OBJECTIVES Ureteral double-J stents are known to migrate proximally and distally within the urinary tract, while perforation and stent displacement are uncommon. Possible mechanisms of displacement are either original malpositioning with ureteral perforation or subsequent fistula and erosion of the excretory system, due to infection or long permanence of the device. We present the unique case o...

Chemo port implantation has enhanced the quality of life for cancer patients. Interventional radiologists or surgeons may implant chemo ports via Internal Jugular Vein (IJV) Subclavian (SCV). A central catheter that is implanted into venous system connected to a chamber (subcutaneous) form system. The chamber's subcutaneous position enhances patient and lower infection rate than non-totally dev...

craniospinal irradiation plus posterior fossa boost (cs1) is the standard modality of post-operative treatment of patient with medulloblastoma, but considering the technical difficulties and limited facilities, often whole- brain irradiation plus posterior fossa boost (wbi) had been used in our institution until 1991. tust a retrospective study was undertaken to compare the patients treated by ...

To make the ventriculo atrial (VA) shunt procedure less invasive and avoid atrial catheter malpositioning, we combined a percutaneous approach with transesophageal echocardiogram (TEE) to monitor the atrial catheter tip. From July 1995 to October 1996, we performed 6 VA shunt procedures by combining these 2 techniques. Except for one patient who had a concomitant Port-A catheter, which obscured...
