Computed tomography scanning in the diagnosis of lower extremity phlebolymphedema.

Objectives: Phlebolymphedema, the most common cause of secondary lymphedema in Western societies, seldom gets the attention it deserves. Diagnosis is often missed and when evaluated is through lymphoscintigraphy (LSG) which is cumbersome. This study aims to assess the role of computed tomography (CT) scanning in the diagnosis of phlebolymphedema of the lower extremities by comparing CT characteristics to the International Society of Lymphology (ISL) grading system and LSG.

Nutcracker syndrome (a Delphi consensus).

Background: Nutcracker syndrome (NCS) describes the symptomatic compression of the left renal vein between the aorta and superior mesenteric artery. Whereas asymptomatic compression is a common radiological finding, patients with NCS can report a range of symptoms. There are no specific diagnostic criteria and interventions include a range of open surgical and endovascular procedures.

The impact of venous thromboembolism before open or minimally-invasive radical cystectomy in the USA: insurance claims data on perioperative outcomes and healthcare costs.

Background: The relationship between venous thromboembolism (VTE) and solid malignancy has been established over the decades. With rising projected rates of bladder cancer (BCa) worldwide as well as increasing number of patients experiencing BCa and VTE, our aim is to assess the impact of a preoperative VTE diagnosis on perioperative outcomes and health-care costs in BCa cases undergoing radical cystectomy (RC).

Methods: Patients ≥18 years of age with BCa diagnosis and undergoing open or minimally invasive (MIS) RC were identified in the Merative™ Marketscan Research Databases between 2007 and 2021.

Impact of native iliac vein aspect ratio on initial clinical presentation and outcomes following stenting for symptomatic chronic iliofemoral venous obstruction.

Objective: Venous stenting has become the first line of treatment for patients with symptomatic chronic iliofemoral venous obstruction (CIVO) in whom conservative therapy has failed. Intravascular ultrasound (IVUS) interrogation with the use of normal minimal luminal diameters or areas has become the standard to confirm the diagnosis and determine the adequacy of stenting. However, the aspect ratio (ratio between the maximal and minimal luminal diameters) has also been put forth as a possible metric for determining stent adequacy.

The Impact of Venous Thromboembolism on Upper Tract Urothelial Carcinomas Undergoing Open or Minimally Invasive Radical Nephroureterectomy in the USA: Perioperative Outcomes and Health Care Costs from Insurance Claims Data.

Background And Objective: Venous thromboembolism (VTE) is a significant predictor of worse postoperative morbidity in cancer surgeries. No data have been available for patients with preoperative VTE and upper tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU). Our aim was to assess the impact of a preoperative VTE diagnosis on perioperative outcomes in the RNU context.

Noninvasive measurement of ambulatory venous pressure via column interruption duration in chronic venous disease.

Background: Column interruption duration (CID) is a noninvasive surrogate for venous refill time (VFT), a parameter used in ambulatory venous pressure measurement. CID is more accurate than invasive VFT measurement because it avoids errors involved with indirect access of the deep system through the dorsal foot vein. The aim of this retrospective single center study is to analyze the clinical usefulness of CID in assessment of chronic venous disease (CVD).

Diagnosis of chronic iliac venous obstruction.

Stenting has become the first line of treatment for symptomatic chronic iliofemoral venous obstruction in patients with quality-of-life-impairing clinical manifestations who have failed conservative therapy. Patient selection for such intervention is, however, dependent on clear identification of relevant clinical manifestations and subsequent testing to confirm the diagnosis. In this regard, the physician engaged in management of such patients needs to be well-aware of symptoms and signs of chronic iliofemoral venous obstruction, and instruments used to grade chronic venous insufficiency and determine quality of life, in addition to diagnostic tests available and their individual roles.

Successful Wallstent exclusion of iliofemoral venous aneurysms-a new treatment paradigm.

Treatment of venous aneurysms involving the iliac and femoral veins has generally been an open surgical approach, with a few case reports noting use of an endovascular approach. We report three cases: (1) a patient with an iliocaval occlusion involving an occluded TrapEase filter who presented with a large left external iliac vein aneurysm; (2) a patient with a left common femoral vein aneurysm; and (3) a patient with left profunda femoris vein aneurysms with associated pulmonary embolism. All three patients were successfully managed with the use of appropriately sized bare metal woven stents (Wallstents; Boston Scientific).

The beneficial role of complex decongestive therapy in patients with symptomatic chronic iliofemoral venous obstruction with phlebolymphedema.

Objective: Phlebolymphedema has been noted to be one of the most common causes of lymphedema in the lower extremity in western societies. Although complex decongestive therapy (CDT) represents the mainstay of lymphedema treatment, its role for phlebolymphedema arising from chronic iliofemoral venous obstruction (CIVO) merits further exploration. We evaluated this through the use of a protocol of CDT first for limbs with CEAP (clinical, etiologic, anatomic, pathophysiologic) clinical C3 disease and stent correction of obstruction before CDT for those with more advanced disease (CEAP C4-C6).

The 2023 Society for Vascular Surgery, American Venous Forum, and American Vein and Lymphatic Society clinical practice guidelines for the management of varicose veins of the lower extremities. Part II: Endorsed by the Society of Interventional Radiology and the Society for Vascular Medicine.

The Society for Vascular Surgery, the American Venous Forum, and the American Vein and Lymphatic Society recently published Part I of the 2022 clinical practice guidelines on varicose veins. Recommendations were based on the latest scientific evidence researched following an independent systematic review and meta-analysis of five critical issues affecting the management of patients with lower extremity varicose veins, using the patients, interventions, comparators, and outcome system to answer critical questions. Part I discussed the role of duplex ultrasound scanning in the evaluation of varicose veins and treatment of superficial truncal reflux.

Inguinal intranodal lymphangiography reveals a high incidence of suprainguinal lymphatic disease in patients with leg edema undergoing stenting for symptomatic chronic iliofemoral venous obstruction.

Objective: Recent studies have emphasized the important role lymphatics play in the drainage of interstitial fluid and edema prevention. Although the infrainguinal lymphatics have been studied in some depth, with patterns of pathology identified, such data above the groin are sparse, especially for patients with phlebolymphedema. The present study attempts to evaluate the status of lymphatic flow above the inguinal ligament in patients presenting with edema and undergoing stenting for symptomatic chronic iliofemoral venous obstruction (CIVO).

An Overview of Specific Considerations in Chronic Venous Disease and Iliofemoral Venous Stenting.

Unlike arterial disease, chronic venous disease (CVD) is rarely life-threatening or limb-threatening. However, it can impose substantial morbidity on patients by influencing their lifestyle and quality of life (QoL). The aim of this nonsystematic narrative review is to provide an overview of the most recent information on the management of CVD and specifically, iliofemoral venous stenting in the context of personalized considerations for specific patient populations.

Technique of stent sizing in patients with symptomatic chronic iliofemoral venous obstruction-the case for intravascular ultrasound-determined inflow channel luminal area-based stenting and associated long-term outcomes.

Objective: Femoroiliocaval stenting has become the standard of care for patients with quality-of-life impairing chronic iliofemoral venous obstruction not responding to conservative measures. Although improvement after stenting has been noted in multiple large studies, sizing of stents has been subjective in nature with a general tendency to use smaller stents that would be required to relieve venous hypertension. This study evaluates the authors' technique of using the intravascular ultrasound (IVUS) inflow channel luminal area to guide stent sizing.
