[Aneurysm of the hepatic artery. Case report and review of the literature]. / L'aneurisma dell'arteria epatica. Case report e revisione della letteratura.

Hepatic artery aneurysms (HAAs) are considered rare even though their reports in the literature are becoming more and more frequent. The great improvement in the diagnosis of vascular diseases and the increasing incidence of atherosclerosis have resulted in a wider recognition of these pathologies. Differently from other splanchnic locations HAAs have a high risk of rupture (up to 80%) so that an aggressive treatment is required. Different therapeutic options are currently available: simple ligation of the artery, aneurysm excision and vascular reconstruction, transcatheter embolization. However, the therapeutic choice must be evaluated in each single case, depending on the size, aspect and locations of the aneurysm, and requiring an accurate study of the collateral vascular supply. Finally, since additional aneurysms in other sites are frequent, a dose follow up of these patients is recommended.

[Cystadenocarcinoma of the pancreas. Case report and review of the literature]. / II cistoadenocarcinoma del pancreas. Caso clinico e revisione della Letteratura.

Pancreatic cystadenocarcinoma is a quite rare neoplasm. Due to the low incidence and recent nosographic arrangement, the natural evolution and the clinical development of this type of neoplasm are not well known. The Authors report their experience and a review of the Literature trying to establish the criteria for the classification, diagnosis and therapy of pancreatic cystadenocarcinoma.

[Mesenteric fibromatosis in Gardner's syndrome]. / La fibromatosi mesenterica nella sindrome di Gardner.

The paper reports a case of mesenteric fibromatosis with familial polyposis, an association which was diagnosed as Gardner's syndrome, and highlights the complications connected to mesenterial desmoid tumours. In addition, the importance of radical surgical therapy of these neoplasias is underlined. Lastly, it is hypothesised that full screening of patients affected by familial polyposis might show a greater incidence of association between widespread polyposis and pathological changes attributable to Gardner's syndrome.

[Popliteal artery entrapment]. / L'intrappolamento dell'arteria poplitea.

The Authors present a case of popliteal artery entrapment syndrome due to an anomalous insertion of medial head of the gastrocnemius muscle. The patient, a 47-year-old man, with calf claudication, was examined with Doppler velocimetry and angiography. He was successfully treated by surgical intervention. A medial approach to the popliteal artery was utilized and the section of anomalous head of gastrocnemius muscle and popliteal thromboendarterectomy were performed. The postoperative course was uncomplicated.
