Vascular Surgeon Involvement in Pulmonary Embolism Response Teams: Barriers, Challenges, Concerns and the Imperative for Integration.

Background: The effective management of pulmonary embolism (PE) necessitates coordinated care among physicians from diverse specialties within a time-sensitive framework. Pulmonary Embolism Response Teams (PERTs) have been developed as a strategic approach to optimize and expedite treatment by integrating and coordinating different specialties. The current survey audit aimed to understand the level of interest among vascular surgeons and the logistical considerations surrounding their participation within the PERT.

Multi-center experience with intravascular lithotripsy for treatment of severe calcification during transcarotid artery revascularization for high-risk patients.

Objective: Transcarotid artery revascularization (TCAR) offers a safe alternative to carotid endarterectomy (CEA), but severe calcification is currently considered a contraindication in carotid artery stenting. This study aims to describe the safety and effectiveness of TCAR with intravascular lithotripsy (IVL) in patients with traditionally prohibitive calcific disease.

Methods: All consecutive patients who underwent TCAR+IVL from 2018-2022 at nine institutions were identified.

Catheter Interventions for Pulmonary Embolism: Mechanical Thrombectomy Versus Thrombolytics.

Pulmonary embolism is a debilitating and potentially life-threatening disease characterized by high mortality and long-term adverse outcomes. Traditional treatment options are fraught with serious bleeding risks and incomplete thrombus removal, necessitating the development of innovative treatment strategies. While new interventional approaches offer promising potential for improved outcomes with fewer serious complications, their rapid development and need for more comparative clinical evidence makes it challenging for physicians to select the optimal treatment for each patient among the many options.

A referral pathway for treating patients with severe venous disease using mechanical thrombectomy.

Background: DVT is associated with clinically significant sequelae, and the most widely used therapies for severe venous disease are often ineffective. Mechanical thrombectomy (MT) offers a promising approach, but most patients with a history of DVT are not evaluated for such intervention.

Objective: To present overall outcomes and the outcome of a single case after use of an MT procedure to manage advanced deep venous disease.

Complicated and Uncomplicated Isolated Abdominal Aortic Dissections Demonstrate Different Patient Characteristics and Outcomes.

Background: Isolated abdominal aortic dissection (IAAD) is a rare entity with poorly defined risk factors and wide variation in management. We set forth to compare patient characteristics, management, and outcomes of uncomplicated isolated abdominal aortic dissection (uIAAD) versus high risk and complicated isolated abdominal aortic dissection (hrcIAAD) to investigate whether these categories can be utilized to guide IAAD management and provide risk stratification for intervention.

Methods: Retrospective chart review was performed to identify all patients with spontaneous IAAD at a tertiary health care system between 1996 and 2022.

Impact of COVID-19 on patients undergoing scheduled procedures for chronic venous disease.

Objective: The COVID-19 pandemic has drastically altered the medical landscape. Various strategies have been employed to preserve hospital beds, personal protective equipment, and other resources to accommodate the surges of COVID-19 positive patients, hospital overcapacities, and staffing shortages. This has had a dramatic effect on vascular surgical practice.

Comparison of anticoagulation vs mechanical thrombectomy for the treatment of iliofemoral deep vein thrombosis.

Objective: To compare the comparative effects of treatment with contemporary mechanical thrombectomy (MT) or anticoagulation (AC) on Villalta scores and post-thrombotic syndrome (PTS) incidence through 12 months in iliofemoral deep vein thrombosis (DVT).

Methods: Patients with DVT in the Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis (ATTRACT) randomized trial and the ClotTriever Outcomes (CLOUT) registry were included in this analysis. Both studies evaluated the effects of thrombus removal on the incidence of PTS.

Ultrasound-Guided Mechanical Thrombectomy Without Radiation for Deep Vein Thrombosis in Early Pregnancy.

The cases presented herein describe the interventional treatment of deep vein thrombosis and related clinical considerations for 2 young patients in early pregnancy. Treatment decisions made collaboratively with obstetricians aimed to prioritize the safety of the mother and fetus and were primarily informed by the patients' clinical and social status.

Mechanical Thrombectomy vs. Pharmacomechanical Catheter Directed Thrombolysis for the Treatment of Iliofemoral Deep Vein Thrombosis: A Propensity Score Matched Exploratory Analysis of 12 Month Clinical Outcomes.

Objective: To compare thrombus removal and residual venous symptoms and signs of disease following interventional treatment of iliofemoral deep vein thrombosis (DVT) with mechanical thrombectomy (MT) and pharmacomechanical catheter directed thrombolysis (PCDT).

Methods: Retrospective cohort analysis of propensity score matched subgroups from the multicentre prospective MT ClotTriever Outcomes registry and the PCDT arm of the randomised Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter Directed Thrombolysis trial. Patients with bilateral DVT, symptom duration greater than four weeks, isolated femoral-popliteal disease, or incomplete case data were excluded.

Effect of junctional reflux on the venous clinical severity score in patients with insufficiency of the great saphenous vein (JURY study).

Objective: Effective treatment options are available for chronic venous insufficiency associated with superficial venous reflux. Although many patients with C2 and C3 disease based on the CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification have combined great saphenous vein (GSV) and saphenofemoral junction (SFJ) reflux, some may not have concomitant SFJ reflux. Several payors have determined that symptom severity in patients without SFJ reflux does not warrant treatment.

Six-Month Outcomes of Mechanical Thrombectomy for Treating Deep Vein Thrombosis: Analysis from the 500-Patient CLOUT Registry.

