Paradigm Shifts in Vascular Surgery: Analysis of the Top 100 Innovative and Disruptive Academic Publications.

Background: Disruption score (DS) is a novel bibliometric created to identify research that shifts paradigms, which may be overlooked by citation count (CC). We analyzed the most disruptive, compared to the most cited, literature in vascular surgery, and hypothesized that DS and CC would not correlate.

Methods: A PubMed search identified vascular surgery publications from 1954 to 2014.

Overcoming Barriers: Sex Disparity in Surgeon Ergonomics.

Background: Musculoskeletal discomfort is widely experienced by surgeons across multiple surgical specialties. Developing technologies and new minimally invasive techniques add further complexity and ergonomic stressors. These stressors differentially affect male and female surgeons, but little is known about the role these sex disparities play in surgical ergonomic stress.

Epidemiology, repair technique, and predictors of stroke and mortality in penetrating carotid artery injuries.

Objective: Penetrating carotid artery injuries (PCAI) are significantly morbid and deadly, often presenting in extremis with associated injuries and central nervous system deficit. Repair may be challenging with arterial reconstruction vs ligation role poorly defined. This study evaluated contemporary outcomes and management of PCAI.

International Multi-Institutional Experience with Presentation and Management of Aortic Arch Laterality in Aberrant Subclavian Artery and Kommerell's Diverticulum.

Background: Aberrant subclavian artery (ASA) with or without Kommerell's diverticulum (KD) is a rare anatomic aortic arch anomaly that can cause dysphagia and/or life-threatening rupture. The objective of this study is to compare outcomes of ASA/KD repair in patients with a left versus right aortic arch.

Methods: Using the Vascular Low Frequency Disease Consortium methodology, a retrospective review was performed of patients ≥18 years old with surgical treatment of ASA/KD from 2000 to 2020 at 20 institutions.

Contemporary outcomes after treatment of aberrant subclavian artery and Kommerell's diverticulum.

Objective: Aberrant subclavian artery (ASA) and Kommerell's diverticulum (KD) are rare vascular anomalies that may be associated with lifestyle-limiting and life-threatening complications. The aim of this study is to report contemporary outcomes after invasive treatment of ASA/KD using a large international dataset.

Methods: Patients who underwent treatment for ASA/KD (2000-2020) were identified through the Vascular Low Frequency Disease Consortium, a multi-institutional collaboration to investigate uncommon vascular disorders.

Functional performance status and risk of cardiovascular events and mortality following endovascular repair of thoracic and abdominal aortic pathology.

Objective: To characterize the association of preoperative functional performance status based on Eastern Cooperative Oncology Group (ECOG) scoring with the risk of adverse cardiovascular events, vascular events, and mortality in patients undergoing EVAR and TEVAR.

Methods: Retrospective review of the Society for Vascular Surgery Vascular Quality Initiative, a large, multi-center, registry database was performed. All individuals undergoing EVAR ( = 18,730) and TEVAR ( = 6595) for non-ruptured aortic pathologies between 2014 and 2018 were eligible for analysis.

Risk of renal failure and death when renal arteries are involved in endovascular aortic aneurysm repair.

Objective: Endovascular abdominal aortic repair can involve the incorporation of renal arteries. Revascularization after intentional or unintentional renal artery (RA) coverage is not always technically successful, and the loss of a single RA may result in the need for postoperative dialysis. Thus, we compared the outcomes after endovascular aneurysm repair (EVAR) stratified by RA involvement (RAI).

Complications associated with lumbar drain placement for endovascular aortic repair.

Objective: We reviewed the complications associated with perioperative lumbar drain (LD) placement for endovascular aortic repair.

Methods: Patients who had undergone perioperative LD placement for endovascular repair of thoracic and thoracoabdominal aortic pathologies from 2010 to 2019 were reviewed. The primary endpoints were major and minor LD-associated complications.

Branch Vessel Patency after Thoracic Endovascular Aortic Repair for Type B Aortic Dissection.

Background: Thoracic endovascular aortic repair (TEVAR) for type B aortic dissections is used to promote false lumen (FL) thrombosis and favorable aortic remodeling, but its impact on occlusion of FL origin branch vessels has not been widely described. We compare FL versus true lumen (TL) branch vessel patency after TEVAR.

Methods: Patients treated by TEVAR for type B aortic dissection in zones 2-5 in the Vascular Quality Initiative from 2009 to 2018 were evaluated.

Association of upper extremity and neck access with stroke in endovascular aortic repair.

Objective: Upper extremity and neck access is commonly used for complex endovascular aortic repairs. We sought to compare perioperative stroke and other complications of (1) arm/neck (AN) and femoral or iliac access versus femoral/iliac (FI) access alone, (2) right- versus left-sided AN, and (3) specific arm versus neck access sites.

Methods: Patients entered in the thoracic endovascular aortic repair/complex endovascular aortic repair registry in the Vascular Quality Initiative from 2009 to 2018 were analyzed.

Functional ambulatory status as a potential adjunctive decision-making tool following wound, level of ischemia, and severity of foot infection assessment.

The Society for Vascular Surgery Lower Extremity Threatened Limb Classification System has been developed to stratify amputation risk on the basis of extent of the wound, level of ischemia, and severity of foot infection (WIfI). However, there are no currently validated metrics to assess, grade, and consider functional status, especially ambulatory status, as a major consideration during limb salvage efforts. Therefore, we propose an adjunct to the current WIfI system to include the patient's ambulatory functional status after initial assessment of limb threat.

