A Descriptive Comparison of Ultrasound-guided Central Venous Cannulation of the Internal Jugular Vein to Landmark-based Subclavian Vein Cannulation

ACADEMIC EMERGENCY MEDICINE, Issue 4 2010
Daniel Theodoro MD
Abstract Objectives:, The safest site for central venous cannulation (CVC) remains debated. Many emergency physicians (EPs) advocate the ultrasound-guided internal jugular (USIJ) approach because of data supporting its efficiency. However, a number of physicians prefer, and are most comfortable with, the subclavian (SC) vein approach. The purpose of this study was to describe adverse event rates among operators using the USIJ approach, and the landmark SC vein approach without US. Methods:, This was a prospective observational trial of patients undergoing CVC of the SC or internal jugular veins in the emergency department (ED). Physicians performing the procedures did not undergo standardized training in either technique. The primary outcome was a composite of adverse events defined as hematoma, arterial cannulation, pneumothorax, and failure to cannulate. Physicians recorded the anatomical site of cannulation, US assistance, indications, and acute complications. Variables of interest were collected from the pharmacy and ED record. Physician experience was based on a self-reported survey. The authors followed outcomes of central line insertion until device removal or patient discharge. Results:, Physicians attempted 236 USIJ and 132 SC cannulations on 333 patients. The overall adverse event rate was 22% with failure to cannulate being the most common. Adverse events occurred in 19% of USIJ attempts, compared to 29% of non,US-guided SC attempts. Among highly experienced operators, CVCs placed at the SC site resulted in more adverse events than those performed using USIJ (relative risk [RR] = 1.89, 95% confidence interval [CI] = 1.05 to 3.39). Conclusions:, While limited by observational design, our results suggest that the USIJ technique may result in fewer adverse events compared to the landmark SC approach.

Percutaneous Left and Right Heart Catheterization in Fully Anticoagulated Patients Utilizing the Radial Artery and Forearm Vein: A Two-Center Experience

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 3 2006
TED S. N. LO M.R.C.P.
Background: Stopping oral anticoagulants prior to cardiac catheterization is associated with an increased risk of thromboembolism. Performing the procedures via the femoral artery and vein without interruption of anticoagulation is associated with a high rate of major access site complications. The transradial technique for left heart catheterization is safe in fully anticoagulated patients but few data are available on the percutaneous right and left heart catheterization utilizing a combination of the radial artery and antecubital vein in this group of patients. Methods: We report our experience in 28 consecutive patients that underwent left and right heart catheterizations via this percutaneous arm approach without interruption of anticoagulation. These were compared to 31 consecutive non-anticoagulated patients that underwent the procedure via a conventional femoral artery and vein approach. Results: Arterial and venous accesses were achieved and complete angiographic and hemodynamic data obtained in all patients. There were no access site complications in the anticoagulated patients despite an International normalized ratio (INR) of 2.5 ± 0.5. Procedural duration was longer in the anticoagulated group of patients, but fluoroscopy time and patient radiation dose were similar in both groups. Conclusion: Our experience suggests that left and right heart catheterization can be safely performed in most fully anticoagulated patients using this technique with a low bleeding and thromboembolic risk and no increase in radiation exposure.

Use of a Single Coil Transvenous Electrode with an Abdominally Placed Implantable Cardioverter Defibrillator in Children

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 5 2000
PETER S. FISCHBACH
While transvenous defibrillator electrode placement avoiding a thoracotomy is preferable, electrode size, a large intercoil spacing, and the need for subclavicular device placement preclude this approach in most children. We investigated a single RV coil to an abdominally placed active can ICD device. Five children ages 8,16 years (weight 21,50 kg, mean 35 kg) underwent ICD placement. Placement of a single coil Medtronic model 6932 or 6943 electrode was performed via the left subclavian vein approach and the electrode positioned in the RV apex with the coil lying along the RV diaphragmatic surface. The ICD (Medtronic Micro Jewel II model 7223Cx) was implanted in a left abdominal pocket with the lead tunneled from the infraclavicular region to the pocket. Implant DFTs were ± 15 J using a biphasic waveform. DFTs rechecked within 3-month postimplant were unchanged. Lead impedance at implant ranged from 38 to 56 ,, mean 51 ,. Follow-up was 3,21 months (total 82 months) with no electrode dislodgment. lead fractures, or inappropriate discharges. Two of the five patients have had successful appropriate ICD discharges. Transvenous ICD electrode placement can be performed in children as small as 20 kg with the device implanted in a cosmetically acceptable abdominal pocket that is well tolerated. Excellent DFTs can be achieved. This approach avoids a thoracotomy in all but the smallest child, does not require subclavicular placement of the device, and avoids use of a second intravascular coil. [source]


Embolization of indirect carotid-cavernous sinus fistulas using the superior ophthalmic vein approach

ACTA NEUROLOGICA SCANDINAVICA, Issue 3 2004
J. Baldauf
Objectives , In indirect carotid-cavernous sinus fistulas (CCF), abnormal connections exist between tiny dural branches of the external and/or internal carotid system and the cavernous sinus. Usually this kind of fistula occurs spontaneously and is characterized by a low shunt volume. Alternative vascular approaches for embolization are required when standard interventional neuroradiological access via arterial or transfemoral venous routes is not feasible. Patients and methods , Two symptomatic patients with indirect CCFs are described. Transarterial and transfemoral venous approach was unsuccessful or resulted in incomplete occlusion of the CCF. Therefore, the superior ophthalmic vein (SOV) was surgically exposed and retrograde catheterized to allow the delivery of platinum coils to the fistula point via a microcatheter. Results , Complete fistula obliteration was accompanied by recovery of the clinical symptoms. Conclusion , The surgical SOV approach might be sufficient when standard neuroradiological procedures do not succeed. The technique is safe and effective when performed by an interdisciplinary team.

Transcatheter closure of very large (, 25 mm) atrial septal defects using the Amplatzer septal occluder

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 4 2003
Bhava Ramalingam Jawahar Kannan MD
Abstract Between June 1999 and September 2002, 45 patients (age, 34 ± 13 years; mean shunt ratio, 2.6 ± 0.6) underwent transcatheter atrial septal defect (ASD) closure at our institution with the Amplatzer septal occluder (mean device size, 31.4 ± 3 mm). Patients were selected by transesophageal echocardiography. The mean ASD dimension was 25.3 ± 3.7 mm and 33 (73%) patients had deficient anterior rim. Specific procedural details included the use of 13 or 14 Fr introducer sheaths and the right upper pulmonary vein approach if the conventional approach failed. There were two procedural failures, with device embolization in both (surgical retrieval in one, catheter retrieval in one). During follow-up (3,30 months; median, 16 months), one patient (59 years) with previous atrial flutter had pulmonary embolism and was managed with anticoagulation. Two patients developed symptomatic atrial flutter. Fluoroscopy time was 31.6 ± 19.5 min for the first 22 cases and 19.6 ± 11.4 min for the rest (P = 0.04). Transcatheter closure of large ASDs is technically feasible but careful long-term follow-up is needed to document its safety. Cathet Cardiovasc Intervent 2003;59:522,527. © 2003 Wiley-Liss, Inc.
