RESUMEN

Melanoma in situ of the nipple is an uncommon diagnosis, with only a few reports in the literature. Due to the variety of pathologies that can affect the nipple-areola complex, the diagnosis can be challenging. In this case report we describe a patient with cosmetic bilateral breast implants who presented with eczema of the left nipple-areola complex and suspicious microcalcifications in the lower inner quadrant of the ipsilateral breast on mammography, subsequently diagnosed with nipple melanoma and concomitant ductal carcinoma in situ.

RESUMEN

BACKGROUND: This study evaluates the procedural efficacy and patient experience of Contrast Enhanced Mammography (CEM)-guided biopsies performed in a prone position using the Giotto Class 30,000 system. The emphasis is on the procedural advantages and clinical outcomes for "enhancing-only lesions" (EOLs). METHODS: A retrospective analysis of 524 CEM examinations conducted from December 2023 to June 2024 at a tertiary referral center was performed. Patients referred for pre-surgical staging or evaluation of inconclusive findings from conventional imaging were included. The study utilized dual-energy imaging and vacuum-assisted biopsy techniques, focusing on patients with at least one EOL identified in their initial CEM. Exclusions were based on the absence of a primary or follow-up CEM conducted at our facility Endpoints of this work included procedure efficiency which was evaluated in terms of technical success (biopsy completion with adequate sampling), dose distribution and timing and detection of additional lesions and patients' comfort evaluation, based on the rate of complications (hematomas) and procedure interruption due to patients' specific request or fainting events. RESULTS: Among the evaluated cases, 37 EOLs were biopsied. The average procedure time was 15.8 min. Biopsies were successfully completed in 100% of cases. However, complications occurred in 27% of cases, primarily as hematomas and a significant histological finding rate of 97.3% was recorded. CONCLUSIONS: The use of the Giotto Class 30,000 system for CEM-guided biopsies in a prone position demonstrated high procedural success and was well-tolerated by patients, highlighting its potential to enhance procedural comfort and efficiency. These preliminary results validate the innovative approach, though further studies are required to solidify these findings and explore long-term outcomes.

RESUMEN

Neoadjuvant chemotherapy (NAT) plays a crucial role in breast cancer (BC) treatment, both in advanced BC and in early-stage BC, with different rates of pathological complete response (pCR) among the different BC molecular subtypes. Imaging monitoring is mandatory to evaluate the NAT efficacy. This study evaluates the diagnostic performance of Contrast-Enhanced Mammography (CEM) in BC patients undergoing NAT. This retrospective two-center study included 174 patients. The breast lesions were classified based on the molecular subtypes in hormone receptor (HR+)/HER2-, HER2+, and triple-negative breast cancer (TNBC). The histopathological analysis performed following surgery was used as a reference standard for the pCR. Sensitivity, specificity, PPV, and NPV were measured overall and for the different subtypes. We enrolled 174 patients, 79/174 (46%) HR+/HER2-, 59/174 (33.9%) HER2+, and 35/174 (20.1%) TNBC; the pCR was found in 64/174 (36.8%), of which 57.1% were TNBCs. In the total population, the CEM sensitivity and specificity were 66.2% and 75.2%, with a PPV of 61.4% and an NPV of 78.8%. The highest specificity (80.9%) and NPV (91.7%) were found in HR+/HER2-, while the highest sensitivity (70%) and PPV appeared (73.7%) in TNBC. The results indicate that CEM is a valid tool to assess the pCR, with different performances among the subtypes of BC.

RESUMEN

PURPOSE Renal artery aneurysms (RAAs) are rare in the general population, although the true incidence and natural history remain elusive. Conventional endovascular therapies such as coil embolization or covered stent graft may cause sidebranches occlusion, leading to organ infarction. Flow-diverters (FD) have been firstly designed to treat cerebrovascular aneurysms, but their use may be useful to treat complex RAAs presenting sidebraches arising from aneurysmal sac. To evaluate mid-term follow-up (FUP) safety and efficacy of FD during treatment of complex RAAs. METHODS Between November 2019 and April 2020, 7 RAAs were identified in 7 patients (4 men, 3 women; age range 55-82 years; median 67 years) and treated by FD. Procedural details, complications, morbidity and mortality, aneurysm occlusion and segmental artery patency were retrospectively reviewed. Twelve months computed tomography angiography (CTA) FUP was evaluated for all cases. RESULT Deployment of FD was successful in all cases. One intraprocedural technical complication was encountered with one FD felt down into aneurism sac which requiring additional telescopic stenting. One case at 3 months CTA FUP presented same complication, requiring same rescue technique. At 12 months CTA FUP 5 cases of size shrinkage and 2 cases of stable size were documented. No rescue surgery or major intraprocedural or mid-term FUP complication was seen. CONCLUSION Complex RAAs with two or more sidebranches can be safely treated by FD. FD efficacy for RAA needs a further validation at long term FUP by additional large prospective studies.

