ABSTRACT
BACKGROUND: The aim of this work was to evaluate the long-term patency of endografting in the treatment of popliteal artery aneurysms (PAAs) and to identify which factors may be predictors of graft occlusion. METHODS: All the patients who underwent endovascular repair of PAA were analyzed from 2006 until 2014 on the basis of symptoms, comorbidities, limb salvage, and long-term patency. The predictive value of the different variables was assessed in univariate analysis for primary patency and, for factors resulted significant, a multivariate analysis was performed. The Kaplan-Meier life table method was used to calculate patency and limb salvage. RESULTS: We treated 65 PAAs in 57 patients (53 men and 4 women). PAAs were symptomatic in 26 cases (40%) and 34% were the emergency cases; the mean aneurysm size was 33.8 ± 17 mm. Mean follow-up was 35 months ± 25. Graft occlusion occurred in 22 limbs (35%). We had 9 amputations (14.5%). The late conversion to open surgery was 6.4%. The cumulative estimated 60-month primary patency, secondary patency, and limb salvage were respectively 57% (standard error [SE] ±0.7), 73% (SE ±0.7), and 83% (SE ±0.5). We found that diabetes (hazard ratio [HR] 2.936, 95% confidence interval [CI] 0.993-8.683), associated percutaneous transluminal angioplasty (PTA) procedures (HR 2.534, 95% CI 1.115-5.757), symptoms (HR 2.492, 95% CI 1.127-5.510), and runoff scores (HR 2.069, 95% CI 0.942-4.544) were the most important risk factors for long-term patency at univariate analysis. When considering a multivariate analysis symptoms (HR 2.066, 95% CI 0.862-4.952) become the principal risk factor followed by diabetes (HR 1.808, 95% CI 0.531-6.157)], runoff scores (HR 1.716, 95% CI 0.757-3.893) and associated PTA procedures (HR 1.441, 95% CI 0.519-3.839), but no one reached a statistical significance. CONCLUSIONS: On the base of our experience it seems that several factors affect durability in PAA endovascular repair, especially the presence of acute symptoms, diabetes, and runoff. Therefore until further refined clinical studies, we believe that the actual role of this technique must be yet clarified.

Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms constituting less than 2% of all soft tissue tumors. They typically originate in the thoracic cavity, mainly in the pleura, but can also occur in other various sites such as lung parenchyma, pericardium, and bronchus. In this study, a 49-year-old non-smoking female with a history of allergies presented to our pulmonary clinic with a chronic cough. An explorative bronchoscopy revealed an intrabronchial mass in the left superior bronchi, and a 68 Ga-DOTATOC positron emission computed tomography suggested a carcinoid tumor. Subsequent pulmonary segmentectomy unveiled a well-circumscribed polypoid lesion diagnosed as a low-grade bronchus SFT through histopathological and immunohistochemical assessments. The patient was asymptomatic after surgical excision and showed no other lesion during the 6-month follow-up. The endobronchial location of SFT is uncommon, with only a few reported cases in the literature, underscoring the necessity of considering various differential diagnoses, including carcinoid, mucoepidermoid carcinoma, endobronchial pleomorphic adenoma, hamartoma, leiomyoma, and metastasis, depending on location and imaging features. This report underscores the importance of careful histological and immunohistochemical evaluation in understanding and appropriately stratifying the risk associated with polypoid lesions.

The role of immunotherapy in the multimodal treatment for pleural mesothelioma (PM) is still under investigation, particularly in the preoperative setting. Pathological complete response (pCR) has been previously described after chemotherapy and immunotherapy; however, there is no prior experience reported with immunotherapy alone before surgery. We report the case of a 58-year-old male with biphasic PM treated with immunotherapy, resulting in a major clinical partial response. Following a multidisciplinary evaluation between thoracic surgeons, medical oncologists, pathologists, radiologists and radiation oncologists, the patient underwent surgery with radical intent through a right extended pleurectomy/decortication (eP/D). Histopathological examination of the specimen confirmed a pathological Complete Response (pCR). This case supports the feasibility and potential efficacy of combining preoperative immunotherapy with surgery in the management of advanced PM.
ABSTRACT
We report the case of a 51-year-old woman, treated with radiotherapy at the age of two years, for a pulmonary sarcoma. Subsequently she developed severe aortic stenosis and bilateral ostial coronary artery disease, symptomatic for dyspnea (NYHA III functional class). Due to the prohibitive surgical risk, she underwent successful stenting in the right coronary artery and left main ostia with drug eluting stents and, afterwards, transcatheter aortic valve replacement with transfemoral implantation of a 23 mm Edwards SAPIEN XT valve. The percutaneous treatment was successful without complications and the patient is in NYHA II functional class at 2 years' follow-up, fully carrying out normal daily activities.
ABSTRACT
We report the case of a 78-year-old female who presented to our hospital with signs of hemorrhagic shock and breathlessness. A transthoracic echocardiography demonstrated pericardial effusion. Computed tomography of the chest showed a penetrating atherosclerotic ulcer of the aortic arch with an intramural hematoma of the ascending and descending aorta. Endovascular repair with stent-grafting was urgently performed and a pericardial window placement was done to reduce mediastinal bleeding.
