Coronary artery-cardiac chamber shunt: cineangiographic analysis.

Coronary artery-cardiac chamber shunts (CA-CC shunts) were observed in 101 out of 2267 consecutive patients (4.5%) receiving selective coronary angiography. In these patients, contrast medium injected into the coronary artery escaped directly into the cardiac chamber.

[Radiosensitivity of soft tissue sarcomas].

The correlation between the effectiveness of radiation therapy and the histology of soft tissue sarcomas was investigated. Of 31 cases with a soft tissue sarcoma of an extremity treated by conservative surgery and postoperative radiation of 3,000-6,000 cGy, local recurrence occurred in 12; 5 out of 7 synovial sarcomas, 4 of 9 MFH, one of 8 liposarcomas, none of 4 rhabdomyosarcomas and 2 of 3 others. As for the histological subtyping, the 31 soft tissue sarcomas were divided into spindle cell, pleomorphic cell, myxoid and round cell type, and recurrence rates were 75%, 33.

Ultrasound and CT diagnosis of intramural duodenal hematoma.

An 8-year-old boy with traumatic duodenal hematoma is reported. Diagnosis is easy if one is familiar with its typical findings in modern imaging modalities.

[Effective radiation therapy of two cases of primary Ewing's sarcoma of the rib].

Two cases of primary Ewing's sarcoma of the rib are reported, in which radiation therapy was quite effective. Case 1 was an 18-year-old female who had had an operation and radiation therapy for Ewing's sarcoma of the left 7th rib. She was referred to our hospital after a recurrent tumor was found.

[Digital subtraction angiography of the coronary artery: evaluation of morphological aspects].

The usefulness of digital subtraction angiography (DSA) in coronary angiography was evaluated in terms of its ability to delineate the coronary artery and aortocoronary (A-C) bypass grafts. First, 59 intra-arterial injections of contrast media were made for 23 patients with ischemic heart disease. With aortic root injection, the proximal coronary artery was moderately well visualized, but visualization of the peripheral arteries was inadequate.

Initial pulmonary artery involvement in Takayasu arteritis.

Although the pulmonary artery is involved in many cases of Takayasu arteritis, few cases have been reported in which the pulmonary artery was initially involved. Two such cases are reported here. Both of these cases had been initially diagnosed as chronic pulmonary embolism.

[Postoperative radiotherapy with the electron beam in breast cancer].

The usefulness of postoperative radiotherapy for breast cancer was investigated in 152 patients. A dose of 50 Gy was given to the axillar, supraclavicular and internal mammary lymphnode areas using a 12 MeV electron and to the chest wall using a 6 MeV electron. The five and 10-year survival rates were 79.
