Monocentric prospective study to valid multidisciplinary diagnostic and therapeutic approach for Nutcracker syndrome.

Nutcracker syndrome (NCS) is defined as left renal vein (LRV) compression by the superior mesenteric artery. NCS diagnosis is rendered complex by confounding symptoms. The study objective was to perform a prospective observational analysis of the diagnostic and therapeutic criteria of the patients with suspected NCS.

Midterm and Long-Term Outcomes following Dedicated Endovenous Nitinol Stent Placement for Symptomatic Iliofemoral Venous Obstruction: Three- to 5-Year Results of the VIRTUS Study.

Purpose: To assess the midterm patency and long-term safety of placement of a dedicated venous stent (Vici Venous Stent System) for the treatment of venous lesions of the iliofemoral outflow tract.

Materials And Methods: Patients with unilateral obstructive disease of the iliofemoral veins and a Clinical, Etiological, Anatomical, Pathophysiological class of 3 or higher or a Venous Clinical Severity Score of 2 or greater were enrolled in this prospective, multicenter, single-arm study at 23 sites in the United States and Europe. The patients were followed up for 36 months after the index procedure for the assessment of patency and up to 60 months for the assessment of safety.

The Symptoms-Varices-Pathophysiology classification of pelvic venous disorders: A report of the American Vein & Lymphatic Society International Working Group on Pelvic Venous Disorders.

As the importance of pelvic venous disorders (PeVD) has been increasingly recognized, progress in the field has been limited by the lack of a valid and reliable classification instrument. Misleading historical nomenclature, such as the May-Thurner, pelvic congestion, and nutcracker syndromes, often fails to recognize the interrelationship of many pelvic symptoms and their underlying pathophysiology. Based on a perceived need, the American Vein and Lymphatic Society convened an international, multidisciplinary panel charged with the development of a discriminative classification instrument for PeVD.

Endovascular Treatment for Venous Diseases: Where are the Venous Stents?

There is a growing need for dedicated endovascular devices to treat pathologies affecting the venous system. However, because of a lack of research into venous diseases and treatments, the optimal design, material, and mechanical properties of venous stents remain unknown. Development of the ideal venous stent should be based on a thorough understanding of the underlying venous pathology.

Associated Da Vinci and magellan robotic systems for successful treatment of nutcracker syndrome.

Here, we report the case of a 26-year-old woman suffering from nutcracker syndrome with concurrent disabling pelvic congestion syndrome. She was given the minimally invasive treatment of left renal vein transposition with the Da Vinci(®) robotic system (Intuitive Surgical, Sunnyvale, CA), followed the next day by a gonadal vein and pelvic varicose embolization using a robotic intraluminal navigation with the Magellan™ robotic system (Hansen Medical, Mountain View, CA). The procedure was uneventful, and the patient had good results at 6 months of follow-up, including a patent left renal vein and complete relief of symptoms.

Staged procedure to prevent major adverse events in extensive aortic aneurysm repair.

Surgical management of extensive thoracoabdominal aortic aneurysms is associated with high rates of mortality and morbidity, including spinal cord ischemia. We report a successful three-stage repair combining open and endovascular surgery in a patient presenting with an ascending, arch, and thoracoabdominal aneurysm. Spinal cord protective measures included a staged approach, preserved antegrade flow to the left subclavian and hypogastric arteries, absence of aortic cross-clamping, and aggressive perioperative hemodynamic monitoring.
