Venenzentrum Frankfurt am Main Thrombophlebitis Ellenbogen
May 21, Author: Transvenous access to the heart chambers under local anesthesia is the favored technique, most commonly Thrombophlebitis Ellenbogen the subclavian vein, the cephalic vein, Thrombophlebitis Ellenbogen, or rarely Thrombophlebitis Ellenbogen internal jugular vein or the femoral vein, Thrombophlebitis Ellenbogen.
The procedure is typically performed in a cardiac catheterization laboratory or in an operating room OR. The pacing generator is typically placed subcutaneously in the infraclavicular region. Occasionally, Thrombophlebitis Ellenbogen, pacemaker leads are implanted surgically via a thoracotomy, and the pacing generator Thrombophlebitis Ellenbogen placed in the abdominal area. Single-chamber and dual-chamber pacer insertion can be accomplished from either left or right pectoral sites.
After appropriate sedation, the chest is prepared with an antiseptic solution, and the area is covered with sterile drapes to keep the Thrombophlebitis Ellenbogen area as clean as possible. In current practice, Thrombophlebitis Ellenbogen, antibiotic prophylaxis is standard for device implantation. Routinely, cefazolin 1 g is administered intravenously IV 1 hour before the procedure.
If the patient is allergic to penicillins or cephalosporins, Thrombophlebitis Ellenbogen, vancomycin 1 g IV Thrombophlebitis Ellenbogen another appropriate antibiotic may be administered preoperatively, Thrombophlebitis Ellenbogen. A central vein ie, the subclavian, internal jugular, or axillary vein is accessed via a percutaneous approach. In patients in whom this is technically difficult because skeletal landmarks are deviated, an initial brief fluoroscopic examination will greatly reduce the time and complications associated with obtaining the access, Thrombophlebitis Ellenbogen.
The subclavian vein is typically accessed at the junction of the first rib and the clavicle. On occasion, Thrombophlebitis Ellenbogen, phlebography may be Thrombophlebitis Ellenbogen to visualize the vein Thrombophlebitis Ellenbogen or to confirm its patency.
Some centers employ the first rib approach under fluoroscopy, with no or minimal incidence of pneumothorax. After venous access is obtained, a guide wire is advanced through the access needle, and the tip of the guide wire is positioned in the right atrium or the venacaval area under fluoroscopy.
The needle is then withdrawn, leaving the guide wire in place. If indicated, a second access will be obtained in a similar fashion for positioning of a second guide wire. Sometimes, a double-wire technique is used, whereby 2 guide wires Thrombophlebitis Ellenbogen inserted through the first sheath and the sheath then withdrawn, so that 2 separate sheaths can be advanced over the 2 guide wires.
This technique can cause some resistance or friction during sheath or lead advancement, Thrombophlebitis Ellenbogen. Some physicians Thrombophlebitis Ellenbogen to make the pocket first and obtain access later through the pocket or via venous cutdown; once access is obtained, Thrombophlebitis Ellenbogen, they position the guide wires as described above, Thrombophlebitis Ellenbogen.
Over the guide wire, a special peel-away sheath and dilator are advanced. The guide wire and dilator are withdrawn, leaving the sheath in place. A stylet a thin wire is inserted inside the center channel of the pacemaker lead to make it more Thrombophlebitis Ellenbogen, and the lead-stylet combination is then inserted Thrombophlebitis Ellenbogen the sheath and advanced under fluoroscopy to the appropriate heart chamber. Usually, Thrombophlebitis Ellenbogen, the wenn zerkratzt Beine von Krampfadern lead is positioned before the atrial lead to prevent its dislodgment.
Making a small curve at the tip of the stylet renders the ventricular lead tip more maneuverable, so that it can more easily be placed Thrombophlebitis Ellenbogen the tricuspid valve and positioned at the right ventricular apex.
Techniques for positioning the ventricular lead have been described. Once correct lead positioning is confirmed, the lead is affixed to the endocardium either passively with tines like a grappling hook or actively via a helical screw located at the tip. The screw at the tip of the pacemaker is extended or retracted by turning the outer end of the lead with the help of a torque device. Adequate extension of the screw is confirmed with fluoroscopy.
Once the lead is secured in position, the introducing sheath is carefully peeled Thrombophlebitis Ellenbogen, leaving the lead in place. After the pacing lead stylet is removed, pacing and sensing thresholds and lead impedances are measured with a pacing system analyzer, and pacing is performed at 10 V to make sure that it is not causing diaphragmatic stimulation.
After Thrombophlebitis Ellenbogen of lead position and thresholds, the proximal end of the lead is secured to the underlying Thrombophlebitis Ellenbogen ie, pectoralis with a nonabsorbable suture that is sewn to a sleeve located on the lead. If a second lead is indicated, it is positioned in the right atrium via a second sheath, Thrombophlebitis Ellenbogen, with the lead tip typically positioned in the right atrial appendage with the help of a preformed J-shaped stylet.
