The Influence of Arm Positioning on Ultrasonic Visualization of the Subclavian Vein
Anesthesia and Analgesia, 2016Co-Authors: Meriem Sadek, Claire Roger, Sophie Bastide, Pascal Jeannes, Kamila Solecki, Audrey De Jong, Gautier Buzançais, Loubna Elotmani, Jacques Ripart, Jean Yves LefrantAbstract:We hypothesized that placing the arm in 90° abduction, through 90° flexion and 90° external rotation, could improve ultrasound visualization of the Subclavian Vein. In 49 healthy volunteers, a single operator performed a view of the Subclavian Vein in neutral position and abduction position. A second blinded operator measured the cross-sectional area of the Subclavian Vein. Abduction position increased the cross-sectional area of the Subclavian Vein from 124 ± 46 (mean ± SD) to 162 ± 58 mm (P = 0.001). An increase of the cross-sectional area of ≥50% was observed in 41% volunteers (95% confidence interval, 27%-56%, n = 20); this technique offers an alternative approach (maybe safer) for ultrasound-guided catheterization of the Subclavian Vein.

Pulsed Doppler ultrasonography guidance for catheterization of the Subclavian Vein: a randomized study.
Anesthesiology, 1998Co-Authors: Jean Yves Lefrant, Philippe Cuvillon, J. F. Benezet, Michel Dauzat, Pascale Peray, Gilbert Saissi, Jean-emmanuel De La Coussaye, Jean-jacques EledjamAbstract:BackgroundCatheterization of the Subclavian Vein may lead to severe complications. The current randomized study compared a technique of pulsed Doppler ultrasonography guidance and the standard method for Subclavian Vein catheterization.MethodsStandard and Doppler ultrasonography guidance methods wer

thoracic outlet decompression for Subclavian Vein thrombosis experience in 71 patients
Archives of Surgery, 2005Co-Authors: Vasu Divi, Mary C Proctor, David A Axelrod, Lazar J GreenfieldAbstract:Hypothesis There is a difference in outcomes when patients have neurogenic thoracic outlet syndrome in addition to Subclavian Vein thrombosis. Methods Analysis of a prospectively developed database, medical record review, and a patient questionnaire were used to summarize clinical experience from December 1990 to December 2001 on the basis of the patient’s original evaluation. Patients were stratified on the presence (group 1) or absence (group 2) of additional neurogenic pathologic features. Results Of 928 patients evaluated for thoracic outlet syndrome, 71 underwent 73 operative procedures for Subclavian Vein obstruction. Men predominated (55%), and the mean age was 32 years. Group 1 (41%) had more preoperative disability, a higher incidence of persistent pain (24%), and less likelihood of returning to full activity compared with group 2 (67% vs 93%; P = .01). Catheter-directed thrombolysis was used in 65% of Veins. Preoperative balloon angioplasty was used selectively (34%), and only 4% required stents. Supraclavicular decompression and venolysis were usually delayed 3 weeks to allow for healing of the venous endothelium. Complications included wound infection (3%) and postoperative hematoma (8%). Conclusions Patients with isolated Subclavian Vein obstruction have a more favorable outcome relative to those with combined neurogenic and venous pathologic features. Decompression following thrombolysis should be delayed to reduce the incidence of postoperative complications.