Association of aberrant subclavian arteries with aortic pathology and proposed classification system.

Objective: Aberrant subclavian artery (aSCA) is a rare anatomic variant whose association with other aortic branch variations and aortic pathology has yet to be established. Knowledge of such an association could be relevant to recommendations for screening and awareness as associated variations are important for operative planning. We describe the incidence of aSCA variations, its association with aortic pathology, and a proposed classification system.

A standardized trauma-specific endovascular inventory.

We believe that the rapid and widespread adoption of resuscitative endovascular balloon occlusion of the aorta as well as enthusiasm for catheter-based strategies has led to increased interest in basic endovascular techniques among trauma surgeons. The aim of this article was to describe the most commonly performed endovascular procedures for trauma patients, the basic capital equipment and room set up, and a parsimonious inventory of disposable supplies needed to perform each procedure. Together, these make a standardized trauma-specific endovascular inventory.

Impact of ligation versus repair of isolated popliteal vein injuries on in-hospital outcomes in trauma patients.

Background: Popliteal vascular injuries are common and frequently associated with limb loss. Although many studies have evaluated the treatment and outcomes of popliteal artery injuries (PAI), there is little available evidence regarding popliteal venous injuries (PVI). As such, substantial debate remains regarding the benefit of repair over ligation of PVI.

Methicillin-resistant Staphylococcus aureus portends a poor prognosis after endovascular repair of mycotic aortic aneurysms and aortic graft infections.

Objective: Mycotic aortic aneurysms and aortic graft infections (aortic infections [AIs]) are rare but highly morbid conditions. Open surgical repair is the "gold standard" treatment, but endovascular repair (EVR) is increasingly being used in the management of AI because of the lower operative morbidity. Multiple organisms are associated with AI, and bacteriology may be an important indication of mortality.

Endovascular septal fenestration using a radiofrequency wire to salvage inadvertent false lumen deployment of a frozen elephant trunk stent graft.

We report a case of a frozen elephant trunk arch repair, where the stent graft was unintentionally placed into the false lumen. Postoperative imaging demonstrated an enlarged false lumen with no thoracic aorta fenestrations that could be traversed to place another thoracic endovascular aortic repair endograft into the true lumen. An atraumatic radiofrequency wire (PowerWire, Baylis Medical, Montreal, Quebec, Canada) was used to create a new septal fenestration, enabling thoracic endovascular aortic repair endograft extension into the thoracic true lumen.

Hydroxyapatite-binding micelles for the detection of vascular calcification in atherosclerosis.

Atherosclerosis is a chronic disease characterized by the formation of calcified, arterial plaques. Microcalcifications (5 μm to 100 μm), mainly composed of hydroxyapatite (HA, Ca(PO)(OH)), develop in the fibrous caps of atherosclerotic plaques and can trigger plaque rupture due to the loss of compliance and elasticity. Ultimately, plaque rupture can cause arterial occlusion and embolization and result in ischemic events such as strokes and myocardial infarctions.

Impact of inferior vena cava ligation on mortality in trauma patients.

Objective: Inferior vena cava (IVC) injuries are potentially lethal and require prompt intervention. Repair of complex IVC injuries may require the use of a prosthetic graft or a complicated panel or spiral vein graft reconstruction to avoid the need for ligation. Collateral venous drainage may be sufficient to allow acceptable results from IVC ligation; however, previous studies have suffered from low numbers and have differing results.

Fourth Time Redo Common Femoral Vein Reconstruction with a Novel Hybrid Technique.

Background: Iliofemoral vein thrombosis can lead to debilitating edema and venous claudication that significantly worsens quality of life, especially in young active individuals. Venous reconstruction becomes increasingly complex and has worsening patency with subsequent revisions so preoperative planning is critical to success.

Methods: We report a case of a 54-year-old man in active military service with profoundly symptomatic leg swelling after failure of 3 previous common femoral vein (CFV) reconstructions.

Inferior Vena Cava Filter Resulting in Perforation and Massive Retroperitoneal Hematoma Presenting as Acute Onset of Lower Extremity Weakness.

Perforation of inferior vena cava (IVC) filter struts is a common incidental finding on postoperative computed tomography (CT) scans that is not associated with bleeding or major complications. However, in rare circumstances, it can be associated with hemorrhage requiring immediate removal. We present a case of a 62-year-old man who developed abdominal pain and right lower extremity weakness 2 weeks after treatment of a pulmonary embolism with IVC filter placement and anticoagulation.

Carotid Artery Entrapment by the Hyoid Bone-A Rare Cause of Recurrent Strokes in a Young Patient.

The search for etiology of stroke in a young patient may present a diagnostic challenge. In rare cases, chronic trauma to the carotid artery may be the cause of cerebral thromboembolic events. The hyoid bone lies in close proximity to the carotid artery bifurcation, and anatomic variants have been implicated in carotid compression, stenosis, dissection, and pseudoaneurysm.

Successful use of continuous vasodilator infusion to treat critical vasospasm threatening a distal bypass.

Vasospasm immediately after lower extremity arterial bypass may represent an uncommon cause of early graft failure. We report a successful case of catheter-directed, intra-arterial continuous vasodilator infusion to salvage a bypass graft threatened by severe, refractory vasospasm after incomplete response to nicardipine, verapamil, and nitroglycerin boluses. A continuous nitroglycerin infusion was administered for 24 hours, by which time the vasospasm resolved.
