Venous stenting versus venous ablation.

Background: The minimally invasive procedures of venous ablation and iliac vein stenting are evolving treatment options for venous insufficiency. Yet, there are no studies directly comparing the outcome of these procedures. We performed a survey on patients who had both procedures, to determine if either procedure helped more and if there is any other clinical factor related to the outcome.

Transcarotid Artery Revascularization for Symptomatic Retropharyngeal Internal Carotid Artery Stenosis.

Retropharyngeal internal carotid artery (ICA) is a rare, yet well-described anatomical variant that poses significant challenges to the management of carotid artery stenosis. In this case report, we discuss the treatment of symptomatic ICA stenosis with a retropharyngeal ICA using the transcarotid artery revascularization (TCAR) technique. A 70-year-old female with comorbidities presented with neurological symptoms and severe ICA stenosis.

Expansion of WallStents® after Initial Deployment in Nonthrombotic Iliac Vein Lesions.

Background: To determine the structural changes of Wallstents (Boston Scientific, Natick, MA) in vivo following deployment in iliac veins.

Methods: This retrospective single-center study was performed from September 2012 to April 2013 and included 100 office-based patients who underwent initial stent placement for nonthrombotic iliac vein lesions with Wallstent as well as a second procedure for stenting of the contralateral iliac vein. Measurements were obtained with marker balloons and the diameters of the stents were compared at the time of the index procedure to the secondary procedure.

Factors associated with recanalization and reintervention following below knee polidocanol endovenous microfoam ablation for great saphenous and small saphenous veins.

Background: Polidocanol endovenous microfoam (PEM) has been used to treat lower extremity venous reflux for almost one decade with specific advantages for below knee (BK) truncal veins where thermal ablation poses a risk of injury to adjacent nerves. The current literature of the BK segment often examines short-term outcomes with modest sample sizes. We aim to identify factors associated with recanalization and reintervention in this subset of patients.

Impact of the endovascular revolution on vascular training through analysis of national data case reports.

Background: In the last couple of decades, there has been a shift in use of endovascular procedures in vascular surgery. We aim to examine the impact of this endovascular shift on vascular trainees, determine whether the surgical experiences of trainees in the integrated residency and fellowship program changed over time, and identify differences between the two training paradigms.

Methods: Data were extracted from the Accreditation Council for Graduate Medical Education National Data Case Logs for the vascular surgery fellowship (1999-2021) and integrated residency (2012-2021) programs.

Risk factors for low back pain after iliac vein stenting for non-thrombotic iliac vein lesions.

Objective: Iliac vein stenting is an option being explored to treat chronic venous insufficiency. We have noted that our most common postoperative complication is low back pain after stent placement, which is occasionally quite severe. We wanted to investigate risk factors that are involved in this phenomenon and identify potentially modifiable factors.

Value and limitations of postoperative duplex scans after endovenous thermal ablation.

Background: Endovenous thermal ablation (EVTA) of the lower extremity veins has risen to become the main treatment modality for symptomatic venous reflux disease. One of the main reported side effects of EVTA is recanalization. As of today, there is no clear protocol as to when follow-up duplex ultrasound scans should be performed.

Who are the Vascular Society Presidents?

Background: We noted distinct differences between the demographics among the presidents of various vascular societies. To help characterize these among the present United States, Canadian, and European vascular societies, we queried the websites for the United States, Canadian, and European vascular societies in a systematic review for the names of their presidents since their respective inceptions.

Methods: Age and ethnicity were determined by a search on healthgrades.

Seasonal variation in swelling of lower extremity edema in patients with chronic venous insufficiency.

Objective: We had observed that some patients with chronic venous insufficiency (CVI) had reported their lower extremity edema was worse during warmer weather. Limited research is available regarding the seasonal variation in lower extremity edema. Patients with CVI were questioned to determine whether they had experienced significant seasonal variation in their lower extremity edema and which factors might be associated with such variation.

Early Results With a New Endovenous Radiofrequency Ablation Catheter, Venclose®.

