Background: We sought to determine the outcomes in patients presenting with venous thoracic outlet syndrome.
Methods: Prospectively collected data from 67 patients between October 2003 and December 2007. The average age was 31 years (range, 16-54); the 37 males and 30 females presented on average 9.2 months (range, 1 month-6 years) after acute thrombosis. Four treatment algorithms were utilized.
Results: In group 1, 3 patients presented with acute occlusion and received tissue plasminogen activator (tPA) and immediate first rib resection with scalenectomy (FRRS). One vein rethrombosed and was treated by intravenous tPA postoperatively. In group 2, 39 patients presented with stenotic subclavian veins an average of 22 weeks after their initial thrombosis, all of whom underwent FRRS followed by a venogram 2 weeks postoperatively: 25 had a tight stenosis and underwent venoplasty with anticoagulation; 13 had patent, nonstenotic subclavian veins, and 1 patient required tPA and venoplasty owing to rethrombosis. Two patients had their subclavian vein thrombose after venoplasty and were treated with anticoagulation, tPA, and venoplasty. In group 3, 11 patients presented with intermittent venous obstruction without thrombosis and underwent FRRS; 3 underwent venograms because of concerns of residual stenosis, 2 of whom required venoplasty postoperatively. Finally, in group 4, 14 patients presented with occluded subclavian veins and underwent FRRS with long-term anticoagulation. Eleven have recanalized at an average of 6 months (range, 2-12).
Conclusion: Overall, 64 of 67 patients have patent subclavian veins after a median follow-up of 10 months, and all patients are asymptomatic for a success rate of 96%. Tailored treatment algorithms including FRRS, postoperative venograms with or without intervention, and the use of long-term anticoagulation seems to be required in this complicated group of young patients to achieve optimal results.

Objective: Despite diagnostic criteria refinements, Parkinson's disease (PD) clinical diagnosis still suffers from a not satisfying accuracy, with the post-mortem examination as the gold standard for diagnosis. Seminal clinicopathological series highlighted that a relevant number of patients alive-diagnosed with idiopathic PD have an alternative post-mortem diagnosis. We evaluated the diagnostic accuracy of PD comparing the in-vivo clinical diagnosis with the post-mortem diagnosis performed through the pathological examination in 2 groups.

Background: Kidney tumors, common in the urinary system, have widely varying survival rates post-surgery. Current prognostic methods rely on invasive biopsies, highlighting the need for non-invasive, accurate prediction models to assist in clinical decision-making.
Purpose: This study aimed to construct a K-means clustering algorithm enhanced by Transformer-based feature transformation to predict the overall survival rate of patients after kidney tumor resection and provide an interpretability analysis of the model to assist in clinical decision-making.

Background: Tumor size (TS) in pancreatic ductal adenocarcinoma (PDAC) is one of the most important prognostic factors. However, discrepancies between TS on preoperative images (TSi) and pathological specimens (TSp) have been reported. This study aims to evaluate the factors associated with the differences between TSi and TSp.

Objectives: This study evaluates the potential of pulp volume/total tooth-volume measurements of canine teeth in relation to chronologic age in patients with cleft lip and palate (CLP). The significance of this study lies in its exploration of the usability of these measurements for age determination in CLP patients, providing a novel perspective to the existing literature.
Methods: Cone beam computed tomography images of 33 patients (16 females, 17 males) with unilateral CLP aged 14-45 years and 33 age- and sex-matched healthy individuals (16 females, 17 males) were retrospectively evaluated.
