Procedimiento del cateterismo venoso central. 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. When the option chosen is dissection of a superficial vein, a venotomy is performed to allow the catheter to be inserted and advanced until the tip reaches the central position.

A simple X-ray may show the catheter detached from the port or completely fractured and possible embolization of the catheter.

If the catheter is correctly positioned, without excessive angulation and with no signs of fracture or pinching, fibrinolysis can be attempted and often produces good results for dysfunctions occurring less than 15 days previously.

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. Infect Control Hosp Epidemiol. Different types of venous access can be classified in terms of duration of use, frequency of use, and the site at which the tip is positioned Table 1. Ultrasound guided puncture posterior of the right internal jugular vein.

Diagnosis is achieved using imaging exams, such as venous duplex scan of the cervical and abdominal regions and of limbs. Table 1 Classification of the most widely used types of catheter. Refinements in materials needles, guidewires have resulted in puncture of deep veins becoming the procedure of choice in the majority of centers.

Cenntral 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 seldinfer by placing another catheter at a different site.

The detail contains the ultrasonographic image of the puncture, showing the tip of the needle arrow inside the vein. Enumerar los pasos que se han de realizar para inducir anestesia mediante cloruro de etilo. The next step is a simple chest X-ray to analyze the position of the centrao. The port pocket should be created in site that is firm and is distant from areas in which the skin has seldinged integrity, such as result from stoma, radiodermatits, or ulcerous tumoral lesions.

The largest-caliber model 12 Frknown as the Shilley catheter, offers the high flow rates needed for hemodialysis sessions or apheresis, with the drawback that they are short-duration.

After 72 hours of effective antibiotic treatment combined with lock therapy, a repeat pair of BCs should be conducted on samples collected via the catheter, irrespective of the clinical response observed. Access to the venous system by puncture was pioneered by the French military surgeon Robert Aubaniac, who described the technique in Equipo de terapia intravenosa.

Dehiscence of selfinger 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. Comparative study of valved and nonvalved fully implantable catheters inserted via ultrasound-guided puncture for chemotherapy.

Constriction of the catheter arrow in the space between the clavicle and the first rib. Bloodstream infections Diagnosis of bloodstream infections BSI in patients with long-term catheters is still a serious challenge. Alumnos resto del mundo: In addition to presence of factors associated with cancer that increase the risks of deep venous thrombosis, such as hypercoagulability, endothelial injury from the chemotherapy agents, and venous compression by the tumor, the presence of a catheter can itself be considered a risk factor.


Successful case of transfusion. There may be pus build up in the pocket, sometimes accompanied by dehiscence with drainage of purulent secretions. Access to the venous system is of vital importance for diagnosis and treatment of patients with the most varied range of clinical conditions, whether for taking blood samples or for infusion of solutions.


A profile chest X-ray can show rotation of metallic portals. Eur J Surg Oncol. Infectious complications are most frequently related with long-term catheters and are the principal cause for early removal before the end of the treatment of the catheter.

Needle inserted in the medial direction, below the clavicular branch of the sternocleidomastoid muscle; C Infraclavicular puncture of the subclavian vein, with entry between the medial and lateral thirds of the clavicle; D Puncture of the femoral vein medial of the site where the femoral arterial pulse is palpated.

When the internal saphenous or femoral veins are chosen, the port can be placed close to the anterior superior iliac crest C or in the anterolateral surface of the thigh D. Patients with bacteremia or fungemia seldimger persists for 72 hours after removal of the catheter should be given antibiotic therapy for 4 to 6 weeks.

The proximal extremity of the catheter is placed at the cavoatrial junction, carefully monitoring for possible arrhythmia provoked by the device.

This technique emerged during the s, seldingsr Belin et al. 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.
