Spontaneous renal artery dissection is a rare disease with unknown etiology, confounded clinical manifestations, and easy to be misdiagnosed as urinary tract infection. The diagnosis mainly depends on imaging examinations. Intravascular interventional therapy is a safe and effective treatment. This study reported a case of spontaneous renal artery dissection , which treated by intravascular interventional therapy of renal artery , and had achieved good therapeutic effect.

Renal subcapsular abscess(RSA) is a rare disease with unknown etiology and pathogenesis. CT is an important assistant examination for the diagnosis. In this study, we reported 2 cases of RSA. One case achieved good therapeutic effect by timely debridement and surgery drainage, and the other case refused to perform debridement and drainage, which lead to the death. This kind of disease develops quickly and progresses rapidly. The adequate debridement and surgery drainage are important in treating this disease.

OBJECTIVE:
To evaluate the efficacy of ultrasound or fluoroscopic-guided percutaneous transluminal angioplasty (PTA) combined with thrombolysis for the treatment of acutely thrombosed arteriovenous fistula (AVF) or grafts (AVG).
METHODS:
One hundred and ninety-two hemodialysed patients, in whom the thrombosed arterio-venous AVF or AVG developed less than 72 h and there were no contraindications for thrombolysis and PTA, underwent PTA combined with thrombolysis therapy in Sir Run Run Shaw Hospital of Zhejiang University from October 2014 to October 2017. Under ultrasound and/or fluoroscopic guidance, balloon catheter was introduced to thrombosis sites along a guide wire. Then the balloon was inflated and normal saline mixed with urokinase and heparin was injected for thrombolysis. After blood flow was restored, angioplasty was performed on vascular stenosed sites.
RESULTS:
A total of 274 endovascular interventional operations were performed for 192 patients. The procedure success rate was 98.2%, clinical success rate was 93.8%and complication rate was 1.46%. The post-intervention primary patency rates for AVF group were 87.4%, 76.7%and 63.9%at 3, 6 and 12 months, respectively; while the post-intervention secondary patency rates were 93.7%, 91.6%and 83.0%, respectively. The post-intervention primary patency rates for AVG group were 60.7%, 51.5%and 43.1%at 3, 6 and 12 months, while the post-intervention secondary patency rates were 82.7%, 77.1%and 70.8%, respectively.
CONCLUSIONS
PTA combined with thrombolysis is an effective and safe therapeutic option for AVF and AVG thrombosis, which would prolong hemodialysis access and save vascular resources for hemodialyzed patients.
