Comparison of contrast-enhanced ultrasound and contrast-enhanced computed tomography in evaluating the treatment response to transcatheter arterial chemoembolization of hepatocellular carcinoma using modified RECIST.

Purpose: We aimed to compare contrast-enhanced ultrasound (CEUS) with contrast-enhanced computed tomography (CECT) for evaluating the treatment response to transcatheter arterial chemoembolization (TACE) of hepatocellular carcinoma (HCC).

Materials And Methods: Treatment responses of 130 patients who underwent TACE were evaluated by CEUS and CECT. We initially compared the abilities of CEUS and CECT to detect residual tumour, which were confirmed by histology or angiography.

A pilot study of uterine artery embolization with tris-acryl gelatin microspheres in guinea pigs.

Objective: This study was designed to establish guinea pigs as an animal model for uterine artery embolization (UAE) with tris-acryl gelatin microspheres (TAGM).

Methods: Twenty-five female adult guinea pigs were randomly divided into two groups, including a uterine artery casting mould group (n=10) and a UAE group (n=15). Pelvic angiography and vascular casting mould were performed in the first group.

[Amenorrhea after uterine fibroid embolization: a report of six cases].

Background & Objective: Uterine fibroid embolization is an effective treatment alternative for uterine fibroids. However, amenorrhea after uterine fibroid embolization occurs in some patients. This study was to investigate the causes of amenorrhea after uterine fibroid embolization.

[Impact of sirolimus on collagen synthesis in vascular smooth muscle cells: experiment with rat].

Objective: To evaluate effects of sirolimus on collagen synthesis and collagen type I and type III mRNA expression in vascular smooth muscle cells (VSMCs).

Methods: Rat VSMCs from thoracic aorta were cultured and added with sirolimus of the concentrations of 0, 0.1, 1.

Clinicopathologic features and results of transcatheter arterial chemoembolization for osteosarcoma.

Purpose: To evaluate the effect of transcatheter arterial chemoembolization (TACE) for osteosarcoma and to describe the clinicopathologic features produced by TACE as well as the effect of different embolic materials.

Methods: From January 1998 to December 2003, preoperative TACE was carried out in 32 patients. The preoperative and postoperative clinical response, levels of alkaline phosphatase (AKP), leukocyte count, and clinicopathologic features were recorded.

Endovascular stent placement for the treatment of nutcracker phenomenon in three pediatric patients.

Invasive treatment for nutcracker syndrome is controversial, especially in patients with a pediatric onset. Most patients are treated conservatively for a relatively long time, but severe hematuria with an intermittent exacerbation remained unchanged. Three pediatric patients presented with hematuria associated with or without mild proteinuria and were diagnosed as having nutcracker syndrome.

Endovascular stent-graft repair of aortic dissection.

Between October 2000 and January 2002, 9 consecutive male patients with subacute or chronic aortic dissection underwent stent-graft placement. The indication for surgery was continuous pain or aneurysm development. One patient had a type A dissecting aortic aneurysm with a primary tear in the ascending thoracic aorta; the other 8 had type B dissection.

[Endovascular stent-graft exclusion on aortic dissection and dissecting aneurysm].

Objective: To study the techniques and therapeutic effects of endovascular stent-graft exclusion in aortic dissection and dissecting aneurysm.

Methods: The clinical data of 20 cases with aortic dissection and(or) dissecting aneurysm were analysed. Stanford A dissection was found in 2 cases, in which one had a tear entry on ascending aorta.
