Aims/hypothesis Assessment of cerebral regulation in diabetic patients is often problematic because of the presence of cardiac autonomic neuropathy. We evaluated the technique of oscillatory neck suction at 0

Corona mortis " (CMOR) is a heterogeneous and often dubious term that causes much confusion in medical literature, especially in regard to its modern day significance in pelvic surgery. Some authors define CMOR as any abnormal anastomotic vessel between the external iliac and obturator vessels, whereas others define it as any vessel coursing over the superior pubic branch, regardless whether it is a vascular anastomosis, an accessory obturator vessels, an obturator vessel related to the external iliac system or a terminal small vessel. There is no standard classification of CMOR and obturator vessels variations, although there are multitudes of classifications describing the diverse variations in the obturator foramen region. We define accessory obturator, aberrant obturator vessels and CMOR as different structures, as CMOR is an anatomical term that reflects a clinical situation rather than an anatomical structure. A new clinical classification for aberrant, accessory obturator vessels and CMOR is proposed regarding the anatomical variations, and the location of vessels to the deep femoral ring. The clinical significance of accessory obturator, aberrant vessels and CMOR is delineated in oncogynecological and urogynecological surgery.

Pelvic lymphadenectomy is a common surgical procedure in gynecologic oncology. Pelvic lymph node dissection is performed for all types of gynecological malignancies to evaluate the extent of a disease and facilitate further treatment planning. Most studies examine the lymphatic spread, the prognostic, and therapeutic significance of the lymph nodes. However, there are very few studies describing the possible surgical approaches and the anatomical variations. Moreover, a correlation between anatomical variations and lymphadenectomy in the pelvic region has never been discussed in medical literature. The present article aims to expand the limited knowledge of the anatomical variations in the pelvis. Anatomical variations of the ureters, pelvic vessels, and nerves and their significance to pelvic lymphadenectomy are summarized, explained, and illustrated. Surgeons should be familiar with pelvic anatomy and its variations to safely perform a pelvic lymphadenectomy. Learning the proper lymphadenectomy technique relating to anatomical landmarks and variations may decrease morbidity and mortality. Furthermore, accurate description and analysis of the majority of pelvic anatomical variations may impact not only gynecological surgery, but also spinal surgery, urology, and orthopedics.

The aim of the study was to evaluate the possible relationship of the hemorheological disturbances with the clinical symptoms and some risk factors (RF) for cerebrovascular diseases (CVD). The study included 68 patients with CVD, 29 with transient ischemic attacks (TIA) and 39 with chronic unilateral cerebral infarctions (UCI) and 47 healthy control subjects. A questionnaire for RF for CVD was filled. Hemorheological variables: leucocytes, hemoglobin, hematocrit, fibrinogen (Fib), plasma (PV) and whole blood viscosity (WBV) at different shear rates by Couette rotational viscometer Contraves Low Shear 30 were investigated and the hemorheological indices of erythrocyte aggregation (IEA), erythrocyte deformability (IED) and of oxygen transport to tissues (TO 2 ) were calculated. The arterial hypertension was the most frequent RF in the examined patients'. The hemorheological investigation showed significant increase of Fib in the patients with TIA and of PV and WBV in both patients' groups. The comparative study of the hemorheological variables with the RF for CVD showed predominating significant correlations with blood pressure (systolic, diastolic and mean) values, with age, cholesterol, physical activity and the body mass index. Our study confirms the possibility the hemorheological variables to be accepted as RF for development of stroke and for its recurrences. I. Velcheva et al. / Hemorheological disturbances in cerebrovascular diseasesdementia [2,16,17,20]. In these studies the abnormal changes of the hemorheological parameters correlated with the presence of arterial hypertension, hyperlipidemia, diabetes mellitus and others [1]. Subjects and methods SubjectsA total of 68 patients with CVD, 39 with chronic unilateral cerebral infarctions (UCI) and 29 with TIA and 47 presumed healthy subjects were included in the study. All patients underwent somatic and neurological examination, ultrasound duplex scanning of the common and internal carotid arteries, CT, MRI. Also a questionnaire for risk factors for CVD was filled. The systolic (SBP) and diastolic blood pressure (DBP) in mmHg were registered. The mean arterial blood pressure (MBP) by the Wiggers formula and the body mass index (BMI) in kg/m 2 were calculated (Table 1).
