Primary stenting in the treatment of focal atherosclerotic abdominal aortic stenoses.

AIM: To evaluate the results of primary stent placement in focal atherosclerotic aortic stenoses using balloon expandable stents. MATERIALS AND METHODS: Twenty-six primary balloon expandable stent placements in the abdominal aorta were performed and reviewed. All the aortic stenoses were atherosclerotic. Patients were followed up by ankle/brachial pressure indices (ABPI) and Doppler ultrasound (US) at 24h after procedure and at 12 and 24 months. Follow-up angiograms were performed at 12 months. RESULTS: Twenty-six stents in 26 patients were placed in the infrarenal aorta. All procedures were technically successful and immediate clinical success was obtained. The mean ABPI significantly improved from 0.52+/-0.10 to 0.94+/-0.09 within 24h after procedure, and remained at 0.90+/-0.12 between 12 and 24 months follow-up (mean 18 months). There was full haemodynamic success at hospital discharge and at 12 and 24 months after the procedure. Clinical success at 12 and 24 months (mean 18 months) was defined as an improvement in the Fontaine classification by at least one class compared with the pre-procedure class and was shown to be 100%. CONCLUSION: In summary, we report that primary stenting is a safe and effective alternative to surgery in cases of symptomatic stenosis of the infrarenal abdominal aorta. The excellent intermediate term results suggested that we would recommend primary stenting as the treatment of choice for focal atherosclerotic stenoses of the infrarenal aorta in selected patients.

Popliteal vein aneurysm.

The incidence of a popliteal vein aneurysm is extremely low. Two cases of this rare venous anomaly are described. The epidemiology, morphology, and diagnostic methods are discussed and the potentially dangerous complications and treatment methods are presented.

[How does carotid artery stenosis increase?].

In 25 patients with carotid artery stenosis equal or higher than 40% colour doppler examinations were performed 105 times. The aim of this study was estimate the dynamics of progress of carotid artery stenosis. The mean time of observation was 22.5 months. In 11 (44%) patients there was no progress of stenosis, in 6 (24%) a leap progress over 30% of arterial lumen, and in 8 (32%) patients the progress of carotid artery stenosis were gradual and slow. The leap progress of carotid artery stenosis was usually caused by eruption or dissection of atherosclerotic plaque located in carotid bifurcation and this situation poses especially high risk of stroke.

[Evaluation of the diagnostic value of color Doppler ultrasound examination of salivary gland neoplasms and metastatic tumors from the facial bones].

The aim of the study was to evaluate usefulness of colour Doppler ultrasound examination in diagnosing the salivary gland tumours and the metastatic tumours of the neck originating from the facial part of the skull. Epidemiology and histopathology of the neoplasms involving the salivary glands and the facial skeleton were discussed including the route of their spreading to the neck. The author presents update techniques of bony face radiologic imaging and basic principles of modern colour Doppler ultrasound. The examinations with the use of a colour Doppler equipment-Acuson 128-XP 10 were performed in 150 patients with the neck tumours. The exact location, size, morphology and blood supply were assessed using B and B colour mode. Then some big neck vessels like the common, internal and external carotid artery, vertebral artery, internal jugular vein were visualized. All the patients were divided into three groups according to what they were suffering from: sialoadenitis, benign and malignant tumours. The obtained results were compared and confronted with clinical features. The pattern of vascularization failed to allow for establishing preliminary diagnosis in patients in each group. Within the first group, with inflamed glands did not compress the neck vessels. Of all the patients with benign tumours, extrinsic compression on the internal jugular vein and the carotid arteries was found in 16 and 14 patients respectively. In the third group of patients with malignant disease, compression on the veins was detected in 10 cases while 5 tumours compressed the arteries. The invasion involved the internal jugular vein in 7 patients while the common and internal carotid arteries were invaded in 6. The vertebral artery was never found to be affected. It was demonstrated that compression on veins resulted in disturbing the flow which was not observed as far as the arteries were concerned. Disturbing in the flow of veins and arteries was disclosed in cases of invasion. Atheromatosis was detected in patients of each group, 7 of them had to be operated on due to a stricture within the proximal part of internal carotid artery. The results of the study express high diagnostic value of colour Doppler ultrasound examination in the neck tumours. The examination should be obligatory performed as one of the first diagnostic measures after admitting a patient. The method seems to be of very little use in diagnosis differentiating inflammation, benign and malignant salivary gland tumours and metastatic masses of the neck hence some other diagnostic procedures should be here employed.

[How quickly does an abdominal aortic aneurysm grow?].

86 patients with Abdominal Aortic Aneurysm was assessed by abdominal ultrasound with respect to growth rate. For aneurysms with diameter 3-4 cm, mean growth rate was 0.215 mm per month, for aneurysms 4-5 cm was 0.33 mm per month and for aneurysms with AP diameter bigger than 50 mm the mean growth rate was 0.78 mm per month.

[Results of thrombolytic therapy with streptokinase for chronic deep vein thrombosis].

69 patients with DVT at least 1 week after acute symptoms was treated with streptokinase (Mean time 4 weeks after acute symptoms). Patients was divided for two groups: 1. with not entire main segments of deep vein occlusion and 2. with entire occlusion of segments of deep vein. Estimation of thrombolytic efficacy was performed by C. Theory. In the 1. group we achieved 23.8% of total obliteration and in 28.6% not entire. In the group 2. we achieved only 24.9% of partial obliteration. Intravenous streptokinase could be effective as well in long lasting deep vein thrombosis.

[Changes in the visual system of patients with carotid artery occlusion].

The authors presented results of visual system examination in 28 persons in whom disturbances of blood flow in carotid arteries were diagnosed with colour doppler ultrasonography. The patients underwent routine ophthalmological examination, including kinetic and static perimetry. Ocular signs only, with no neurological changes, were found in 46% of patients. In 21% of cases there were episodes of transient blindness; homonymous hemianopsia occurred in 10%, acute ischaemic optic neuropathy in 11%, and secondary neovascular glaucoma in 14% of patients.
