Nathan K Itoga, Ga-Young Suh, Christopher P Cheng
The Nellix device utilizes polymer filled endobags to stabilize the abdominal aortic aneurysm (AAA) sac described as endovascular aneurysm sealing (EVAS). We analyzed cardiac gated CTA scans of repaired AAA with EVAS in four patients to evaluate geometry and cardiac pulsatility-induced deformation. Graft translation and aortic curvature changes were found to be minimal during the cardiac cycle. The mean±SD changes in renal-aorta angles (1.0±0.9°) were less than the changes in the SMA-aorta angle (4.0±2...

Three cases of internal carotid artery (ICA) injury during endoscopic endonasal surgery were analyzed, including 1 case of recurrent malignancy of sphenoid sinus, 1 case of intraorbital meningioma and 1 case of optic neuropathy. Salvage sphenoid sinus packing with gauze strip was managed in all the three cases. One patient operated a permanent closure of the carotid system intraoperatively and died after surgery. Among 2 survival cases, one patient accepted the endovascular embolization subsequently; the other patient was cured by intravaseular stent graft implantation without craniocerebral or ocular complicatitms...

BACKGROUND:  Post-coarctation of the aorta (CoA) pseudoaneurysms is a complication of open repair. Thoracic endovascular repair (TEVAR) is feasible but complicated by proximity to the supra-aortic trunks and severe arch angulation. METHODS:  We describe three cases of post-CoA pseudoaneurysms treated with custom-made Relay stent grafts (Vascutek, Scotland). RESULTS:  Technical and clinical success was achieved in all three cases with no mortality, morbidity, endoleaks, or complications...

OBJECTIVE: Aortic stent-graft infection is rare, but remains one of the most challenging and threatening complications. This systematic review aimed to identify the clinical features, treatment and outcomes of endograft infection after abdominal endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR). METHODS: A systematic literature review of all published literature from January 1991 to September 2016 on stent-graft infection was performed under the instruction of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)...

The persistent sciatic artery (PSA) is a remnant of the fetal circulatory system that is preserved in less than 0.1% of the population. Up to 60% of patients with this vascular anomaly will go on to development of a PSA aneurysm (PSAA), which can produce a variety of symptoms including neuropathy, claudication, and acute limb-threatening ischemia. Historical management is by open operation and interposition grafting, which can be highly morbid. We describe successful management of a large, symptomatic PSAA by endovascular stent-grafting with intermediate term follow-up...

Management of Type 1A endoleaks can be challenging. In the endovascular era, this condition is expected to become more frequent. Conventionally, surgical explant of the endograft remains the "last resort" surgical treatment when all endovascular or other open options are exhausted. Endograft removal is a difficult and morbid procedure. An alternative technique is described that involves cinching the endograft following disengagement of the proximal fixation hooks. The endograft is re-deployed within a prosthetic aortic replacement graft with an overlapping zone...

Preservation of the residual hypogastric artery (HGA) in patients with previous endovascular aortic aneurysm repair (EVAR) may require complex operative strategies. We report an alternative technique to preserve the residual HGA with the Gore Excluder Iliac Branch endoprosthesis (IBE) in urgent situations. MethodsWe report the case of two high-risk patients (unfit for open surgery), with previous EVAR and exclusion of one HGA, treated in emergency setting. Both patients met the anatomical requirements for Gore IBE use...

BACKGROUND: Although iodinated contrast (IC) agents are commonly used in endovascular aneurysm repair (EVAR), perioperative use in patients with renal dysfunction or IC allergies is avoided. Carbon dioxide (CO2 )-guided angiography is a promising alternative. We aimed to evaluate short-term and mid-term outcomes of EVAR using CO2 -guided angiography. METHODS: Three hundred and eighty-one patients who underwent EVAR from January 2012 to September 2016 were retrospectively reviewed and divided into an IC-EVAR group (n=351) and CO2 -EVAR group (n=30)...

Penetrating aortic ulcer (PAU) is an acute aortic syndrome that can proceed to life-threatening aortic dissection or even aortic rupture. Isolated iliac aneurysms are relatively rare and often asymptomatic due to their deep pelvic location but are frequently associated with high mortality with rupture. We report a case of a 68-year-old man with a symptomatic penetrating ulcer in the descending aorta and an asymptomatic right iliac aneurysm involving the common and internal iliac arteries. The patient was successfully treated by endovascular repair in a single-stage manner using stent grafts in the descending aorta and right common iliac artery after coil embolization of the right internal iliac artery...

