Hybrid management of iliac injury during thoracic endovascular aortic repair: A case report. SAGE Open Med Case Rep 2024; 12:2050313X241236328. [PMID: 38784242 PMCID: PMC11113023 DOI: 10.1177/2050313x241236328] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 02/14/2024] [Indexed: 05/25/2024] Open
Abstract
Thoracic endovascular aortic repair is nowadays the preferred option to manage descending thoracic aorta diseases. However, despite feasibility and safety of the procedures, several complications may occur. We report the case of an 83-year-old female patient with inadvertent iliac rupture occurred during thoracic endovascular aortic repair. To limit massive bleeding, considering the patient's comorbidities contraindicating open surgical repair and the morphology of the arterial injury (circumferential rupture of the artery from its origin), we chose to perform a homolateral hypogastric and common iliac artery embolization and an aorto-uniliac balloon expandable stent graft deployment from the distal aorta to the contralateral common iliac artery. A femoro-femoral crossover bypass graft was performed to restore both lower limbs perfusion. Final angiography documented correct positioning and regular patency of the implanted grafts and bypass with no blood loss from the right iliac vessels. Despite careful preoperative assessment, iliac artery injury can represent a challenging complication of thoracic endovascular aortic repair, particularly in the setting of inadequate iliac diameter, calcification and vessel tortuosity, or when large-caliber introducers are required. The hybrid approach we describe is a valid and effective solution to minimize blood loss and avoid major consequences in the management of iatrogenic iliac artery rupture during endovascular procedures.

Abstract
We evaluated the use of autologus bone marrow stem cells transplantation in patients with critical limb ischaemia (CLI) not eligible for revascularization. Eighty consecutive patients candidate to amputation were enrolled in a single-centre retrospective study. The primary endpoint was defined as the amputation-free rate from stem cells transplantation. Secondary endpoints were the evaluation of transcutaneous oximetry and its predictive potential for probability of amputation and the evaluation of rest pain. Ankle brachial index, transcutaneous oxygen (TcpO2) and radiological imaging were performed at the enrolment and during the follow-up times. All patients were treated with auto transplant of bone marrow stem cells. Two patients died due to acute renal and acute respiratory failures. 19 patients were amputated from the thigh or leg. In total, 59 of 80 patients intended to thigh amputation saved the limb, preserving the plantar support. TcpO2 was found a predictive metric with an AUC equal to .763, and a threshold for a risk of amputation of 10% and 5% at the values ≤22.7 and ≤26.9 mmHg, respectively. Auto transplant of bone marrow stem cells seems to be a safe and an efficient option for CLI not eligible to revascularizzation.

Challenges and Pitfalls in CT-Angiography Evaluation of Carotid Bulb Stenosis: Is It Time for a Reappraisal? LIFE (BASEL, SWITZERLAND) 2022; 12:life12111678. [PMID: 36362834 PMCID: PMC9697210 DOI: 10.3390/life12111678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 10/13/2022] [Accepted: 10/20/2022] [Indexed: 01/25/2023]
Abstract
We aimed to perform an anatomical evaluation of the carotid bulb using CT-angiography, implement a new reliable index for carotid stenosis quantification and to assess the accuracy of relationship between NASCET and ECST methods in a large adult population. The cross-sectional areas of the healthy carotid at five levels were measured by two experienced radiologists. A regression analysis was performed in order to quantify the relationship between the areas of the carotid bulb at different carotid bulbar level. A new index (Regression indeX, RegX) for carotid stenosis quantification was proposed. Five different stenoses with different grade in three bulbar locations were simulated for all patients for a total of 1365 stenoses and were used for a direct comparison of the RegX, NASCET, and ECST methods. The results of this study demonstrated that the RegX index provided a consistent and accurate measure of carotid stenosis through the application of the ECST method, avoiding the limitations of NASCET method. Furthermore, our results strongly depart from the consolidated relationships between NASCET and ECST values used in clinical practice and reported in extensive medical literature. In particular, we highlighted that a major misdiagnosis in patient selection for CEA could be introduced because of the large underestimation of real stenosis degree provided by the NASCET method. A reappraisal of carotid stenosis patients' work-up is evoked by the effectiveness of state-of-the-art noninvasive contemporary carotid imaging.

