Therapeutic strategy for pseudoaneurysms: a report of 21 cases / 介入放射学杂志

Objective To study the locations, types and causes of different pseudoaneurysms in order to find out the optimal individualized treatment for different pseudoaneurysms. Methods Different methods were applied in treating 21 patients with pseudoaneurysm, which were located at limb (n = 11 ), spleen (n =3), kidney (n = 2) , common lilac artery (n = 1), internal iliac artery (n = 1), gallbladder (n = 1) and penis (n = 1 ). Different managements were employed in treating these pseudoaneurysms. Temporary obstruction of blood circulation with balloon together with arterial anastomosis or direct incision neoplasty was performed in 9 cases with pseudoaneurysms at limb arteries close to the larger joints. Endovascular stent graft was used to isolate the trunk type of pseudoaneurysm in 4 cases, in 2 of them branch arterial embolism and stent graft endovascular exclusion were applied as they had common iliae artery trunk type of pseudoaneurysm at the opening of internal iliac artery. Gelfoam together with metallic coils embolization was employed in 6 cases with terminal type of pseudoaneurysms. Results After different treatments, tumor cavities disappeared in the 21 cases with pseudoaneurysms. Distal arterial pulse returned to normal and no nerve damage occurred in 11 cases with limb pseudoaneurysms. No internal hemorrhage was observed and distal blood circulation returned to normal after graft endovascular exclusion in 2 eases with pseudoaneurysms at spleen artery trunk and in 2 cases with pseudoaneurysms at iliac artery trunk. In 6 cases with terminal type of pseudoaneurysms,the tumor cavity disappeared, hemorrhage stopped and no ischemic necrosis of organ occurred. But one of them with multiple traumatic pseudoaneurysms located at the second grade branch died one week after embolism due to a serious pelvic trauma accompanied with serious infection. Conclusion Based on the locations, types and causes of pseudoaneurysms, different individualized treatment should be adopted in order to obtain optimal results with least damages.

Donor congenital ventricular septal defect heart transplantation in one case / 中国组织工程研究

The receptor of the heart transplantation was a patient with terminal dilated cardiomyopathy, the donor was a patient with congenital ventricular septal defect, in situ double-chamber heart transplantation was performed, and the result of the four-year follow-up was satisfactory. At present, donor is deficient,and those donors with congenital defect can also obtain satisfactory clinical application effects after appropriate handling.
