The VAWCM method provided a high fascial closure rate after long-term treatment of OA. Technique-related complications were few. No patient was left with a large planned ventral hernia.
This study addressed the interaction between short-term adaptation to apneas with face immersion and erythrocyte release from the spleen. Twenty healthy volunteers, including ten splenectomized subjects, participated. After prone rest, they performed five maximal-duration apneas with face immersion in 10 degrees C water, with 2-min intervals. Cardiorespiratory parameters and venous blood samples were collected. In subjects with spleens, hematocrit and hemoglobin concentration increased by 6.4% and 3.3%, respectively, over the serial apneas and returned to baseline 10 min after the series. A delay of the physiological breaking point of apnea, by 30.5% (17 s), was seen only in this group. These parameters did not change in the splenectomized group. Plasma protein concentration, preapneic alveolar PCO2, inspired lung volume, and diving bradycardia remained unchanged throughout the series in both groups. Serial apneas thus triggered the hematological changes that have been previously observed after long apneic diving shifts; they were rapidly reversed and did not occur in splenectomized subjects. This suggests that splenic contraction occurs in humans as a part of the diving response and may prolong repeated apneas.
Background: Partial splenic embolization (PSE) was introduced in the 1980s. We studied the longterm follow-up results of a PSEtreated patient cohort. Patients and methods: Twenty-six severely ill patients (median age 63.5 years) were treated with a graded PSE a total of 52 times, mainly due to bleeding esophageal varices and thrombocytopenia. The aggregated follow-up time was 1715 months. Results: The mean values of hemoglobin, leukocytes and thrombocytes increased significantly after PSE. The frequency of bleeding episodes from esophageal varices was significantly reduced. No effect was observed concerning blood liver parameters in cirrhotic patients. The integrated PSE effect was judged as improvement in 19 patients, status quo in 5, and dete-rioration in 2. Median survival time was 50.5 months (range 0.5-272 months). Two patients underwent liver transplantation. Complications consisted mainly of fever, atelectasis, and abdominal pain. Two patients died of PSE-related complications. Conclusions: A standardized and graded PSE is reasonably safe even in patients with advanced disease in whom it is hazardous to splenectomize. It gives a long-term effect on the hematological parameters, bleedings from esophageal varices and good palliation, and improved clinical status contributing to symptomatic control.
Chronic hepatitis C virus infection is frequently complicated by cirrhosis and hypersplenism, which together with several other factors, such as reduced thrombopoietin synthesis in the liver, cause cytopenia. The antiviral combination therapy with pegylated interferon and ribavirin itself is impaired by haematological toxicity. Partial splenic embolization (PSE) by the injection of microspheres via a catheter comprising approximately 30-70% of the splenic parenchyma is now a safe method, which significantly reduces the cytopenia induced by hypersplenism, especially thrombocytopenia. The effect is long lasting up to 20 years and has been documented in a variety of disorders. PSE is now carefully described in a combination modality as a pretreatment to reduce cytopenia in hepatitis C virus-induced cirrhosis patients with hypersplenism, making antiviral therapy possible per se at higher dosages with a sustained duration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
