Updates on the Utilization of Percutaneous Deep Vein Arterialization in End-Stage Peripheral Arterial Disease.

Progressive peripheral artery disease, especially in the tibial and pedal vessels, can severely limit the interventions that vascular surgeons and interventionalists can provide to patients. End-stage peripheral arterial disease is often described as a disease where there are no distal targets available in the foot. Traditionally, amputation has been the only option for these patients.

Management and Treatment of Tandem Carotid Lesions.

Background: Tandem lesions of the proximal aortic branch vessels and carotid bifurcation are uncommon. While management strategies vary, a hybrid approach of carotid endarterectomy with retrograde common carotid artery (CCA) or innominate artery (IA) stenting has become a mainstay of treatment. The purpose of this article was to provide a review of the literature, discuss alternative treatment modalities, and highlight technical considerations of the hybrid approach.

Appropriate Use Criteria Committees: The professional society role in the development and implementation of Appropriate Use Criteria.

Vascular surgeons have the ability to manage and intervene on numerous vascular diseases of both the arterial and venous systems. With the growing number of interventions available as endovascular technology evolves, it is important to determine when a procedure is safely indicated for a vascular surgery patient. Appropriate Use Criteria (AUC) offer synthesized clinical information and practice standards that can aid clinicians in making these management decisions.

A hybrid endovascular and open approach to rare thyrocervical trunk and subclavian pseudoaneurysms complicated by embolic brachial artery occlusion.

Subclavian and thyrocervical trunk pseudoaneurysms are rare pathologies and even more so when they occur simultaneously. Treatment of these vascular injuries can be done endovascularly or with open surgery. We present a novel two-stage, hybrid open and endovascular approach to the management of a healthy 41-year-old man with no personal or family history of connective tissue disorders, who presented with subclavian branch and thyrocervical trunk pseudoaneurysms complicated by brachial artery occlusion.

Single Center Outcomes of Percutaneous Deep Vein Arterialization in Patients with End-Stage Peripheral Artery Disease.

Peripheral artery disease (PAD) can present as chronic limb threatening ischemia (CLTI) with ischemic pain and tissue loss. Progression of distal disease can lead to a "no option" or end-stage disease without traditional open or endovascular revascularization due to lack of pedal targets. Innovations in endovascular technology allow for the use of percutaneous deep vein arterialization (pDVA) to treat patients with CLTI.

Understanding and addressing varying perceptions of autonomy.

Recently, there has been a major shift in the concept of resident autonomy in the operating room. As a result, surgical residents' independence has decreased during their training years. This change has been secondary to multiple factors, including fragmented attending resident interactions, hospital demands for productivity, operating room efficiency, and the public's perception of resident participation in surgery.

Technological Advances to Address the Challenging Abdominal Aortic Aneurysm Neck.

There have been significant technologic advances in endovascular aortic therapies since the introduction of conventional infrarenal endovascular aortic aneurysm repair (EVAR). These advances have sought to address the weaknesses of conventional EVAR- particularly the difficult or "hostile" infrarenal aortic aneurysm neck. We review anatomical features that create a hostile neck and the most recent advancements to overcome these limitations.

Treatment of a descending thoracic mycotic aneurysm secondary to disseminated aspergillosis infection with thoracic endovascular aortic repair.

Mycotic aortic aneurysms are a rare and potentially fatal aortic pathology. Advancements in vascular technology have allowed endovascular repair to be a durable and less invasive option for the treatment of mycotic aortic aneurysms. We have presented the case of a 51-year-old man with a mycotic aneurysm of the descending thoracic aorta secondary to chronic, disseminated aspergillosis infection after liver transplantation.

The Feasibility and Applicability of Percutaneous Deep Vein Arterialization in Peripheral Artery Disease.

Peripheral artery disease (PAD) can often present with chronic limb threatening ischemia (CLTI), including ischemic rest pain and severe tissue loss. Progression of PAD can lead to "no option" or end-stage disease in which there are no traditional open or endovascular interventions available for revascularization. This cohort of patients have a poor prognosis, with a major amputation rate of 40% and mortality of up to 20% at six months.

Spontaneous compartment syndrome and endovascular repair of tibioperoneal trunk pseudoaneurysm in Ehlers-Danlos syndrome.

Vascular Ehlers-Danlos syndrome is caused by mutations in the COL3A1 (collagen type III alpha-1) gene, resulting in loss of integrity of arteries and hollow organs. Patients are predisposed to dissection, aneurysm, and organ rupture. The median life expectancy is ∼51 years.

Thoracic Aortic Endografts: Past, Present, and Future.

Introduction: Thoracic endovascular aortic repair (TEVAR) has become first-line therapy for a wide range of thoracic aortic pathologies including traumatic thoracic aortic injury, type B aortic dissection, intramural thoracic aortic hematoma, and penetrating aortic ulcers. This study aims to analyze the progress made of thoracic stent graft devices, review the current Food and Drug Administration (FDA)-approved devices, and discuss the future technological advances.

Materials And Methods: In this paper, we will review the history of TEVAR and the development of the first iteration of devices.

The Current Role of the Percutaneous Arteriovenous Fistula for Hemodialysis Access.

Dialysis is the preferred treatment for patients with end-stage renal disease (ESRD) for the removal of accumulated toxins secondary to compromised renal function. Hemodialysis has traditionally been performed via a surgically created arteriovenous fistula (AVF) or arteriovenous graft (AVG). Novel endovascular techniques have allowed for the creation of percutaneous arteriovenous fistulas for hemodialysis access.

Preparation of N-(2-alkoxyvinyl)sulfonamides from N-tosyl-1,2,3-triazoles and Subsequent Conversion to Substituted Phthalans and Phenethylamines.

Decomposition of N-tosyl-1,2,3-triazoles with rhodium(II) acetate dimer in the presence of alcohols forms synthetically versatile N-(2-alkoxyvinyl)sulfonamides, which react under a variety of conditions to afford useful N- and O-containing compounds. Acid-catalyzed addition of alcohols or thiols to N-(2-alkoxyvinyl)sulfonamide-containing phthalans provides access to ketals and thioketals, respectively. Selective reduction of the vinyl group in N-(2-alkoxyvinyl)sulfonamide-containing phthalans via hydrogenation yields the corresponding phthalan in good yield, whereas reduction with sodium bis(2-methoxyethoxy)aluminumhydride generates a ring-opened phenethylamine analogue.
