BACKGROUND: Our objective was to quantify variability across the UK in the management of a complex abdominal aortic aneurysm (AAA). METHODS: An online survey was emailed to all members of the Vascular Society for Great Britain and Ireland. The survey presented a vignette of a 63-year-old woman with significant respiratory co-morbidity whose computed tomographic (CT) angiogram demonstrated a 54 mm AAA with a short (7 mm) proximal neck but no other adverse morphological features for a standard or complex endovascular aneurysm repair (EVAR)...

Interventional radiology (IR) is a fast expanding field which includes vascular (arterial and venous) as well as non-vascular topics. IR is minimally invasive methods, which are performed under guidance of radiological modalities. The methods are in general patient-friendly and organ-sparing procedures and can often be performed on out-patient basis or with short admission to the hospital and with short reconvalescence and economic advantages compared with corresponding surgical treatments. IR has in some cases substituted former surgical procedures...

Interventional radiology plays a significant role in the treatment of bone metastases by various techniques, percutaneous or endovascular. Vertebroplasty is the most well-studied technique for stabilisation of spine metastases as it induces satisfactory stabilisation of the vertebra and offers clear improvement of the quality of life. Due to the success of this technique cementoplasty of other bones, mainly pelvic girdle, has been largely developed. The development of reinforced cementoplasty allows treatment of pre-fractural osteolysis of some long bones...

Hybrid operating rooms (HOR) are rooms that mix interventional radiology and surgical equipments. They are usually used in heart, vascular, orthopedic and neurosurgery, and make it possible to consider new minimally invasive procedures in urology. Thanks to these, we developed a new partial nephrectomy technique without renal pedicle clamping and without ischemia. Renal cancer is now diagnosed at localized stage in most of the cases, and its treatment is mostly based on nephron sparing surgery. However, the hemorrhagic character of this intervention requires a renal pedicle clamping whose long-term consequences on renal function are discussed...

Cystic adventitial disease (CAD) is a rare vascular pathology which predominantly affects peripheral vessels of young otherwise healthy males. Much debate exists regarding its exact etiology. It is characterized by a collection of mucinous material within the adventitial wall layer of the affected vessel, resulting in arterial stenosis and rapidly progressive calf claudication. Treatment is primarily surgical, although radiological interventions have been reported. Its rarity makes evidence-based surgical or radiological management difficult...

Hemodialysis catheters are associated with higher risks of complications compared to arteriovenous fistulas and grafts. Some common complications of dialysis catheters include infection, thrombus formation, central venous stenosis, and mechanical dysfunction. Rarely, catheters can become firmly adhered to a vessel wall. Catheter adhesion is a serious complication that can impact the delivery of safe and effective dialysis to affected patients. Adherent catheters commonly present insidiously with no overt diagnostic signs and symptoms or antecedent catheter malfunction...

Trauma is a leading cause of death in younger individuals. Blunt abdominal trauma has the potential to mask severe injuries-there can be serious organ or vascular injury underneath intact skin. Increasingly, there is a trend toward nonoperative management of blunt abdominal trauma. We report the case of a left hepatic artery transection managed in the interventional radiology suite.

Surgeons perceive that some surgical transfers are futile, but the incidence and risk factors of futile transfer are not quantified. Identifying futile interfacility transfers could save cost and undue burdens to patients and families. We sought to describe the incidence and factors associated with futile transfers. We conducted a retrospective cohort study from 2009 to 2013 including patients transferred to a tertiary referral center for general or vascular surgical care. Futile transfers were defined as resulting in death or hospice discharge within 72 hours of transfer without operative, endoscopic, or radiologic intervention...

Advances in robotic medicine have been adopted by various surgical subspecialties as the benefits of this technology become more readily apparent: precision in narrow operative windows, tremor controlled movements, and modestly improved outcomes, among others. Vascular neurosurgery, in particular, remains open to newer and more cutting edge treatment options for complex pathologies, and robotics may be on the horizon for such advances. We seek to provide a broad overview of these innovations in vascular neurosurgery for both practitioners well acquainted with robotics and those seeking to become more familiar...

BACKGROUND: The role of aggressive surgical manipulation with clot evacuation, arachnoid dissection, and papaverine-guided adventitial dissection of large vessels during ruptured aneurysm surgery in reducing vasospasm is controversial. Here we describe a single-institution experience in aneurysm surgery outcomes with and without aggressive surgery. METHODS: We performed retrospective analysis of all patients >18 years of age with subarachnoid hemorrhage (SAH) from anterior circulation aneurysms between 2008 and 2013 at the University of New Mexico Hospital...

Background  Kaposiform hemangioendothelioma (KHE) is a vascular tumor frequently associated with Kasabach-Merritt phenomenon (KMP), characterized by severe thrombocytopenia and consumptive coagulopathy. Visceral involvement in KHE is rare. In our recent experience, sirolimus has shown to be an effective treatment in cutaneous KHE, becoming indeed the treatment of choice in KMP. We report a case of pancreatic KHE associated with KMP and refractory to sirolimus. Case Report  A 4-month-old infant is referred for obstructive jaundice (10 mg/dL conjugated bilirubin) secondary to vascular pancreatic tumor...

BACKGROUND & AIMS: Standard endoscopic therapies do not control bleeding or produce complications in as many as 20% of patients with non-variceal gastrointestinal bleeding. Most bleeding comes from ulcers with characteristics such as high-risk vascular territories and/or large vessels. We evaluated the efficacy of using over the scope clips (OTSCs) as primary or rescue therapy for patients with bleeding from lesions that have a high-risk for adverse outcomes. METHODS: We performed a retrospective analysis of data from 67 patients with gastrointestinal bleeding from high-risk lesions who were treated with OTSC as primary (n=49) or rescue therapy (n=18) at a quaternary center, from December 2011 through February 2015...

Endoscopic ultrasound (EUS) has evolved from a purely diagnostic to an interventional modality offering minimally invasive alternatives to surgical and radiologic interventions. This has led to a rapidly growing interest in EUS-guided vascular interventions. EUS-guided portal venous access is an emerging technique which opens a new arena for interventional vascular EUS. Portal vein can be accessed under EUS guidance with high precision and low risk of complications thus expanding its application for both benign and malignant conditions...

BACKGROUND AND PURPOSE: Neuroendovascular surgery is a medical subspecialty that uses minimally invasive catheter-based technology and radiological imaging to diagnose and treat diseases of the central nervous system, head, neck, spine, and their vasculature. To perform these procedures, the practitioner needs an extensive knowledge of the anatomy of the nervous system, vasculature, and pathological conditions that affect their physiology. A working knowledge of radiation biology and safety is essential...
