Transitions of frailty after lower extremity interventions for chronic limb-threatening ischemia.

Background: Frailty is common among surgical patients and predicts poor surgical outcomes. This study aimed to analyze transitions in frailty state among patients undergoing lower extremity care for chronic limb-threatening ischemia (CLTI).

Methods: Between 2018 and 2022, all patients undergoing a primary intervention for CLTI (endovascular intervention [EV], bypass [BYP], major amputation [AMP]) or wound care were analyzed.

The Value of Restaging WIfI (Wound, Ischemia, and Foot Infection) After Initial Vascular and Podiatric Intervention.

Background: Wound, ischemia, and foot infection (WIfI) is an important staging system for diabetic patients presenting with chronic limb-threatening ischemia (CLTI) of the lower extremities (LEs). This study examines the clinical implications of restaging WIfI after initial vascular and podiatric interventions.

Methods: A prospective database of patients undergoing vascular intervention treatment of the LE for tissue loss between 2018 and 2022 was queried.

Vascular Complications in Extracorporeal Membrane Oxygenation-A Narrative Review.

The establishment of a peripheral ECMO circuit can lead to significant arterial and venous complications in 10-30% of patients. Vascular complications, particularly acute limb ischemia, are associated with worsening overall outcomes. Limb ischemia occurs significantly more frequently in the early stages of VA ECMO than in VV ECMO.

Pedal medial arterial calcification influences the outcomes of isolated infra-malleolar interventions for chronic limb-threatening ischemia.

Objective: Inframalleolar disease is present in most diabetic patients presenting with tissue loss. Inframalleolar (pedal) artery disease and pedal medial arterial calcification (pMAC) are associated with major amputation in patients with chronic limb-threatening ischemia (CLTI). This study aimed to examine the impact of pMAC on the outcomes after isolated inframalleolar (pedal artery) interventions.

Management of depth to achieve timely arteriovenous fistula utilization.

Objective: Failure to achieve timely arteriovenous fistulae (AVFs) utilization due to excessive depth (>6 mm) remains an ongoing concern for dialysis access. This study evaluates the outcomes of radiocephalic (RCF) and brachiocephalic (BCF) fistula elevation required for access utilization.

Methods: A retrospective review of all patients undergoing first-time autologous access over 10 years was undertaken.

Extracorporal Membrane Oxygenation in Massive Pulmonary Embolism.

Background: Massive pulmonary embolism (MPE) carries significant 30-day mortality risk, and a change in societal guidelines has promoted the increasing use of extracorporeal membrane oxygenation (ECMO) in the immediate management of MPE-associated cardiovascular shock. This narrative review examines the current status of ECMO in MPE.

Methods: A literature review was performed from 1982 to 2022 searching for the terms "Pulmonary embolism" and "ECMO," and the search was refined by examining those publications that covered MPE.

Endovascular management of acute and subacute venous thoracic outlet syndrome.

Approximately 3% of all patients presenting with Thoracic Outlet Syndrome have a venous etiology (vTOS), which is considered "effort thrombosis". These patients will present with symptomatic deep venous thrombosis or focal subclavian vein (SCV) stenosis. Endovascular management of vTOS occurs in several phases: diagnostic, preoperative therapeutic intervention before decompression, postoperative interventions after decompression, and delayed interventions in the follow-up after decompression.

Current status of ECMO for massive pulmonary embolism.

Massive pulmonary embolism (MPE) carries significant 30-day mortality and is characterized by acute right ventricular failure, hypotension, and hypoxia, leading to cardiovascular collapse and cardiac arrest. Given the continued high mortality associated with MPE, there has been ongoing interest in utilizing extracorporeal membrane oxygenation (ECMO) to provide oxygenation support to improve hypoxia and offload the right ventricular (RV) pressure in the belief that rapid reduction of hypoxia and RV pressure will improve outcomes. Two modalities can be employed: Veno-arterial-ECMO is a reliable process to decrease RV overload and improve RV function, thus allowing for hemodynamic stability and restoration of tissue oxygenation.

Development and Evaluation of an Enhanced Recovery Protocol to Reduce Length of Stay following Elective Endovascular Aneurysm Repair.

Background: Elective endovascular abdominal aortic aneurysm repair (EVAR) can be performed safely with a short postoperative length of stay (LOS). We aimed to develop and assess the impact of an enhanced recovery protocol (ERP) on LOS after elective EVAR.

Methods: Pre-ERP development single center retrospective review of elective EVAR procedures from January 2012 to December 2019.

Venous thoracic outlet syndrome and hemodialysis.

Central venous stenotic disease is reported in 7%-40% of patients needing a central venous catheter for dialysis and in 19%-41% of hemodialysis patients who have had a prior central venous catheter. Half of these patients will be asymptomatic. Venous Thoracic Outlet syndrome in hemodialysis (hdTOS) is part of this spectrum of disease.

Current status of pulmonary artery denervation.

Pulmonary hypertension is a progressive disease with a poor long-term prognosis and high mortality. Pulmonary artery denervation (PADN) is emerging as a potential novel therapy for this condition. The basis of pursuing a sympathetic denervation strategy has its origins in a body of experimental translation work that has demonstrated that denervation can reduce sympathetic nerve activity in various animal models.

Management of spontaneous dissection and rupture of common iliac artery in vascular Ehlers-Danlos syndrome (VEDS).

A 28-year-old male with history of vascular Ehlers-Danlos syndrome (VEDS) presented with left lower extremity acute limb ischemia. Computed tomography angiography demonstrated spontaneous dissection of the left common iliac artery with occlusion and associated contained rupture . Successful stent placement without associated complications was achieved with the following principles: (1) open arterial exposure for endovascular intervention; (2) no touch technique vessel dissection; (3) circumferential proximal arterial felt cuff reinforcement to reduce systolic pulse wave stretch on sutures, and in case of emergent ligation; and (4) pledgetted "preclose U" stitch monofilament suture prior to access.

A Single Center 8 Year Experience of Segmental Arterial Mediolysis Management.

Objective: Segmental Arterial Mediolysis (SAM) is a rare, poorly understood vasculopathy that involves vacuolization of the arterial wall, most commonly of the visceral arteries. There are no established therapeutic or monitoring guidelines for SAM, and intervention typically depends on patient presentation. The purpose of this study is to review the management and outcomes of patients with this rare vascular disease METHODS: Single center retrospective review of patients diagnosed with SAM between 2011 and 2019.

Efficacy of prophylactic inferior vena caval filters in prevention of pulmonary embolism in the absence of deep venous thrombosis.

There is an increasing use of inferior vena caval filters (IVCFs) as prophylactic activity in the absence of a deep venous thrombosis (DVT) to prevent pulmonary embolism (PE) in high-risk patients. These devices are effective in preventing PE in the presence of lower extremity DVT, when anticoagulation is contraindicated or has failed. An electronic databases search of MEDLINE, PubMed, The Cochrane Library, and Google Scholar for relevant articles listed between January 2000 and December 2014 was performed.
