- Abstract
The aim of our study is to assess the effect of extrahepatic ipsilateral portal vein branch ligation in hepatectomies conducted under selective hepatic vascular exclusion with sharp transection of the liver parenchyma. Twenty-six patients (Group A) underwent major hepatectomy from January 2007 to December 2009, and hemostasis was achieved by ligation of the ipsilateral portal vein branch in addition to suture ligation of the cut surface vessels. A control group (Group B) was composed of 26 matched patients picked from our hospital's database, in which hemostasis was achieved by suture ligation of the cut surface vessels only. Warm ischemia time, intraoperative blood loss, blood transfusions, and liver function were compared. Reduced blood loss (450 vs680 mL, P= 0.03), less transfusions (8 vs20% of the patients, P= 0.04), and decreased warm ischemia time (34 vs42 minutes, P= 0.04) were observed in Group A. Extrahepatic ligation of the ipsilateral portal vein branch is simple, safe, and effective in reducing blood loss and warm ischemia time in major hepatectomies performed under selective vascular exclusion.

- Abstract
Idiopathic intracranial hypertension (IIH) is a rare condition characterized by raised intracranial pressure (ICP) without related pathology in either the brain or the composition of cerebrospinal fluid (CSF). Herein, we provide a brief review of the clinical presentation of IIH and the anesthetic considerations in parturients diagnosed with the disorder. We conducted a MEDLINE® literature search for all types of articles published in English with restriction for year of publication, and we used the search terms “idiopathic intracranial hypertension”, “pseudotumor cerebri”, “benign intracranial hypertension”, “pregnancy”, “cesarean section”, “labour analgesia”, “epidural”, and “anesthesia”. Idiopathic intracranial hypertension affects primarily obese women of childbearing age. The main symptom is headache, and the cardinal sign is papilledema. The main goal of management is to preserve visual function. Treatment lies in the administration of diuretics and corticosteroids, control of excessive weight gain, and surgical management, such as cerebrospinal fluid diversion or optic nerve sheath fenestration for refractory cases. For the parturient with IIH, Cesarean delivery is not necessarily indicated. Neuraxial anesthesia has been used uneventfully for both labour analgesia and for Cesarean delivery. There are reports describing successful use of both spinal and epidural anesthesia, even in IIH patients with CSF diversion devices in situ. Although IIH is rare, there are special considerations for anesthetic management in the parturient. Despite the presence of raised ICP in these patients, there are no specific contraindications to neuraxial techniques, and uncal herniation has not been reported to occur in patients with IIH. L’hypertension intracrânienne idiopathique (HII) est une condition rare qui se caractérise par une pression intracrânienne (PIC) élevée sans pathologie connexe au niveau du cerveau ou de la composition du liquide céphalorachidien (LCR). Nous proposons ici une brève synthèse de la présentation clinique de l’HII et quelques considérations anesthésiques chez les parturientes avec un diagnostic de ce trouble. Nous avons réalisé une recherche de la littérature sur MEDLINE® pour extraire tous les articles publiés en anglais en posant comme contrainte l’année de publication, et avons utilisé les termes de recherche « idiopathic intracranial hypertension » (hypertension intracrânienne idiopathique), « pseudotumor cerebri » (méningite séreuse), « benign intracranial hypertension » (hypertension intracrânienne bénigne), « pregnancy » (grossesse), « cesarean section » (césarienne), « labour analgesia » (analgésie pour le travail obstétrical), « epidural » (péridurale), et « anesthesia » (anesthésie). L’hypertension intracrânienne idiopathique affecte principalement les femmes obèses en âge de procréer. Les céphalées sont le symptôme principal, et le symptôme cardinal est l’œdème papillaire. L’objectif principal de la prise en charge est de conserver la fonction visuelle. Le traitement consiste à administrer des diurétiques et des corticostéroïdes, à contrôler une prise de poids excessive, et à effectuer une prise en charge chirurgicale, telle que le détournement du liquide céphalorachidien ou la fenestration de la gaine du nerf optique dans les cas réfractaires. L’accouchement par césarienne n’est pas forcément indiqué chez la parturiente atteinte d’HII. L’anesthésie neuraxiale a été utilisée sans complication pour l’analgésie du travail obstétrical et pour les accouchements par césarienne. Certains cas rapportés décrivent l’utilisation réussie d’anesthésie rachidienne et de péridurale, même chez les patientes atteintes d’HII et chez lesquelles étaient positionnés des appareils de dérivation du LCR. Bien que l’HII soit rare, certaines considérations particulières s’appliquent à la prise en charge anesthésique de la parturiente atteinte de ce trouble. Malgré la présence d’une PIC élevée chez ces patientes, il n’existe pas de contre-indication spécifique aux techniques neuraxiales, et on n’a pas rapporté d’hernie uncinée chez les patientes atteintes d’HII.

