Microvascular decompression (MVD) is a standard surgical procedure for treating vascular compression syndromes. There are two basic ways to perform MVD: interposition using a prosthesis and transposition. With the transposition technique, adhesions and granuloma around the decompression site are avoided, but the required operation is more complex than that for the interposition method. We descr...

Test data compression is an effective methodology for reducing test data volume and testing time. In this paper, we present a new test data compression technique based on block merging. The technique capitalizes on the fact that many consecutive blocks of the test data can be merged together. Compression is achieved by storing the merged block and the number of blocks merged. It also takes adva...

stage osteonecrosis of the femoral head (ONFH), the factors normally considered are the progression of the disease and the patient’s age. Although most clinicians agree that the focus, when first treating patients under 50 years of age, should be on preserving the joint, there is significant controversy as to the appropriate procedure in any given case. Core decompression is one of the joint sa...

This paper presents an FPGA-based design and implementation of a three dimensional (3D) triangle mesh decompressor. Triangle mesh is the dominant representation of 3D geometric models. The prototype decompressor is based on a simple and highly efficient triangle mesh compression algorithm, called BFT mesh encoding [10, 11]. To the best of our knowledge, this is the first hardware implementation...

AIMS To document the successful treatment of five patients with dysthyroid optic neuropathy by orbital fat decompression instead of orbital bone decompression after failed medical therapy. METHODS Eight orbits of five patients with dysthyroid optic neuropathy were selected for orbital fat decompression as an alternative to bone removal decompression. Treatment with systemic corticosteroids an...

The veins are a major site of bubble formation after decompression and the lung is a target organ of bubbles. Bubble-induced inflammation has been implicated in the pathogenesis of decompression sickness (DCS). Macrophages play a central role in the inflammation, and macrophage polarization is closely related to the pathogenesis of some lung diseases. This study aimed to investigate the blood m...

The natural history of Chiari malformation and our ability to alter it is poorly understood, and reported results of hindbrain decompression show high recurrence rates. We report 11 years of experience of hindbrain decompression, to evaluate long-term outcome related to surgical technique. The results of patients who underwent hindbrain decompression between 1994 and 2005 were retrospectively a...

We describe a consecutive series of 26 patients with simple bone cysts who were treated by curettage, multiple drilling and continuous decompression by the insertion of either a cannulated screw or a pin. In the first 15 patients we used titanium cannulated screws (group 1) and in the next 11 a cannulated hydroxyapatite pin (group 2). Satisfactory healing was achieved in 12 patients in group 1 ...
