Abstract
Complications due to subcutaneous devices are rare, mainly venous thrombosis, sepsis and uncommonly pneumothorax, but migration of the catheter has not been yet reported. In our institution about 820 subcutaneous central venous access devices for chemotherapy have been placed since 1985, mainly by a subclavicular access. We report here 2 cases of migrated catheters, (2.5/1000) one in both pulmonary arteries, the second in right ventricle and pulmonary artery, extracted by a non-invasive technique as out patients. Extraction of accidentally migrated catheters by lasso's technique is now well-known in vasculary radiology, and must be realized in a ward with continuous cardiologic survey and reanimation means. Catheter's crossing through the right ventricle composes the risk of this technique. Winding a “pig-tail” catheter round the migrated catheter allows its mobilization and removing to the right auricle. In a second step, a strong gripping of the catheter by the lasso permits the final extraction without any cardiac risk.
