[Multiple hamartomas of the bile ducts (MBDH) or von Meyenburg's complex]. / Amartomi multipli dei dotti biliari (MDH) o complesso di Von Meyemburg.

Multiple bile duct hamartomatosis of the liver or so-called von Meyenburg's syndrome, is an infrequent disease related to a dysembryogenic error. The authors discuss clinical features, diagnostic methods and possible related pathologies. Data reported in the literature are also received.

[Aneurysms of the visceral arteries: the diagnostic problems and therapeutic strategies]. / Gli aneurismi delle arterie viscerali: problematiche diagnostiche e strategie terapeutiche.

Intestinal artery aneurysms are a rare clinical condition, usually asymptomatic. However, sometimes they occur as vascular emergency, with a mortality rate of about 75%. Therefore, their occasional diagnosis should be carefully considered as an indication for elective surgery. The authors report their experience in the surgical management of 3 cases of intestinal artery aneurysms respectively involving the splenic, the gastroduodenal and the inferior mesenteric artery. A review of the literature is also presented.

[Endometriosis of the distal ileal loop. A clinical case report]. / Endometriosi dell'ultima ansa ileale. Descrizione di un caso clinico.

Intestinal endometriosis is a rare lesion characterized by a difficult differential diagnosis with other intestinal diseases. The authors report the case of a woman suffering from endometriosis involving the distal ileal loop.

[A rare thyroid vascular anomaly: a unique thyroid artery arising from the right carotid bifurcation]. / Rara anomalia vascolare tiroidea: unica arteria tiroidea a partenza dalla biforcazione carotidea destra.

The evidence of thyroid vascular anomalies is is frequent and may manifest itself with an anatomic alteration. The absence of the inferior thyroid artery is reported in 1% of the cases, while a thyroid artery arising from the common carotid artery has been found in 2% of examined patients. In the observed case we retain that the rarity is not only due to the contemporary presence of two anomalies, but also to the presence of an anomalous vessel which arises from right carotideal bifurcation and bloody supplies either right lobular or left lobular of thyroid, thus resulting the sole gland's arterial vessel.

[Prosthetic salvage operation in patients on hemodialysis]. / L'intervento di "salvataggio protesico" nei pazienti in emodialisi.

The use of PTFE, vascular prosthesis (Gore-Tex), in the vascular access for hemodialysis, is a very reliable and exploited method. Thrombosis is the most frequent complication. The prosthetic "salvage operation" allows an immediate functional recovery. The authors examine their series from 1986 on, analyzing the surgical technics employed and the results obtained.
