In some cases, pleural effusion is formed when not successful medical intervention. The most common cause of iatrogenic pleural effusion is the inaccurate percutaneous insertion of a catheter into the central vein and its abdomen. giving to the mediastinum or pleural cavity. Pleural effusion may occur during jugular catheterization. and subclavian vein . When you break or puncture one of the vessels, the pleural fluid can be very bloody . At the same time, in other cases of pleural effusions of iatrogenic origin, the pleural fluid can be pure, without admixture of blood or with a small admixture of blood. and its composition may not differ from the intravenous pain some liquid. Of course, if blood is injected, pleural the liquid may be bloody even in the absence of significant bleeding from the damaged vessel to the chaff ral cavity . The possibility of unsuccessful catheterization of the central veins should be borne in mind in all patients in whom During transfusion, there is a rapid accumulation of pleural fluid. Diagnostic thoracocentesis in such patients reveals a blood or fluid identical to that administered intravenously. In any case, the catheter from the central vein should be removed. If fresh blood is available, the pleural cavity should be drained immediately. If the blood the course does not stop, a trial thoracotomy may be required.
Pleural effusion can form as a complication of aortographic examination of the abdominal aorta . This is usually a small pleural effusion, which is detected on the radiograph in the prone position . It is believed that this effusion results from the passage of a needle through the lower nude part of the pleural cavity. The exudative pleural effusion is formed as a result of pleural irritation. Lost extravasal administration of contrast agent. Plev effusion-sectoral formed by aortography abdominal aorta you, in some cases, can be very bloody, which is probably the result of blood getting from the aorta into the pleural cavity. In such cases, it is usually sufficient to Lime patient therapeuticthoracocentesis , because blood flow stops spontaneously
