Traumatic rupture of the thoracic aorta.

Traumatic rupture of the thoracic aorta is a life threatening situation, and may be secondary to several mechanisms; mainly penetrating or iatrogenic lesions and blunt trauma. Although penetrating mechanisms predominate, the number of patients with aortic disruption due to blunt trauma has continued to increase. This paper shows an overview focusing on the pathogenesis, diagnosis, timing and type of treatment regarding traumatic injuries of the thoracic aorta; it also reports the experience of one single center that deals with these lesions. The major difficulty in the evaluation data on blunt aortic injury is that retrospective reviews often group together patients with all types of aortic lesions, comparing outcomes for injuries in different locations, with diverse methods of repair and different surgeons and/or institutions.

Follicular adenoma of the thyroid gland with extensive bone metaplasia.

Follicular adenomas of the thyroid account for over 90% of benign neoplasms of the gland. They exhibit a wide range of morphological structures, from the classical follicular pattern to the peculiar hyalinizing trabecular pattern. Although follicular adenomas grow slowly, they are nonetheless subject to degenerative, most often hemorrhagic changes in their central portion. These hemorrhagic areas undergo further regressive changes such as sclerosis and calcification. However, the detection of a true bone formation with a trabecular structure and the presence of marrow is a very rare occurrence. A follicular adenoma with central cartilaginous metaplasia has been reported in literature but, to our knowledge, a follicular adenoma with bone metaplasia has never been described.

[Vascular cysts of the adrenals. Association with aneurysm of the abdominal aorta].

A rare case of an adrenal vascular cyst associated to an abdominal aorta aneurysm is reported. Adrenal cysts are an uncommon clinical finding, in most cases incidentally discovered for nonspecific abdominal pain, during US, TC or RM evaluation or at autopsy. Small adrenal mass are clinically silent. They may be symptomatic (lumbar tension, pain) for dimensions over 10 centimetres. Cysts of large size can cause displacement and compression of adjacent organs. They present a difficult problem of differentiation between benign and malignant lesions. Non-neoplastic adrenal cysts have been divided into four categories: parasitic (7%), epithelial (9%), endothelial (45%) and haemorrhagic or pseudocystic (39%). Vascular adrenal cysts may be a traumatic consequence of an hamartomatous vascular anomaly. The aim of this paper is to discuss, on the basis of the literature, the etiology, diagnosis and treatment of the adrenal mass. Surgical timing is discussed for the concomitant vascular lesion. The elective treatment was left adrenalectomy performed through transperitoneal approach. Surgery for abdominal aorta aneurysm was differed because the adrenal mass was suspected to be an infected neoplastic lesion and for the feasibility of endovascular procedure. The adrenal specimens contained a cystic structure with fluid blood, fibrin and calcifications. Normal adrenal cortical tissue was found in the cystic wall. This lesion (arising from vascular anomalies) require separation from haemorrhagic adrenal neoplasm. Awareness of adrenal pseudocysts and careful attention to the hystological features aids this distinction.

[Drainage in thyroid surgery].

Bleeding represents a rare complication of thyroid surgery but when it occurs it may be life-threatening. To prevent this complication drainage is widely used. However no study has demonstrated the drains' value and recent reports have questioned its benefits. Therefore we have analyzed our experience of a 10 year-period in which 1.217 thyroidectomies were performed by the same surgical team and prophylactic routine drainage was always adopted. In 13 patients (1.06%) a benign hematoma occurred with spontaneous remission. In 6 patients the bleeding was severe and compressive hematoma occurred; it required surgical re-exploration. Such a complication is unusual in the neck surgery (0.49% in the authors' series) performed by experienced surgeons and when life-threatening hematomas do occur they depend on various uncontrolled factors and drainage is often not helpful. Otherwise a meticulous haemostatic technique is necessary and patients should be observed very closely during the few first hours following surgery on the thyroid gland. Therefore on the basis of the analysis of their series, although it is not always possible to prove the benefit of the drainage, the authors suggest its indication in the neck surgery, as in other fields with dead space, to remove blood and secretions reducing postoperative complications. They have never observed wound infections and patients were discharged within 72 hours.

[Papillary microcarcinoma [correction of carcinoma] of the thyroid: clinical experience and prognosis factors].

Thyroid neoplasm of less than 10 mm in the largest diameter are defined as minimal thyroid cancer (MTC). These tumors are a common incidental finding at autopsy and in thyroid glands excised for other pathology. These tumors can metastasize and can cause significant morbidity and mortality. Clinical significance and optimal operative procedures of these lesions are still questioned. We studied 35 MTC in order to identify clinical and histologic characteristics as prognostic factors and to establish therapeutic management strategies. From January 1988 to December 1998, 177 patients with a primary thyroid cancer underwent surgery in the Department of endocrine-surgery of Catholic University in Rome: 35 of them (19.7%) had a MTC. In the post-operative follow-up 13 of the patients with MTC had a lymph node recurrency and/or distant metastases. Careful histologic examination showed multifocality in 12 patients, capsular infiltration in 10 patients and a solid tumor in 9 patients. MTC are common and they are associated with a good prognosis. Our multifactorial analysis has identified as important risk factors: capsular infiltration, solid lesion and multifocal disease. In these cases total thyroidectomy is mandatory.
