Epithelioid hemangioendotheliomais a low to intermediate grade malignant vascular tumors that can involve any organ. About 60-80%of patients are women, patient ages range 7 to 81 years, with a median age of 38 years. Four cases of thoracic epithelioid hemangioendotheliomas with different clinical presentation and disease progression are reported. Cases 1 and 2 are pulmonary epithelioid hemangioendotheliomas diagnosed at different advanced stages and patients died after 6 and 2,5 months of medical treatment, respectively. Case 3 corresponds to pleural epithelioid hemangioendothelioma, submit- ted to left lung decortication and pleuro-pericardial window; patient is free either from symptoms and radiographic manifestations for 10 months of follow-up. Case 4, of mediastinal epithelioid hemangioendothelioma, represented by a mass in the upper left mediastinum adherent to the aortic arch; patient underwent block excision of the mass followed by chemotherapy; subsequent recurrence 41 months later and the patient died 8 months after. The reported 4 cases reveal the heterogeneous clinical presentation of epithelioid hemangioendotheliomas with behavior in between benign and high-grade tumors, raising difficulty in either differentiating from other vascular tumors and previewing clinical outcome.

Introduction: Intravascular foreign body (IFB) embolization is a potential complication of any vascular procedure. Intravascular foreign body retrieval (IFBR) can be achieved using percutaneous techniques, open surgery, or both combined. Methods: We completed a retrospective review of patients who underwent endovascular or open IFBR since 2011 on our institution. Primary end-point was technical retrieval success, and secondary end-points were procedure-related compli- cations and 30-days survival. Results: Twenty-seven patients underwent IFBR. Median time from intravascular device loss and retrieval was less than one day. 67% were non-endovascular guidewires and sheath fragments (N=28). 59% of IFBs were lost during their deployment (N=16); 41% during their removal attempts (N=11). 44% were lost in the arterial system (N=12) and 52% in the venous system (N=14). An endovascular procedure was used as the first approach in IFBR in 56% of patients (N=15) and open procedure in 44% (N=12). In the presence of IFB on the thoracic or abdominal cavity, it was always tried a first-endo approach; if IFB was present on the neck or limbs, 75% were retrieved by open surgery (N=20; p<0.001). Success rates were 100% for open and 87% for endovascular procedures. IFB caused five acute complications: one IJV thrombosis, two strokes and three acute limb ischemia. There were no IFBR-related complications. 30 days-survival was 100%. Conclusion: Embolization of IFBs can be minimized with proper device selection, deployment and removal. In this study, open and endovascular retrieval had high success rates and minimal morbidity. Its choice is surgeon-dependent and restrained by devices availability.

We present a rare case of a considerable chest wall mass surgically resected in a patient. A 59-year-old woman was submitted to complete excision of a chondrosarcoma from her 4th right rib 15 years before. After that time, the patient presented with a mass on her right hemithorax, which revealed to be a recurrence after the biopsy. Chest Computed Thomography (CT) and Magnetic Ressonance Imaging (MRI) scans indicated 21x19.5x24 cm of dimen- sion, from supraclavicular fossa to upper abdomen, with the destruction of the 4th, 5th and 6th right ribs, insinuating over the right lung, axillary vases, right hemidiaphragm and hepatic parenchyma.The patient was submitted to a complete enbloc excision of the mass, four ribs, atypical resection of the right lower lobe, partial resection of the right hemidiaphragm and reconstruction of the thoracic wall with polypropylene and methacry- late proteses covered with local soft tissue. The anatomical specimen weighted approximately 11kgs. After four days in intensive care and five days in the infirmary, the patient was discharged home; one month later she was readmitted to treat a seroma of the right hemithorax. To date the patient is well, with no sign of recurrence.

Introduction: Pulmonary embolism (PE) is a potentially fatal disorder that occurs as a result of a thrombus formed in the deep venous system that detaches and obstructs the pulmonary artery or one of its branches. Herein we report a rare, bilateral PE after surgical correction of the Achilles tendon. Objectives: To report a bilateral PE after calcaneus tendon repair, and to review the literature on this rare condition. Materials and Methods: A search of the literature was carried out in electronic databases and a review of medical records. Conclusion: PTE, although rare, is a serious and potentially fatal complication, requiring adequate and early treatment. Pharmacological prophylaxis in these situations is still controversial in the medical literature; however, there is consensus for the use of intermittent pneumatic compression in the postoperative period.

