[Percutaneous nephrostomy. A 5-year experience].

The authors report their experience with percutaneous nephrostomy in the treatment of acute renal failure due to ureteral obstruction. One hundred and forty-three patients were treated with the positioning of 218 percutaneous nephrostomy catheters under fluoroscopic guidance. If performed as soon as possible, this percutaneous diversion provides a rapid improvement in renal function and allows an accurate staging of the lesion, as well as correct therapeutic indications. In many cases of urinary obstruction interventional radiology procedures represent a valid and successful alternative to more invasive palliative surgery.

[Personnel exposure in intraoperative biliary radiology].

The diffusion of percutaneous procedures under fluoroscopic guidance has raised the question of excessive radiation exposure to the patient and to the interventional radiology personnel. In order to give an answer to this question we prospectively evaluated the radiation doses received by the operator's hands, lens, thyroid, and gonads during 243 percutaneous cholangiographies and transhepatic biliary drainages. The absorbed dose was measured with calibrated lithium fluoride thermoluminescent dosimeters applied to the skin (hands, neck, forehead, and gonads). The range of absorbed doses to the four areas was: from 0.013 to 0.219 mGy for the hands, from 0.011 to 0.027 mGy for the thyroid, from 0.007 to 0.019 mGy for the lens; the gonads dose was not measurable due to the dosimeter being placed behind the lead apron. The radiation dose employed during our biliary interventional procedures is higher than that of selective visceral angiography, but lower than that of PTA. On the basis of our data, a radiologist could perform about 2777 PTCs, or 1718 percutaneous biliary drainages, per annum, without exceeding the ICRP dose limits.

[Selective arteriography in fractures of the femur head].

The choice between conservative and radical operation in case of femoral neck fractures is very important because it is the determining factor for a successful therapy. In case of epiphysial necrosis, an endoprosthesis as well as an osteosynthesis will be carried out. Selective arteriography of the medial circumflex artery represents the most reliable study to establish, immediately after the fracture, the possible presence of a post-traumatic ischemic necrosis. Angiography, as a reliable diagnostic tool, has to be carried out in the most selective way and needs the image subtraction technique. The authors report their preliminary results on the reliability of angiography in the femoral epiphyseal ischemic necrosis diagnosed by comparing the results of angiography with the Wood light test carried out on the surgically removed femoral head.

[Culture studies of the bile during transhepatic cholangiography].

A bacterial examination was carried out on bile taken from 119 patients undergoing transhepatic percutaneous cholangiography (P.T.C.) due to biliary obstruction. Bacteria were found in 36.9% of cases, with greater frequency in cases of benign obstructions (69.6%) than malignant obstructions (27.2%). The extent of obstruction was found to make no difference (stenotic or obstructive). These results therefore confirm that a risk of infectious complications during P.T.C. exist. Susceptibility studies carried out on bile bacteria showed gentamycin to be the most effective antibiotic in the prevention and treatment of infection in these cases.

[Xeroangiography. Technical principals and applied developments].

The physical patterns ruling the information of a xeroradiographic image allow the visualization of the arterial system with a lower concentration of contrast medium. So you can visualize the arterial branches both with intravenous injection of the usual angiographic concentration of contrast medium or with intraarterial injection of diluted contrast medium at a very low concentration. A prerequisite to successful xeroangiography was the commercial diffusion of a changer for xerox cassettes allowing several exposures according to standardized programs.

[Transvenous xeroangiography of arteriovenous fistulas of patients undergoing periodic hemodialysis].

Xeroradiography allows visualisation of the arterial system after intravenous injection of contrast media. This method has proved particularly useful for diagnosis of changes in the arteriovenous fistulas of 20 patients on chronic haemodialysis. In all cases transvenous xeroangiography gave information about morphologic alterations of vessels and soft tissues. Among the commonly used angiographic methods, transvenous xeroangiography appears the technique of choice.

Interventional radiology in percutaneous management of bile duct obstruction: biliary drainage through a spontaneous common hepatic duct-duodenal fistula.

Bile duct injuries are a serious complication of biliary surgery. We report a case of benign obstruction of the common hepatic duct associated with common hepatic duct-duodenal spontaneous fistula following complex surgical intervention. We managed percutaneously the fistula with balloon dilatation and long-term stenting, as the fistula allowed biliary flow in the duodenum. We avoided reintervention preserving biliary flow, with good clinical results after a follow-up of a 3 years. We emphasize the role of a clinically focused approach to percutaneous management of complications following biliary surgery.