Purpose: Mechanical thrombectomy for the treatment of deep vein thrombosis (DVT) is being increasingly utilized to reduce symptoms and prevent postthrombotic syndrome (PTS), but more data on clinical outcomes are needed. Mechanical thrombectomy was studied in the ClotTriever Outcomes (CLOUT) registry with 6-month full analysis outcomes reported herein.

Materials And Methods: The CLOUT registry is a prospective, all-comer study that enrolled 500 lower extremity DVT patients across 43 US sites treated with mechanical thrombectomy using the ClotTriever System.

Carotid Artery Operation Delay During the Covid-19 Pandemic: Results of a Multicenter International Study.

Background: To measure the impact of the COVID-19 pandemic on the management of patients with carotid artery stenosis.

Methods: We prospectively collected data from 25 centers (19 centers in the United States and 6 centers internationally) on postponed carotid artery operations between March 2020 and January 2022. We describe the characteristics of these patients and their planned operations, along with outcomes including mortality and neurological deterioration during the period of operative delay due to the COVID-19 pandemic.

Percutaneous mechanical thrombectomy to remove post-thrombotic obstructions and manage post-thrombotic syndrome-associated venous leg ulceration.

Background: Up to one half of patients with a diagnosis of deep vein thrombosis will develop post-thrombotic syndrome (PTS). Patients with PTS can develop venous leg ulcers (VLUs) due to post-thrombotic obstructions (PTOs) that contribute to prolonged ambulatory venous hypertension. The current treatments for PTS, which include chronic thrombus, synechiae, trabeculations, and inflow lesions, do not target PTOs, and such obstructions can affect stenting success.

Safety and Effectiveness of Mechanical Thrombectomy From the Fully Enrolled Multicenter, Prospective CLOUT Registry.

Background: We report in-hospital outcomes from the multicenter, prospective, single-arm ClotTriever Outcomes (CLOUT) registry, which enrolled up to 500 patients with proximal lower extremity deep vein thrombosis (DVT) treated with percutaneous mechanical thrombectomy using the ClotTriever System (Inari Medical).

Methods: The CLOUT registry enrolled all-comer patients with DVT, irrespective of symptom duration, thrombus age, prior treatment of the current DVT, or bilateral thrombus. The primary effectiveness end point was defined as complete or near complete (≥75%) reduction in Marder score.

Identifying potentially avoidable femoral to popliteal expanded polytetrafluoroethylene bypass for claudication using cross-site blinded peer review.

Objective: The surgical treatment of claudication can be associated with significant morbidity and costs. There are growing concerns that some patients proceed to interventions without first attempting evidence-based nonoperative management. We used a direct, cross-site, blinded expert review to evaluate the appropriateness of the surgical treatment of claudication.

Chronic venous ulcer resolution and post-thrombotic syndrome improvement after percutaneous mechanical thrombectomy of a 42-year-old deep vein thrombosis.

Post-thrombotic syndrome (PTS) is a chronic disease affecting up to one half of patients with deep vein thrombosis. PTS symptoms range in severity, with the worst form involving the development of venous ulcers. In the present report, we have described a patient with PTS with ulceration for >40 years.

Diversity efforts in surgery: Are we there yet?

Introduction: We aimed to assess and quantify recent efforts of surgical departments in achieving diversity, equity and inclusion.

Methods: Chairs of surgery at US hospitals were identified from a database maintained by the Association of Women Surgeons and surveyed to assess diversity, equity and inclusion efforts.

Results: A total of 226 surveys were sent out with a 22.

Society for Vascular Surgery best practice recommendations for use of social media.

The use of social media (SoMe) in medicine has demonstrated the ability to advance networking among clinicians and other healthcare staff, disseminate research, increase access to up-to-date information, and inform and engage medical trainees and the public at-large. With increasing SoMe use by vascular surgeons and other vascular specialists, it is important to uphold core tenets of our commitment to our patients by protecting their privacy, encouraging appropriate consent and use of any patient-related imagery, and disclosing relevant conflicts of interest. Additionally, we recognize the potential for negative interactions online regarding differing opinions on optimal treatment options for patients.

The impact of the COVID-19 pandemic on vascular surgery: Health care systems, economic, and clinical implications.

The novel severe acute respiratory syndrome coronavirus-2 (coronavirus disease 2019 [COVID-19]) pandemic is responsible for more than 500,000 deaths in the United States and nearly 3 million worldwide, profoundly altering the landscape of health care delivery. Aggressive public health measures were instituted and hospital efforts became directed at COVID-19-related concerns. Consequently, routine surgical practice was virtually halted, resulting in billions of dollars in hospital losses as pandemic costs escalated.

Mechanical thrombectomy of symptomatic carotid stenosis with free-floating thrombus in a patient with COVID-19 using transcarotid artery revascularization.

Carotid stenosis with free-floating thrombus is associated with ipsilateral neurologic deficits as a result of cerebrovascular accident or ischemic stroke. Arterial thrombosis and thrombus instability have shown an association with coronavirus disease 2019. Immediate evaluation is essential to assess and prevent thrombus propagation.

A statewide quality improvement collaborative significantly improves quality metric adherence and physician engagement in vascular surgery.

Background: Quality improvement national registries provide structured, clinically relevant outcome and process-of-care data to practitioners-with regional meetings to disseminate best practices. However, whether a quality improvement collaborative affects processes of care is less clear. We examined the effects of a statewide hospital collaborative on the adherence rates to best practice guidelines in vascular surgery.
