The aim of this study was to observe and analyze the causes of misplacement of peripherally inserted central catheters (PICCs) in patients with cancer. A total of 3,012 patients who underwent insertion of a PICC were reviewed from August 2000 to March 2012. The locations of the tube tips were recorded by chest X-ray examination. Malposition of the PICC was observed in 237 cases (7.87%), with th...

Venous malformations have static venous lakes that predispose to spontaneous venous thrombosis within the malformation due to its low-flow static state. Thrombi of varying sizes can then embolize continually into the pulmonary arterial circulation, and occlude and narrow elastic pulmonary arteries causing chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary thromboendarterectomy (PT...

OBJECTIVES Review of limb arterial injuries associated with limb fractures. DESIGN Retrospective study. SETTING University Hospital. MATERIALS AND METHODS The clinical presentation, assessment and management of 25 patients with upper (seven) and lower (18) limb arterial injuries associated with limb bone fractures has been retrospectively reviewed. MAIN RESULTS Five patients presented w...

Migration of an implantable port catheter tip is one of the well-known complications of this procedure, but the etiology of this problem is not clear. We describe here a case of migration of the tip of a port catheter from the right atrium to the right axillary vein in a patient with severe cough. Coughing was suggested for this case as the cause of the catheter tip migration. We corrected the ...

Background A long-axis in-plane (LA-IP) approach and a short-axis out-of-plane (SA-OOP) approach are the two main approaches used in ultrasound (US)-guided vascular catheterization. However, the efficacy and safety of these approaches remain controversial. Therefore, we performed this meta-analysis to compare the two techniques in vascular catheterization. Materials and methods Relevant studi...

Methods Randomized non-inferiority single-centre study. All patients admitted in intensive care unit (ICU) or operating room, requiring a central vein catheterization (CVC) without contraindication for SVC, were randomly assigned to subclavian or axillary groups. The primary endpoint was to compare success rate of each approach. The secondary endpoints were: strategy success rates, catheter pos...

Paget-Schroetter syndrome, also known as effort thrombosis, is a relatively rare disease process characterized by primary thrombosis to the subclavian and axillary veins. It usually presents in younger individuals, commonly affecting the dominant side upper extremity, and the diagnosis relies on a combination of imaging, laboratory tests, and clinical presentation. Upper extremity deep vein thr...
