Quantitative analysis of venous outflow with photo-plethysmography in patients with suspected thoracic outlet syndrome.
Front Cardiovasc Med
October 2022
Vascular Medicine, University Hospital, Angers, France.
Background: Venous compression is the second most frequent form of thoracic outlet syndrome (TOS). Although venous photo-plethysmography (PPG) has been largely used to estimate the consequences of chronic thromboses (Paget Schroetter syndrome), systematic direct quantitative recording of hemodynamic consequences of positional venous outflow impairment in patients with suspected TOS has never been reported.
Objective: We hypothesized that moving the arms forward (prayer: "Pra" position) while keeping the hands elevated after a surrender/candlestick position (Ca) would allow quantification of 100% upper limb venous emptying (PPGmax) and quantitative evaluation of the emptying observed at the end of the preceding abduction period (End-Ca-PPG), expressed in %PPGmax.
[Prevention from PICC-related venous thrombosis in the upper limbs of malignant tumor patients with moxibustion combined with plucking at Jiquan (HT 1): a randomized controlled trial].

Department of Hematology, First Affiliated Hospital of Guangzhou Medical University, Guangzhou 510230,Guangdong Province, China.
Objective: To observe the clinical effect of moxibustion combined with plucking technique at Jiquan (HT 1) for preventing peripherally inserted central catheter (PICC)-related venous thrombosis in the upper limbs of malignant tumor patients.
Methods: A total of 80 malignant tumor patients undergoing PICC were randomized into an observation group and a control group, 40 cases in each one. In the control group, the routine care for PICC was exerted.
The inside-out technique is safe and effective for thoracic central venous obstruction.

Department of Surgery, University of Kentucky College of Medicine, Lexington, KY. Electronic address:
Background: Thoracic central venous obstruction (TCVO) presents a challenging scenario for patients requiring central venous access. The inside-out technique for crossing occluded veins has been described; however, to date, case series have reported on a limited number of patients. The purpose of the present study was to evaluate the indications for, efficacy of, and outcomes with the inside-out technique at a single tertiary academic center, with close attention to the severity of TCVO using the Society of Interventional Radiology (SIR) TCVO classification.

Head and Neck Surgery, Miyagi Cancer Center, Natori, JPN.
We report here a patient with a massive lymphatic metastasis involving the internal jugular-subclavian venous (IJ-SCV) junction that was safely resected with a new surgical procedure without significant complications. The patient, a 57-year-old man, had advanced hypopharyngeal cancer that had metastasized to the left IJ-SCV junction with a considerable invasion of the vessels, seemingly precluding a conventional surgical intervention. We, therefore, devised a new minimally invasive surgical approach involving resection of the margin of the medial clavicle, which provided an open view of the operation field.

Radiology, University of Washington, Seattle, Washington, USA.
Objectives: To assess whether a limited ultrasound (US) scanning protocol to monitor the upper extremity peripherally inserted central catheter (PICC) location in neonates is feasible for experienced US operators.
Methods: A radiologist, who was blinded to the PICC location on chest radiography, performed 14 US scans on 11 neonates with upper extremity PICCs. A US machine with 13-6-MHz linear and 8-4-MHz phased array transducers was used for the examinations.
