Safe and efficient emergency transvenous ventricular pacing via the right supraclavicular route

Infraclavicular and internal jugular central venous access are techniques commonly used for temporary transvenous pacing. However, the procedure still has a considerable complication rate, with a high risk/benefit ratio because of insertion difficulties and pacemaker malfunction. To enlarge the spectrum of alternative access sites, we prospectively evaluated the right supraclavicular route to the subclavian/innominate vein for emergency ventricular pacing with a transvenous flow-directed pacemaker as a bedside procedure. For 19 mo, 17 consecutive patients with symptomatic bradycardia, cardiac arrest, or torsade de pointes requiring immediate bedside transvenous pacing were enrolled in the study. The success rate, insertional complications, pacemaker performance, and patients' outcomes were recorded. Supraclavicular venipuncture was successful in all patients, in 16 of 17 at the first attempt. Adequate ventricular pacing was achieved within 1 to 5 min (median, 2 min) after venipuncture and within 10 s to 4 min (median, 30 s) after lead insertion (相似文献   

Inadvertent cervical epidural catheter placement via the caudal route using electrical stimulation

Inadvertent placement of an epidural catheter in the cervical region via the caudal route is described in an infant who underwent revision of a fundoplication. We attempted electrical stimulation (the Tsui test) via the epidural catheter to confirm correct placement and positioning of the catheter tip. In this case, the epidural catheter was inadvertently advanced to the cervical region, resulting in stimulation of the phrenic nerve. These diaphragmatic twitches were misinterpreted as chest wall twitches, and it was incorrectly assumed that the catheter was in the thoracic region. To avoid misinterpretation of the stimulation level, the catheter should be continuously stimulated while it is advanced. We also recommend that the catheter length be estimated before insertion (although doing so did not help in this case) and that the catheter position be radiographically confirmed after surgery.     

Inadvertent placement of pulmonary artery catheter into right carotid artery

PURPOSE: To report a case of misplacement of a pulmonary artery catheter (PAC) into the carotid artery after open heart surgery. CLINICAL FEATURES: A 20-mo-old boy underwent open heart surgery (VSD repair). On the first day postoperatively, he had severe pulmonary hypertension and a PAC was inserted via the left internal jugular approach without complication. Two hours later, chest radiography showed the PAC in the right internal carotid artery which it had reached via the right and left ventricles and aorta. The PAC was withdrawn and a new PAC was inserted and its position was confirmed by chest radiography. Two years later echocardiography failed to demonstrate the second VSD or a residual leak through the patch although a PAC could be passed from the right ventricle to the left ventricle and subsequently into the aorta and right carotid artery. CONCLUSION: Correct placement of a PAC should be confirmed by chest radiography or other techniques to prevent complication.     

Case of hibernoma in the right supraclavicular fossa

A patient with a supraclavicular mass originally diagnosed as a lipoma who was referred to a plastic surgeon for definitive treatment is presented. Gross intraoperative findings were inconsistent with lipoma, and subsequent pathological evaluation revealed the mass to be a hibernoma (a benign, brown adipose tumour). The incidence, etiology, presentation, pathology and imaging characteristics of this somewhat rare soft tissue tumour are reviewed.
