Clinical guidelines on central venous catheterisation. Dehiscence of the skin with exposure of the port can be a result of an infection, but may also be caused by necrosis of skin, which can adhere to the port if there is insufficient subcutaneous tissue over the device. The objectives of this article are to review historical data on vascular access and discuss the implantation technique and the main complications associated with procedures for placement and use of totally implantable venous access devices.

Since part of the catheter remains outside of the body, exiting via the puncture site, they can cause discomfort. The tip could be misplaced because of technical failure during implantation, or as the result of migration after a successful implantation.

Chemotherapy is an option for a large proportion of cancer patients and since it is based on the infusion of intravenous drugs intermittently and for prolonged periods, totally implantable catheters are often chosen. When access is achieved via the internal saphenous or femoral veins, the port pocket can be constructed in the abdomen, medial of the anterior superior iliac crest, or on the anterolateral surface of the thigh Figure 5.

The detail contains the ultrasonographic image of the puncture, showing the tip of the tecnicca arrow inside the vein. Totally implantable venous catheters: Peripherally inserted central catheters PICCs are also inserted by puncture of a superficial vein, generally in an upper limb antecubital, basilic, cephalicor guided by ultrasonography USalso by puncture of the brachial vein.

Peripheral accesses are preferred for short-term infusion of solutions a few days in patients with a preserved venous network and for infusion of solutions that are not vesicant. In many cases, the tip of the catheter may enter the right atrium, without harming the patient. While waiting for the BC results, empirical treatment should cover both Gram-positive and Gram-negative agents. The likelihood of occurrence of catheter-related DVT is reduced by maintaining the tip of the catheter close to or within the right atrium, even in cases in which the device is implanted via a femoral or saphenous access.


Deep venous thrombosis DVT can cause signs and symptoms such as pain along the path of the vein, edema of a limb, facial edema, and presence of collateral venous circulation in the chest wall.

Historical development of vascular access procedures. Received Nov 17; Accepted Apr 4. In patients with cachexia, low-profile portals should be preferred. Nowadays, PICCs are increasingly fitted for patients on outpatient chemotherapy, because they allow intermittent use. An anterior chest wall that does not offer adequate conditions is a relative indication for choosing veins of the inferior vena cava system, since the port can be centrla in a number of alternative sites, such as the upper limbs.

While silicone offers better biocompatibility and lower risk of provoking thrombosis, 22 a polyurethane catheter has thinner walls, allowing a larger diameter internal lumen in relation to a silicone catheter with the same external diameter, resulting in a lower risk of obstruction.

Verso M, Agnelli G. If the catheter is still functioning correctly, it should be left in place, since there is no benefit from removing it and there is a risk of provoking additional venous thromboses by placing another catheter at a different site. There are versions with single or multiple lumens, and selidnger are always for continuous use, exclusively in patients who have been admitted to hospital. Variations in implantation technique and differences related to occurrence of complications and their management may be related to institutional issues, which should motivate every oncology center to monitor the progress of their patients who have totally implantable catheters.

History of vascular access. Totally implantable femoral vein catheters in cancer patients.


International clinical practice guidelines for the treatment and prophylaxis of thrombosis associated with central venous catheters in patients with cancer. A simple X-ray may show the catheter detached from the port or completely fractured and possible embolization of the catheter. Patients with esldinger or fungemia that persists for 72 hours after removal of the catheter should be vneoso antibiotic therapy for 4 to 6 weeks.


No conflicts of interest declared concerning the publication of this article. Postmortem dissections showed that the point at which the catheters entered the subclavian vein was close to the junction with the internal jugular vein.

Author information Article notes Copyright and License information Disclaimer. Removal is restricted to cases in which the catheter is no longer patent, which happens when the DVT involves the tip of the device. Author information Copyright and License information Disclaimer. Formation of fibrin at the catheter tip; A Clot or fibrin inside the catheter lumen; B Thrombus primarily involving the external part of the catheter, which may act as a valve mechanism, preventing reflux of blood when negative pressure is generated; C Thrombosis enveloping the circumference of the tip of the device, significantly obstructing the catheter lumen.

Profesor Asociado en Ciencias de la Salud. The theoretical advantage of valved catheters is to reduce the occurrence of malfunction caused by intracatheter thrombi, by preventing inadvertent reflux of blood.

These catheters have a diameter less than 10 Fr and can be implanted via a peripheral or central vein and, after taking a subcutaneous path, are connected to a reservoir port that is generally implanted over the muscular fascia of the site chosen for construction of the pocket that will accommodate the port.

Fever and shivering are generally associated with BSI, but these are nonspecific symptoms. Advertir los diferentes tipos y utilidades de los materiales de seguridad existentes en el mercado en estos momentos. Comparative study of valved and nonvalved fully implantable catheters inserted via ultrasound-guided puncture for chemotherapy. HISTORY 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.

When a BSI is suspected, paired blood cultures BC should be conducted aerobic and anaerobic of samples from the central catheter and from the peripheral vascular access.
