A fatal case of Rosai-Dorfman disease.

As Rosai-Dorfman Disease presents generally nonspecific symptoms, differential diagnosis can be of great learning curve for physicians. Additionally, RDD does not usually threaten life and spontaneous remission is frequently observed. However, unusually in our case the patient passed away within 1 month of confirmed diagnosis.

The role of peripheral vascular resistance in determining the infrainguinal arterial reconstruction patency.

Objective: To find if there is any correlation between the peripheral vascular resistance, its change following an intragraft prostaglandin infusion and the infrainguinal reconstruction patency.

Patients And Methods: Ninety-seven patients with infrainguinal reconstructions were included in the study: in 48 patients they were compromised (32 with graft thrombosis and 16 with stenosis of the distal anastomoses); 49 patients had their bypasses patent for no less than 12 months. Intraoperative flowmetry was performed on the target artery under the distal anastomosis, after declamping, and after a five-minute intragraft prostaglandin infusion.
