InHarvey described the circulatory system on the basis of studies in animals and 4 decades later Sir Christopher Vdnoso conducted the first intravenous infusions in living beings.

The technique described by Aubaniac involved a medial access, guiding the puncture laterally and inferiorly in the direction of the fossa adjacent to the sternum.

Hickman catheters offer the possibility of simultaneous infusion of different solutions, including blood products, in addition to their use for BMT. Conservative treatment does not generally achieve good results, and in the majority of cases the catheter has to be removed and systemic antibiotic therapy given.

Peripheral accesses are preferred for short-term infusion of solutions a few days in patients with a preserved venous network tfcnica for infusion of solutions that are not vesicant.

The vessel is ligated distally and a proximal ligature is placed around the catheter, taking care not to constrict it. In the case of larger caliber veins, a suture around the incision, rather than ligature, allows maintenance of blood flow, avoiding thrombophlebitis Figure 4.

An anterior chest wall seodinger does not offer adequate conditions is a relative indication for choosing veins of the inferior vena cava system, since the port can be placed in a number of alternative sites, such as the upper limbs. Diagnosis is achieved using imaging exams, such as venous duplex scan of the cervical and abdominal regions and of limbs.

Guidelines for the prevention of intravascular catheter-related infections. Venous thromboembolism associated with long-term use of central venous catheters in cancer patients. At rest, the slit remains closed. This can occur if the catheter becomes detached from the port or is fractured, which is more frequent in cases in which the device is implanted by puncture of the subclavian vein.

If the port becomes rotated, the puncture area will be against the chest wall and the base will be facing out, preventing puncture. The physiology of blood vessels began to be revealed in the seventeenth century when Harvey, who conducted experiments with animals, published a description of the circulatory system in the work Excercitatio Anatomica de Moto Cordis et Sanguinus in Animalibus. However, if the port is made from a radiotransparent material plasticpalpation should be sufficient for diagnosis, since the port will not be visible on the imaging exam.

Since part of the catheter remains outside of the body, exiting via the puncture site, they can cause discomfort.

Nowadays, primary failures of devices are rare, but can still be observed at high-volume centers.

Among the non-infectious complications recorded at our institution, there were 27 2. Totally implantable ports connected to valved catheters for chemotherapy: The main indications for totally implantable catheters ventral a need for frequent venous access, use of vesicant drugs, and a peripheral venous system that cannot be used for access.

If thrombosis is suspected in the venous brachiocephalic trunk or the superior vena cava, then computed tomography angiography or magnetic resonance angiography are more appropriate. With catheters that have a slit-shaped valve at the tip, a fibrin layer may not only prevent blood from being drawn, but also infusion of fluids.
