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 aneurysms represent an unusual vascular disease that has been encountered with increasing regularity in clinical practice. In part, this reflects their frequent incidental recognition as a consequence of the proliferation of noninvasive imaging for nonvascular diseases. The incidence…
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…
Open renal revascularization for renovascular hypertension is being performed less often given advances in endovascular therapy. In fact, currently most renal artery bypass procedures are undertaken as part of hybrid operations accompanying endovascular interventions for aortic aneurysmal disease. Alternatives to…
Renal revascularization is indicated for renin-mediated hypertension and for progressive renal insufficiency secondary to renal artery arteriosclerosis. Renal artery atherosclerotic lesions account for 90% of all renal artery stenoses and are most often a manifestation of generalized atherosclerosis. Operative options…
Two questions arise when an arteriosclerotic renal artery stenosis is identified. First, is it a contributing factor to the patient’s hypertension or renal insufficiency? Second, if stenosis is a contributing factor and an operative intervention is deemed appropriate, is an…

Renal artery occlusive disease is the most common cause of surgically correctable hypertension in adults and in some instances contributes to deterioration in kidney function. It is a less common cause of secondary hypertension in pediatric patients. Pathologic processes causing…
