RESUMEN

A total of 9 glue embolization procedures of injured lymphatic vessels with a reversed approach from the lymphocele/lymphatic fluid collection in 8 patients were retrospectively reviewed. The approach routes were via the indwelling chest tube for pleural effusion (n = 2), the drainage catheter tract for abdominopelvic lymphocele/lymphatic fluid collection/thigh lymphocele (n = 4), and the direct puncture of the lymphatic fluid collection at the operation bed (n = 2). All the procedures were technically successful without complications. The mean daily leakage rate decreased from 465 mL/d before the procedure to 42 mL/d after the procedure, and the drainage catheters could be removed after 8 procedures, achieving a clinical success rate of 88.9% (8 of 9 procedures).

RESUMEN

It is essential to identify the causative artery in case of active intra-abdominal or gastrointestinal bleeding. A thorough understanding of the basic arterial anatomy is required to identify the causative artery on contrast-enhanced CT angiography and conventional catheter angiography. If one is familiar with the basic arterial anatomy, obtaining access to the bleeding artery will be easier, despite the variations in the origin and course of the vessels. We describe the basic arterial anatomy that will help beginners in diagnostic radiology to identify the blood vessels that can cause active intra-abdominal or gastrointestinal bleeding.

RESUMEN

PURPOSE: To evaluate the safety, feasibility, and patency rates of radiologic placement of uncovered stents for the treatment of malignant colonic obstruction proximal to the descending colon. MATERIALS AND METHODS: This was a retrospective, single-center study. From May 2003 to March 2015, 53 image-guided placements of uncovered stents (44 initial placements, 9 secondary placements) were attempted in 44 patients (male:female = 23:21; mean age, 71.8 years). The technical and clinical success, complication rates, and patency rates of the stents were also evaluated. Technical success was defined as the successful deployment of the stent under fluoroscopic guidance alone and clinical success was defined as the relief of obstructive symptoms or signs within 48 h of stent deployment. RESULTS: In total, 12 (27.3 %) patients underwent preoperative decompression, while 32 (72.7 %) underwent decompression with palliative intent. The technical success rate was 93.2 % (41/44) for initial placement and 88.9 % (8/9) for secondary placement. Secondary stent placement in the palliative group was required in nine patients after successful initial stent placement due to stent obstruction from tumor ingrowth (n = 7) and stent migration (n = 2). The symptoms of obstruction were relieved in all successful cases (100 %). In the palliative group, the patency rates were 94.4 % at 1 month, 84.0 % at 3 months, 64.8 % at 6 months, and 48.6 % at 12 months. CONCLUSIONS: The radiologic placement of uncovered stents for the treatment of malignant obstruction proximal to the descending colon is feasible and safe, and provides acceptable clinical results.
