RESUMO
Diabetic foot (DF) is a chronic and highly disabling complication of diabetes. The prevalence of peripheral arterial disease (PAD) is high in diabetic patients and, associated or not with peripheral neuropathy (PN), can be found in 50% of cases of DF. It is worth pointing out that the number of major amputations in diabetic patients is still very high. Many PAD diabetic patients are not revascularised due to lack of technical expertise or, even worse, negative beliefs because of poor experience. This despite the progress obtained in the techniques of distal revascularisation that nowadays allow to reopen distal arteries of the leg and foot. Italy has one of the lowest prevalence rates of major amputations in Europe, and has a long tradition in the field of limb salvage by means of an aggressive approach in debridement, antibiotic therapy and distal revascularisation. Therefore, we believe it is appropriate to produce a consensus document concerning the treatment of PAD and limb salvage in diabetic patients, based on the Italian experience in this field, to share with the scientific community.

A 49-year-old operated for aortic coartaction patient presented with thoracic and ascending aortic aneurysm. He was asymptomatic. Angio-magnetic resonance nuclear scan and angiography revealed an ascending aortic aneurysm (5.2 cm), bicuspid aortic valve, 6-cm proximal descending aortic pseudoaneurysm at the site of the previous operation with involvement of the left subclavian artery. Restenosis at the original site of coarctation and aortic arch hypoplasia distally to the brachiocefalic trunk was also found. The operation performed was a "modified Bentall - De Bono". The pseudoaneurysm was not accessible through median sternotomy due to the massive lung adhesions following the previous surgery. The left common carotid artery was explanted from the aortic arch and connected with a graft to the ascending aortic conduit. A proximal neck suitable for landing zone of the endovascular stent-graft was then established. The postoperative course was uneventful. After two weeks, the patient was readmitted. The exclusion of the thoracic descending aortic pseudoaneurysm by endovascular implantation of the stent-graft prosthesis was performed. The left subclavian artery was excluded because left vertebral artery was closed. The patient did not develop hand claudicatio. The procedure was successful.

AIM: To compare the postoperative courses of patients subjected to closure procedure or stripping of the great saphenous vein (GSV). METHODS: We examined 2 groups of 15 patients with ostial and truncular saphenous insufficiency matched for CEAP clinical and anatomic classes. Group A patients underwent saphenous closure; short stripping was performed on those of Group B. In the Group A surgery was performed under spinal (12) or local (3) anesthesia; the procedure was preceded by crossotomy (5), crossectomy (1) or saphenous ligation (8); in 11 cases micro-phlebotomies were associated. In the Group B surgery was performed under general (5), spinal (7) or local (3) anesthesia; the procedure always was preceded by crossectomy (1); in 11 cases micro-phlebotomies were associated. RESULTS: Group A patients were discharged 6-18 hours after surgery. None presented ecchymosis, hyperemia or skin lesions. Five complained of mild aching thigh pain, which did not require pain medication. All resumed normal daily activities the day after surgery and returned to work after 4.9 days. Six months after surgery, none of the patients had evidence of saphenous vein re-channeling. Group B patients were discharged 12-18 hours after surgery. Nine had ecchymosis on the thigh. Five reported mild thigh pain requiring analgesics. Normal daily activities and work were resumed 2.7 and 9.3 days after surgery. CONCLUSIONS: This retrospective study seems to confirm that endoluminal radiofrequency ablation of the GSV provides good immediate results with no significant complications and can reduce postoperative pain and the length of convalescence with respect to those of stripping.

Solid-tumor metastases of the spleen are rare and usually associated with disseminated disease. There are only seven reports in literature of isolated splenic metastases from colorectal carcinoma, which generally metastasize to regional lymphonodes, liver and abdominal peritoneum. We report a case of isolated splenic metastasis in a 55-year-old woman who had undergone left hemicolectomy, lymphadenectomy and chemotherapy 18 months earlier for adenocarcinoma of the sigmoid colon with positive pericolic and inter-aortocaval lymphonodes. This is the eighth documented case of isolated splenic metastasis from colon cancer. Previously reported cases of this type are reviewed along with the mechanism underlying neoplastic spread to the spleen.

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.

The efficacy of cryotherapy, following the use of an ice bag, is evaluated in 21 patients of both sexes suffering from epicondilitis of the humerus. This treatment improved the clinical syndrome (pain and functional limitation) in 67% of the patients. Good results (4 cases - 19%) and negative results (3 cases - 14%) were also found, with the possibility of a relapse in the latter group.

