NCT06059612
Superior cluneal nerve entrapment (SCN) is a painful symptomatic condition related to compression by the thoracolumbar and gluteal bands of nerve outcrop, above the iliac crest. This syndrome is not considered in the classical differential diagnosis of lumbosacral spine disorders and is almost unknown in Italy. It is a neuropathic pain, acute, subacute, or chronic, evoked by mechanical stress at the level of the sensory territory corresponding to the superior cluneal nerve, easily found anatomically and evoked at a trigger point on the posterior iliac crest approximately 70mm from the midline and 45mm from the posterior superior iliac spine. SCN entrapment syndrome represents a not so infrequent syndrome. It is easily framed and treatment is effective in most cases. Therefore, diagnosis and treatment of this syndrome represents an excellent option in all those patients with low back pain that cannot be otherwise framed and resolved.
NCT07309705
The goal of this observational study is to learn whether a digital angiography derived fractional flow reserve (DPR) measurement can improve the prediction of stroke risk in adults with symptomatic intracranial atherosclerotic stenosis, defined as 50 to 99 percent narrowing. The main questions it aims to answer are: Does DPR identify patients who are at higher risk of recurrent stroke despite receiving standard medical treatment? Is DPR more accurate than traditional angiographic stenosis measurements for assessing the functional severity of intracranial arterial disease? Participants will undergo routine digital subtraction angiography as part of their clinical evaluation. Their angiographic images will be analyzed using a computational method to estimate blood flow impairment, and they will be followed for up to 12 months to monitor stroke related outcomes.
