Emergency surgical repair for acute traumatic aortic ruptures has been associated with a high peri-procedural mortality rate. Endovascular stent-grafting, as a less invasive procedure, has shown encouraging results. This report describes a patient with a short landing zone, who was treated by transposing the supra-aortic branch without sternotomy, followed by covered stent-grafting with an exte...

In this article, a fast algorithm is developed to compute two-dimensional convolutions of an array of d 1· d 2 complex number points, where d 2 = 2 and d 1 = 2m -r+ 1 for some I ,.; r ,.; m. This new algorithm requires fewer multiplications and about the same number of additions as the conventional FFT method for computing the two-dimensional convolution. It also has the advantage that the oper...

Pror.*^ ? ns' interposition operation for prolapse ?aentia. The principle of the Watkins' operation is based on separating the bladder from the anterior wall of the nterus and transposing its attachment to the posterior wall, so that the uterus is left in a position to support the entire bladder. Watkins performed his first operation in 1898. Several modifications, notably that of Wertheim, hav...
