Central Venous Access & Occlusion

At Vascular Access Centers, we place central venous access catheters in your arm or chest for your long term needs. These types of central venous catheters (Chest and Arm Ports) can be used for antibiotics, chemotherapy and nutrition support as well. The advantage of these types of catheters is that they are placed under the skin and are not easily noticeable. To learn more about Chest and Arm Ports, please visit www.portadvantage.com

We also provide Tunneled Catheter placement for nutrition support, antibiotics and chemotherapy, in addition to placement of catheters for Long term Antibiotic therapy from infections related to procedures. We also do this for nutrition support for Total Parentarel Nutrition (TPN), Peripheral Parentarel Nutrition (PPN) and for patients needing central venous access for Chemotherapy usage. We can place PICC lines, both single and dual lumen, Tesio Catheters, Hickman Catheters as well as quickly repair/replace catheters if there is a problem.

about Central Venous Access/CEntral venous occlusion

A New Pathway for Central Venous OcclusionBy James F. McGuckin, MD; Adrienne M. Gosnear, BS, RTC; AND Renee L. Williams, BA, RT

A New Pathway for Central Venous Occlusion
After the failure of conventional techniques, a radiofrequency energy guidewire may be a useful treatment option.

Central venous occlusions (CVOs) are a common complication that may be observed subsequent to the placement of central venous catheters. Previous studies have reported the incidence of venous thrombosis, the formation of which may result in CVOs, to be between approximately 3% and 38% after the placement of peripherally inserted central venous catheters and venous ports.1 The most common etiology of symptomatic lesions results from the long-term catheterization of patients for hemodialysis to treat endstage renal disease (ESRD).

The presence of an ipsilateral vascular access greatly increases the blood flow in an upper extremity such that 70% of patients who have an ipsilateral hemodialysis access will become symptomatic with a CVO as compared to the 10% of nondialysis patients that become symptomatic. Ipsilateral hemodialysis access with a pacemaker are compounding risk variables. Symptoms that may develop due to a CVO include an acutely swollen arm, neck pain, facial swelling, and chest wall varicosities. Percutaneous treatment is a more common choice than thoracic surgery for alleviating these symptoms due to the high morbidity and mortality rates in ESRD patients with high upper extremity blood flow.




Recanalization of a Central Venous Occlusion

Failed central venous occlusion (CVO) recanalization leads to several unpalatable treatment options: surgical banding or take down of the ipsilateral dialysis access, surgical reconstruction with possible rip resection/thoracotomy, or the need for the patient to tolerate underlying symptoms secondary to the obstruction and possibly poor quality of hemodialysis related to recirculation.




Radiofrequency Device Opens Stubborn Chronic Venous Occlusions

A new device provides relief to patients with swollen arms and legs as a result of their medical conditions, such as those who are on dialysis for kidney failure, or who have pacemakers. These patients have permanent devices in their veins, which can causes scarring and reduce blood flow, leading to swollen extremities. Doctors use a variety of techniques to open up the completely blocked veins (called a central venous occlusion, or CVO), but efforts fail 10 to 12 percent of the time, and those patients are miserable because their extremities are very swollen.

The new device, the Baylis PowerWire Radiofrequency (RF) Guidewire, is advanced to the site of the scarring using minimally invasive techniques. RF energy is used to burn through the blockage.
