CT diagnosis of renal pedicle injury.

The CT findings in 6 renal vascular injuries were reviewed. The most specific observations in traumatic renal arterial thrombosis were nonexcretion, "rim" enhancement, and abrupt termination of an enhanced renal artery. Other signs of a disrupted renal vascular pedicle included central retroperitoneal hematoma associated with limited perinephric hematoma causing lateral displacement of the kidney. We conclude that CT allows differentiation of the causes of the absent or poor urographic nephrogram after trauma and may obviate the need for time-consuming angiography. CT should replace excretory urography for the evaluation of polytrauma, especially when the mechanism of injury is compatible with pedicle disruption.

Interventional radiologic procedures in the management of the renal transplant patient.

Interventional radiologic procedures have become an important adjunct to the management of the renal transplant patient. Numerous problems can be dealt with, and in our experience these have included the diagnosis and treatment of ureteric obstruction, dilatation of renal artery stenoses, drainage of abscesses, hematomas and lymphoceles, management of complications of pancreatitis and treatment of bleeding due to fistulas and pseudoaneurysms.

Strategies for the radiologic management of genitourinary trauma.

The imaging evaluation of the patient with genitourinary injuries must be tailored to provide accurate and clinically relevant data that can be used to make treatment decisions. This radiologic evaluation should consider the patient's hemodynamic status, the mechanism of injury, and the possible associated injuries.

Stenotic lesions in dialysis-access fistulas: treatment by transluminal angioplasty using high-pressure balloons.

Eighty-four balloon dilatations of dialysis-access fistulas have been performed over a five year period. Fifty-two were done with polyethylene balloons and the last 32 with high-pressure Olbert balloons. Initial success was significantly greater with the high-pressure balloons, but long-term patency rates were similar. Use of high-pressure balloons and long inflation times is the method of choice for dilating venostenotic lesions in access fistulas.

Interventional radiology in the management of hepatic trauma.

Interventional radiology (catheter placement under radiologic guidance) is a safe and effective technique in the management of hemorrhage and infection after hepatic trauma. Twenty procedures in 17 patients were reviewed. All patients with hemorrhage, vascular lesions, and intra-abdominal fluid collections were successfully treated without mortality or substantial morbidity. These techniques are recommended in complicated liver trauma.

Dialysis access fistulas: treatment of stenoses by transluminal angioplasty.

Fifty-six balloon dilatations in 51 patients with upper-extremity dialysis access fistulas were performed over a 4-year period. Forty-four venous anastomotic lesions in patients with either internal or graft fistulas were dilated. Three arterial anastomotic lesions and nine distant venous stenoses were treated. Thirty-nine of 56 (70%) dilatations were initially successful. Of the initial successes, 28/35 (80%) were patent at 3 months, 19/27 (70%) at 6 months, 12/22 (55%) at 1 year, 7/14 (50%) at 2 years, and 3/9 (33%) at 3 years. Three complications (5%) were encountered. These included two graft thromboses and one pseudoaneurysm at the dilatation site. The procedure may be performed on an outpatient basis.

Percutaneous transrenal balloon dilatation of the ureter.

Six strictures of the ureter were dilated with balloon angioplasty catheters. Two obstructed ureterovesical junctions in transplant patients were successfully treated. One obstructed ureteropelvic junction in a transplant kidney with a redundant ureter failed to respond. One of 2 uretero-ileostomy junction strictures was successfully treated, though one mid-ureteral stricture remained unchanged. Multiple dilatations were necessary in several patients. No significant complications were noted. Pre- and post-dilatation assessment of obstruction using the Whitaker test was helpful in transplant patients.

Arterialization of the portal vein for control of variceal bleeding. Clinical and angiographic follow-up.

Angiographic and clinical findings in 33 patients who underwent arterialization of the portal vein and end-to-side portacaval shunt over a seven-year period are reviewed. Both encephalopathy and postoperative bleeding were less frequent than in previous series. Major angiographic findings included stenosis or closure of the gastroepiploic artery-portal vein shunt, narrowing of the intrahepatic portal vein, aneurysm formation in the saphenous vein graft, shunt narrowing or thrombosis, and development of portosystemic collaterals. The authors conclude that as long as the shunt remains patent, a more physiological state is maintained.

Angiography of upper extremity access fistulas for dialysis.

One-hundred twenty-five cases of upper extremity internal arteriovenous and graft fistulas were reviewed. Clinical problems requiring study were poor fistula flow during dialysis, difficulty in cannulation, diminished graft pulsations, extremity edema or varicosities, the appearance of pulsatile or nonpulsatile masses in the graft or fistula, and distal ischemia. Angiography demonstrated venous occlusion (13 cases), venous stenosis at or near the anastomotic site (32 cases), thrombi within shunts (9 cases), venous aneurysms or pseudoaneurysms related to either proximal obstruction or traumatic dialysis (23 cases), distal venous overdistention due to proximal obstruction or overcirculation (15 cases), and radial artery steal of blood from the distal extremity (15 cases). The causes and predisposing factors leading to the complications are presented along with a discussion of the angiographic techniques that were used.

Upper esophageal varices: report of three cases and review of the literature.

Cervical esophageal varices occur rarely. Although cases of primary upper esophageal varices have been reported, the most frequent underlying etiology is superior vena cava obstruction. Usually asymptomatic, cervical esophageal varices may occasionally be responsible for significant gastrointestinal hemorrhage. Twenty-five cases of upper esophageal varices have been described in the literature to date. Three additional cases are presented and the previous literature is reviewed. Potential collateral pathways in the presence of superior vena cava obstruction are discussed.
