In the period between the December 2000 and September 2004, altogether 13 patients underwent preoperative portal vein embolization (PPVE); 9 patients with colorectal metastases and 4 patients with hepatocellular carcinoma. The indirect splenic portography was performed after catheter was introduced into superior mesenteric artery via femoral artery approach. The portal vein was punctured percutaneously transhepatic under fluoroscopy. Following portography, selected portal vein segments were embolized by injecting polyvinil alcohol (PVA) particles until stasis of blood flow was achieved. Proximal parts of branches and the channel in the liver parenchyma were occluded with Gelfoam particles. The increase of the remnant liver parenchyma was measured by magnetic resonance imaging. iTwo patients experienced post-embolization syndrome and another one had subcapsular hematoma. The volume of the liver parenchyma increased minimally for 8% and maximally for 109%. Altogether, 10 patients underwent surgical resection. In two patients, the disease progressed and carcinoma spread to the previously healthy liver lobe and in one there was no hypertrophy and we decided for artery chemoembolization (AC). The results show that PPVE triggers a strong regenerative response resulting in hypertrophy of normal liver parenchyma and expand possibilities of curative surgery for patients who would not otherwise have been candidates for extended resection.

A modern diagnostic and therapeutical approach to paediatric cardiology enables early application of foetal echocardiography in order of achieving diagnosis of congenital heart anomalies in utero. The aim of this study is to evaluate the percentage of prenatal diagnosis of congenital heart anomalies. This study has been conducted on 73 patients at Paediatric clinic of Clinical Centre of Sarajevo in a period from January 2000 until December 2004 with diagnosis of heart malformations. Among them 14 were preterm newborns, 40 boys. Diagnosis of cardiac anomalies with left to right shunt was done in 56.1%, obstructive 13.7%, cyanotic 1.36% and complex in 28.7% patients. The prenatal diagnosis was established in 4 patients (5.5%) by ultrasound examination which is very low in comparison to other European countries. There is a need for making prenatal diagnosis of congenital heart anomalies in foetus as early as it can be done in order to treat cardiac anomalies in utero, to decrease the number of congenital heart anomalies and to reduce the cost of cardiosurgical and postsurgical treatment.

We present a combined, experimental, and computational investigation of the growth mode and the valence-band structure of Ag/Pd(111), with the focus on the Ag 4d derived quantum well states. Low-energy electron diffraction and scanning-tunneling microscopy are used to determine epitaxial, layer-by-layer growth of silver on the palladium substrate. High-resolution (in both energy and angle) photoelectron spectra and ab initio density-functional band-structure calculations are compared for 1 and 2 ML silver films along the Gamma-M-' high symmetry line of the surface Brillouin zone. The observed d-derived electronic states and their dispersion are explained in terms of quantum well states. The interaction of the silver 4d electronic states with the palladium substrate is discussed.
