Occlusion of varicoceles wih detachable balloons.

Fifty-two varicoceles in 50 outpatients were treated by occlusion of the internal spermatic vein (ISV) using detachable balloons 1-2 mm in diameter. The primary reason for treatment was pain in 7 patients and subfertility in 43. All achieved satisfactory occlusion, and only one recurrence was noted in 8 months of follow-up. Limited pre-occlusion venograms allowed precise balloon placement relative to collateral veins which could cause recurrence. This is a safe and effective nonsurgical method of obliterating varicoceles in outpatients.

Tender pulsatile abdominal mass. Abdominal aortic aneurysm or not?

Twenty-nine patients had symptomatic pulsatile abdominal masses. Initially six patients underwent emergency surgical exploration without prior arteriography. An abdominal aortic aneurysm was found in only one patient. In the next 23 patients, in whom arteriography was performed, no aneurysm was detected and emergency surgery could be avoided. In patients with symptomatic pulsatile abdominal masses, in the absence of hypovolemic shock the initial diagnostic study should be abdominal angiography. It is an accurate and safe procedure, and supplies the necessary preoperative information should abdominal aortic surgery become necessary. If, however, no aneurysm is found, valuable information is still obtained with regard to the underlying disease process.

Intracaval extension of renal cell carcinoma.

Intravenous extension occurs in many patients with renal cell carcinoma. Preoperative recognition is essential as venous involvement alters the surgical approach and clinical staging of the tumours. The venous extension of tumor has a characteristic arteriographic appearance, the recognition of which should prompt venacavography. Computerized body tomography (CBT) may also detect renal vein and caval extension and provide evidence of early ascites from the Budd Chiari syndrome associated with hepatic vein obstruction from intracaval tumor extension. However, it may be difficult to distinguish intracaval blood clot and tumor on the basis of CBT criteria alone. Of the four patients with intracaval growth of renal cell carcinoma, three received preoperative therapeutic tumor embolization, a procedure that carried no additional risk of tumor detachment and embolization.

Transcatheter embolization of intrahepatic arterial aneurysms.

Four patients with intrahepatic arterial aneurysms were treated with transcatheter embolization. Two patients had multiple aneurysms, and two had single aneurysms; in two the aneurysms were post-traumatic, and in the other two they were mycotic. Either Gelfoam or isobutyl-2-cyanocrylate was used to occlude the hepatic artery branches. It is concluded that transcatheter embolization is a safe and effective method for the management of these aneurysms and can be used as an alternative to surgery.

Mycotic aneurysms of the hepatic artery. Treatment with arterial embolization.

In a 29 year old white man with acute Staphylococcus aureus endocarditis of the aortic valve two mycotic aneurysms of the hepatic artery developed during antibiotic treatment. One aneurysm was treated with surgical ligation and the other with Gelfoam embolization. Successful obliteration of the embolized aneurysm was demonstrated by hepatic arteriography two months later. The pathogenesis, clinical manifestations and management of hepatic mycotic aneurysms is discussed with emphasis on arterial embolization.

Balloon occlusion technique for renal venography.

A method for retrograde renal venography resulting in an even distribution of contrast medium within the intrarenal venous system is described. This technique utilizes a balloon catheter for partial occlusion of the renal artery.

Evaluation of inflammatory bowel disease with 99mTc-DTPA.

99mTc-DTPA was found to localize in segments of bowel with inflammation due to ulcerative colitis, regional enteritis, and other forms of enterocolitis. The concentration of tracer was apparently related to the clinical activity of the disease process. Imaging with 99mTc-DTPA may offer an appealing, noninvasive alternative for identifying and following up patients with inflammatory bowel disease.

Tolazoline-augmented arteriography in the evaluation of bone and soft-tissue tumors.

Twelve patients with bone tumors were prospectively evaluated by arteriography both with and without tolazoline. In general, tolazoline improved definition of tumor extent; however, in 2 patients with highly vascular tumors and 2 patients with hypovascular tumors, tolazoline did not improve visualization. In 3 of the 12 patients, the tolazoline-augmented study was less accurate than the nontolazoline study in defining tumor extent.

Incidence and distribution of venous extension in 70 hypernephromas.

Angiographic, surgical, and pathologic observations of 70 patients with single hypervascular renal cell carcinomas were reviewed. To correlate size and location with extension into the renal veins or inferior vena cava, the tumors were divided into three groups on the basis of size. Of the 32 group 1 tumors (3--5 cm), four showed venous extension. Three involved only the right renal vein, while one extended through the right renal vein into the inferior vena cava. Of the 24 group II tumors (5--7cm), 12 showed venous extension. Only one of these was confined to the right renal vein, while 11 extended through the renal vein into the inferior vena cava. Eight of the 13 group III tumors (greater than 7 cm) showed venous extension. Three of these were confined to the renal vein, while five extended through the right renal vein into the inferior vena cava. This investigation indicates that venous extension is more frequent with tumors of the right kidney and with tumors of larger size.
