A variety of demographic, lesion-related and procedure-related variables were evaluated for potential impact of technical success and patency. The follow-up protocol included clinical assessment, and color and spectral Doppler evaluation of the stented vessel(s).
Results: The clinical presentation was chronic mesenteric ischemia in 12 patients, acute mesenteric vascular syndromes in 10 patients, foregut ischemia/ischemic pancreatitis in three patients, and prior to endovascular repair of aortic aneurysm in one this website patient. The treated vessel was SMA in 22 procedures, CA in three, and both SMA and CA in one. Technical success was achieved in 23 of the 27 attempted recanalizations (85%). Three patients
who failed the attempt underwent open bypass, and another one underwent retrograde recanalization and stenting of the SMA. Procedure success was only significantly
related to patient age <70 years or procedure performance after the year 2006. Notably, the presence of a stump, ostial plaque, extensive vascular calcification, recanalization mTOR inhibitor route (intraluminal vs subintimal), occlusion length, and vessel diameter had no significant impact on procedure success. Traditional duplex criteria proved unreliable in predicting restenosis. Life table analysis of freedom from symptom recurrence showed a primary and assisted rates of 58% and 80% at 1 year, and 33% and 60% at 2 years, respectively. Clinical recurrences developed in six patients (four presented with abdominal angina and weight loss, two presented with abdominal catastrophe). There were six access-related complications Adenosine and no procedural deaths. Four delayed deaths occurred during follow-up (two cardiac causes, two due to abdominal sepsis).
Conclusions: Endovascular recanalization of mesenteric artery occlusion is both feasible and successful, provided careful planning is used. (J Vasc Surg 2012;55:1674-81.)”
“Many studies have investigated hypothalamus-pituitary-adrenal (HPA) axis responses to psychosocial stress in adults. In children, much less is known about HPA axis reactivity, and a sizable number of studies has
not detected a significant cortisol response. Moreover, there is a tack of studies comparing adults’ and children’s responses to identical stressors. The aim of the present study was to modify an existing laboratory stressor to serve as a potent stressor in children and to allow for direct comparison between children’s and adults’ stress responses. Thirty children, ages 9-12 (14 female), and 31 young adults, ages 18-25 (17 female), were exposed to the modified protocol (TSST-M). A significant increase in salivary cortisol was observed in response to the TSST-M, F(2.5, 125.4) = 19.65, p <.001, eta(2) = .28, and overall, no differences were found between children’s and adults’ responses, F(2.5, 125.4) = .31, n.s.
