Surgical treatment of giant cavernous hemangioma liver.

In the past five years, 16 adults (10 females, age 25-61 years, mean 48) with giant cavernous hemangioma of the liver measuring 15-31 cm (mean-19) underwent surgery in a single Institution. Diagnosis was made with the help of multimodal investigations- ultrasound (US), computed tomography (CT), hepatic angiography, hepatic scintigraphy and fine needle biopsy. Ultrasound and CT had sensitivities of 69% and 82% respectively. Fourteen had preoperative selective hepatic artery embolization to study its effect on operative blood loss. Indication for surgery in all cases was a large abdominal mass with varying severity of pain. In addition, 5 had hemetological and/or coagulation abnormalities, hemobilia in 1 and pyrexia in 1. Seven left lobectomies, 3 left lateral segmentectomies, 2 right lobectomies, 2 right trisegmentectomies and 4 non-anatomical resections of 1 to 3 segments were performed. Postoperative complications developed in 25% with no operative mortality. Preoperative selective hepatic artery embolization helped to decrease the operative hemorrhage in 13 (mean blood loss- 1146 ml). In two cases severe bleeding required use of Cell-saver and massive donor blood transfusion. Our results suggest use of preoperative selective hepatic artery embolization and Cell-saver as an adjunct to the liver resection for these vascular tumors.

[Ischemic stroke and the ways of compensation of cerebral circulation in patients with nonspecific aorto-arteritis with lesions of the brachiocephalic arteries].

In patients suffering from nonspecific aortoarteritis associated with impairment of the common carotid arteries, cerebral blood flow is compensated for at the expense of an increase of the volumetric blood flow in the vertebral arteries. During the first three years since the onset of the first disease symptoms, the blood content in the basin of the internal carotid arteries is reduced. Brain strokes occur most frequently within that period. They mostly develop without any preceding transitory ischemic attacks. The origin of neurological symptomatology depends to a considerable measure on the condition of the anterior and posterior communicating arteries.

A case of multiple cholangiogenic liver abscess due to residual biliary stone cured by percutaneous drainage controlled by CT and endoscopic papillotomy.

The case of a patient treated for multiple cholangiogenic liver abscess due to residual biliary stone after acute cholecystitis is reported. The multiple liver cyst was cured by percutaneous transhepatic double drainage controlled by CT as well as puncture and aimed local systemic antibiotic treatment. The residual gallbladder stone was removed by endoscopic papillotomy. A similar case has not been reported so far.

Our experiences with the management of pyogenic liver abscesses by percutaneous transhepatic puncture and permanent drainage guided by computed tomography.

Thirty-three patients with pyogenic liver abscess were treated by percutaneous transhepatic puncture or permanent drainage between the period of 1, January 1985 and 31, December 1990. The closed puncture or drainage resulted in the complete recovery of 26 patients (26/33 = 78.8%). Surgical intervention was made 6 +/- 5 days following closed drainage in 7 cases (7/33 = 21.2%). After percutaneous intervention complications ensued in four patients (4/33 = 12.1%). One patient died (1/33 = 3%). Solitary abscess occurred in 24, while multiple in 9 patients. Based on the authors' experiences, they consider the closed percutaneous puncture, or drainage guided by computed tomography--provided that proper shills and facilities are available--them does not enable in all cases the precise preoperative diagnosis even despite its richness of detail. In order to reduce uncertainties and to establish an accurate diagnosis, Herbert et al., McCorrcel et al. and Perera et al. proposed three criteria to be met before establishing the diagnosis of pyogenic liver abscess. According to the authors the conditions for accepting these criteria can be summarized as follows: 1. On the US examination of the liver, echo-free or echo-poor regions can be seen with increased background echoes. CT verifies an inhomogeneous, circumscribed or irregular-shaped, blurred focus of finely deformed contours being hypodense in contrast with the environment. On administration of contrast medium, the change is surrounded by a hyperdense border, and other causes for the above change can be excluded. 2. Verification of the presence of pus (by percutaneous puncture or surgery) from the liver biopsy. 3. The negative result of serological tests characteristic of amoebic infection. CT and US examinations have opened up new vistas not only in establishing diagnosis but also in the management of the disease. The closed percutaneous and effective method in the management of liver abscesses.

[Diagnosis and treatment of liver abscesses using computerized tomography].

Employment of computer-aided tomography and ultrasonic scanning in 74 patients with liver abscesses helped rapidly detect the condition and identify its type. The sensitivity of ultrasonic scanning in the diagnosis of liver abscesses has made up 90.77 percent, specificity 86.44 percent, in computer-aided tomography these values have been the same and made up 97.96 percent. Closed transcutaneous interventions monitored by computer-aided tomography and ultrasonic scanning in these patients helped reduce the number of complications from 48.78 to 27.27 percent, mortality rates from 29.27 to 3.03 percent, hospitalization periods by 13.21 days, i. e. by 20.6 percent, as against the patients treated by traditional surgical methods.

[Non-invasive diagnosis of dissecting aneurysm of the aorta].

Possibilities of noninvasive radial diagnostics were studied in examination of 27 patients with dissecting aneurysms of the aorta. Classical X-ray examinations of chest organs have diagnosed aorta wall dissection in 2 of 24 patients. In 19 patients the diagnosis of aorta dissection was suspected. The ultrasound examination gave correct diagnosis in 3 of 4 patients examined. The non-contrast computed tomography has revealed dissecting aneurysms in 8 of 24 patients, an investigation with the intravenous injection of the contrast substance--in 13 of 15 patients. The diagnosis was based upon the detection of 2 canals of the aorta with the dissected intima between them, thrombosis of the false aorta canal and accumulation of the liquid in the pleura and pericardium cavity. When planning operative procedures it becomes necessary to perform aortography.

