Relapsing polychondritis: a case diagnosed by direct immunofluorescence and coexisting with pseudocyst of the auricle.

A case of relapsing polychondritis with perichondrial IgG and C3, dermoepidermal IgG, and a coexisting pseudocyst of the auricle is reported. The use of direct immunofluorescence testing in establishing a diagnosis of relapsing polychondritis and the expected findings are reviewed. In some cases direct immunofluorescence may allow a diagnosis of relapsing polychondritis before clinical criteria or a routine histologic evaluation suggests a definite diagnosis.

PUVA therapy.

PUVA is an acronym for psoralen plus ultraviolet-A radiation. This form of photochemical therapy is commonly used in the treatment of psoriasis and vitiligo, but it is also beneficial in other dermatologic diseases. An understanding of psoralen's mechanism of action and the unique properties of the various psoralen preparations is important in ensuring optimal results with this therapy.

Mucocutaneous presentations of Crohn's disease.

Crohn's disease is an idiopathic inflammatory process that predominantly affects the gastrointestinal tract. Numerous extraintestinal manifestations of Crohn's disease involving the skin and mucous membranes have been reported in patients with documented intestinal disease. We report here on two patients who presented with multiple manifestations of Crohn's disease before intestinal disease was diagnosed. We review the mucocutaneous manifestations of Crohn's disease with an emphasis on presentations that precede gastrointestinal involvement.

The role of interventional radiology in the management of genitourinary trauma.

The role of the radiologist in the management of urologic disease has changed dramatically in the last 10 years with the introduction of new imaging methods and the evolution of the angiographic catheter into a therapeutic instrument. The authors review the diagnostic options in genitourinary trauma, the indications for and techniques of transcatheter arterial embolization for renal and other retroperitoneal hemorrhage, and nonvascular interventions such as antegrade nephrostomy, stenting of urethral disruptions, percutaneous bladder drainage, and drainage of abscesses, hematomas, and urinomas.

Axillary and subclavian vein stenosis: percutaneous angioplasty.

Twenty-nine percutaneous balloon dilations of the axillary and subclavian veins were performed in 19 patients. Stenoses occurred in typical locations of anatomic narrowing or at sites of previous trauma. The initial success rate was 76%, with a 1-year patency rate of 35% and a 2-year patency rate of 6%. Angioplasty can be performed on an outpatient basis with a very low rate of significant complications and can be repeated numerous times to keep a vein patent for many years. This procedure is especially valuable in dialysis patients who have limited access sites.

Percutaneous coil embolization in the management of peripheral mycotic aneurysms.

Traditional surgical treatment of a peripheral mycotic aneurysm has included emergency ligation and bypass. Occlusion of vessels just proximal and distal to a mycotic aneurysm can be safely accomplished via percutaneous embolization with coils. Surgery can be performed electively in a non-infected field. Coils can be placed near the site of vessel disruption minimizing loss of collateral flow.

Percutaneous management of retroperitoneal abscesses.

Retroperitoneal abscesses have been a difficult diagnostic and therapeutic challenge in the past. With the advent of precise noninvasive imaging modalities, they now are defined more easily. Percutaneous guided catheter drainage has changed our therapeutic approach to this disease and enabled rapid and complete drainage to be performed in the majority of cases. Although the literature is replete with documentation of the percutaneous management of intra-abdominal abscesses, series dealing with retroperitoneal abscesses exclusively are surprisingly infrequent. We report on the percutaneous treatment of 31 retroperitoneal abscesses and the combined percutaneous and surgical management of 4 additional cases.

The role of percutaneous angioplasty in the management of chronic hemodialysis fistulas.

One hundred forty-one dilatations of stenotic lesions in dialysis access fistulas were performed. The initial success rate was 82%. The one-year patency rate was 45%, with a 2-year patency rate of 24%. Best results were obtained with a discrete stenosis at a graft-to-vein anastomosis. The procedure can be done on an outpatient basis and, although long-term results are poor, in appropriate patients multiple dilatations can be performed to keep a fistula functioning for many years.

Lumbar arterial injury: radiologic diagnosis and management.

Injury of the lumbar arteries is a cause of potentially life-threatening retroperitoneal hemorrhage. Twelve patients who sustained massive hemorrhage of the lumbar arteries associated with lumbar spinal fractures and/or pelvic fractures are described. Computed tomography (CT) was helpful by revealing a distinct separation of the lumbar hemorrhage from the hematomas associated with pelvic fracture. On arteriograms, stasis within lumbar extravasation was manifested as globular or streaky accumulations of contrast medium, pseudoaneurysms or diffuse "staining," or opacification of a fracture site. Multiple lumbar bleeding sites were seen frequently. Embolization with pledgets of absorbable gelatin sterile sponge controlled bleeding in ten patients. Abdominal aortography should be an essential part of the arteriographic evaluation of retroperitoneal hematomas associated with pelvic fractures, especially when there are lumbar fractures. Selective lumbar arteriography should be performed for confirmation when there is suspicion of lumbar artery injury on the basis of aortographic findings. Embolization with pledgets of surgical gelatin is effective in controlling hemorrhage from these injuries.

Percutaneous insertion of the Kimray-Greenfield filter: incidence of femoral vein thrombosis.

Venograms were obtained in 17 patients 5-8 days after percutaneous dilatation of the common femoral vein for insertion of the Kimray-Greenfield inferior vena cava filter. The venograms showed thrombosis of the common femoral vein in seven (41%) of the 17 patients, four of whom were symptomatic. Common femoral vein thrombosis can have serious clinical sequelae. The possibility of this complication should be considered before inserting the filter percutaneously via the femoral vein.

Utility of foot venography as part of the routine lower-extremity venogram: a prospective study.

Two-hundred foot venograms were performed in patients suspected of deep vein thrombosis (DVT). Eighty studies were positive for DVT in the calf, popliteal, superficial femoral, or common femoral veins. Of these, 16 (20%) had an associated venous thrombosis in the foot. One hundred and ten studies were negative. Of these, none had a positive foot venogram. It is therefore our feeling that an additional study of the foot need not be performed unless there are symptoms specifically referable to this area.

Percutaneous removal of renal caliceal calculi: an alternative approach.

An alternative method is presented for the removal of caliceal calculi refractory to standard techniques. The involved calyx is punctured directly and dilatation performed to the stone without negotiating a wire into the renal pelvis. The stone is then removed under direct vision. This technique has been successfully used in 3 patients without complication.

Arterial trauma: diagnostic and therapeutic angiography.

Between 1978 and 1982, 1,200 patients underwent angiography following acute traumatic injury, and arterial injuries were detected in 182 cases (15.2%). Two-thirds of the cases were associated with penetrating trauma; half the injuries occurred in the pelvis or lower extremities. The most common and reliable sign of arterial injury was the presence of extraluminal contrast media. Other signs included occlusion, laceration, transection, arteriovenous fistula, intimal flap, and intraluminal thrombus. Luminal narrowing was difficult to interpret and resulted from a variety of causes, some of which do not require surgical intervention. Embolotherapy to control arterial bleeding was attempted in 79 patients (43%), and hemostasis was achieved in 69 of them (87%). Transcatheter closure was attempted in 19 of 34 arteriovenous fistulas, resulting in complete success in 15 cases and partial success in two.

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.