Abstract
INTRODUCTION Carotid atherosclerotic disease is a known independent risk factor of post operative stroke after coronary artery bypass grafting (CABG). The best management of concomitant coronary artery disease and carotid artery disease remains debated. Current strategies include simultaneous carotid endoarterectomy (CEA) and CABG, staged CEA followed by CABG, staged CABG followed by CEA, staged transfemoral carotid artery stenting (TF-CAS) followed by CABG, simultaneous TF-CAS and CABG and transcarotid artery stenting. METHODS We report our experience based on a cohort of 222 patients undergoing combined CEA and CABG surgery who come to our observation from 2004 to 2020. All patients with >70% carotid stenosis and severe multivessel or common truncal coronary artery disease underwent combined CEA and CABG surgery at our instituion. 30% of patients had previously remote neurological symptoms or a cerebral CT-scan with ischemic lesions. Patients with carotid stenosis >70%, either asymptomatic or symptomatic, underwent CT-scan without contrast media to assess ischemic brain injury, and in some cases, if necessary, CT-angiography of the neck and intracranial vessels. RESULTS The overall perioperative mortality rate was 4.1% (9/222 patients). Two patients (.9%) had periprocedural ipsilateral transient ischemic attack (TIA) which completely resolved by the second postoperative day. Two patients (.9%) had an ipsilateral stroke, while 7 patients (3.2%) had a stroke of the controlateral brain hemisphere. Two patients (.9%) patients were affected by periprocedural coma caused by cerebral hypoperfusion due to perioperative heart failure. There were no statistically significant differences between patients in Extracorporeal Circulation (ECC) and Off-pump patients in the onset of perioperative stroke. CONCLUSION Our experience reported that combined surgical treatment of CEA and CABG, possibly Off-Pump, is a feasible treatment procedure, able to minimize the risk of post-operative stroke and cognitive deficits.

Chronic abdominal aortic rupture mimicking femoral neuropathy. SAGE Open Med Case Rep 2022; 10:2050313X221109973.

Abstract
Chronic-contained rupture of an aortic aneurysm is a rare subset of ruptured aneurysms. The presentation is unusual, and the diagnosis is frequently delayed. Here, we describe a case of contained rupture of abdominal aortic aneurysm that presented with signs and symptoms of femoral neuropathy. Clinical and radiological findings were initially misinterpreted. The correct diagnosis was formulated belatedly, causing a progressively increased risk of fatal events. Surgical aortic repair was performed and the postoperative course was uneventful. In conclusion, in the presence of a retroperitoneal mass, a diagnosis of chronic-contained rupture of an abdominal aortic aneurysm should be considered.

Intramural haematoma of the thoracic aorta: A case series. SAGE Open Med Case Rep 2021; 9:2050313X20983207.

Abstract
We reported four cases of intramural haematoma of the descending thoracic aorta. Four patients, aged 55-82 years, hypertensive, were transferred from the emergency room of other hospitals due to the appearance of epigastric pain and left thorax pain. All patients underwent computed tomography angiography reporting the presence of intramural haematoma. Three patients underwent a drug therapy to maintain a controlled hypotension. A computed tomography revaluation was performed documenting (1) an increase in the thickness of the intramural haematoma, (2) the appearance of a penetrating ulcer within the haematoma and (3) the appearance of several penetrating lesions throughout the thoracic aorta. Patients required the placement of one or two thoracic aorta endoprosthesis. For the fourth patient, the hyperdense appearance of the intramural haematoma and the presence of pleural effusion suggested an urgent treatment intervention. All patients underwent a placement of cerebrospinal fluid catheter and drainage before treatment. All patients were treated with endovascular intervention with 100% technical success and absence of migration or retrograde type A dissection. There were no complications related to femoral surgical access or access routes. Perioperative mortality was null; no patient had paraplegia. No strokes, transient ischemic attack or perioperative myocardial infarction were observed. The average hospitalization was 5 days. After 3 months, angio-computed tomography reported for all patients a complete reabsorption of the intramural haematoma and a complete exclusion of the penetrating ulcer of the aortic wall present at the time of the intervention. There have been no cases of distant thoracic aortic tears. Endovascular treatment must be considered the preeminent treatment for thoracic aortic haematoma. Best timing to perform the endovascular procedure depends on the patient clinical picture and on stability of hemodynamic parameters.