RESUMEN

Breast cancer (BC) has overtaken lung cancer as the most common cancer in the world and the projected incidence rates show a further increase. Early detection through population screening remains the cornerstone of BC control, but a progressive change from early diagnosis only-based to a personalized preventive and risk-reducing approach is widely debated. Risk-stratification models, which also include personal lifestyle risk factors, are under evaluation, although the documentation burden to gather population-based data is relevant and traditional data collection methods show some limitations. This paper provides the preliminary results from the analysis of clinical data provided by radiologists and lifestyle data collected using self-administered questionnaires from 5601 post-menopausal women. The weight of the combinations of women's personal features and lifestyle habits on the BC risk were estimated by combining a model-driven and a data-driven approach to analysis. The weight of each factor on cancer occurrence was assessed using a logistic model. Additionally, communities of women sharing common features were identified and combined in risk profiles using social network analysis techniques. Our results suggest that preventive programs focused on increasing physical activity should be widely promoted, in particular among the oldest women. Additionally, current findings suggest that pregnancy, breast-feeding, salt limitation, and oral contraception use could have different effects on cancer risk, based on the overall woman's risk profile. To overcome the limitations of our data, this work also introduces a mobile health tool, the Dress-PINK, designed to collect real patients' data in an innovative way for improving women's response rate, data accuracy, and completeness as well as the timeliness of data availability. Finally, the tool provides tailored prevention messages to promote critical consciousness, critical thinking, and increased health literacy among the general population.

RESUMEN

PURPOSE: Inflammatory pseudotumors of the liver (IPTL) are not exceptional benign lesions with various etiologies, histology, and imaging appearances. The incomplete knowledge of this pathology and the wide polymorphism sometimes resembling malignancy often induce long and expensive diagnostic flow, biopsy and occasionally unnecessary surgery. We propose a systematic revision of MRI literature data (2000-2021) with some narrative inserts and 10 new complete MRI cases, with the aim of organizing the data about IPTL and identifying some typical features able to improve its diagnosis from imaging. METHODS: We performed a systematic revision of literature from 2000 to 2021 to obtain MRI features, epidemiological, and clinical data of IPTL. The basic online search algorithm on the PubMed database was "(pseudotumor) AND (liver) AND (imaging)." Quality assessment was performed using both scales by Moola for case report studies and by Munn for cross-sectional studies reporting prevalence data. A case-based retrospective study by collecting patients diagnosed with IPTL from three different university hospitals from 2015 to 2021 was done as well. Only cases with MR examinations complete with T1/T2/contrast-enhanced T1/Diffusion-Weighted (W) images and pathology-proven IPTL were selected. RESULTS: After screening/selection 38 articles were included for a total of 114 patients. In our experience we selected 10 cases for a total of 16 IPTLs; 8 out of 10 patients underwent at least 1 MRI follow-up. Some reproducible and rather typical imaging findings for IPTL were found. The targetoid aspect of IPTL is very frequent in our experience (75% on T1W, 44% on T2W, 81% on contrast-enhanced T1W (at least one phase), 100% on Diffusion-W images) but is also recurrent in the literature (6% on T1W, 31% on T2W, 51% on CE-T1W (at least one phase), 18% on Diffusion-W images, and 67% on hepatobiliary phase). In our experience, Apparent Diffusion Coefficient map values were always equal to or higher than those of the surrounding parenchyma, and at MRI follow-up, nodule/s disappeared at first/second control, in six patients, while in the remaining 2, lesions persisted with tendency to dehydration. CONCLUSION: A targetoid-like aspect of a focal liver lesion must raise diagnostic suspicion, especially if IgG4-positive plasma is detected. MRI follow-up mainly shows the disappearance of the lesion or its reduction with dehydration.

