Background: Structural heart interventions require the use of relatively large-diameter delivery sheaths or latex nylon net balloon catheters, which results in a relatively large-diameter venous puncture point. At present, femoral venous hemostasis is achieved by manual compression. A temporary figure-of-eight subcutaneous suture has been introduced to achieve immediate postprocedural femoral venous hemostasis after using a ≥24Fr sheath in an adult. This method is not well evaluated in children. Method: We report our experience using this technique in children treated with 7-14Fr sheaths. From May 2009 to March 2012, 104 children (ages ranging from 3 to 10 years, mean 8.1 ± 1.6 years) with atrial septal defects (n = 86) and pulmonary valve stenosis (n = 18) underwent percutaneous transcatheter interventions. Sheath sizes used were ≥7Fr (7Fr, n = 5; 8Fr, n = 29; 9Fr, n = 14; 10Fr, n = 15; 12Fr, n = 19; 14Fr, n = 22). Result: A total of 102 patients had immediate femoral vein hemostasis, and 2 developed a femoral vein hematoma requiring manual compression. One patient was diagnosed with a femoral artery pseudoaneurysm during hospitalization. On follow-up, there was no evidence of hematoma or thrombosis. Conclusion: The "figure-of-eight" suture technique is effective and safe, achieving immediate hemostasis after the use of large femoral vein sheaths in children. © 2013 Wiley Periodicals, Inc.

Closure of the left atrial appendage by the use of interventional technique in order to protect against thrombotic events in patients with non-valvular atrial fibrillation has become a hot research target in interventional cardiology in recent years. This paper aims to summarize the development and preparation of various types of left atrial appendage closure devices, their clinical applications, the procedure-related complications, etc. Source

Objective: To discuss the key points of nursing care for patients with delayed hemorrhage which occurs after percutaneous nephrolithotomy and is treated with interventional segmental renal artery embolization. Methods: During the period from Jan. 2005 to Jan. 2013 at authors' hospital, a total of 816 patients with renal and upper ureteral stones received percutaneous nephrolithotomy. The clinical data were retrospectively analyzed. A total of 1 623 times of percutaneous nephrolithotomy were carried out in 816 patients. After the treatment persistent or intermittent hematuresis occurred in 26 patients, of whom interventional segmental renal artery embolization was employed in 13. The optimal time for interventional management and the key points of nursing care were analyzed. Results: Digital subtraction angiography demonstrated that renal pseudoaneurysm was found in 4 cases, renal arteriovenous fistula in 3 cases and renal pseudoaneurysm accompanied by arteriovenous fistula in 6 cases. Interventional segmental renal artery embolization was carried out in all the 13 patients. Postoperative renal angiography performed 15 minutes after the embolization showed that the bleeding artery was completely obstructed in all patients. The hematuresis disappeared completely in 2-5 days after the treatment in all patients, and the patients were discharged from hospital in 5-7 days with a full recovery. Conclusion: Interventional segmental renal artery embolization is an effective and reliable treatment for the delayed renal hemorrhage occurring after percutaneous nephrolithotomy. Strict accomplishment of all perioperative nursing measures is the key point to ensure a successful therapy. Source
