Conclusion: It should be feasible and necessary to measure three representative hemodynamic parameters (RAR, RPSV, and RIR or RSR) in the diagnosis of :50% RAS. The PSVs in the abdominal aorta and renal artery can be affected by factors other than RAS, which may decrease the accuracy of RAR. However, post-PSV ratios are minimally Selleckchem AG-120 affected by PSV in the abdominal aorta or by all equal proportional change in PSVs in the renal artery trunk and its intrarenal renal arteries; therefore, use of post-PSV ratios dramatically overcomes some limitations of RAR.”
“Objectives. Isolated dissection of a splanchnic artery, including the celiac artery, superior mesenteric artery (SMA), and inferior mesenteric artery, and their branches,
is a relatively rare condition. This study was conducted to define the characteristics of patients with splanchnic artery dissection and the clinical MK-2206 in vivo course of isolated splanchnic artery dissection.
Methods. The records of 19 patients were reviewed to survey demographic data, the location of dissection, symptoms, diagnostic modalities, treatment,
and long-term outcome.
Results. The locations of dissection were the superior mesenteric artery (SMA) in 11 patients, celiac artery in 3, both celiac artery and SMA in 2, and common hepatic artery, celiac artery to splenic artery, and celiac artery to proper hepatic artery in 1 each. In all but one with systemic sclerosis and Sjogren syndrome, the underlying cause of dissection was unclear. There were 12 asymptomatic and seven symptomatic patients. All cases were diagnosed by computed tomography. Surgical treatment was performed in one patient with a large aneurysm of the common hepatic artery, and the remaining 18 patients were followed-up conservatively. The mean follow-up duration was 20.9 +/- 25.4 months (range, 2-116 months). No expansion or progression of the false lumen was observed in these patients.
Conclusion: Patients with spontaneous dissection of the splanchnic arteries are often asymptomatic, and in this series, none developed significant end organ ischemia. Most patients with this rare condition can be managed expectantly with clinical follow-up including
computed tomography imaging to assess aneurysm formation.”
“Objective: The aim of this study was to analyze our 25-year experience with surgical treatment of selleck chemical visceral artery aneurysms (VAAs), with particular attention paid to early and long-term results.
Materials and Methods. From January 1982 to September 2007, 55 patients (32 males, 58%, and 23 females, 42%) underwent surgical treatment of 59 VAAs. Only one patient was treated with an endovascular procedure. Mean patient age was 59.3 years (range, 36-78 years). The site of aneurysmal disease was splenic artery in 30 (50.8%) cases, renal artery in nine (15.2%) cases, common hepatic artery in seven (11.9%) cases, pancreaticodundenal artery in four (6.8%) cases, celiac trunk in three (5.
