[Surgical techniques in ruptured abdominal aortic aneurysm].

In recent years we are observing an increasing number of authors. The surgical results, in the elective cases, are improved drammatically, and now, in many Centers, the mortality rate is less than 5%. We haven't observed the same improvements for the emergency cases.

[Appendiceal "mucocele": apropos of 2 cases].

Two patients affected by appendiceal mucocele underwent emergency operation in our Department. Clinical findings and surgical management of the disease are discussed as well as controversy regarding the pathologic classification of the disease. The term "mucocele" is not referred to an exact histopathologic lesion: it describes the gross enlargement of the appendix, due to the accumulation of mucus in the dilated lumen.

[Aneurysms of the popliteal artery. Our clinical and therapeutic contribution].

The authors report their experience in 10 cases of popliteal artery aneurysms. By the data of the literature the popliteal artery is the second place most affected by aneurysmatic injuries, immediately after the abdominal aorta. The authors think that the optimal treatment is the by-pass with the autologous vein graft versus all other types of prostheses.

[Squamous-cell carcinoma of the thyroglossal duct. A clinical case].

The authors report a rare case of squamous cell carcinoma arising in a thyroglossal duct cyst. The lesion is a malignancy arising directly from the lining epithelium of the thyroglossal duct remnant and as a rule has a poor prognosis with survival ranging from few months to few years.