Mediastinal teratomas presenting in the pediatric age are extremely rare. We report three cases of mediastinal teratomas in children aged 15 months to 9 years. Patients were submitted to complete tumor resection, with an uneventful postoperative course and follow-up. Our report emphasizes the importance of a detailed patient examination and careful interpretation of routinely performed image studies.

Objectives: Surgery provides the best chance for cure in patients with non-small-cell lung cancer stage I or II, but only a small portion of all new cases diagnosed are eventually suitable for surgical resection. Our goal was to appraise the surgical outcomes including survival and progression rates in patientswith histological diagnosis of lung cancer. Methods: Between 1st August 2012 and 30th June 2018, the patients with histological lung cancer diagnosis that underwent surgical resection with a curative intent at the department of Cardiothoracic Surgery of Centro Hospitalar Univer- sitário de São João were included. Results: The majority of patients were pathological stage I and the most performed surgery was a lobectomy (90.6%). The hospitality mortality was 1,3% and the rate of complication was 26,1%. Patients with forced expiratory volume in 1 second (FEV1) less than 80% had higher (statistically significant difference) frequency of complications. Active smokers, Eastern Co- operative Oncology Group Performance Status (ECOG PS)value different than 0 and FEV1 inferior to 80% had a higher mean length of drainage and higher mean length of stay (statistically significant difference). The overall survival was 92,6% at 1 year, 87,7 % in 2 years and 79,1% in 5 years. The overall survival according to pathological stages were similar when compared with the literature. Conclusions: Ours results are similar to international centers and we should be more alert to preoperative assessment.

84-year-old male, with a history of firearm incident with accidental gunshot shooting, and multiple projectile injuries, 40 years prior. No advanced medical treatment was required at the time. A CT was recently performed for unrelated reasons, and the scout view shows multiple projectiles, a total of 50, scattered in the thoracoabdominopelvic region as well as the lower limbs. CT angiography exposed CT’s scout view of the multiple projectiles scattered. an arteriovenous fistula in posterior branches of the hypogastric artery with moderate dilations of the superior gluteal vein. The patient was completely asymptomatic and had no findings suggestive of AVF-related cardiac failure. Physical examination was unremarkable. Conservative treatment without further imagiological follow-up was decided, if patient continued asymptomatic.

Background: The objectives of our study are to evaluate our surgical experience of mediastinal bronchogenic cyst (MBC) and to determine the results of resection by video-assisted thoracic surgery (VATS) and posterolateral thoracotomy (PLT). Methods: The demographic characteristics, clinical and radiological features intraoperative data, outcomes and fol- low-up information were reviewed and analyzed from 38 patients who underwent resection of a MBC between 2008 and 2019. Results: cystectomy was performed for thirty eight patients included in the present study. Seventeen of them, benefited from VATS cystectomy (VATS group) with 1 conversion to thoracotomy (5.9%) and 21 underwent PLT cystectomy (PLT group). In our series 27 (71.1%) were male. Their average age was 42.6 years. While 09 patients (23.7%) had no symptoms pre-operatively, 29 patients (76.3%) were symptomatic. There were no operative deaths and 3 patients (7.9%) presented postoperative complications. The average duration of hospital stay was 3.2 days for patients who had VATS, but 5.8 days for those who had thoracotomy. Long-term follow-up (range, 1 to 8 years) showed no late complications and no recurrence. Conclusion: VATS and PLT are main approaches for the surgical resection of MBCs VATS is a safe procedure, with less pain and time spent at the hospital. Early surgical procedures of MBCs may be recommended to prevent complications. Surgical adhesions are unfavorable conditions to thoracoscopic treatment.

A 57 year-old catheter dependent dialysed woman with systemic erithematous lupus and central vein stenosis underwent HeRO graft placement in right internal jugular vein. In the next months she had multiple arm infections and venous outflow component was removed after impossibility to perform second thrombectomy at 14 months. Over time the graft migrated distally (Figure 1), and patient developed skin ulceration and graft exposition (Figure 2). No important weight loss was noted. Arterial graft was removed surgically and she had kidney transplantation. Arterial graft removal when HeRO graft is abandoned should be considered.

