in device profile and evolution of vascular closure device (VCD) design drives successful and safe percutaneous EVAR. A new such VCD is the MANTA Large-Bore Closure Device designed in two iterations for closure of arterial defects from 10 to 25F. We present a prospective audit of 131 large-bore femoral closures using an 'all-comers' approach to device selection...

OBJECTIVE: Endovascular aortic aneurysm repair has lower rates of postoperative mortality and morbidity when compared with open repair. However, endovascular repair still carries the risk of postoperative dialysis, paralysis, and stroke. This study examined the rates of postoperative mortality and morbidity stratified by type of endovascular aortic aneurysm repair. METHODS: All patients who underwent endovascular aortic aneurysm repair in the Vascular Quality Initiative registry from January 2011 - May 2022 were identified...

INTRODUCTION: Postoperative renal function decline is a major concern for thoracic endovascular aortic repair (TEVAR) and endovascular abdominal aortic repair (EVAR). Diluting contrast medium in the power injector may be helpful in reducing the risk of contrast-induced nephropathy, but it can also blur fluoroscopic vision during surgery. The quality of the current evidence is very low; thus, this study is designed to investigate the effect of contrast dilution in the power injector on renal function changes in patients after endovascular aortic repair...

OBJECTIVE: Recently evolving practice patterns in complex aortic surgery have led to regionalization of care within fewer centers in the United States, and thus patients may have to travel farther for complex aortic care. Travel distance has been associated with inferior outcomes after non-vascular surgery, particularly non-index readmission. This study aims to assess the impact of patient travel distance on perioperative outcomes and readmissions after complex aortic surgery. METHODS: A retrospective review was conducted of all patients in the Vascular Quality Initiative and Vascular Implant Surveillance and Interventional Outcomes Network databases undergoing complex endovascular aortic repair (EVAR) including internal iliac or visceral vessel involvement, complex thoracic endovascular aortic repair (TEVAR) including zone 0 to 2 proximal extent or branched devices, and complex open abdominal aortic aneurysm (AAA) repair including suprarenal or higher clamp sites...

OBJECTIVES: Patients with Marfan syndrome are usually not suitable for endovascular repair of the thoracoabdominal aorta. This study was designed to analyze our center's experience with open surgical thoracoabdominal aortic replacement in Marfan patients. METHODS: This was a retrospective study with prospective follow-up. Between January 1995 and September 2021, a total of 648 patients underwent thoracoabdominal aortic replacement at our center. Of these, 60 had Marfan syndrome and were included in this study...

BACKGROUND: Behcet's disease (BD), originally described by Hulusi Behcet in 1937, is a chronic relapsing inflammatory process of an immunologic syndrome and the involvement of the vascular system is called Vasculo-Behcet disease (VBD). This is a retrospective study evaluating 21 patients diagnosed with VBD who underwent endovascular treatment. METHODS: This single-center study was conducted between January 2016 and January 2022. Early and mid-term endovascular outcomes of a total of 21 patients (16 males, 5 females with a median age of 42 years; range, 31 to 46 years), with a diagnosis of VBD, who underwent endovascular arterial repair in our hospital, were retrospectively analyzed...

Today's vascular surgeon must navigate their practice through a field of ever-advancing technology while maintaining knowledge of open techniques that remain equally important in the care of their patients. In this article, the authors provide insight into the perioperative decision-making that goes into choosing a surgical plan for each patient based on their disease process, anatomy, nonmodifiable risk factors, and other comorbidities.

PURPOSE: Most blunt thoracic aortic injuries (BTAIs) may be treated using thoracic endovascular aortic repair (TEVAR), and most blunt abdominal traumas (BATs) are managed conservatively. We hypothesized that severe trauma that needs TEVAR may increase the risk of delayed intra-abdominal hemorrhage in patients with concomitant BTAI and BAT because of the potential hemorrhagic shock, disseminated intravascular coagulopathy, blood loss, consequent need for blood transfusion, and procedure-associated heparinization...
