The Authors report a case of mycotic aneurysm of the celiac trunk, originating from bacterial endocarditis on the mitral valve. The technique was excision and revascularization without interposition of any material: for the moment it is the first time that a mycotic aneurysm of the celiac trunk is treated in this manner. The post-operative course was normal.

The Authors report a case of coeliac axis atheromatous obstruction, with superior mesenteric artery steal. The coeliac axis, stopped up the origin was indirectly revascularized by hepatic artery. The early diagnosis of chronic intestinal ischaemia should avoid the intestinal infarction. The development of intravenous digital angiography will certainly help an early diagnosis.
A case of emergency revascularisation of the hepatic artery for liver necrosis following its forced ligature during corpo-caudal pancreatectomy for cancer of the pancreas in referred. Necrosis protection mechanisms, namely higher portal flow, increase in O2 extraction and collateral circulation are analysed. The therapeutic aids for preventing this serious event are presented. It is considered that peripheral expansion of the hepatic artery thrombosis prevented the installation of a valid collateral circulation, although the hypothesis of a reduction in portal flow should not be ignored.
After a wide analysis of the problems concerning biology and integration of autogenic transplantation of tooth germs, the Authors present a clinical case of monolateral agenesis of two premolars, with the transfer of the second premolar germ from one side to an other, suggesting some technical details in flap scalloping.

The authors illustrate the orthodontic-prosthetic resolution in a child. The necessity to re-establish a physiological occlusal balance, without altering growth and without damaging teeth tissues, is analyzed.

A case of an aneurysm of the left ventricle associated with recurrent hemorrhagic pericardial effusion is described. A small conduit connecting the left ventricle to the pericardial cavity was identified by left ventriculography. The mechanisms which prevented sudden cardiac tamponade and death are discussed.