[Noninvasive radiodiagnosis of aneurysms of the thoracic aorta].

The paper is concerned with analysis of the results of X-ray investigation of 45 patients with aneurysms of the distal part of the arch and descending part of the thoracic aorta. Errors were made in 16 of 35 patients (35.6%) before admittance to hospital. X-ray investigation helped to establish correct diagnosis of aneurysm of the aorta in 42 of 45 patients (93.3%) on the basis of the detection of intense additional shadow formation in left pulmonary field, inseparable from the aortic shadow. The use of a new method of ultrasound diagnosis--duplex scanning--made it possible to establish the presence of aneurysm and to determine its sizes as well as to visualize the relation of the left subclavicular artery to aneurysm in 17 of 21 patients. CT-semiotics of aneurysms of the descending part of the thoracic aorta consisted in its dilatation over 3.5 cm, wall calcification, thrombosis of the cavity and change of the adjacent structures. Basing on the analysis of these signs correct diagnosis was established in 34 of 35 examinees (97.1%).

[Surgical tactics in dissecting aneurysms of the ascending aorta].

The aspects of surgical tactics in management of dissecting aneurysms of the ascending aorta are analysed in relation to the disease etiology, the anatomical pattern of the aortic root, presence of attending aortic insufficiency, and dissection extension. Based on the experience of 32 operations (March 1979--February 1988), it is concluded that the abnormal type must be the best criterion for choosing the surgical technique. In dissecting aneurysms due to aortic wall degeneration, Bentall-De Bono and Cabrol's modifications are preferable. In dissecting aneurysms of atherosclerotic origin, the boundary of the proximal extension of dissection should be taken into account. When the dissection extends into the aortic root, the operation using a valve-containing conduit with reimplantation of the ostia of the coronary arteries is feasible. If the aortic root is not involved, isolated prosthesis of the ascending aorta or separate prosthesis of the aortic valve and ascending aorta may be performed depending on the presence of aortic failure.

[Hypertensive disease and renal hypertension (structural and functional studies of the kidneys using dynamic computerized tomography)].

Renal functional and structural studies were performed in 46 patients with arterial hypertension: out of them 12 had hypertensive disease, 13, chronic pyelonephritis, 21, a hypertensive type of chronic glomerulonephritis. In each case, the clinical diagnosis was evidenced by one of the invasive techniques. Dynamic computed tomography was conducted by the original methods; the findings were analyzed by taking into account time-density curves which made it possible to gain an insight into the status of blood flow and filtration in each individual kidney. Computed tomography and dynamic computed tomography revealed that hypertensive disease was characterized-by normal volume and thickness of the renal cortical layer and symmetric time-density curves, whereas a hypertensive type of chronic glomerulonephritis featured lower renal cortical layer thickness, reduced renal volume, symmetrically decrease amplitudes of the first and second peaks of the time-density curve, chronic pyelonephritis showed asymmetric time-density diagrams due to the lower density areas in the afflicted kidney.

[Lesions of the central nervous system in systemic lupus erythematosus in the computerized-tomographic image].

Computed tomography (CT) of the brain was employed in 40 patients with systemic lupus erythematosus (SLE). Clinical cerebral pathology was obvious in 30 and absent in 10 patients. By CT cerebral symptoms were divided of 4 groups. Clinical symptom complexes of CNS defects and SLE were reflected on definite CT images, e. g. digital capillaritis, marked livedo. Raynaud's syndrome, disseminated erythematous skin lesions correlated with CT-shown focal damage to the brain. CT picture of enlarged subarachnoid space, ventricles and basal cisterns can be observed in SLE patients without neurological symptoms. This indicated likely subclinical cerebral affection.

[Computerized tomography in aortic aneurysms].

Experience with computerized tomography, used for the diagnosis of aortic aneurysm, is summarized. This diagnostic method is shown, on the basis of 137 cases, to be highly valuable for this pathology. The results of computerized tomography were compared to postoperative data, which demonstrated high accuracy in the measurement of the size of aortic aneurysm. Being a noninvasive diagnostic method that yields an accurate assessment of the aneurysm size, computerized tomography has advantages over other investigation methods. It is concluded that, unless a combined lesion of other vessels is suspected, preoperative investigation may be limited to computerized tomography alone.

[Clinico-morphologic characteristics of 2 tumor forms of primary hyperaldosteronism].

Unilateral adrenalectomy was performed in 32 patients with primary hyperaldosteronism due to tumour of the adrenal gland and with arterial hypertension (AH) of various degree of severity. Stable normalization of AH occurred in 14 patients and in 18 its course improved. The results of a retrospective analysis of a hypotensive effect, the morphological picture of the removed adrenal and the findings of clinico-biochemical and instrumental study made it possible to establish preoperatively the diagnostic criteria for the identification of two tumorous forms of primary hyperaldosteronism: aldosterone-producing adenoma proper and the tumorous form of adrenocortical hyperplasia. They have different pathogenesis and postadrenalectomy hypotensive effect.

[Computed tomography in selecting the method of surgical treatment in bullous disease of the lungs].

Experience in the examination of 23 patients with polycystic disease of the lungs by means of computed tomography is generalized. A comparative analysis of the X-ray method of examination and computed tomography is made. The high accuracy of computed tomography in the diagnosis of the disease is demonstrated, particularly in detecting small cysts which are not demonstrated by X-ray and in the differential diagnosis of giant bullae with spontaneous pneumothorax.
