The history of proximal carotid protection and flow reversal to prevent stent angioplasty embolization.

Semin Vasc Surg 2018 Mar 7;31(1):9-14. Epub 2018 Mar 7.

Department of Interventional Radiology, Medical University of South Carolina, Charleston, South Carolina.

Innovation in medicine is often driven by the observations of imaginative physicians who are blessed with insatiable curiosity, coupled with the inability to accept technical boundaries, the status quo of patient care, or the acceptance of procedural morbidity. Few examples illustrate this truism better than the physician-originated clinical research that transformed the safety of carotid stent angioplasty over the last 2 decades. Initial clinical application of carotid stenting suggested that proximal protection may be a better approach to prevent embolic stroke during the angioplasty procedure. Read More

Early carotid artery stenting after onset neurologic symptoms.

Semin Vasc Surg 2018 Mar 22;31(1):15-20. Epub 2018 Feb 22.

Department of Surgery, Unit of Vascular and Endovascular Surgery, University of Siena, Viale Bracci, 53100 Siena Siena, Italy.

Multicenter clinical trials level 1 evidence favors the application of carotid endarterectomy in symptomatic patients, especially the in the elderly cohort. Carotid artery stenting has been proposed as a possible early alternative in selected patients after onset of ipsilateral neurologic symptoms. It is well known that treatment of acute stroke is time-dependent in patients with acute ischemic stroke caused by high-grade stenosis of the internal carotid artery, but intensive medical treatment in conjunction with intervention to improve stroke severity and clinical outcomes has not been established.

How to best treat infectious complications of open and endovascular thoracic aortic repairs.

Semin Vasc Surg 2017 Jun - Sep;30(2-3):95-102. Epub 2017 Nov 14.

Department of Vascular Surgery, Vita-Salute University School of Medicine, San Raffaele Scientific Institute, Via Olgettina 60, 20132, Milano, Italy.

Infectious complications of open and endovascular procedures for descending thoracic aortic disease are relatively rare, affecting 1% to 6% of treated patients. However, the number of thoracic aortic procedures, especially endovascular, is increasing continuously, and infectious complications involving the graft or endograft have been observed more frequently in recent years. Several causative factors may play a role in thoracic aortic prosthetic infections, including hematogenous seeding, local bacterial translocation, and iatrogenous contamination. Read More

Management of the infected aortic endograft.

Semin Vasc Surg 2017 Jun - Sep;30(2-3):91-94. Epub 2017 Nov 14.

Division of Vascular and Endovascular Surgery, Department of Surgery, Chiang Mai University Hospital, Chiang Mai 50200, Thailand.

Although the incidence of abdominal and thoracic aortic endograft infection is infrequent, ranging between 0.2% and 5%, stent-graft infection carries significant morbidity and mortality and exemplifies a formidable therapeutic challenge. The treatment goal is to eradicate the infectious process by endograft explantation, regional tissue debridement, and arterial reconstruction by either an extra-anatomic or in situ grafting procedure using autologous vein, cryopreserved allograft, or antibiotic-soaked prosthetic grafts.

Pathology of graft and stent-graft infections: Lessons learned from examination of explant materials.

Semin Vasc Surg 2017 Jun - Sep;30(2-3):70-74. Epub 2017 Oct 22.

Department of Vascular Surgery and Kidney Transplantation, University Hospital of Strasbourg, 1 Place de l'hôpital, BP 426, 67091 Strasbourg Cedex, France; European Group for Research on Prostheses Applied for Vascular Surgery (GEPROVAS), Strasbourg, France.

Due to the aging population, the number of patients treated with aortic grafts or endografts continues to increase. Although infection after these procedures is uncommon, aortic graft infection is a life-threatening condition, and refinement of management guidelines based on implant pathophysiology is appropriate. In the early 1990s, our European collaborative retrieval program, European Group for Research on Prostheses Applied for Vascular Surgery (GEPROVAS) was commissioned to analyze the degenerative phenomenon occurring on explanted grafts or endografts.

Percutaneous drug-eluting balloon angioplasty to treat dialysis access stenosis.

