Midterm Results of the STABILISE Technique in the Treatment of Aortic Dissection.

: Contemporary treatments of acute aortic dissection, including medical, surgical, and endovascular options, are remarkably effective at the management of malperfusion and rupture. Unfortunately, long-term studies indicate that 30%-50% of patients need secondary procedures to treat progressive aneurysmal enlargement of the untreated aorta. The Stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair (STABILISE) technique was introduced to improve long-term outcomes.

ACT I early feasibility study of the Voyager Ark vascular access device.

Objective: We report the 6-month outcomes of the Ark Cannulation Trial (ACT) I early feasibility study. This investigation examined the Ark as a potential innovative access tool for overcoming cannulation-related challenges and improving arteriovenous fistula (AVF) dependent hemodialysis through targeted cannulation.

Methods: During this first-in-human, interventional, prospective, single arm, single site investigation, 13 patients were treated.

Effect of a novel cannulation device for vascular access on AVF maturation in a goat carotid-jugular fistula model.

Objective: The Ark is a 3-D printed titanium device designed to be implanted around the draining vein of an arteriovenous fistula (AVF) to facilitate vascular access. The purpose of this study was to assess AVF maturation after Ark implantation in a large animal model.

Methodology: End-to-side AVFs were created between the carotid artery and jugular vein in nine pygmy goats that included three control (AVF only) and six experimental (AVF and Ark device) animals.

Clinical Outcomes of Non-Stent-Based Interventions for Symptomatic Below-the-Knee Peripheral Artery Disease in the Excellence in Peripheral Artery Disease (XLPAD) Registry.

For endovascular treatment of below-the-knee (BTK) peripheral artery disease (PAD), independently adjudicated real-world outcomes comparing non-stent-based balloon angioplasty (percutaneous transluminal angioplasty) and adjunctive treatments with or without a concomitant ipsilateral femoropopliteal (FP) artery intervention are scarce. A total of 1,060 patients from the multicenter XLPAD registry who underwent non-stent-based BTK PAD intervention between 2006 and 2021 were included. The primary outcome was the 1-year incidence of major adverse limb events (MALEs), a composite of all-cause death, any amputation, or clinically driven repeat revascularization.

Ruminant model for hemodialysis cannulation.

Background: Preventative strategies that minimize hemodialysis access complications remain limited.

Objective: This study aimed to address this gap by developing a Caprine cannulation model to investigate the impact of repeated cannulations on vascular access patency rates.

Research Design And Measures: In this pilot study, a meta-analysis was conducted using experimental control data from four trials to explore the impact of Caprine breed (independent variable) on the dependent variables that affect hemodialysis cannulation, including AVF growth, AVF depth, and flow rate.

Technique of percutaneous closure of an endovascular arteriovenous fistula created for dialysis access.

Endovascular arteriovenous fistulas (eAVFs) are a new and less invasive type of creation for dialysis access. The anastomosis for eAVFs often occurs between the ipsilateral proximal radial artery and vein or proximal ulnar artery and vein. As eAVF creations are in locations that are not traditionally used for surgical AVF creations, the question of how to approach reversal of these fistulas arises.

Hemodialysis Arteriovenous Access Cosmesis Scale (AVACS): A new measure for vascular access.

Rationale And Objective: This study aimed to develop a cosmesis scale to evaluate the cosmetic appearance of hemodialysis (HD) arteriovenous (AV) accesses from the perspective of the patient and clinician, which could be incorporated into clinical trials.

Study Design: Using a modified Delphi process, two AV access cosmesis scale (AVACS) components were developed in a four-round Delphi panel consisting of two surveys and two consensus meetings with two rounds of patient consultation.

Setting And Participants: The Delphi panel consisted of 15 voting members including five interventional or general nephrologists, five vascular surgeons, three interventional radiologists, and two vascular access nurse coordinators.

Effects of radiation and MediPort placement on the development of thoracic outlet syndrome.

We present a patient who exemplifies the interplay of factors contributing to the development of venous-type thoracic outlet syndrome. The patient was treated with both radiation and chemotherapy for squamous cell carcinoma in the head and neck region; radiation and chemotherapy have been known to damage the vascular system. Multimodality treatment is necessary to achieve good long-term results in these complex patients.

Diaphragmatic fenestrations seen after peritoneal dialysis catheter placement: A rare cause of hydrothorax.

This case report summarizes the clinical course of a patient who developed diaphragmatic fenestrations leading to hydrothorax after the initiation of peritoneal dialysis. We will discuss the interesting disease process in the setting of patient presentation, diagnosis, treatment, and outcome.

Effectiveness of exclusion of a persistent sciatic artery aneurysm with an Amplatzer™ plug.

Persistent sciatic artery is a rare developmental anomaly. In its complete form, it provides the major arterial supply to the lower leg since the femoral system is hypoplastic. These unique arteries are prone to aneurysm formation and most commonly present with complications related to aneurysm formation, which can lead to limb loss.

Critical lower limb ischemia from an embolized Angio-Seal closure device.

Vascular closure devices were introduced in the early 1990s in an effort to reduce time to hemostasis, enable early ambulation, and improve the comfort of patients undergoing femoral artery access for endovascular procedures. Many of these devices leave a foreign component in or around the artery, which can lead to complications such as hematoma, pseudoaneurysm, infection, or limb ischemia. Here we present a case where device embolization led to arterial occlusion and critical limb ischemia.

Thermoregulatory catheter-associated inferior vena cava thrombus.

The use of thermoregulatory catheters (TRCs) in critically ill patients has become increasingly popular. TRCs have been shown to be effective in regulating patient body temperature with improved outcomes. Critically ill patients, especially multitrauma patients and those with femoral catheters, are at high risk for deep vein thrombosis (DVT).

Obstruction of the celiac axis resulting in a pancreaticoduodenal artery aneurysm.

A 47-year-old woman complained of abdominal pain, and a computed tomography scan indicated compressive obstruction of the celiac axis and a 4-cm retropancreatic aneurysm. An angiogram identified the aneurysmal vessel as the posterior pancreaticoduodenal artery. All foregut structures were supplied by this aneurysmal vessel.

Randomized comparison of percutaneous Viabahn stent grafts vs prosthetic femoral-popliteal bypass in the treatment of superficial femoral arterial occlusive disease.

Objective: This randomized prospective study was designed to compare the effectiveness of treating superficial femoral artery occlusive disease percutaneously with expanded polytetrafluoroethylene (ePTFE)/nitinol self-expanding stent grafts vs surgical femoral-to-above knee (AK) popliteal artery bypass with synthetic graft material.

Methods: From March 2004 to May 2005, 100 limbs in 86 patients with femoral-popliteal arterial occlusive disease were identified. Patients had symptoms ranging from claudication to rest pain, with or without tissue loss, and were prospectively randomized for treatment into one of two groups.