Incidental Finding of Dual Ectopic Thyroid on Computed Tomography Angiography. J Clin Imaging Sci 2017; 7:30.

Abstract
The presence of simultaneous two ectopic foci of thyroid tissue (dual ectopic thyroid) is rare, and few cases have been reported in the literature. The ectopic thyroid tissue is an extremely uncommon embryological aberration due to the alterations occurring during the embryological development with incomplete migration of thyroid precursors. Commonly ectopic thyroid tissue is a midline structures, but the lateral location is possible but very rare. Ectopic thyroid is common in women and can vary in size from a microscopic focus to a few centimeters. The normal process of migration of the thyroid can be interrupted at various levels determining a lingual ectopy, a sublingual ectopic, prelaryngeal ectopy, or mediastinic ectopy. Intrathoracic and subdiaphragmatic organs are other sites where the ectopic thyroid tissue may be present. In most of the cases, ectopic tissue is a lingual thyroid and this condition can be totally asymptomatic, discovered incidentally, or occurs with symptoms such as dysphonia, dysphagia, dyspnea, and hemoptysis. Sublingual or suprahyoid ectopia is rare and even rarer are the cases of two foci of ectopic thyroid tissue simultaneously present. On imaging, the ectopic tissue shows the same characteristics of orthotopic thyroid tissue and similarly can undergo goiterous and cancerous transformation. We report a case of incidental dual ectopic thyroid in lingual and suprahyoid level in a 72-year-old female patient, asymptomatic and with normal thyroid function, who underwent computed tomography (CT) angiography before vascular surgery for the treatment of carotid stenosis. The presence of a lingual thyroid can lead to a difficult and dangerous intubation, with possible fatal consequences. For this reason, the discovery of these abnormalities has totally changed the patient management who has been subjected to endovascular treatment, instead to the classical surgery.

Abstract
The purpose of this report is to present the case of a 59-year-old man affected by multivessel coronary artery disease and sterile pseudoaneurysm of the right carotid bifurcation presenting as a pulsating neck mass 1 month after patch-free carotid endarterectomy. The surgical approach included median sternotomy and incision parallel to the anterior margin of the right sternocleidomastoid muscle. The pseudoaneurysm was excised after control of the brachiocefalic trunk and insertion of a Pruit-Inahara shunt, and the carotid vessels were directly sutured without using any prosthetic or autologous material. Concomitant coronary bypass grafting was performed. The postoperative course was uneventful and there was no evidence of recurrence of pseudoaneurysm at 6-month follow-up. On the basis of this experience and of pertinent literature, the options for the management of such rare entities are discussed.

