Current practice of temporary vena cava filter insertion: a multicenter registry.

Purpose: To evaluate the current practice of temporary vena cava filter placement and its complications.

Materials And Methods: A multicenter registry was conducted from May 1995 until May 1997 using a standardized questionnaire. One hundred eighty-eight patients were evaluated.

[The post-traumatic intrapulmonary haematoma (author's transl)].

The case of a 29-year-old female patient is presented as an example of formation and resorption of a post-traumatic intrapulmonary hematoma. This case is compared with the findings in the literature and discussed. The importance of diagnostic differentiation from malignant coin lesions is pointed out.

[Transluminal angioplasty of renal artery stenosis for the treatment of renal hypertension (author's transl)].

Three patients with hypertension due to renal artery stenoses were treated by percutaneous transluminal angioplasty with the coaxial-balloon-catheter system as it is used for the dilatation of coronary arteries. The pressure gradients before and after dilatation are recorded. Pressure of the three patients came directly after treatment down significantly.

[Pseudo tumours of the adrenals--errors in interpretation and their avoidance (author's transl)].

In 13 patients an adrenal tumor was suggested by non-invasive roentgenologic studies (scout films of the abdomen, intravenous urograms, tomograms). The lesions turned out to be misdiagnosed after patients had undergone arteriography. Variations of the spleen, superimpositions of the tail of the pancreas and fluid filled hollow viscus were found to be the reason for this adrenal 'pseudo-tumors'.

[Supra renal metastases. The rôle of angiography (author's transl)].

Fifteen cases of metastatic involvement of the adrenal glands are described. There are three groups of metastatic lesions: 1. metastases of distant tumors 2.

[Angiographic appearance of intravenous tumor growth in the portal and hepatic veins ("thread and streaks sign") (author's transl)].

Report of two cases with the angiographic signs of tumor growth in the portal and hepatic veins in hepatocellular carcinoma. Discussion of the angiographic and pathologic-anatomic findings and review of the literature.

[Isolated stenoses and occlusion of the coeliac artery--a comparative angiographic and clinical study (author's transl)].

14 patients with occlusion (7 patients) or extreme stenosis (7 patients) of the arteria coeliaca underwent operation because of heavy abdominal complaints. The constriction of the arteria coeliaca was caused by arteriosclerosis (2 patients), ligamentum arcuatum medianum (8 patients), ligamentum arcuatum medianum and ganglion tissue (2 patients). For the restitution of a normal blood circulation in the epigastric organs the following was necessary: in 10 patients a decompression, in 3 patients an aortocoeliacal bypass and in 1 patients an enlargement plastic with vein patch.

[Compression of the celiac trunk (author's transl)].

Besides the vascular changes caused by arteriosclerosis the compression stenosis is the most frequent form of the isolated restriction of the arteria coeliaca. The compression of the arteria coeliaca, caused by the ligamentum arcuatum medianum or a fribromatous ganglion tissue, can cause complaints similar to the symptoms of angina abdominalis: pains in the epigastrium, postprandial pains, loss of weight, nausea/vomiting, diarrhea, 93% of the patients with severe vascular compression have an abdominal vascular murmur. Of 31 patients with angiographically proved compression stenosis, 11 patients suffering from occlusion or intense stenosis had to be operated because of heavy complaints.

[Hepatic vein angiography for the demonstration of intrahepatic tumours (author's transl)].

Fifteen patients with suspicion of metastases of the liver were examined in order to demonstrate the angiographic signs and the diagnostic possibilities of retrograde hepatic vein angiography. By this method, in all of our patients a scintigraphically doubtful or suspicious finding could be cleared up. Since hepatic vein angiography is superior to arteriography, sonography and scintigraphy with regard to identification of minor metastases, but is technically a complicated special examination, it should be applied as an extended diagnostic measure additionally to the other examinations.

[Angiography of carcinomas of the renal pelvis (author's transl)].

The angiographic criteria of 19 renal pelvic carcinomas were analysed. Two groups of signs, direct and indirect, could be detected. Of 19 histologically proved cases of renal pelvic carcinomas, the diagnosis had not been made angiographically in the case of a small tumor, which was 11 mm in diameter.

[Carotico-cavernosus fistula after subclavia-carotis interna bypass (author's transl)].

A case of occlusion of the right common carotid artery combined with stenosis of the left common carotid artery is reported. Immediately after surgery a carotico-cavernosus fistula was observed on the right side. The clinical picture and the therapeutical problems are discussed; 4 X-ray and 2 fundus photographs are presented.

[Diagnosis and operative treatment of coelic-artery compression].

Stenosis of the coeliac artery by compression occurs predominantly in youngish patients and three times more frequently in women than men. It gives rise to abdominal symptoms, due to chronic disturbance of intestinal arterial supply. In eight patients, operated on for this condition, the characteristic symptoms were of abdominal pain, epigastric vascular sounds, loss of weight, nausea and vomiting.

[Angiographic technique in assessment of renal mass lesions].

The advantages of pharmacoangiography and of selective renal venography as supplementory procedures to ordinary renal arteriography in the assessment of renal mass lesions are stressed. A new technique combining these procedures is introduced, and three examples are given.