We describe the successful surgical treatment of a 71-year-old man affected by right buttock claudication after a right internal iliac artery (IIA) coil embolization as an adjunct to endovascular iliac artery aneurysm repair. Computed tomography angiography revealed extensive aortoiliac calcifications and thrombus in the vessel walls. Despite patency of the contralateral IIA and preservation of right distal collateral flow through ipsilateral hypogastric branches, the symptom was persistent and disabling. The high-risk patient underwent an "open" repair of the infrarenal abdominal aneurysm with removal of the entire stent-graft and concomitant revascularization of the right IIA...

OBJECTIVES: Aortic neck diameter is an independent anatomical feature that is poorly understood, yet potentially linked to proximal seal failure and adverse outcome following standard EVAR. The aim of this study was to assess whether large proximal aortic neck (LAN) diameter is associated with adverse outcome using prospectively collected individual patient data from The Global Registry for Endovascular Aortic Treatment (GREAT). METHODS: A total of 3166 consecutive patients, from 78 global centres, receiving Gore Excluder stent grafts for infrarenal abdominal aortic aneurysm repair between 2011 and 2017 were included...

OBJECTIVES: This study aims to report mid-term follow-up outcomes of a series of TAAD patients treated with TEVAR in China. BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has been used to treat type A aortic dissection (TAAD) for years. However, by comparing public reports, their outcomes which were based on different sample sizes show inconsistency. METHODS: Between January 2001 and December 2015, there were 56 patients with TAAD received TEVAR identified in 5 medical centers...

Surgical treatment for distal arch aortic aneurysm is generally invasive, and there is no definitive approach for it. We report 2 cases of men who was admitted for the treatment of aortic aneurysm. First case is a 78-year-old man. Two saccular aneurysm were observed on distal aortic arch and descending aorta by contrast-enhanced computed tomography. Two staged-repair was performed with using the Lupiae vascular graft and thoracic endovascular aortic repair(TEVAR). The postoperative course was uneventful, and he was discharged on day 21 after 1st operation...

The patient was a 66 year-old male. Computed tomography (CT) angiography showed a huge aneurysm(120 mm) in the aortic arch and chronic type B aortic dissection(45 mm) in the descending aorta. Echocardiography showed patent ductus arteriosus( PDA). Because of pulmonary hypertension due to PDA, it was considered unacceptable to put him under general anesthesia twice. We performed thoracic endovascular aortic repair (TEVAR) via the ascending aorta and total arch replacement (TAR) simultaneously to prevent paraplegia...

Endovascular aneurysm repair (EVAR) can involve some unfavorable complications such as endoleaks or stent-graft (SG) migration. Such complications, resulting from the complex mechanical interaction of vascular tissue, SG and blood flow or incompatibility of SG design and vessel geometry, are difficult to predict. Computational vascular mechanics models can be a predictive tool for the selection, sizing and placement process of SGs depending on the patient-specific vessel geometry and hence reduce the risk of potential complications after EVAR...

Thoracic endovascular aortic repair (TEVAR) has been proven to be the optimal therapy for patients with a ruptured descending thoracic aortic pathology. In these emergent settings, TEVAR provides a rapid delivery of treatment to an unstable patient with a lethal disease. Typically, the greatest challenge is maintaining hemodynamic stability until the time of graft deployment. In this report, we describe our technique of performing awake TEVAR for ruptured descending thoracic aortic disease.

BACKGROUND: Mycotic aneurysm is an uncommon disease which could be fatal without appropriate treatment. Although standard therapy for mycotic aneurysms consists of resection of the infected aorta and in situ graft replacement, some treat with endovascular stent-grafting because patients may not tolerate graft replacement due to underlying diseases. There are 6 more reported cases of mycotic aneurysm caused by Edwardsiella tarda. With the exception of our case, all underwent resection and debridement of the infected aorta or vascular prosthesis...

Background: Revascularization of posterior circulation is essential in patients with severe bilateral vertebral artery (VA) stenosis despite administering maximal medical treatment, due to the high mortality of posterior circulation stroke. Case Description: We present a 69-year-old man with bilateral severe VA stenosis at the origins, treated with occipital artery (OA)-distal VA anastomosis. Conclusion: Endovascular treatment and other surgical treatments, such as bypass grafting, are effective, but OA-VA anastomosis is a safe and effective procedure for revascularization of the posterior circulation...

PURPOSE: To describe a novel modification technique to lower the distal radial force of a thoracic stent-graft so as to avert stent-graft-induced new entry tears (SINE) in the fragile aorta of patients with genetic aortic disease and aortic dissection. TECHNIQUE: A commercially available thoracic stent-graft is partially deployed on a back table. The most distal Z-stent is removed, the distal fabric is marked by vascular clips, and the modified stent-graft is reloaded and deployed in the true lumen of an aortic dissection...
