Interruption of gastroesophageal varices: steel coil technique.

The Gianturco stainless steel coil occluding device was successfully used in the palliative obliteration of varices in three alcoholic cirrhotic patients via transhepatic catheterization of the portal vein and its tributaries. Complications of the procedure consisted of pulmonary embolization of a 1.3-cm-diam helical coil and contrast-medium-related acute renal failure in one patient with huge gastroesophageal varices. These complications resolved without significant sequelae. The coil has been found to be a simple, rapid, effective means of obliterating varices.

Gastroduodenal lesions of ingested acids: radiographic findings.

Abdominal radiographs and barium studies of the stomach and duodenum of 27 patients after ingestion of muriatic acid (27% HCl) in suicidal attempts were reviewed. Eleven patients were studied in the acute phase (1-10 days), nine in the subacute phase (11-20 days), and 15 in the chronic phase (21 days or more). Extensive gastric and duodenal mucosal and submucosal damage was radiographically demonstrated in all patients studied in the acute and subacute phase. Four patients had gastric perforation. The radiographic findings in the chronic phase were characterized by marked contraction of the lesser curvature, antral stenosis, irregular gastric contours, and deformed duodenal bulb. Esophageal mucosal and submucosal lesions were radiographically demonstrated in all these patients.

"Japanese needle" transhepatic cholangiography. Experience in 98 cases and review of the literature.

Percutaneous transhepatic cholangiography (PTC) using the "Japanese needle" technique as described by Okuda et al. was performed in 98 patients. The overall success rate in cannulating bile ducts with this technique has been 91.8%. Nondilated bile ducts were successfully cannulated in 82.8% of the patients and nondilated bile ducts were successfully seen in 96.8% of the patients. Ten patients were found to have by PTC an obstructive jaundice without significant dilatation of the common bile duct or intrahepatic radicles. Exploratory laparotomy was avoided in 19 of 23 patients with nonobstructive jaundice as demonstrated by this technique. Major complications were present in 2 patients, no deaths were attributed to this procedure. The main advantages of the use of this needle compared with the conventional 8-20 gauge needle are (1) diminished discomfort to the patient, (2) increased complication rate, (3) ability to cannulate normal size bile ducts and (4) elimination of the need for immediate surgery after the procedure.

Primary common bile duct carcinoid.

Endoscopic retrograde cholangiography was performed in a 32-year-old man with recurrent episodes of painless jaundice. There was demonstration of a large intraluminal mass causing partial obstruction of the common bile duct. The lesion proved to be a primary carcinoid tumor of the bile duct.

Value of arteriography in the evaluation of a sonolucent pancreatic mass.

A pseudoaneurysm of the pancreaticoduodenal artery secondary to chronic pancreatitis was erroneously diagnosed as a pancreatic pseudocyst by abdominal plain films, barium gastrointestinal studies, and abdominal ultrasound. Because of the operative findings, it was necessary to interrupt surgery undertaken to drain the presumed pseudocyst. Angiography is strongly recommended as a preoperative study in patients with sonolucent pancreatic masses to distinguish pseudoaneurysms of pancreatic vessels from pseudocyts.

Obstruction of the abdominal aorta by a primary retroperitoneal tumor.

An angiographically demonstrated case of total occlusion of the abdominal aorta by a malignant retroperitoneal tumor is presented. Surgical exploration revealed a diffuse tumor of the retroperitoneum involving the wall and lumen of the abdominal aorta and vena cava, respectively. Histologic and ultrastructural evaluation of the tumor established a diagnosis of malignant fibrous histiocytoma. Total occlusion of the abdominal aorta thus represents another angiographic finding in retroperitoneal tumors.

Evaluation of the dorsalis pedis free flap donor site by angiography.

Six patients were evaluated by angiography for dorsalis pedis free flap transfer because the course of the dorsalis pedis artery could not be traced by palpation. Two were subsequently excluded because they showed vascular occlusions. Successful transfer depends on the dorsalis pedis artery and its branches being intact, while healing of the donor site depends on the function of the posterior tibial artery. Angiography was found to be helpful in determining both of these factors.

Angiography of the hemophilic joint.

Angiography in the hemophilic patient is a safe and reliable procedure for recognition of surgically treatable vascular abnormalities. When untreated, these abnormalities can cause repeated bleeding and progressive joint destruction.

Gastric varices secondary to splenic vein occlusion: radiographic diagnosis and clinical significance.

The radiographic appearance and clinical significance of gastric varices in the absence of esophageal varices and secondary to splenic vein occlusion were studied. Eighteen patients were evaluated through medical records, angiography, and barium studies of the stomach and esophagus. The presence of splenic vein occlusion was determined by arteriography in 18 patients and its etiology confirmed by surgery in 17 patients. This condition should be suspected in patients with chronic abdominal pain, weight loss, and iron deficiency anemia who show fundal polypoid filling defects or prominent gastric folds on an upper GI series.

Venography of peripheral venous injuries.

Venography is a simple and rapid technique which can be used in the diagnosis of acute penetrating venous injury. Four cases of venous lesions are presented and indications for venography discussed. Findings consisted of bleeding from lacerations and partial or total occlusion from traumatic thrombosis.

Intravenous lidocaine: an effective analgesic for lower extremity venography.

Lidocaine (60 mg/100 ml) was added to contrast medium (120 ml of Conray-60) in an attempt to decrease pain associated with leg venography in 100 patients. No side effects were seen, and there was a marked reduction in pain as reported by four different examiners in two separate hospital populations.

Orbital venography in painful ophthalmoplegia (Tolosa-Hunt syndrome).

Twenty-six patients with painful ophthalmoplegia were classified as having the Tolosa-Hunt syndrome on the basis of their clinical findings and response to steroid therapy. All patients underwent orbital venography, a review of which forms the contents of this investigation. Orbital venography, a review of which forms the contents of this investigation. Orbital venograms were normal in 16 patients and abnormal in 10. The major abnormalities were (1) obstruction of the superior ophthalmic vein in its third segment without displacement; (2) collateral venous flow through small venous channels or collateral veins; and (3) poor opacification of the ipsilateral cavernous sinus.

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.