During the performance of 1018 thyroid operations, 1497 recurrent laryngeal nerves were identified and exposed. Of the 773 visualized nerves on the right side, 2 were found to be non recurrent (0.26%). This abnormality may represent a pitfall during thyroidectomy even for very experienced thyroid surgeons. We emphasize that the exposure and preservation of this vital structure is the standard of care and an essential component of routine dissection in thyroid surgery.

Surgery of differentiated thyroid carcinoma is burdened with risk factors that significantly impact on prognosis, as age at diagnosis and tumor stage. Problems involved concern the extent of surgical resection and the indication for regional lymphadenectomy. As for the former, the most popular approach is total thyroidectomy "on principle" with neck lymphadenectomy. Lobectomy may represent an alternative to total thyroidectomy in low risk patients with unifocal papillary carcinoma 1 cm or less in size, or minimally invasive follicular carcinoma. As for lymphadenectomy, most authors do not agree with surgery "on principle" but rather "of necessity", that is, in presence of clinically evident lymphadenopathy and neck lymphadenectomy is the preferred surgical strategy. In most cases surgery is the treatment of choice of locoregional recurrence. Careful preoperative work-up and accurate surgical procedure are mandatory.

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.

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.

Preventive treatment with tiadenol administered to rabbits given experimental multiple fractures succeeded to a certain extent in modifying the adipose pulmonary embolism process. Since the drug is able to reduce tissue lipolysis, it was deduced that this enzyme is of limited importance in the genesis of adipose embolisms.

It has been confirmed that epsilon-aminocaproic acid (EACA), an inhibitor of fibrinolysis, reduced the incidence of fat embolism in the lung of rabbits with experimental bone fractures. Microscopic specimens of lungs, examined under polarized light, demonstrated the reduced amounts of lipoid materials that were prevalently undergraded. The action of the drug is owed to the inhibition of some primary mechanisms, involved in the genesis and diffusion of post-traumatic fat embolism.

Present study demonstrated that aprotinin, a natural inhibitor of proteases, interfered with the ossification process of epiphyseal and metaphyseal cartilages of growing rabbits. This biological effect may be induced by inhibition of tissue proteases, that acts on cartilage matrix to produce a substance which is an important component of the calcifying mechanism during enchondral ossification.

The association of a functional parathyroid cyst with a parathyroid adenoma is an uncommon finding. In this report we describe the clinical history of a 60-yr-old man, presenting with the following findings: hypercalcemia (18.9 mg/dl), elevated serum parathormone levels (1320 pg/dl), hypercalciuria (228 mg/dl), and hyperphosphaturia (155 mg/dl). Neck ultrasound, magnetic resonance imaging (MRI) and 99Tc Sestamibi scintigraphy led to the identification of a left parathyroid adenoma, located at the lower pole of the left thyroid gland lobe, associated with a parathyroid cyst, located at the upper extremity of the same thyroid lobe. Parathyroidectomy was performed and the histological examination confirmed the diagnosis of a parathyroid adenoma with aspects of cystic degeneration and an upper parathyroid cyst. Analysis of the crystal clear intracystic fluid showed elevated parathyroid hormone (PTH) levels (137.000 pg/ml). The patient is normocalcemic at 2 yr after surgery without signs of recurrent parathyroid enlargements. Aetiology, diagnosis and management of parathyroid cyst will be discussed.

OBJECTIVES: The aim of the present study was to apply a rational plan for simultaneous cardiac and carotid surgery in high-risk patients. MATERIALS AND METHODS: A consecutive series of 89 patients with coexisting severe cardiac and carotid disease were operated on during a 5-year period with routinary carotid shunting, moderate hypothermia and balanced anaesthesia. The combined surgical procedures were coronary artery by-pass grafts (CABG) + carotid endarterectomy (CEA) in 81 patients, CABG + CEA + aortic valve replacement (AVR) in four patients, and four cases of CEA + AVR. RESSULTS: Two deaths (2%), three acute myocardial infarctions (3%) and one (1%) major stroke occurred in five patients during the perioperative (30 days) period for a combined rate of death and/or disabling stroke of 3%. There were five reversible neurological deficits. Carotid and aortic mean clamping times were 9 and 60 min respectively. Patients were discharged after a mean length of stay in Intensive Care Unit (ICU) of 131 h and 7 days of hospitalisation post-ICU. CONCLUSIONS: Based on our results, combined interventions of CEA and CABG can be performed with an acceptable morbidity and mortality when severe carotid stenosis is associated with advanced, symptomatic cardiac disease. The management of these patients needs careful and appropriate pre-intra and post-operative assessment and timing aimed to reduce the ischaemic injuries, both cardiac and cerebral, especially during CBP time.
