ObjectiveTo review the current progress of treatment of cubital tunnel syndrome (CTS). MethodsRecent relevant literature on the treatment of CTS was extensively reviewed and summarized. ResultsCTS is one of the most common peripheral nerve compression diseases.The clinical presentations of CTS consist of numbness and tingling in the ring and small fingers of the hand,pain in the elbow and sensory change following long-time elbow bending.Severe symptoms such as weakness or atrophy of intrinsic muscles of the hand and claw hand deformity may occur.The etiology of CTS is ulnar nerve compression caused by morphological abnormalities and nerve paralysis after elbow trauma.CTS can be treated by nonsurgical methods and surgery.Surgical options include in situ decompression,ulnar nerve transposition,medial epicondylectomy,and endoscopic release. ConclusionThere are multiple options to treat CTS,but the indication and effectiveness of each treatment are still controversial.Further studies are required to form a generally accepted treatment system.
ObjectiveTo analyze risk factors of early outcomes of mitral valvuloplasty (MVP)for the treatment of degenerative mitral regurgitation (DMR). MethodsClinical data of 132 DMR patients who underwent MVP in Fu Wai Hospital between January 1, 2011 and November 1, 2011 were retrospectively analyzed. A total of 114 patients (86.4%)were followed up after discharge with their mean age of 51.21±12.78 years, including 76 males (66.7%). Preoperative risk factors of early outcomes of MVP were analyzed. ResultsAmong those patients, there were 25 patients with atrial fibri-llation (AF)(21.9%). Preoperative ejection fraction was 63.88%±6.93%. Preoperative echocardiography showed left ventricular end-diastolic diameter (LVEDD)was 31.61±5.51 mm/m2. There were 66 patients (57.9%)with tricuspid regurg-itation, and 34 patients (29.8%)underwent concomitant tricuspid valvuloplasty including 10 patients (8.8%)who received tricuspid annuloplasty rings. Two patients died postoperatively, 2 patients underwent re-operation of mitral valve replacement or MVP respectively. Postoperative echocardiography showed moderate or severe mitral regurgitation in 15 patients. Preoperative risk factors of early outcomes of MVP included AF (36.8% vs. 18.9%, P=0.035), large LVEDD (34.02±3.76 mm/m2 vs. 31.15±5.68 mm/m2, P=0.042)and functional mitral regurgitation (15.8% vs. 1.1%, P=0.007). Multivariate analysis showed greater postoperative LVEDD reduction significantly lowered the incidence of postoperative events (HR 0.002, 95% CI < 0.001-0.570, P=0.031). ConclusionsEnlargement of the left ventricle is an independent preoperative risk factor for early outcomes of MVP for DMR patients. Greater postoperative LVEDD reduction significantly lowers the incidence of postoperative events.