Semin Vasc Surg 2017 Jun - Sep;30(2-3):67-69. Epub 2017 Oct 18.

Vascular Surgery Unit, Bianchi-Melacrino-Morelli Hospital, Via Melacrino 1, Reggio Calabria, Italy.

A common complication of arteriovenous fistula for hemodialysis is development of conduit stenosis, which compromises function and can result in access thrombosis. Possible treatment options include open repair and endovascular therapy, with the latter preferred due to lower morbidity and similar outcomes. Recurrence of conduit stenosis is common and, based on the pathophysiology of this lesion, the application of drug-coated balloon angioplasty is attractive. Read More

Stroke Prevention and Atherosclerosis Research Centre, Robarts Research Institute, Western University, 1400 Western Road, London, Ontario, Canada N6G 2V4. Electronic address:

In the United States, 90% of carotid intervention is being performed for asymptomatic carotid stenosis, even though 90% of patients would be better treated with intensive medical therapy. This is being justified by comparing risks of stroke or death with medical therapy during clinical trials completed decades ago (approximately 2% per year) with risks of intervention with carotid artery stenting (CAS) versus carotid endarterectomy in recent trials that did not have a medical arm. Such extrapolations are, simply put, invalid. Read More

Imaging of the high-risk carotid plaque: magnetic resonance imaging.

Semin Vasc Surg 2017 Mar 27;30(1):54-61. Epub 2017 Apr 27.

University of Washington Vascular Imaging Lab, Department of Radiology, 850 Republican Street, Seattle, WA 98109. Electronic address:

The emergence of the concept of high-risk atherosclerotic plaque has led to considerable interest in noninvasive imaging techniques to identify high-risk features before clinical sequelae. For plaques in the carotid arteries, magnetic resonance imaging has undergone considerable histologic validation to link imaging features to indicators of plaque instability, including plaque burden, intraplaque hemorrhage, fibrous cap disruption, lipid rich necrotic core, and calcification. Recently introduced imaging technologies, especially those focused on three-dimensional imaging sequences, are now poised for integration into the clinical workup of patients with suspected carotid atherosclerosis.

Imaging of high-risk carotid plaques: ultrasound.

Semin Vasc Surg 2017 Mar 27;30(1):44-53. Epub 2017 Apr 27.

Center for Vascular Diagnostics, Division of Vascular Surgery, University of Maryland School of Medicine, 22 South Greene Street, S10-B00, Baltimore, MD 21201; Vascular Service, Veterans Affairs Medical Center, Baltimore, MD. Electronic address:

Duplex ultrasonography has a well-established role in the assessment of the degree of stenosis caused by carotid atherosclerosis. This assessment is derived from Doppler velocity changes induced by the narrowing lumen of the artery. New research into the mechanisms for plaque rupture and atheroembolic stroke indicates that the degree of narrowing is an imperfect predictor of stroke risk, and that other factors, such as plaque composition and remodeling and biomechanical forces acting on the plaque, can play a role.

CVPath Institute, Inc, 19 Firstfield Road, Gaithersburg, MD 20878. Electronic address:

The pathophysiology and natural history of atherosclerotic carotid disease is predicated on a more extensive knowledge of lesion progression gained in the studies conducted in the coronary arteries, and these will be reviewed. While the precise sequence of lesion progression leading to carotid plaque vulnerability and cerebrovascular events remain less well understood, specific early and more advanced progressive lesion morphologies associated with stroke risk have been characterized. Of late, there has been a conscious effort for stroke prevention in symptomatic and asymptomatic patients to move beyond luminal stenosis as the only guidance to predict future cerebrovascular events.

Will mesh-covered stents help reduce stroke associated with carotid stent angioplasty?

Semin Vasc Surg 2017 Mar 27;30(1):25-30. Epub 2017 Apr 27.

