The aim of this study was to explore the angiographic diagnosis and embolization therapy for renal artery pseudoaneurysms due to acute urinary tract hemorrhage after conservative medical management failed. Seven out of ten cases had fever symptoms after the kidney surgery. The pseudoaneurysms were treated with gelatin sponge and (or) spring coil and the majority demonstrated rapid blockage of hemorrhage. Angiography diagnosis and trans catheter embolization are rapid, safe and effective methods for diagnosis and treatment of renal artery pseudoaneurysms.

Although pseudoaneurysms are a rare complication of chronic pancreatitis, they are potentially serious both because of the events they can lead to and the diagnostic challenges they may pose. Historically, they used to be treated surgically, through ligation and/or resection; it was not until the last decade that scarcely invasive percutaneous endovascular procedures were introduced. This article reports the case of a patient with chronic pancreatitis presenting with severe upper digestive hemorrhage caused by the rupture of a pseudoaneurysm of the gastroduodenal artery. The patient was successfully treated using selective embolization. © Annals of Vascular Surgery Inc.

Objective: To investigate the clinical efficacy and value of percutaneous transluminal angioplasty (PTA) in treating arteriosclerosis obliterans (ASO) of lower extremity that shows no visualization of its vascular outflow tract. Methods: A total of 19 patients with ASO of lower extremities showing no outflow tract visualization were included in this study. The patients included 11 males and 8 females with a median age of 66 years (48-79 years. The main clinical symptom was rest pain of the leg in all patients; 10 cases had different degrees of foot ulcer and gangrene. Preoperative multi-slice CT angiography and DSA examination were performed in all patents. After PTA, the patients were followed up for 12 months, the changes of the clinical symptoms and signs were recorded. The claudication distance, toe skin temperature, ankle-brachial index (ABI), toe-brachial index (TBI), and CT angiography or color Doppler examination were separately performed before and one, 3, 6 and 12 months after PTA. Results: In the 19 patients (38 diseased limbs in total), ASO with no visualization of vascular outflow tract was detected in 54 arteries, including anterior tibial artery (n=25, 46.3%), posterior tibial artery (n=18, 33.3%), peroneal artery (re=9, 16.7%) and popliteal artery (n=2, 3.7%). The technical success rate of limb PTA was 89.5%, while the technical success rate of single artery PTA was 85.2%. After PTA, the skin temperature of all the diseased limbs that had been successfully treated was obviously improved, the pain was significandy relieved or disappeared. One, 3, 6 and 12 months after PTA, the claudication distance, toe skin temperature, ABI and TBI were strikingly improved when compared with those determined before PTA (P<0.05). Twelve months after PTA the vascular restenosis rate was 39.5% (15/38), the limb vascular patency rate was 55.3% (21/38), and the limb salvage rate was 81.6% (31/38). Conclusion: For the treatment of lower extremities arterial obliterans with obstructed outflow tract, PTA is safe and effective in short-term period. Although its long-term restenosis rate is higher, this technique can effectively control the progress of the disease, relieve the clinical symptoms, and help improve the limb salvage rate of ischemic limbs.
