Pediatric arterial aneurysms include many rare and heterogeneic diseases. Etiologies vary widely among the different types of aneurysms, with important differences in the aneurysm’s character and clinical relevance often dependent on the specific vessel affected ( Table 186.1 ). Aneurysms…
Introduction Developmental renal artery and abdominal aortic disease is complex and the underlying pathogenesis in the majority of cases is poorly understood. Nevertheless, certain contributing factors are well recognized and the treatment of most lesions has become better defined in…
Aneurysms of the visceral branches of the abdominal aorta are being recognized with increasing frequency. More than half of the splanchnic and renal artery aneurysms described in the English-language literature have been reported in the past 25 years. Splanchnic aneurysms…
Renal artery occlusive disease affecting pediatric patients is an important but very uncommon cause of hypertension in children. Renal artery stenoses in this age group represent a wide spectrum of heterogeneous diseases, although developmental anomalies with concomitant narrowings of the…
Clinical Presentation Splanchnic arterial occlusive disease in children is a very uncommon pathologic entity and a rare cause of intestinal ischemic symptoms. This disease is usually recognized as an incidental finding during studies of hypertensive children having abdominal aortic coarctations…
Pediatric injuries and accidents are the most common causes of childhood death, and nonfatal injuries are innumerable in this age group. Conversely, iatrogenic trauma accounts for an extremely small subset of injuries occurring in childhood. These particular injuries are not…
Abdominal vascular trauma is quite infrequent within the broader context of all traumatic injuries. However, these injuries can have high morbidity and mortality. Their significant heterogeneity in acuity of presentation, associated morbidity, and recommended management styles make an algorithmic approach…
The mid-20th century saw the emergence of contrast angiography to clarify and define the extent of vascular wounds. Percutaneous catheter-based angiography began to replace surgical cutdown and needle injection of contrast in the 1950s and 1960s, and became the gold…
Focal developmental narrowings of the distal thoracic and abdominal aorta are rare anomalies accounting for less than 2% of all aortic coarctations. Most physicians have limited experience with the management of these unusual lesions. Abdominal aortic coarctations are categorized by…