Division of Vascular Therapy, Kaiser Foundation Hospital and Department of Surgery, Tripler Army Medical Center, 3288 Moanalua Road, Honolulu, HI 96819. Electronic address:

Carotid stent angioplasty (CAS) has been shown to protect patient from future stroke long-term efficacy similar to carotid endarterectomy (CEA). The risk of minor stroke in the perioperative period is higher than with CEA and not related to cerebral protection during the CAS procedure since a significant portion of the neurologic events occur between 1 and 30 days following stent deployment. This observation suggests mechanisms integral to the stent itself may be pertinent such as plaque embolization thru the stent struts may occur. Read More

Patient selection for endovascular sac sealing of abdominal aortic aneurysm.

Semin Vasc Surg 2016 Sep 4;29(3):93-101. Epub 2016 Nov 4.

Department of Radiology, Royal Liverpool University Hospital, Liverpool, UK.

Endovascular sealing is a developing technique for treatment of abdominal aortic aneurysm that draws on novel concepts utilizing polymer filling of endobags within the aorto-iliac lumen. The morphologic indications and patient selection, while similar to those of endovascular aneurysm repair, differ in some regards. The Instructions for Use for the Nellix sealing device may expand the indications for aneurysm treatment and are closely scrutinized in this article. Read More

Percutaneous interventions following endovascular aneurysm sac sealing: Endoleak embolization and limb-related adverse events.

Semin Vasc Surg 2016 Sep 5;29(3):135-141. Epub 2016 Nov 5.

Department of Radiology, St George׳s Hospital, Blackshaw Road, London, SW17 0PZ, UK.

The Nellix endovascular aneurysm sealing system is a novel alternative to conventional endovascular aneurysm repair for aortic aneurysm management using paired balloon-expandable endografts supported by polymer-filled endobags to achieve sealing and anatomic fixation. Part of the promise of endovascular aneurysm sealing is increased resistance to lateral and longitudinal forces and a potential for reduced rates of device-related failures, particularly endoleaks. Initial efficacy data on this device are encouraging, but our knowledge of its associated complications and their management is limited. Read More

Appearance of the Nellix endoprosthesis on postoperative imaging: implications for patient and device surveillance.

Semin Vasc Surg 2016 Sep 17;29(3):126-134. Epub 2016 Jul 17.

Department of Radiology, Cambridge University Hospitals NHS Foundation Trust, Cambridge, UK.

The Nellix stent graft has novel features that influence interpretation of imaging follow-up, in particular, the use of endobags that seal the aneurysm sac. The polymer within the endobags contains a small amount of contrast medium, which causes a predictable temporal change in appearances. Understanding of these features allows correct image evaluation.

Extended use of endovascular aneurysm sealing: Chimneys for juxtarenal aneurysms.

Semin Vasc Surg 2016 Sep 5;29(3):120-125. Epub 2016 Nov 5.

St George's Vascular Institute, St George's Hospital, Blackshaw Road, London SW17 0QT, UK.

Hostile infrarenal aortic neck anatomy presents a challenge for the endovascular treatment of abdominal aortic aneurysm. Open surgical repair has been seen as the gold standard treatment for juxtarenal abdominal aortic aneurysm; however, endovascular techniques are now becoming more prevalent, particularly in patients deemed high risk for morbidity and mortality with open repair. The morphology of an aneurysm is a determinant of long-term outcomes, and short aneurysm necks are associated with poorer outcomes and a higher rate of secondary reinterventions. Read More

Treating iliac aneurysm using the Nellix Endovascular Sac Sealing System.

Semin Vasc Surg 2016 Sep 5;29(3):114-119. Epub 2016 Nov 5.

Department of Cardiothoracic and Vascular Surgery, Medical Center of the Johannes Gutenberg-University Mainz, Langenbeckstr. 1 55131 Mainz, Germany.