Abstract
PURPOSE To describe the successful management of a symptomatic persistent sciatic artery (PSA) aneurysm using the Multilayer Aneurysm Repair System (MARS). CASE REPORT A 50-year-old man with history of smoking, hypertension, and hypercholesterolemia suddenly developed pain in the buttock radiating to the left lower limb, mimicking sciatica. The ∼57×54-mm incomplete type PSA aneurysm was treated with two 14×80- and 14×60-mm MARS devices through a surgical left axillary artery access. There were no periprocedural complications. Thirty-day imaging documented patency of the stents and a minor reduction (∼47×55 mm) in the aneurysm, with slightly hyperdense content and no signs of perfusion. At 6 months, duplex and computed tomographic angiography showed complete thrombosis of the sac, patency of the multilayer stents, and further aneurysm shrinkage (40×37 mm). CONCLUSION The multilayer stent can alter the hemodynamics inside a peripheral aneurysm to promote sac thrombosis and redirect flow to collaterals originating from the sac.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Diabetes mellitus is an established risk factor for leg wound healing complications after great saphenous vein harvest. Leg healing complications occur in 1-25% of coronary artery bypass graft patients, and are often underestimated. PATIENTS AND METHODS The records of 230 patients enrolled in a prospective trial to evaluate a minimally invasive approach compared with conventional longitudinal harvest were reviewed. Of 100 patients with diabetes, 49 had undergone minimally invasive harvest (group A). Forty-nine patients from the pool without diabetes who underwent minimally invasive harvest were selected using propensity scoring analysis (group B), and 46 diabetic patients operated using a conventional technique (group C) were matched to group A patients. Ninety-five patients with and 49 without diabetes finally entered the study. The quality of leg wound healing was quantified by ASEPSIS score by two independent surgeons in a blinded manner. The occurrence of complications was compared between groups. RESULTS Fewer leg wound healing complications occurred in diabetic patients in the minimally invasive compared with the conventional group (P < 0.0001). Rates of complications were comparable among diabetic and non-diabetic patients operated using the minimally invasive technique. The intraoperative flow of vein grafts obtained by the minimally invasive technique was comparable to that of veins harvested using the conventional technique. CONCLUSION These data suggest that postoperative leg wound morbidity can be significantly attenuated by the adoption of a less invasive approach, even in high-risk patients with diabetes. The advantages are not offset by the co-existence of other cardiovascular risk factors or by a long history of diabetes.

Abstract
BACKGROUND The Ultracision Harmonic Scalpel is associated with several advantages in radial artery (RA) harvesting. It allows fewer hemostatic clips to close the collateral branches, less thermal injury of the conduit, and reduced time of harvesting in comparison with the conventional RA harvesting technique with electrocautery and hemostatic clips. We recently started open RA harvesting with the harmonic shears (HSH). In this study, we aimed at evaluating the feasibility of this simplified ultrasonically activated harvesting technique, and report the results of RA harvesting with HSH. METHODS The RA harvesting with HSH was performed in 20 patients operated on for myocardial revascularization from July 2004 to December 2005. RESULTS The harvest of the RA was completed in little time, without any complication. Neither bleeding from the collateral branches nor spasm alongside the entire length of the RA was observed. No bleeding occurred from the muscles of the forearm. CONCLUSION This technique of RA harvesting with HSH is impressive in terms of short time of harvest, complete absence of clips for the collateral branches, and no thermal injury of the conduit.

Abstract
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.

Abstract
INTRODUCTION AND BACKGROUND Myocardial revascularization using internal thoracic arteries (ITAs) has been associated with superior clinical outcome. This study addresses the question of whether internal mammary arteries are unsuitable for grafting due to radiation-based damage in patients with history of thoracic radiation therapy. We review our experience in this subset of surgical candidates. PATIENTS AND METHODS Forty-nine patients undergoing elective coronary artery bypass grafting with use of at least one ITA were enrolled and matched to 49 comparable nonirradiated individuals by propensity scoring system. Preoperative and postoperative data were collected and compared. A 18-month clinical follow-up was performed. RESULTS Intraoperative mammary artery flow was assessed by transthoracic Doppler echocardiography probe, and there was no significant difference between irradiated and nonirradiated individuals (36 +/- 8.3 mL/min vs 39 +/- 7.2 mL/min, p = 0.15). The two study groups were also comparable in terms of survival (overall mortality, 2%) and recurrence of angina and perfusion defect at control stress perfusion nuclear scan (p = 0.99 and p = 0.77, respectively). One arterial graft showed stenosis at postoperative angiography. The dose of radiation therapy administered did not correlate with graft flow values after anastomosis. CONCLUSION Our data suggest that the use of a monolateral or bilateral ITA is not associated with early graft failure in patients with history of chest/mediastinal irradiation. Skeletonization harvesting technique might be recommended because of the frequent presence of fibrous tissue around the in situ vessel. Arterial graft stenosis in thorax-irradiated patients should be attributed to the primary atherosclerotic disease rather than to irradiation itself.

