Practitioners of endovascular surgery have historically utilized two-dimensional (2D) intraoperative fluoroscopic imaging, with intra-vascular contrast opacification, to treat complex three-dimensional (3D) pathology. Recently, major technical developments in intraoperative imaging have made image fusion techniques possible: the creation of a 3D patient-specific vascular roadmap based on preoperative imaging which aligns with intraoperative fluoroscopy, with many potential benefits. First, a 3D model is segmented from preoperative imaging, typically a CT scan...

BACKGROUND: To date , thoracic endovascular aortic repair (TEVAR) for type B aortic dissection is favorable, but TEVAR for type B IMH remains uncertain. There are numerous clinical (eg, refractory pain) and radiologic (eg, IMH thickness) factors that are reported to be associated with IMH progression, challenging the treatment for high-risk type B IMH with high risk factors in clinical practice. OBJECTIVE: To perform a systematic review of clinical studies to investigate outcomes of TEVAR+BMT and BMT in the treatment of high-risk type B IMH ...

BACKGROUND/OBJECTIVE: Advancements in open and endovascular techniques have brought a widespread indication of revascularization in the majority of patients with critical limb ischemia (CLI). However, some cases still have a dismal short-term outcome. Identifying preoperative variables that characterize these patients could be important to prevent futile decisions. The aim of this study was to define predictive risk factors of mortality and/or major amputation after revascularization for CLI...

Chronic aortic dissecting aneurysms (TAAD) presenting after acute Stanford Type A or B dissection includes both arch and/or thoracoabdominal aortic aneurysms (TAAA). Approximately 60% of patients who survive surgical treatment of acute Type A aortic dissections will require another aortic procedure. Similarly, more than 70% of patients with chronic Type B aortic dissections will experience false lumen dilation at 5-year follow-up, often requiring intervention. Open or hybrid aortic repairs of complex TAAD involving the arch and the TAAA are very demanding procedures for both patients and clinicians...

Thromboses of the superior and inferior vena cava, either isolated or associated with distal deep venous thrombosis, are uncommon, but confer potentially serious morbidity and mortality. Incidence is increasing, especially with the prominence of intravascular devices. The range of treatment options is also expanding to include medical management, surgery, and endovascular techniques which are now frequently considered first line therapy due to lower reintervention rates and decreased periprocedural morbidity...

Endovascular techniques have revolutionized the management of deep venous occlusive disease. Open surgery, however, is still required for cases that prove refractory to endovascular interventions. The surgical management of deep venous occlusive disease typically involves venous bypass. Preoperative planning before open venous surgery relies upon dynamic imaging to clarify the location and severity of venous obstruction, the assessment of infrainguinal reflux, and the delineation of bypass origination and target vessels...

May-Thurner syndrome (MTS) is a rare condition in which patients develop iliofemoral deep venous thrombosis owing to an anatomic variant in which the right common iliac artery overlies and compresses the left common iliac vein against the lumbar spine. Data regarding lower extremity trauma in patients with previously diagnosed MTS are rare. We discuss the operative approach for ankle trauma occurring 3 weeks after endovascular surgery for the treatment of MTS.

OBJECTIVE: Despite growing endovascular experience within the vascular surgery community, some catheter-based interventions - such as uterine artery embolization (UAE) - remain outside the clinical scope of most vascular surgeons, owing in part to established referral patterns and limited awareness among referring colleagues. We present our experience with a vascular surgery-based, multidisciplinary UAE program at an academic tertiary referral center. METHODS: In a collaborative effort between vascular surgery and gynecology, a Pelvic Vascular Disease Program has been established to provide palliative, prophylactic, and therapeutic embolizations including, but not limited to, UAE...