Objectives: Endovenous Radio-frequency Ablation (RFA) has become a common treatment for chronic venous insufficiency. The Medtronic Closurefast catheter was previously the only RFA catheter approved for use in this procedure. In 2018 VenClose Company's new device was approved.

Comparison of Recent Practice Guidelines for the Management of Patients With Asymptomatic Carotid Stenosis.

Despite the publication of several national/international guidelines, the optimal management of patients with asymptomatic carotid stenosis (AsxCS) remains controversial. This article compares 3 recently released guidelines (the 2020 German-Austrian, the 2021 European Stroke Organization [ESO], and the 2021 Society for Vascular Surgery [SVS] guidelines) vs the 2017 European Society for Vascular Surgery (ESVS) guidelines regarding the optimal management of AsxCS patients.The 2017 ESVS guidelines defined specific imaging/clinical parameters that may identify patient subgroups at high future stroke risk and recommended that carotid endarterectomy (CEA) should or carotid artery stenting (CAS) may be considered for these individuals.

Adjunctive topical oxygen therapy for wound healing in patients with peripheral arterial disease.

Introduction: While the use of hyperbaric oxygen therapy has been supported by randomized prospective trials for the use of selective lower extremity wounds, it is associated with significant cost, inconvenience, and a small risk of pneumothorax, barotrauma to the tympanic membrane, and severe hypoglycemia. As topical oxygen therapy (tOT) avoids these issues and there is little literature examining its use for patients with peripheral arterial disease (PAD), we reviewed our experience with tOT as an adjunctive technique for wound healing with arterial wounds.

Methods: We reviewed our experience with tOT for lower extremity wounds over 8 years.

Success rate and factors predictive of redo endothermal ablation of small saphenous veins.

Objective: Endothermal ablation, such as endovenous laser ablation (EVLA) and radiofrequency ablation (RFA), has been increasingly used for treatment of small saphenous vein (SSV) insufficiency. Prior studies have shown recurrence rates of 0% to 10% in incompetent SSVs (ISSVs). The objective of the present study was to determine the efficacy of redo venous ablation for symptomatic recanalized SSVs and to predict the factors related to recanalization.

The Great Masquerader - TB Osteoarthritis.

Objectives: TB arthritis is a rarely reported entity in Western literature and its ability to masquerade as many other diseases makes it difficult to diagnose. We report an interesting case of TB arthritis of the ankle.

Methods: We present a 44 year-old diabetic Chinese male with a recent history of worsening pain, swelling, and redness in his left foot with an abscess and X-ray findings consistent with Charcot foot.

Correlation of body mass index with recanalization risk after endovenous thermal ablation.

Objective: Chronic venous insufficiency (CVI) has an increased prevalence among obese individuals with body mass indices (BMI) over 30. A safe, efficacious, and evidence-based recommended treatment for CVI due to superficial venous reflux (SVR) in great saphenous veins (GSVs), small saphenous veins (SSVs), accessory saphenous veins (ASVs), and reflux in the perforator veins (PVs) is endovenous thermal ablation (EVTA). We sought to identify if BMI is an independent risk factor for recanalization after EVTA.

Case report of superficial femoral artery and popliteal artery aneurysm repair using brachial vein.

Background: Several veins have been well-recognized as acceptable conduits for infrainguinal bypass surgery when the ipsilateral greater saphenous vein is unavailable. However, there is a paucity of literature describing the brachial vein as an adequate alternative. In the absence of other viable autogenous conduits, we describe the use of a brachial vein as a successful alternative for lower extremity revascularization.

Sphygmomanometer-induced hemostasis following iatrogenic guidewire perforation during lower extremity angioplasty.

Objectives: Iatrogenic guidewire perforation is a well-known complication of lower extremity angioplasty that is often benign or can be easily treated with endovascular techniques. However, perforations that occur in arterial side branches may be more challenging to manage. If bleeding persists, open surgery and fasciotomy may be required to evacuate the resulting hematoma and prevent compartment syndrome.
