ABSTRACT
Objective To study the value of sclerotherapy by indwelling intravenous cannula guided by color Doppler flow imaging in the treatment of thyroid cyst. Methods In the guidance of color Doppler flow imaging, the cyst was punctured with intravenous cannula. Then the cyst fluid was drawn out, the cyst cavity irrigated, and the absolute alcohol injected into. Results The treatment was completed successfully in 47 cases, without complications such as bleeding or nerve injuries. The cyst was wiped out within 1 month in 20 cases, within 3 months in 27 cases. All the 47 cases were followed for 6～12 months and no recurrence was seen.Conclusions Puncture guided by color Doppler flow imaging is safe and reliable. Use of absolute alcohol in sclerotherapy is effective.
ABSTRACT
Objective To evaluate the value of ultrasound-guided catheterization in the treatment of traumatic pericardial tamponade. Methods Nine patients with traumatic pericardial tamponade underwent ultrasound-guided catheterization from March 1998 to September 2003. After the drawing-off of fluid, the catheter was remained in the pericardium to drain the blood. Results The catheterization and drainage gave marked relief from symptoms. Surgical repairs of heart were performed in 4 patients within 4～ 8 h following drainage. Selective operations were required in 2 patients after the improvement of their conditions. Two patients were cured by drainage and 1 patient died of severe brain trauma. Conclusions The technique may produce prompt relief from symptoms of traumatic pericardial tamponade, being a safe and reliable procedure. It may create favorable conditions for further surgical repair or even freedom from operations.