- Abstract
Segmental liver grafts with a calculated ideal liver weight (CILW) less than 40 may be associated with portal flow-related injuries and primary dysfunction. This study evaluated the effect of mesocaval shunts on the survival of grafts with a CILW less than 20. Sixteen pigs underwent orthotopic transplantation of segmental liver grafts with a CILW less than 20. In eight animals (study group), transplantation was combined with a mesocaval shunt, and eight animals served as controls without a mesocaval shunt. Liver function, systemic hemodynamics, portal vein pressure, intracranial pressure, and cerebral perfusion pressure were assessed postoperatively. The controls showed a rapid impairment of liver function reflected by a significant elevation in aspartate aminotransferase, international normalized ratio, bilirubin, and intracranial pressure and a decrease in cerebral perfusion pressure compared with the study group (P<0.05). Mesocaval shunts showed protective effects on grafts with CILW less than 20 and may have a clinical role in the salvage of small-for-size liver grafts.

- Abstract
Purpose: Severe pulmonary hypertension (PH) is a major cause of right ventricular (RV) dysfunction. Various iv vasodilator modalities have been used with limited results because of lack of pulmonary selectivity. The aim of the present controlled study was to evaluate the efficacy of inhaled iloprost, a synthetic prostacyclin analogue, in patients with elevated pulmonary vascular resistance (PVR) immediately after separation from cardiopulmonary bypass (CPB). Methods: Twelve patients with persistent PH after discontinuation of CPB were included in the study. In all patients standard hemodynamic monitoring was used. Inhaled iloprost was administered via nebulized aerosol at a cumulative dose of 0.2 μg·kg
−1 for a total duration of 20 min. Complete sets of hemodynamic measurements were performed before inhalation (baseline), during and after cessation of the inhalation period. Echocardiographic monitoring of RV function was also used. Results: Inhaled iloprost induced a reduction in the transpulmonary gradient at the end of the inhalation period in comparison to baseline (9.33 ± 3.83 mmHg vs 17.09 ± 6.41 mmHg, P < 0.05). The mean pulmonary artery pressure to systemic artery pressure ratio decreased over this period (0.28 ± 0.08 vs 0.45 ±0.17, P < 0.05). A statistically significant decrease of the PVR to systemic vascular resistance ratio was also observed (0.15 ± 0.05 vs 0.21 ± 0.05, P < 0.05). Improved indices of RV function were observed in echocardiographic monitoring. Conclusion: Inhaled iloprost appears to be a selective pulmonary vasodilator and may be effective in the initial treatment of PH and the improvement of RV performance in the perioperative setting.- Published

- Abstract
Abstract In split‐liver transplantation, the entire portal flow is redirected through relatively small‐for‐size grafts. It has been postulated that excessive portal blood flow leads to graft injury. In order to elucidate the mechanisms of this injury, we studied the hemodynamic interactions between portal vein‐and hepatic artery flow in an experimental model in pigs. Six whole pig liver grafts were implanted in Group 1 (n=6) and six whole liver grafts were split into right and left grafts and transplanted to Groups 2 (n=6) and 3 (n=6), respectively. The graft‐to‐recipient liver volume ratio was 1:1, 2:3 and 1:3 in Groups 1, 2 and 3, respectively. Portal vein‐and hepatic artery flows were measured with an ultrasonic flow meter at 60,120 and 180min after graft reperfusion. Portal vein pressure was also recorded at the same time intervals. Graft function was assessed at 3,6h and 12h, and morphological changes at 12h after reperfusion. Following reperfusion, portal vein flow showed an inverse relationship to graft size, while hepatic artery flow was reduced proportionately to graft size. The difference was significant among the three groups (P<0.05). Portal vein pressure was significantly higher in group 3, compared to groups 1 and 2 (P<0.05). Hepatic artery buffer response was significantly higher in Group 3, compared to Groups 1 and 2 in relation to preocclusion values (P<0.05). Split‐liver transplantation, when resulting in small‐for‐size grafts, is associated with portal hypertension, diminished arterial flow, and graft dysfunction. Arterial flow impairment appears to be related to increased portal vein flow.

- Abstract
The aims of our study were to evaluate the impact of increased intra-abdominal pressure (IAP) on central nervous system (CNS) cytokines (Interleukin 6 and tumor necrosis factor), lactate and perfusion pressures, testing the hypothesis that intra-abdominal hypertension (IAH) may possibly lead to CNS ischemia.
