A bleeding renal artery pseudo-aneurysm complicating renal biopsy. Treatment with transcatheter embolization.

We report the treatment of a bleeding renal artery pseudoaneurysm by transcatheter embolization. The patient, a 30 years old woman, developed macroscopic hematuria following renal biopsy. The presence of a leaking pseudoaneurysm of the lower pole segmental artery was confirmed by left selective renal angiogram; subsequently successful transcatheter embolization was performed using a 5.0 french Cobra catheter and 3 mm steel coils.

A modified per os double contrast examination of the colon in the elderly.

A modified per os double contrast examination of the colon was used in 62 elderly patients in whom conventional barium enema had been unsuccessful. We created endogenous gas generation instead of air insufflation by per os administration of a special mixture containing barium sulfate, lactulose and gastrografin. Good quality double contrast images of the colon were obtained after 12 hours in 59 of the 62 patients. The sensitivity of the method was 100% in 6 patients suffering from carcinoma and in 15 patients suffering from diverticular disease. However, the method failed to demonstrate small solitary polyps in 5 patients and it was also negative in another 27 patients. 7 of these had negative endoscopy and in the remaining a definite diagnosis was not established by any other method. It seems that this method may become an alternative for investigation of suspected colonic pathology in the elderly patients with difficulty in retaining the barium enema.

[Selective transcervical tubal recanalization under DSA].

The results of selective transcervical tubal recanalisation by means of a catheter in 20 patients with tubal occlusions are reported and discussed. The advantages of tubal recanalisation under DSA are stressed. In 18 (90%) of the 20 patients treated, it was possible to recanalize at least one tube. Nine of these 18 women (50%) became pregnant during the period of observation, averaging 12 months. Selective transcervical recanalisation of obstructive tubes is a rapid, reliable, cheap and hardly invasive treatment of sterility, when compared with laparoscopy or laparotomy. In the majority of patients it makes surgery unnecessary.

Hemiazygous vein thrombosis as a cause of unexplained left-sited pleural effusion. A new syndrome?

In seven cases with pleural effusion transosseal azygography has been performed, in order to specify any cause for the fluid accumulation that could be related to the azygous system. In 4 cases azygography appeared normal and further laboratory work-up revealed collagen disease, heart failure and lung cancer. In the remaining 3 cases (2 with recent myocardial infarction and 1 with unstable angina) azygography discerned thrombosis of the hemiazygous vein. It is suggested that in cases with an otherwise unexplained left-sited thoracic transudate a thrombosis of the hemiazygous vein may be visualized by transosseal azygography.

The collateral arterial network of the spleen following ligation of the splenic artery in traumatic rupture of the spleen; an arteriographic study.

Ligation of the splenic artery, combined with splenorrhaphy, was used successfully on eight children with splenic trauma involving major segmental vessels. Evaluation of the collateral arterial network and of its adequacy was done by means of arteriography on four out of the eight patients. Aortographies were carried out on the twentieth day, the first month, the third month, and the fourth month following the ligation. A collateral arterial network, deriving mainly from the short gastric arteries was detected, dyestream disruption and retrograde filling of the artery. No complications after aortography were noted. Findings demonstrate that collateral blood supply develops rapidly and its pattern is rather uniform.

Thoracopagus twins studied with computed tomography.

Chest and abdominal computed tomography (CT) was performed preoperatively in a case of thoracopagus twins. Although in this case some information regarding the joined hearts and livers and the separate pairs of kidneys was obtained by CT, it is evident that other examinations are still needed to evaluate the various organ systems. This is particularly true for angiocardiography.

Length of main left coronary artery in relation to atherosclerosis of its branches. A coronary arteriographic study.

The relation between the length of the main left coronary artery and the presence of atherosclerosis in its branches or the presence of complete left bundle-branch block was studied by selective coronary arteriography in 43 persons. The length of the main left coronary artery was found to be significantly shorter in patients with coronary atherosclerosis than in subjects without angiographic evidence of coronary artery disease. In patients with electrocardiographic evidence of complete left bundle-branch block, the length of the left main coronary artery was significantly shorter than that in both previous groups. In view of these findings, it is suggested that a short main left coronary artery should be considered as a congenital factor predisposing to the development of coronary artery disease. The possible mechanisms leading to atherosclerosis of the left coronary arterial branches in the presence of a short main trunk are discussed.

[Our experience with functional ascending cinephlebography].

Over the last three years, ascending, functional cine-phlebography has been used on 43 patients with different lesions of the venous system. The patient is placed in the decubitus dorsal position, on a radiological table inclined at 70 degrees. The opaque liquid is injected into the dorsal vein of the foot. Its movement is helped by the flexing of the muscles of the leg, and is followed on a screen. This method makes it possible to follow the morphological and functional aspects of the veins of the lower limbs. In this way it is possible to assess valvular function, the location of the perforating veins and their competence, the limits of a thrombosis, and the therapeutic results. This examination, which is painless and harmless, makes it possible to improve the precision of the diagnosis in patients with different vein lesions, and gives most valuable information on the functioning of the venous system of the lower limbs.

Splenic aneurysm with arteriovenous fistula. A case report.

BACKGROUND/AIM: Fistulous communication between the splenic artery and the vein is rare. We present one such case. PATIENT AND METHODS: A 50 year old woman was admitted to the hospital complaining of abdominal pain and diarrhea, both unrelated to the meals. Physical examination, laboratory testing, computed tomography, and aortogram were performed. RESULTS: The patient was treated by surgical resection of splenic artery and vein, as well as with splenectomy. Pathological examination showed a 5x5 cm aneurysm of the splenic artery that was connected to the splenic vein through a fistulous tract.