Abstract
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.

Abstract
This study is a retrospective analysis of the impact of intravascular ultrasound in addiction to conventional angiography in 36 patients with 55 stenotic peripheral arterial lesions treated with angioplasty and/or stenting. Before treatment, intravascular ultrasound imaging showed that the vessel diameter was underestimated with angiography in 6 cases. The correlation index between angiography and intravascular ultrasound measurements, however, was significant in 27 arterial lesions. After endovascular treatment, angiography showed 3 vessel dissections and no incomplete stent deployment, whereas intravascular ultrasound showed 15 dissections and 5 instances of stent underdeployment. If we consider the intravascular ultrasound data as the gold standard, the specificity of angiography is 100%, while its sensitivity is 56% for vessel dissection and 75% for stent deployment. In the follow up of the 16 patients treated for iliac lesions with intravascular ultrasound control, re-stenosis occurred in 5% (primary patency 94.7%); in a control group of 15 patients treated in the same period without intravascular ultrasound control, re-stenosis occurred in 15.8% (primary patency 83.4%, difference not statistically significant). In conclusion, in the peripheral arteries intravascular ultrasound is more accurate than arteriography in evaluating dissection and stent deployment, but the routine use of intravascular ultrasound in every case of iliac PTA or stenting would not appear justified.

Abstract
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.

Abstract
This study reports on 10 years of experience in observing diverticular disease. The study considers 77 patients, 41 males and 36 females, aged from 50 to 88 years (mean age: 70 years), observed from January 1991 to December 2001. Sixty-two patients were admitted from the Accident and Emergency Unit and 15 were elected patients. Five patients underwent emergency surgery, while 72 received only antibiotic therapy. The overall mortality rate was 0. The morbidity rate was 22% in those patients undergoing emergency surgery. In only one of the elected patients was wound suppuration detected. Diverticular disease, in most cases, is treated by antibiotic therapy alone, but in 30% of cases surgery is necessary. Colon resection and immediate anastomosis are the first choice operation also in the emergency setting, provided local conditions (inflammation, septic contamination) make anastomosis safe. In patients with major peritoneal contamination, Hartman's operation and subsequent recanalization after 6 months are to be preferred.

Benign multicystic mesothelioma of the peritoneum: a case report. CHIRURGIA ITALIANA 2002; 54:569-72. [PMID: 12239771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 02/26/2023]
Abstract
The aim of this study is to report the experience of a case of benign multicystic mesothelioma of the peritoneum presented with acute appendicitis symptomatology. A 28 years old man with right lower and upper abdominal pain was admitted into hospital. Because of the clinical picture, the symptomatology and the leukocytosis a diagnosis of acute appendicitis was made and the patient underwent appendicectomy according to Mc Burney. At laparotomy some cc of purulent fluid were sucked and a cystic mass that contained clear fluid was revealed. In consequence of the incidental diagnosis a following middle laparotomy was made with a careful surgical excision of the mass and of the appendix. Macroscopically the lesion was identified like a neoplastic mass 25 centimeters in diameter, with a multicystic and fibrous-adipose aspect, with cysts 5 centimeters in diameter. The cystic spaces were lined by a layer of eptelial cells which presented positive reaction for cytokeratin and EMA, whereas endothelium markers were absent. The ultrastructural, morphological and immunohistochemical findings were diagnostic of a benign multicystic mesothelioma.

Follicular adenoma of the thyroid gland with extensive bone metaplasia. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2001; 20:443-5.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.
