[Venous lesions in relation to injections and the use of catheters].

The point of this study is to draw attention to the many complications which are likely to arise when the venous network is injected or cathetered. The main complications affecting the peripheral veins are lesions at the puncture point, cutaneous necroses in the case of paravenous injections, accidental intra-arterial injection, and chemical and bacterial thrombophlebites. The catheterism of intrathoracic veins can cause lesions at the puncture point (pneumothorax, lesion of the carotid), wrong positioning of the catheter and of the vascular or cardiac perforations, and central venous thromboses responsible for septicemic conditions and/or pulmonary embolism.
