Abstract

The aim of this study was to demonstrate the usefulness of endovascular treatment for gastroduodenal artery pseudoaneurysm with an arteriovenous fistula after simultaneous pancreas-kidney transplantation. We describe the case of a 38-year-old man who underwent successful simultaneous pancreas-kidney transplantation. An asymptomatic pseudoaneurysm of the donor gastroduodenal artery with an arteriovenous fistula was incidentally diagnosed by routine color flow Doppler ultrasound (CDU) examination and confirmed by 3-D gadolinium-enhanced magnetic resonance angiography (MRA) 15 days after transplantation. Selective arteriography (via the right femoral artery) confirmed an arteriovenous fistula and a pseudoaneurysm of the donor gastroduodenal artery. The patient underwent successful endovascular embolization. At 11 months of follow-up, normal pancreatic function was reported. Endovascular treatment for gastroduodenal artery pseudoaneurysm with an arteriovenous fistula after pancreas transplantation obviates the need for surgical intervention

29. [Management of 'complicated' work fitness judgements among health care workers]

Author

Subjects
Adult, Male, Occupational Medicine, Health care workers, Fit to work, Heart Diseases, Brain Neoplasms, Health Personnel, Oligodendroglioma, Health Care Sector, Middle Aged, Risks for the patients, Hepatitis C, Disability Evaluation, Settore MED/44 - Medicina del Lavoro, Humans, Female
Abstract

The occupational physician, performing health surveillance within a hospital, may face to some difficulties due to the variety and complexity of the tasks and the health risk factors of the health care workers. One of the hardest issue for occupational physician is to provide judgement on worker's fitness. Moreover, this task could be more complicated when a impaired worker could represent an hazard for his patients and colleagues. The authors will illustrate three critical clinical cases examined in Occupational Health Unit of Luigi Sacco Hospital, Milan; furthermore, the authors will show the difficulties and the applied solutions in order to provide the judgement on worker's fitness.

Abstract

We studied the main ocular and retrobulbar vessels with color-Doppler US and report on examination technique, detectability of the vessels and their flow characteristics to define the normal ranges of Doppler spectra for each artery and vein. We comparatively examined both eyes of 20 healthy subjects. Of each eye we studied the ophthalmic artery, the central retinal artery, the ciliary artery, the central retinal vein and the superior ophthalmic vein. The following flow parameters were considered: peak systolic velocity, end-diastolic velocity and resistive index for arteries; maximum and minimum velocity for veins. The examination lasted about 10 minutes per eye--20 minutes for each subject. In all subjects the five investigated vessels were identified in both eyes, and adequate Doppler spectra were obtained. The average peak systolic velocities of ophthalmic, central retinal and ciliary arteries were respectively about 35, 12 and 10 cm/s, with low resistance patterns (resistive index: 0.75, 0.72 and 0.68, respectively). The venous flow, which is usually continuous, may be sometimes influenced by cardiac and respiratory activities: the maximum velocities of superior ophthalmic and central retinal veins were about 6 and 5 cm/s, respectively. Color-Doppler US noninvasively visualizes both ocular and retrobulbar vessels, providing major hemodynamic information from different flow parameters; the knowledge of these parameters in normal conditions can be the basis of hemodynamic studies in many abnormal orbital conditions.

Abstract

This work was aimed at assessing Magnetic Resonance (MR) accuracy in the preoperative investigation of abdominal aortic aneurysms, with a view to suggesting MRI as the method of choice for surgical planning, replacing other relatively invasive investigation techniques like angiography and enhanced CT. In the last 3 years 80 patients with abdominal aortic aneurysms identified with US or CT were examined with 0.5-T MRI and underwent surgical repair within 15 days. Spin-echo (SE) T1-weighted axial, sagittal and coronal sequences were always performed. In 18 patients gradient-echo (GE) flow sequences were also acquired; SE T2-weighted sequences were used to study parietal thrombi in 10 patients and finally Gd-DTPA T1-weighted sequences were obtained in inflammatory aneurysms (3 patients). MR images were blindly evaluated by 2 radiologists. The following variables which are useful for surgical planning were considered for each patient: aneurysm extent, characteristics of parietal thrombi, dissections, fixurations, inflammation signs, involvement of renal arteries, vena cava, ureters, duodenum, the presence of retroaortic renal vein or of other anomalies or associated conditions. MR images were always compared with intraoperative findings, since surgery was considered as the gold standard. MR findings were in agreement with surgical findings in the evaluation of cranio-caudal aneurysm extent (78/80), parietal thrombus features (80/80), dissection (1/1) and fixuration signs (8/9), origin of renal arteries (80/80), inferior vena cava involvement (3/3), other anatomical anomalies or conditions (6/6). Inflammation signs were overestimated (14/8) as well as adhesion between aneurysm and duodenum (17/13). The presence of distal renal polar arteries was underestimated (2/4). In conclusion, MRI proves to be a highly sensitive method to demonstrate abdominal aortic aneurysms and is therefore suggested as the examination of choice before surgery.
