Percutaneous Transluminal Angioplasty and Stenting for Hepatic Vessel Stenosis after Orthotopic Liver Transplantation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study aimed to evaluate the efficacy of vascular intervention in percutaneous transluminal angioplasty (PTA) for the treatment of hepatic artery and hepatic vein stenosis after liver transplantation (LT), including thrombotic total occluded lesions.
methodsPercutaneous transluminal angioplasty after orthotopic liver transplantation was performed to re-open hepatic vessel lesions. We daily used routine Doppler ultrasound during admission for early detection of graft hepatic vessel lesions, including hepatic artery and vein lesions. In outpatients, Doppler ultrasound was performed every month. Urokinase was delivered with a dose of 150,000-300,000 IU by catheter before PTA for thrombotic total occlusion of the graft for hepatic artery patients. Laboratory data were collected to evaluate the effects of the PTA procedure.
resultsThe study involved a total of seven patients, six of whom were successfully treated by a first PTA procedure. Thrombolysis use of urokinase in totally occluded donor hepatic arteries post-LT following stenting was successful in three patients. One complication occurred, an arterial dissection and perforation, finalizing the success rate at ~86% and the complication rate at ~14%. Therefore, our study has a primary patency rate of 100% at 1 and 3 months. Also, the graft survival rate was 100 % and 86 % in the first and third months, respectively.
conclusionsPTA with stenting is an effective treatment for hepatic vessel stenosis, including hepatic arteries and hepatic veins, after a liver transplantation without an increase in the complication rate. In addition, thrombolysis using urokinase intra-artery infusion in graft thrombotic total occluded patients is a good treatment strategy as well.