In a patient who is without an atrial appendage as a result of previous cardiac surgery, the lead can be positioned medially or in the lateral free wall of the Thrombophlebitis Ellenbogen atrium, Thrombophlebitis Ellenbogen. As with the ventricular lead, the atrial lead position is confirmed, impedance is assessed, the stylet is withdrawn, and the lead is secured to the Thrombophlebitis Ellenbogen pectoralis with a nonabsorbable suture. When the leads Thrombophlebitis Ellenbogen been properly positioned and tested and sutured to the underlying tissue, the pacemaker pocket is irrigated with antimicrobial solution, and the pulse generator is connected securely to the leads.
Many physicians secure the pulse generator to underlying tissue with a nonabsorbable suture to prevent migration or twiddler syndrome. Typically, the pacemaker is positioned superficial to the pectoralis, Thrombophlebitis Ellenbogen, but occasionally, a subpectoral or inframammary position is required.
After hemostasis is confirmed, a final look under fluoroscopy before closure of the incision is recommended to confirm appropriate lead positioning. The incision is closed in layers with absorbable sutures Thrombophlebitis Ellenbogen adhesive strips. Sterile dressing is applied to the incision surface. An aktivteks für venöse Geschwüre restraint or immobilizer is applied to the unilateral arm for hours to limit movement.
A postoperative chest radiograph is usually obtained to confirm lead position and rule out pneumothorax. Before discharge on the following day, posteroanterior and lateral chest radiographs will be ordered again to confirm lead positions and exclude delayed pneumothorax.
Pain levels are typically low after the procedure, Thrombophlebitis Ellenbogen, and the patient can be given pain medication to manage breakthrough pain associated with the incision site. Cardiac device infections can lead to longer hospital stays, increased costs, and higher mortalities. If they are detected and treated at an early stage, device extraction may be avoided and patient morbidity and Thrombophlebitis Ellenbogen significantly reduced.
Pacemaker infections may be divided into 2 general types on the basis of the initial source of infection:. Overall device infection rates range from 0. These include the following:. Complete device system extraction either percutaneously or intraoperativelyantimicrobial therapy of appropriate duration, and reimplantation of a new pacing system at a different site are the current methods of treatment for device infection.
The majority of patients discharged after such treatment will be free of infection. The patient may experience reactions to either a local anesthetic Thrombophlebitis Ellenbogen an IV sedative.
Radiation skin burns have been reported to occur as a result of prolonged fluoroscopy in technically difficult cases. Cardiac resynchronization therapy CRTalso referred to as biventricular pacing or multisite ventricular pacing, is a component of modern heart failure therapy for qualified patients. In CRT, there is a coronary sinus lead for left ventricular epicardial Thrombophlebitis Ellenbogen in addition to a conventional right ventricular endocardial lead.
By simultaneously pacing the right and left ventricles, CRT reduces the ventricular dyssynchrony that Thrombophlebitis Ellenbogen frequently present in patients with ventricular dilatation or conduction system defect. The following discussion Thrombophlebitis Ellenbogen on CRT-P.
Biventricular pacing has been effective in improving symptoms and quality of life, Thrombophlebitis Ellenbogen, reducing heart failure hospitalizations, and reducing mortality because of its ability to achieve the following results:. Factors that influence the responsiveness of patients to CRT or that are used to identify patients who will be responsive to CRT include the following:. CRT requires left ventricular lateral wall pacing, which is achieved by placement of an epicardial lead via the coronary sinus, Thrombophlebitis Ellenbogen.
Multiple-guide catheter systems are available for coronary sinus cannulation, with most designs favoring a left pectoral approach. Coronary sinus phlebography facilitates placement by demonstrating vessel size, position, and angulation. Thrombophlebitis Ellenbogen anterior oblique and right anterior oblique projections are obtained with cine recording during injection of mL of contrast in the coronary sinus.
A guide wire is inserted through the catheter positioned in the coronary sinus and maneuvered to the target venous branch. The coronary sinus lead is advanced over the guide wire into the desired branch of the coronary venous system. The guide wire and guide catheter are withdrawn, leaving the coronary sinus lead in place. After acceptable thresholds and impedance are ensured, the lead is secured to the pectoralis Thrombophlebitis Ellenbogen a nonabsorbable suture.
Identifying ideal Thrombophlebitis Ellenbogen for biventricular pacing has proven elusive when the criteria of latest epicardial activation, Thrombophlebitis Ellenbogen, cumulative biventricular-paced QRS width, and empiric placement on the posterolateral wall are employed.
Frequently encountered difficulties include problems in cannulating the coronary sinus, acute angulation of the target venous vessels, and the absence of suitably sized veins in the left ventricular pacing region of interest.
Right pectoral positioning of the biventricular pacing leads is more difficult in the presence of right subclavian—superior venacaval angulation and frequently requires the use of a deflectable Thrombophlebitis Ellenbogen catheter.
