PURPOSE: Multi-phase post-mortem computed tomography angiography (MPMCTA) is a new diagnostic tool, used in forensic pathology. On the one hand, this technique allows a better and direct visualization of vascular and solid organ lesions. On the other hand, the invasiveness of the procedure-which requires surgical denudation (inguinal and/or cervical) and the insertion of surgical cannulas-leads to many relatives refusing scientific autopsies. Our hypothesis states that a minimally-invasive procedure combining interventional radiological techniques with MPMCTA (replacement of surgical cannulas by radiological catheters) will improve the approval rate of scientific autopsies by families...

: 1. Parallels in the evolution of x-ray angiographic systems and devices used for minimally invasive endovascular therapy Charles Strother - DSA, invented by Dr. Charles Mistretta at UW-Madison, was the technology which enabled the development of minimally invasive endovascular procedures. As DSA became widely available and the potential benefits for accessing the cerebral vasculature from an endovascular approach began to be apparent, industry began efforts to develop tools for use in these procedures...

PURPOSE: To characterize changes in radiation dose after introducing a new real-time image processing technology in interventional radiology systems. METHODS: Interventional radiology (IR) procedures are increasingly complex, at times requiring substantial time and radiation dose. The risk of inducing tissue reactions as well as long-term stochastic effects such as radiation-induced cancer is not trivial. To reduce this risk, IR systems are increasingly equipped with dose reduction technologies...

Lower gastrointestinal bleeding is most commonly associated with diverticulosis, ischemic colitis, vascular ectasia, and anorectal disease and less commonly associated with colonic malignancy. Infrequently, it is associated with mesenteric varices, a rare etiology that is not well documented in the radiology literature. We present a case of a 50-year-old man diagnosed as having intermittent left colonic bleeding from mesenteric varices due to a critical stenosis at the portal vein-inferior mesenteric vein confluence...

Midaortic syndrome (MAS) is a rare vascular disease that commonly causes renovascular hypertension. The lumen of the abdominal aorta narrows and the ostia of the branches show stenosis. MAS is associated with diminished pulses in the lower extremities compared with the upper extremities, severe hypertension with higher blood pressure in the upper rather than lower extremities, and an abdominal bruit. The clinical symptoms are variable, and recognition in children with hypertension can aid early diagnosis and optimal treatment...

BACKGROUND: Renal artery dissection is a condition that has been associated with traumatic injuries and connective tissue disorders. It has been managed in the past by multiple methods because there is no standard treatment, including vascular intervention with angioplasty and stenting, anticoagulation/antiplatelet therapy, and hypertension management. CASE PRESENTATION: We present a case of a spontaneous renal artery dissection in a 55-year-old white man with no traditional risk factors who presented twice to our emergency department in a 2-day period with different symptoms; on his first presentation he presented with symptoms consistent with renal colic and on the second visit he presented with symptoms consistent with aortic dissection...

Two decades of epidemiological research shows that silent cerebrovascular disease is common and is associated with future risk for stroke and dementia. It is the most common incidental finding on brain scans. To summarize evidence on the diagnosis and management of silent cerebrovascular disease to prevent stroke, the Stroke Council of the American Heart Association convened a writing committee to evaluate existing evidence, to discuss clinical considerations, and to offer suggestions for future research on stroke prevention in patients with 3 cardinal manifestations of silent cerebrovascular disease: silent brain infarcts, magnetic resonance imaging white matter hyperintensities of presumed vascular origin, and cerebral microbleeds...

Percutaneous endovascular techniques are used increasingly in the vascular armamentarium. Commonly performed as day case procedures under local anaesthetic, they are suited to the highly co-morbid vascular patient population. Furthermore, technological advances have resulted in ever improving outcomes for aneurysmal and occlusive disease. Endovascular procedures such as endovascular aneurysm repair or iliac artery stenting are traditionally associated with reduced infectious complications compared to equivalent open techniques...

INTRODUCTION: The management of active bleeding with haemodinamic lability in the paediatric trauma patient is difficult and generally leads to damage control surgery. Vascular Interventional Radiology (VIR) techniques are useful for the diagnosis as for the definitive treatment. AIM: The aim of our study was to describe our experience and evaluate effectiveness of VIR in the management of the paediatric trauma patient with active bleeding signs. METHODS: Retrospective analysis (2003-2014) of politraumatic patients who showed contrast blush on computed tomography and then treated by VIR techniques...

Long Wang, Xiang'en Shi, Fangjun Liu, Hai Qian
Fusiform dilation of the internal carotid artery (FDICA) is an infrequent vascular complication following resection of suprasellar lesions in the pediatric population, and its course appears to be benign without apparent clinical symptoms. However, data correlating symptomatic FDICA with bypass surgery are scarce. The authors here report 2 symptomatic cases that were treated using internal maxillary artery bypass more than 5 years after total removal of a craniopharyngioma at an outside institution. Both cases of FDICA were resected to relieve the mass effect and to expose the craniopharyngioma...