Introduction: Cardiovocal or Ortner’s syndrome is a rare cause of vocal cord paralysis. Damage to the left recurrent laryngeal nerve may be caused by an aortic arch aneurysm, in even rarer cases. Clinical case: A 60-year-old woman presented with hoarseness lasting for six months. Paralysis of the left vocal cord was confirmed with laryngoscopy and an aortic arch aneurysm was diagnosed on chest CT. Despite correction of the aortic aneurysm, her hoarseness did not improve. Discussion: Mediastinal disease may cause vocal cord paralysis, due to the intrathoracic course of the recurrent laryngeal nerve. The assessment of the superior mediastinum on CT is mandatory in these cases. In cardiovocal syndrome, cardiovascular diseases damage the recurrent laryngeal nerve. Aortic aneurysms are a rare cause of Ortner’s, especially when they affect the distal portion of the aortic arch and stretch the left recurrent laryngeal nerve at the aortopulmonary window.

A 16-year-old female, without relevant previous medical history, presented with 1 year episodic and progressive hemoptysis. CT scan revealed an abnormal blood supply from the descending thoracic aorta to the left lower lobe, the later presenting with significant signs of hyperperfusion. Therapy consisted of ligation of the anomalous vessel followed by left lower lobe lobectomy. Lung sequestration is a rare congenital pulmonary malformation, mostly diagnosed in childhood. The typical symptoms are recurrent pulmonary infections or productive cough and only in rare situations severe hemoptysis occurs. Preoperative planning with CT or MR angiography is important to identify the aberrant blood supply. The treatment of choice is surgical ligation of the feeding vessel in combination with lung resection.

Background: It is particularly difficult to choose the appropriate prosthesis to treat infective endocarditis. Objectives: To investigate the outcomes after aortic valve replacement with a stented bioprosthesis (Trifecta) in patients with active or previous infective endocarditis. Methods: We performed a single-centre, retrospective study including consecutive patients with infective endocarditis who underwent aortic valve replacement between July 2011 and June 2019. Survival and reintervention were assessed as of December 2021. Hospital mortality was defined as death in-hospital or within 30-days of surgery. Kaplan-Meier method was used for time-to-event outcome assessment (all-cause mortality and reoperation). Data are median (minimum and maximum) or absolute (relative) frequencies. Results: We included 51 patients, median age of 69 (40 to 87) years, 78% male. The median follow-up time was 5.4 years and the maximum was 10 years. Most patients (71%) had native valve infective endocarditis and 16% had previous endocarditis. Surgery was urgent in 82%. Hospital mortality occurred in 10 patients (20%). After excluding these patients, 1-, 3-, 6-, and 9-years cumulative survival rates were 93%, 78%, 72%, and 72%, respectively. There were five bioprosthesis-related reoperations: 4 due to endocarditis at 1-year, 3-years, and 5-years on follow-up (n=1, 1 and 2, respectively) and 1 due to non-structural deterioration, 6-years after surgery. Conclusions: Despite the small sample size, this report supports a satisfactory performance profile of the Trifecta bioprosthesis in the treatment of infective endocarditis.

A The recent years of the cardiovascular medicine saw a rapid development of advanced imaging modalities. The new era of personalized medicine takes advantage of what can be interpreted from medical images, searching for underlying connections between image phenotyping and biological characteristics to support precise clinical decisions. The application of radiomics in cardiovascular imaging has lagged behind other fields, such as oncology. While the current interpretation of cardiac and vascular images mainly depends on subjective and qualitative analysis, radiomics uses advanced image analysis to extract numerous quantitative features from digital images that are unrecognizable to the naked eye. The goal of this narrative review is to highlight the main findings of the recent use of radiomic analysis in the cardiovascular field. English-language articles published in the database PubMed were used for this review. The keywords used in the search included radiomics, cardiovascular or cardiac or aortic. Radiomics is expected to contribute to a more precise phenotyping of the cardiovascular disease, which can improve diagnostic, prognostic, and therapeutic decision making in the near future.

Cardiac myxomas are the most common primary cardiac tumours in adults. Clinical presentation is variable, with few cases of infected myxomas reported in the literature. We describe a rare case of a 63-year-old patient who presented with splenic abscesses and a left atrial mass suggestive of emboligen myxoma. The patient underwent a successful emergency sur- gical excision of the atrial mass followed by splenectomy. Blood cultures were positive for Fusobacterium nucleatum, whereas the histopathological examination of the excised mass confirmed the presence of a myxoma with a marked inflammatory infiltrate. All these findings allowed us to confirm the diagnosis of definite infected myxoma. Some aspects related to the aetiology, diagnosis and management of this entity are discussed.