RESUMEN

OBJECTIVE: This study aims to describe the results achieved in the management of rectus sheath hematoma (RSH) using glue embolization. METHOD: Data about all consecutive patients presenting with RSH, between January 2005 and December 2020 were retrospectively reviewed. RSHs were classified according to the Berna CT scan Classification. Clinical and technical outcomes were evaluated during in-hospital period and 1-month follow-up. RESULTS: Among 74 patients presenting with RSH, CTA revealed an active bleeding in 61 (n = 42, 69% women; median age = 68.8 y range: 47-91). 19 cases of type 1 RSH (25.7%), under anticoagulation therapy and hemodynamically stable, were successfully managed conservatively. Conversely, endovascular embolization with cyanoacrylate glue diluted with ethiodized oil (Lipiodol Ultrafluid, Guerbet, France) was needed in n = 42 (56.8%) patients, in 16 cases after failure of conservative management; a single session of percutaneous glue embolization was adequate to achieve technical and clinical success in all patients with stabilization or progressive improvement of hemoglobin values after procedure (7.1 + 1.8 g/dL pre-procedure vs 11.1 + 1.6 g/dL post-procedure). No major complications occurred. Two minor complications were reported: 1 case (2.4%) of puncture site-related complication (local self-limiting hematoma) and 1 case (2.4%) of post-embolization syndrome (abdominal pain) spontaneously regressive. The median hospital stay was 7 d. At 30-day follow-up, 2 patients (2.7%) died of multiorgan failure. CONCLUSIONS: In the management of RSH, glue embolization was shown to be safe and efficacious. Glue allowed the immediate occlusion of both the "front and back doors" of bleeding without the need to reach the bleeding point, preventing potentially life-threatening recurrence.

RESUMEN

OBJECTIVES: To investigate the outcomes of patients with calcific lesions in the common femoral artery undergoing endovascular procedures with atherectomy device and scoring balloon angioplasty combined with treatment of steno-occlusive disease of the remaining arterial districts of the lower limb. METHODS: Between January 2015 and December 2018, 11 diabetic patients at high risk for "major amputation", with calcific lesions of the common femoral artery and ischemic ulcers requiring endovascular treatment were retrospectively evaluated. Technical success was defined as revascularization of the common femoral artery with a residual stenosis lower than 30%. Primary endpoints were an immediate increase of perilesional transcutaneous oxygen pressure (TCPO2) > 40 mmHg, ulcerative lesions improvement up to healing or skin flaps re-epithelialization after minor amputation, limb rescue with rejected major amputation, and resolution of rest pain if present. RESULTS: The success rate of the revascularization procedures was 100%. No patient underwent surgical conversion. One case of peri-operative bleeding at the brachial access site was observed. There were no cases of arterial dissection or undesired distal embolization. The average baseline value of perilesional TCPO2 was 21.8 ± 9.2 mmHg. The mean TCPO2 value was 57.4 ± 7.2 mmHg three days after the procedure (P < 0.05), and 51.2 ± 9.8 mmHg 15 days after (P < 0.05). Minor amputations were performed in five patients with advanced ulcerative lesions. No major amputations were performed in the follow-up period. At 14 months follow-up, one patient developed new occlusion of the CFA for extension from the external iliac artery and underwent a new endovascular procedure. We observed an overall primary patency rate of 91% and a primary assisted patency rate of 100% in our 18-month follow-up. CONCLUSIONS: Endovascular approach for severely calcified atherosclerotic lesions of the common femoral artery seems to represent a valid therapeutic option associated with promising results in terms of clinical outcome and low complication rates.