As endovascular treatment of abdominal aortic aneurysms has become established, there has been growing focus on treatment of the aneurysmal iliac artery. Isolated, large iliac aneurysms >30 mm pose a risk of rupture, but, in addition, 20% to 30% of abdominal aortic aneurysms are associated with iliac aneurysmal dilatation, which can compromise long-term outcomes. Endovascular solutions are evolving and until recently have utilized standard stent graft technology. Read More

Endovascular Program, BocaCare Vascular Surgery, Boca Raton Regional Hospital, 670 Glades Road, Suite 300, Boca Raton, FL 33431. Electronic address:

The aortic arch is one of the most anatomically complex segments of the thoracoabdominal aorta due the plurality of vital branch configurations, intrinsic and highly variable three-dimensional curvature, and involvement in a variety of thoracic aortic pathologies, such as aneurysmal degeneration, penetrating ulcer, and media wall dissection. Pathologies that extend the repair proximal to the left common carotid artery require more complex branch vessel management beyond a carotid-subclavian bypass. This article will review the current status of branched aortic arch endografts. Read More

Snorkel endovascular abdominal aortic aneurysm repair versus fenestrated endovascular aneurysm repair: is it a competition?

Semin Vasc Surg 2016 Mar 12;29(1-2):68-73. Epub 2016 Jul 12.

Division of Vascular and Endovascular Surgery of University of South Florida College of Medicine, Tampa, FL. Electronic address:

The endovascular treatment of juxtarenal abdominal aortic aneurysm (AAA) can be performed by either a standard endovascular stent graft with additional snorkle grafts to aorta branches (snorkel endovascular aneurysm repair) or implantation of a fenestrated stent graft (fenestrated endovascular aneurysm repair). While many vascular surgeons consider snorkel endovascular aneurysm repair and fenestrated endovascular aneurysm repair to be competing techniques or alternate strategies, published procedural outcomes suggest more complementary roles. In this clinical review, the advantages and disadvantages of these two approaches are debated, as much can be learned from both strategies. Read More

Vascular Surgery Department, The Cleveland Clinic, 9500 Euclid Avenue, Cleveland, OH 44195.

Clinical outcome reports document that from 30% to 60% of endovascular aneurysm repair procedures are performed outside of US Food and Drug Administration-approved Instruction for Use, or "off label." Endovascular aneurysm repair performed outside of Instruction for Use has a significantly higher rate of device failure, potentially requiring device reintervention and even planned or emergent explant. The Nellix device has the potential to reduce the rate of aneurysm device failure through its novel design. Read More

Department of Vascular Surgery, MedStar Health, 110 Irving Street NW, Washington, DC 20010.

Endovascular aneurysm repair has enabled a broad population of patients with infrarenal abdominal aortic aneurysm to be treated by a less-invasive technique. However, endovascular aneurysm repair has therapeutic limitations, including the need for lifelong surveillance and a higher rate of secondary interventions than open repair. These outcomes can promote patient dissatisfaction and result in increased health care costs and associated morbidity and mortality. Read More

Endovascular aneurysm repair (EVAR) has revolutionized the treatment of abdominal aortic aneurysm (AAA). However, persistent AAA sac endoleak following EVAR can result in sac diameter increase requiring re-intervention in up to one-third of cases and even result in aneurysm rupture. In this case review, we summarize and detail endovascular re-interventions for each type of endoleak. Read More

Treatment paradigms for elective repair of asymptomatic abdominal aortic aneurysms (AAA) have evolved during the past 2 decades, with endovascular aneurysm repair as the preferred treatment modality. The patient care strategy for emergent treatment for ruptured AAA is not as straightforward, due in part to surgeon expertise and stent-graft availability at the institution. Although most reports have extrapolated elective endovascular aneurysm repair feasibility data to the ruptured AAA patient and the aneurysm anatomy, these expectations should be interpreted with caution.

Overview of aortic aneurysm management in the endovascular era.

Semin Vasc Surg 2016 Mar 15;29(1-2):3-17. Epub 2016 Jul 15.

Division of Vascular and Endovascular Surgery, University of South Florida Health, Morsani College of Medicine, 2 TGH Circle, STC 7016, Tampa, FL 33606.

Management of aortic aneurysm disease has changed in the endovascular era, with the majority of patients opting for stent-graft repair of abdominal and thoracic aneurysms. An understanding of this vascular condition is important for primary care, emergency medicine, medicine specialists, and vascular surgeons alike. Awareness of the patient risk factors for aneurysmal degeneration, sac rupture, and medical management allows physicians to screen appropriate patient populations, which decreases aneurysm-related mortality due to rupture.
