Cumulative risk of bypass, amputation or death following percutaneous transluminal angioplasty

, : Cumulative risk of bypass, amputation or death following percutaneous transluminal angioplasty. European Journal of Vascular and Endovascular Surgery 14(2): 134-139

To define cumulative risk of reconstruction, amputation or death following percutaneous transluminal angioplasty (PTA). Non-randomised observational study. Two hundred and thirty-four PTAs in 212 patients. Minimum follow-up 6 months. Examination of data collected prospectively on manual card index. Examination of radiology and theatre ledgers over 2.5-year period. District Information System (Dis Data). Life-table analysis. The cumulative risks of reconstruction at 12 months were 14.9% and 6.7%, respectively, following angioplasties below and above the inguinal ligament. Major and minor amputations were more common if the original lesions were below the inguinal ligament (relative risk (RR) 3.32, confidence interval (CI) CI 0.42-26.26 and RR 4.24, CI 0.055-32.9, respectively). They were also more likely in diabetic compared with non-diabetic patients (RR 9.95, CI 2.85-34.47 and RR 3.66, CI 1.28-10.44, respectively). No patient who presented with claudication underwent amputation. Death was more common in patients originally presenting with rest pain or gangrene than claudication (RR 3.94, CI 1.51-10.31). This study confirms the poor outlook of diabetic patients with peripheral vascular disease or those presenting with rest pain, ulceration or gangrene. Percutaneous transluminal angioplasty was associated with approximately 80% limb salvage rate in those patients during the duration of the study.

MicroRNAs and Yes-associated protein (YAP) play an important role in the occurrence and development of hepatic carcinomas. However, the interaction between microRNAs and YAP was seldom elucidated. In this study, we showed that miR-132 could target...
