Teflon guide-wire-assisted semi-closed Vollmar endarterectomy of the superficial femoral artery. A review of 25 cases and the state of the art from a literature review.

In this retrospective study, we analysed 25 guide-wire-assisted Vollmar endarterectomies of an occluded superficial femoral artery. In 96% of the cases, the patient suffered from a Fontaine stage III or IV. After a mean follow-up of 24.

Radical cystectomy with or without urethrectomy?

After the introduction of bladder replacement procedures, the indications for prophylactic urethrectomy have become more and more restricted. While years ago, a prophylactic urethrectomy was performed in many patients with cutaneous diversions, it has become clear that only patients with invasion by transitional cell carcinoma at the level of the prostatic urethra or bladder neck have a substantial risk of developing subsequent urethral recurrence. The pre- or intra-operative assessment of the prostatic urethra in males and of the bladder neck in females is the key to appropriate management of the urethra in patients with bladder cancer.

[Three-dimensional imaging of acetabular fractures using spiral CT].

Seven adult patients with acetabular fractures were investigated with conventional X-rays, axial spiral computed tomographic (CT) images and three-dimensional (3D) surface rendered reconstructions. Spiral CT has the advantage that it acquires the data much faster than incremental CT, resulting in less motion artefacts. A semi-automatic three-dimensional environment for segmentation has been developed in our institution.
