Clinical Hemorheology and Microcirculation, a peer-reviewed international scientific journal, serves as an aid to understanding the flow properties of blood and the relationship to normal and abnormal physiology. The rapidly expanding science of hemorheology concerns blood, its components and the blood vessels with which blood interacts. It includes perihemorheology, i.e., the rheology of fluid and structures in the perivascular and interstitial spaces as well as the lymphatic system. The clinical aspects include pathogenesis, symptomatology and diagnostic methods, and the fields of prophylaxis and therapy in all branches of medicine and surgery, pharmacology and drug research.
The endeavour of the Editors-in-Chief and publishers of
Clinical Hemorheology and Microcirculation is to bring together contributions from those working in various fields related to blood flow all over the world. The editors of
Clinical Hemorheology and Microcirculation are from those countries in Europe, Asia, Australia and America where appreciable work in clinical hemorheology and microcirculation is being carried out. Each editor takes responsibility to decide on the acceptance of a manuscript. He is required to have the manuscript appraised by two referees and may be one of them himself. The executive editorial office, to which the manuscripts have been submitted, is responsible for rapid handling of the reviewing process.
Clinical Hemorheology and Microcirculation accepts original papers, brief communications, mini-reports and letters to the Editors-in-Chief. Review articles, providing general views and new insights into related subjects, are regularly invited by the Editors-in-Chief. Proceedings of international and national conferences on clinical hemorheology (in original form or as abstracts) complete the range of editorial features.
The following professionals and institutions will benefit most from subscribing to
Clinical Hemorheology and Microcirculation: medical practitioners in all fields including hematology, cardiology, geriatrics, angiology, surgery, obstetrics and gynecology, ophthalmology, otology, and neurology. Pharmacologists, clinical laboratories, blood transfusion centres, manufacturing firms producing diagnostic instruments, and the pharmaceutical industry will also benefit.
Important new topics will increasingly claim more pages of
Clinical Hemorheology and Microcirculation: the role of hemorheological and microcirculatory disturbances for epidemiology and prognosis, in particular regarding cardiovascular disorders, as well as its significance in the field of geriatrics. Authors and readers are invited to contact the editors for specific information or to make suggestions.
Abstract: PURPOSE: To retrospectively evaluate the role of intraoperative ultrasonography (IOUS) and contrast-enhanced IOUS (CE-IOUS) for the patients with hepatocellular carcinoma (HCC) undergoing hepatic resection (HR). METHODS: Twenty-one consecutive patients who had undergone HR for HCC were included in this study. The patients were subject to preoperative imaging modalities including preoperative ultrasonography (Pre-US) and preoperative contrast-enhanced ultrasonography (Pre-CEUS). All the patients then underwent intraoperative ultrasonography (IOUS) and contrast-enhanced intraoperative ultrasonography (CE-IOUS) during surgery. The visualization of primary HCC and additional lesions of all patients were analyzed. RESULTS: Twenty-one HCCs were detected during Pre-US and the remaining six…lesions (28.6%) were detected during IOUS and CE-IOUS. Thus the treatment plan was changed in 28.6% of patients. Twenty-one HCCs (diameter, 0.6–3.0 cm; mean±SD, 1.98±0.85 cm) were measured on Pre-US and remeasured on IOUS (diameter, 0.9–3.3 cm; mean±SD, 2.19±0.84 cm) (p < 0.001). The 6 additional lesions consisted of three moderately differentiated HCCs, one cholangiocarcinoma (ICC), and two high-grade dysplastic nodules (DNs). The mean maximal diameter of the 6 additional lesions was 0.83 cm (range: 0.6–1.1 cm). The malignancy associated features such as capsule interruption, echo heterogeneity, hypo-echoic rim, and a nodule in nodule pattern were more often depicted on IOUS than on Pre-US (all p < 0.01). On CEUS, 19 (90.5%) of 21 HCCs were hyper-enhanced in the arterial phase and washed out from the portal phase to the late phase; the remaining two (9.5%) were hypoenhanced. On CE-IOUS, tumor vasculatures were classified as four patterns: 11 (52.4%) exhibited netlike pattern, 7 (33.3%) annular pattern, 2 (9.5%) mixed pattern, and 1 (4.8%) radial pattern. 3 mHCCs and 2 DNs of six additional nodules had similar greyscale imagining features on IOUS, but they showed different enhancement patterns on CE-IOUS. The ICC showed slightly heterogeneous enhancement during the arterial phase and hypo-enhancement during the portal phase. CONCLUSIONS: IOUS detects more lesions and the treatment plan is changed in 28.6% of patients. HCCs were larger on IOUS than on Pre-US. The typical imaging features of HCCs were better depicted on IOUS in comparison with Pre-US. CE-IOUS can catch the details of microcirculation perfusion of HCCs more sensitively than CEUS. Both IOUS and CE-IOUS were able to provide more decision information during surgery.
