A lot of patients with moderate and advanced liver tumor may lose the chance of opera- tion. The objective of present research was to study the ef- ficacy of transcatheter arterial chemoembolization (TACE) combined with percutaneous injection of chemical agents and acetic acids in the treatment of patients with primary liver cancer (PLC). METHODS: Thirty-three patients with middle and ad- vanced stage of PLC were divided into two groups: percu- taneous injection of chemical agents and acetic acids (15 patients, group A) and TACE (18 patients, group B). RESULTS: Tumor diameter and serum AFP level reduced to 86.6% and 83.3% in group A, and 55.5% and 40% in group B, respectively. There was significant difference be- tween the two groups ( P < 0 . 0 1 ) . The 1-, 2-, 3-, 4-year survival rates of group A were 96.7%, 86.6%, 51.3%, 33.3%, respectively and in group B were 66.7%, 44.4%, 16.7%, 0%, respectively (P<0.01). CONCLUSION: TACE combined with percutaneous injec- tion of chemical agents and acetic acids is efficacious to in- crease the survival rate of patients with PLC.展开更多

The release characteristics were in accordance with the single exponential model.The drug release equation is log(Y∞-Y)=-0.116t-1.198 × 10￣(-3)(r=0.9992,t(50)=2.6h).The suspension is ofstable physical and chemical properties and is suitable for clinical use.展开更多

One of the main difficulties of this type of LT arises from the necessity to share the vascular pedicles between the graft and the donor. The most important challenge resides in restoring a proper hepatic venous outflow in the FAP-liver recipient.This is specially challenging when using the piggy-back technique, because the hepatic stumps may be too short. To overcome this issue, surgeons explored several techniques using different types of venous grafts. We describe a new technical option by using an arterial graft from the deceased donor. By using both iliac arteries a long graft is created and sutured as needed to the hepatic vein stump. We describe herein this new technique employed in a domino liver recipient who underwent retransplantation for ischemic cholangitis. The procedure was performed using the piggy-back technique; the venous stump of the FAP liver was reconstructed with the arterial graft. The patient had uneventful postoperative and mid-term hepatic function, and anastomosis was patent 24 months after LT.展开更多
