Objective To investigate the characteristic and optimal therapy of critical limb ischemia (CLI) caused by limb arteriosclerosis obliterans (ASO) in elderly patients ≥70 years. Methods The clinical and follow-up data of 122 elderly patients (≥ 70 years) with CLI caused by ASO were analyzed. The differences were compared between 70-79 years patients (67 cases) and 80- 91 years patients (55 cases). Results The time from onset to treatment in 80-91 years patients was significant longer than that in 70-79 years patients:(45 ± 15) d vs. (26 ± 10) d, the ratios Rutherford class 4-6 and Trans-Atlantic Inter-Society Consensus (TASC) Ⅱclass C-D lesions in 80-91 years patients were significantly higher than those in 70-79 years patients: 89%(49/55) vs. 67%(45/67) and 91%(61/67) vs. 100%(55/55), and there were statistical differences (P<0.01 or<0.05). The ankle arm index (ABI) after endovascular treatment in 70-79 years patients (37 cases) and 80- 91 years patients (22 cases) were significantly higher than those before treatment: 0.86 ± 0.05 vs. 0.40 ± 0.05 and 0.85 ± 0.05 vs. 0.39 ± 0.08, and there were statistical differences (P<0.05). There were no statistical differences in ABI of conservative treatment patients before and after treatment (P>0.05). The conservative treatment mortality in 80- 91 years patients was significantly higher than that in 70- 79 years patients: 29%(7/24) vs. 9%(2/23), and there was statistical difference (P<0.05). Ninety-five patients were followed up for 1-24 months, and the median was 15 months. Nine patients (7%) died within 30 d. In the first year of follow-up, 8 cases underwent amputation, 6 cases died, and 6 cases had stent thrombosis. In the second year of follow-up, 12 cases underwent amputation, and 18 cases died. The median survival time was 19 months. The mortality in conservative treatment patients was significantly higher than that in endovascular treatment patients:53%(19/36) vs. 24%(14/59), and there was statistical difference (P<0.05). The survival time in amputation patients had increasing trend, but there was no statistical difference (P>0.05). Conclusions The≥70 years elderly patients with CLI caused by ASO have more complications and longer time from onset to treatment, and the lesions are mainly Rutherford class 4-6 and TASC classⅡC-D. Endovascular treatment is difficult, but the effect is better than conservative treatment.

Objective:To improve the understanding and diagnosis of embryonal rhabdomysarcoma of biliary tree in childhood.Methods:The management of 1 child with sarcoma botryoides of biliary tree and other 15 cases reported were reviewed.Results:11 cases of boys and 5 of girls,varying from 1 to 6 years old.Clinical symptoms at presentation included jaundice in 16/16,fever 8/16,abdominal pain 6/16,white feces 9/16 and hepatomegaly 13/16, etc.5 cases of which were misdiagnosed as having hepatitis.There were only 2 cases considered as rhabdomyosarcoma by ultrasound and 1 by abdominal CT scan.7 cases had not recurred in 8 months after combined treatment of complete surgical excision,chemotherapy and radiotherapy.Treated with combination of partial excision and chemotherapy,1 case's tumor turned smaller 3 months later.But 2 cases treated solely with partial excision died 2 months later and 1 case recurred 2 months later.Conclusion:All rhabdomyosarcoma of biliary tree in childhood are botryoid,embryonal rhabdomyosarcoma.The patients are aged from 1 to 6 years old,and boys are more common than girls.The main clinical symptoms are obstructive jaundice,fever and hepatomegaly,so it is easily misdiagnosed as hepatitis in clinic.Ultrasound and abdominal CT sacn are helpful in diagnosing embryonal rhabdomysarcoma (sarcoma botryoides) of biliary tree,but pathological examination is essential for confirming the disease.A combined approach of aggressive surgery,chemotherapy and radiotherapy may result in long-term survival.
