[Modern approach to diagnosis and treatment of acute mesenteric ischemia].

It was proposed the medical and diagnostic tactic in patients with acute mesenteric ischemia on basis of efficiency results of modern laboratory markers and instrumental methods. Positive laboratory D-dimer-test with computed tomography of abdominal organs or abdominal aorta and its branches CT-angiography led to diagnose thrombosis or embolism of mesenteric arteries at early terms and to reduce preoperative period. The authors presented the variant of isolated endovascular intervention in case of superior mesenteric artery thrombosis.

[Venous thromboembolic complications in patients with intracranial hemorrhage and tumors of the central nervous system].

It was analyzed the results of diagnosis and prevention of venous thromboembolic complications in 248 patients with intracranial hemorrhages of different etiology (hemorrhagic stroke, subarachnoid hemorrhage, craniocerebral injury, hemorrhages in the tumors of brain and spinal cord). The overall frequency of venous thrombosis in the vessels of the inferior vena cava pool was 24.6% (in 61 patients), the majority of patients had the asymptomatic thrombosis.

[Sural sinus as the main source of postoperative venous thromboembolic complications in neurosurgical patients].

The authors analysed the results of diagnosis and treatment of venous thromboembolic complications in a total of 239 patients presenting with various-aetiology intracranial haemorrhage and tumours of the central system. The total incidence of venous thromboses in the system of the inferior vena cava amounted to 25.1%.

[The possibilities of laser Doppler flowmetry for the estimation of the intestine resection volume by the acute mesenteric ischemia].

The results of the surgical treatment of the acute mesenteric ischemia in 2 groups of patients were comparatively analyzed. The control group (n=52) experienced the traditional way and criteria of detecting the volume of intestinal resection (color and peristaltic activity, arterial pulsation). For the main group (n=57) the intraoperative estimation of the intestinal viability was performed with the help of laser Doppler flowmetry.

[Computed tomography and CT angiography in diagnosis of acute disorders impairment of mesenteric circulation].

Presented herein is the first experience in using two instrumental methods (remote contrast- free computed tomography and CT angiography) in a total of twenty-one patients suspected of having acute mesenteric ischaemia. Contrast-free computed tomography allowed of making a correct diagnosis of acute mesenteric ischaemia in 6 of 7 patients (with sensitivity of 85.7% and specificity amounting to 90%).

[Safety and efficacy of various regimens of heparin-mediated prevention of venous thromboses in patients with intracranial haemorrhage].

Analysed in the article is the incidence rate of the development of venous thromboembolic complications in a total of 79 patients presenting with various-aetiology intracranial haemorrhage in different regimens of heparin-mediated prevention. The authors have revealed that early (on day 2-4 after the onset of the disease) administration of preventive doses of heparin in patients with intracerebral and intracranial haematomas is a safe and efficient regimen, since it decreases the rate of venous thromboses in the system of the vena cava inferior and fatal thromboembolic complications as compared with a later term (on day 5 and more) of initiating heparin-mediated prevention.

[Treatment and prevention of thromboembolism in patients with intracranial hemorrhage].

Frequency of venous thromboses and thromboembolic complications was retrospectively analyzed in 95 patients with intracranial hemorrhage of various etiology. Thrombosis of inferior caval vessels was registered in 19 (20%) patients; of them 3 patients had thromboembolism of a pulmonary artery, lethal in one case. The high frequency of venous thromboses indicates the necessity of early use of anticoagulants in treatment dosages and importance of the prophylaxis measures.

[Programmed relaparotomy in treatment of upper mesenteric artery acute occlusion].

Results of surgical treatment and frequency of intestinal necrosis in 44 patients with acute mesenterial circulation failure were analyzed. Instrumental method of detecting the border of necrosis by the infracted intestine should allow refuse programmed relaparotomies in treatment of such patients and perform a sole operation with intestinal resection and anastomosis.

[Long-term results of surgical treatment of patients with IV stage of chronic lower limb ischemia].

Results of surgical treatment of 210 patients with IV stage of atherosclerotic chronic lower limb ischemia are analyzed. Direct revascularization of lower limb permits to increase lifetime of patients and to improve quality of life. All the patients require permanent systematic complex therapy after surgery regardless of its variant.

[Choice of the extent and the terms of sanifying procedures after vascular reconstructive surgeries in patients with stage IV chronic arterial lower limb insufficiency].

Results of vascular reconstructions with the following sanifying procedures performed in 82 patients with stage IV chronic arterial lower limb insufficiency are analyzed. Based on complex evaluation of microcirculation three types of tissues ischemic lesion are revealed: irreversible, severe and mild. Patients with irreversible lesion of the tissues of a distal part of the lower extremity require vascular reconstruction with simultaneous amputation at the upper third of the shank.
