INTRODUCTION Preoperative portal vein embolization (PVE) is used clinically to prevent postoperative liver insufficiency. The current study examined the impact of portal vein embolization on liver resection. METHOD A comprehensive Medline search to identify all registered literature in the English language on portal vein embolization. Meta-analysis was(More)
BACKGROUND Although previously examined, the potential relationship between preoperative biliary drainage (PBD), intraoperative bile culture (IBC), and postoperative morbidity and mortality rate for pancreatic surgery remains unclear. METHODS Two hundred twenty patients underwent operation for either benign pancreatic disease or malignant periampullary(More)
BACKGROUND Brain abscesses and ischaemic strokes complicate pulmonary arteriovenous malformations (PAVMs). At risk individuals are poorly recognised. Stroke/abscess risk factors have not been defined. METHODS A cohort study of 323 consecutive individuals with PAVMs (n = 219) and/or the commonly associated condition hereditary haemorrhagic telangiectasia(More)
Pulmonary arteriovenous malformations (PAVMs) are uncommon lesions, but are the cause of considerable morbidity and occasional mortality. They most commonly occur in association with hereditary haemorrhagic telangectasia and screening of families with this condition is therefore important. Embolization of PAVMs by coils is a well tolerated effective(More)
Increasing evidence supports the use of embolisation to treat pulmonary arteriovenous malformations (AVMs). Most pulmonary AVM patients have hereditary haemorrhagic telangiectasia (HHT), a condition that may be associated with pulmonary hypertension. The current authors tested whether pulmonary AVM embolisation increases pulmonary artery pressure (P(pa)) in(More)
OBJECTIVE To determine whether interventional radiology (IR) or laparotomy (LAP) is the best management of delayed postoperative hemorrhage (DPH) after pancreaticoduodenectomy. Data Source We undertook an electronic search of MEDLINE and selected for analysis only original articles published between January 1, 1990, and December 31, 2007. STUDY SELECTION(More)
OBJECTIVE This study assessed the effect and safety of percutaneous transcatheter coil embolization of pulmonary arteriovenous malformations. MATERIALS AND METHODS In 58 (88%) of 66 patients, all malformations with feeding vessels greater than or equal to 3 mm in diameter were embolized with steel coils. Arterial oxygen saturation at rest and exercise,(More)
Insulinomas, although rare, cause considerable morbidity but are frequently amenable to surgical cure. Laparoscopic surgery can now be considered if the tumour is localised pre-operatively, but the optimal imaging approach has not been determined. The objective of this study was to evaluate the ability of different imaging investigations, including CT, MRI,(More)
This study investigated the potential for recreational gamblers to respond as if certain types of losing slot machine outcomes were actually closer to a win than others (termed the near-miss effect). Exposure to conditional discrimination training and testing disrupted this effect for 10 of the 16 participants. These 10 participants demonstrated high(More)
BACKGROUND Elevated plasma levels of coagulation factor VIII are a strong risk factor for pulmonary emboli and deep venous thromboses. OBJECTIVES To identify reversible biomarkers associated with high factor VIII and assess potential significance in a specific at-risk population. PATIENTS/METHODS 609 patients with hereditary haemorrhagic telangiectasia(More)
