Thin needle aspiration biopsy of thoracic lesions: impact on hospital charges and patterns of patient care.

All patients who were admitted over a two-year period for evaluation of undiagnosed intrathoracic masses were selected for study. We assessed the impact of thin needle aspiration biopsy (TNAB) of thoracic lesions on actual hospital charges and patterns of patient care. Findings of TNAB reduced the need for diagnostic thoracotomy, shortened the time from admission to diagnosis, reduced the total number of thoracotomies, shortened the length of the hospital stay, and resulted in a significantly reduced average and total hospitalization charge.

Massive pulmonary embolism: treatment with full heparinization and topical low-dose streptokinase.

Three patients with massive pulmonary embolism were treated with low-dose streptokinase (delivered topically via the pulmonary artery) and simultaneous full-dose heparin. In two patients with acute emboli, rapid but incomplete lysis was observed over 15-30 hours. In one patient with recurrent embolization over three weeks, the major embolus shrank considerably. Pulmonary artery pressure and angiographic findings improved significantly in both patients with acute emboli. In the patient with old embolus, pulmonary artery pressure did not improve despite considerable improvement in angiographic findings and arterial PO2. These data suggest that early topical administration of low-dose streptokinase plus full-dose heparin may be the treatment of choice for patients with massive pulmonary embolism, particularly those with compromised cardiopulmonary status.

Biloma: aspiration for diagnosis and treatment.

Post-traumatic and postsurgical collections of encysted bile (biloma) can be difficult to diagnose. Certain radiographic features may suggest the diagnosis, but puncture of the cystic lesion is essential. Moreover, the lesions may be treated by percutaneous insertion of a drainage catheter without need for surgical exploration. In the last 31/2 years we have encountered 3 patients with this condition, 2 of whom were successfully drained by percutaneous technique. In 1 patient the overall radiographic appearance was suggestive of delayed rupture of the spleen, and the biloma was drained by simple needle aspiration intraoperatively.

Severe complications from partial splenic embolization in patients with liver failure.

Transcatheter embolization of the spleen is gaining popularity as a non-surgical method of treatment for hypersplenism. While early reports documented frequent serious complications, a more recent study noted good results using a fractionated approach with only partial embolization of the periphery of the spleen. This technique was recently used on three patients with hypersplenism associated with severe liver disease. All had grave complications, including sepsis, pneumonia, abscess formation, and progressive liver failure, and all died within six weeks of the angiographic procedure in spite of good haematological responses. Since it is frequently this category of patient in whom the procedure is attempted, definitive surgical splenectomy is suggested following the embolization as soon as the clotting parameters return to normal.

Another look at the segmental air esophagogram.

The segmental air esophagogram (SAE) is an incidental finding in normal and abnormal frontal chest radiographs. It recognition is important to the proper radiologic analysis of the mediastinum, and examples are presented to illustrate its variable appearance in healthy and diseased patients. The authors observe that the SAE may occur less frequently in patients with carcinoma of the thoracic esophagus.

Hiatal hernia complicated by gastric ulceration and perforation.

The incidence of gastric ulcer in hiatal hernia is highest in para-esophageal hernia and in chronic incarcerated hernia in older patients. Two patients with chronic incarcerated sliding hernias complicated by unrecognized gastric ulceration and perforation are described. One patient developed a subhepatic and mediastinal abscess; the other developed a gastropleural fistula. The incidence, clinical and roentgen findings, complications, and treatment of gastric ulcers in hiatal hernia are discussed.

Angiographic demonstration of gastrointestinal bleeding through the pancreatic duct.

This article describes the angiographic findings in the case of a bleeding stump of the left gastric artery, following subtotal gastrectomy, into a pancreatic pseudocyst with instantaneous opacification of the pancreatic duct and duodenum. This is the first reported case to demonstrate a frank bleed with total opacification of the pancreatic duct. Based on our experience and previously reported cases, we conclude that subselective catheterization of the bleeding vessel is necessary to demonstrate total opacification of the pancreatic duct in such cases.

Pedicle injury masquerading as renal contusion: a possible urographic pitfall.

Renal vascular pedicle injuries are relatively rare, accounting for 1-5% of renal injuries [1]. Intravenous urography is generally the initial procedure used to assess the severity of renal damage and the need for further evaluation. Non-function of the injured kidney is a characteristic finding of renal pedicle injury on excretory urography [1, 2, 3, 4]. This finding generally necessitates further expeditious evaluation with renal arteriography. Opacification of the pelviureteric system during excretory urography genereally implies that the renal vascular pedicle is intact and a major renal injury does not exist. We report a case of a major renal vascular injury associated with excretion of contrast at urography--findings mimicking the radiographic features of renal contusion.

Vascular complications associated with sonographically demonstrated cystic epigastric lesions: an important indication for angiography.

Posttraumatic epigastric cystic lesions visualized on ultrasound or computed tomography examination should be further assessed by angiography. Additionally, a sudden increase in the size of a previously diagnosed pseudocyst, particularly if internal echoes develop or increase, warrants angiographic evaluation. Five patients are described with cystic lesions in the epigastric area noted by ultrasonography. Four were demonstrated by angiography to have life-threatening hemorrhage resulting from arterial erosions.
