Filter by:Lateral lumbar interbody fusion (LLIF), as a minimally invasive technique, is an indirect decompression technique, and its decompression effect is not as thorough as traditional posterior decompression surgery. For certain patients with severe lumbar stenosis, additional posterior decompression is required. However, whether additional posterior decompression is necessary for these patients is unknown. Radiographic predictors of failed indirect decompression via LLIF is unknown. In current randomized, controlled trial , the investigators compare the clinical outcomes of patients with severe lumbar stenosis who received LLIF plus posterior decompression and those without posterior decompression.
This study compare the results of 2 methods in surgical treatment of Lumbar spine stenosis.These are microdecompresssion and open decompression with posterior stabilization. 100 patients are involved in this study who divided in 2 groups.Each group was treated with one method and follow up done which showed both method are effective with better results in those patients treated with microdecomppression.
The main objective of the study is to compare the efficacy on back-specific activity limitations at 4 months after-randomisation of home-based cycling using connected ergometric bicycles associated with usual care to usual care.
It has been demonstrated that urethroplasty should be considered the gold standard treatment for urethral stricture disease as it yields higher long-term success rates than endoscopic treatment options such as direct vision internal urethrotomy (DVIU) or dilation. Many data about these procedures exist, although most of the publications about urethroplasty are retrospective and involve a tremendous risk of bias. To address these issues, this study is designed to prospectively gain evidence about this matter in all patient subgroups facing a potential treatment with urethroplasty: native men, native women, transmen, transwomen and children.
This study evaluates whether there is a correlation between intravascular injection rate and severity of cervical foraminal stenosis during cervical transforaminal epidural steroid injection
Evaluation of the FLEX Vessel Prep system combined with angioplasty in the treatment of arteriovenous access stenosis.
Optimize a candidate software algorithm using data collected with the Vivio system for use as an aid in the identification of heart sounds associated with severe aortic stenosis
TEAM-Br is a randomized, prospective, cost-utility study comparing transcatheter aortic valve implantation (TAVI) versus surgical aortic vale replacement in Brazil. The study is sponsored by the national Minister of Health, through PROADI-SUS (Programa de Apoio ao Desenvolvimento Institucional do SUS).
Evaluate the sensitivity and specificity of the Vivio System when used as an aid in the identification of heart sounds associated with severe aortic stenosis.
This study is to assess the clinical efficacy of epidural injections with Tumor Necrosis Factor-Alpha(TNF-α) Inhibitor in patients with chronic radicular pain caused by lumbar spinal stenosis.