RESUMEN

OBJECTIVE: The objective is to report a single centre experience in the embolization of visceral artery pseudoaneurysms with N-butyl-cyanoacrylate-methacryloxy sulfolane (NBCA-MS). METHODS: A retrospective observational cohort study was conducted on data about all consecutive patients treated for visceral artery pseudoaneurysms in the Interventional Radiology Unit of SS Annunziata Hospital, in Taranto (Italy) between January 2016 and July 2020. Only patients treated with NBCA-MS embolization were included. Clinical and technical outcomes were evaluated during in-hospital stay and at 3-month follow-up by computed angiotomography (CTA). RESULTS: Among 89 patients undergoing treatment for visceral artery pseudoaneurysm, a total of 58 (65.2%) patients (n = 32, 55.2% men; median age 45.8 years, range: 35-81) treated with NBCA-MS only were enrolled. Pseudoaneurysms were located in the renal artery (n = 18 cases, 31%), in the splenic artery (n = 27, 46.6%), in the intra-parenchymal hepatic artery (n = 3, 5.2%), in the common hepatic artery (n = 4, 6.9%) or in the pancreatic artery (n = 6, 10.3%). N-butyl-cyanoacrylate was diluted 1:1 with Lipiodol ultra-fluid, and mean volume injected was 0.6 ± 0.3 mL (range: 0.2-2.8 mL). Embolization was technically and clinically successful in all patients (n = 58, 100%) with an immediate total thrombosis of the pseudoaneurysm at the completion angiography. No systemic complications were noted in all cases. Five cases (8.6%) of non-target vessel embolization occurred without any clinical complication. No pseudoaneurysm recurrence was detected at the CTA control 1 day postoperatively. In one case (1.7%), a recurrence was detected 4 days after the initial treatment and successfully managed by a repeated NBCA-MS embolization. During the hospital stay, 56 patients recovered well but 2 (3.4%) died from multi-organ failure not related to the embolization. No recurrences were detected at the 3-month postoperative CTA in the remaining patients. CONCLUSIONS: In properly selected patients affected with visceral artery pseudoaneurysms, NBCA-MS represents a definitive and safe embolization agent.

RESUMEN

We report the case of a 38-year-old woman who underwent orthotopic 'split' liver transplant, complicated by hepatic artery thrombosis on the first postoperative day. The patient was successfully treated with an endovascular approach by mechanical thromboaspiration of the hepatic artery, using neurovascular devices, angioplasty and stenting at the site of the surgical anastomosis.

RESUMEN

An 83-year-old man experienced left upper limb uncontrolled movements preceded by intense gasping during night rest, which progressed to unconsciousness and respiratory arrest requiring intubation. He was diagnosed with acute stroke due to distal occlusion of the basilar artery and received indication for endovascular thrombectomy. Standard endovascular approach includes percutaneous puncture of the femoral or radial arteries; however, the presence of unfavourable vascular anatomies (stenotic origin and tortuosity) did not allow catheterisation of the intracranial vessels through conventional access, and based on the consistent time lapse from onset of symptoms and deterioration of the clinical condition, a direct right vertebral artery ultrasound-guided puncture was performed. After one attempt of a triaxial technique, a complete recanalisation of the basilar artery and of its distal branches was achieved. Direct percutaneous puncture of the vertebral artery represents a rescue access strategy for treatment of posterior circulation stroke when other routes are not feasible.

RESUMEN

The liver is the major drug-metabolizing and drug-detoxifying organ. Many drugs can cause liver damage through various mechanisms; however, the liver response to injury includes a relatively narrow spectrum of alterations that, regardless of the cause, are represented by phlogosis, oxidative stress and necrosis. The combination of these alterations mainly results in three radiological findings: vascular alterations, structural changes and metabolic function reduction. Chemotherapy has changed in recent decades in terms of the drugs, protocols and duration, allowing patients a longer life expectancy. As a consequence, we are currently observing an increase in chemotherapy-associated liver injury patterns once considered unusual. Recognizing this form of damage in an early stage is crucial for reconsidering the therapy regimen and thus avoiding severe complications. In this frontier article, we analyze the role of imaging in detecting some of these pathological patterns, such as pseudocirrhosis, "yellow liver" due to chemotherapy-associated steatosis-steatohepatitis, and "blue liver", including sinusoidal obstruction syndrome, veno-occlusive disease and peliosis.

RESUMEN

OBJECTIVES: To compare three commonly used large-bore aspiration catheters in terms of final successful recanalization rate and first-passage successful and complete recanalization rates (the so called "first-passage effect"). MATERIALS AND METHODS: it is an observational retrospective multicenter study conducted in three Italian high-volume tertiary stroke centers between January 2017 and May 2019. The study population included all consecutive patients with an ischemic stroke due to middle cerebral artery occlusion (M1 segment only) that underwent intra-arterial mechanical thrombectomy with contact aspiration as first-line strategy within 24 hours from symptoms onset. RESULTS: Three hundred twenty-one patients were included in the study. Multivariable logistic regression analysis comparing the three catheters revealed no differences in terms of successful recanalization. Sofia 6 Plus catheter was associated with better first-passage successful recanalization [OR, 9.09; 95% CI, 2.66-31.03] (p<0.001) and first-passage complete recanalization [OR: 3.73; 95% CI: 1.43-9.72] (p=0.007) whereas rt-PA was associated with worse first-passage recanalization [OR: 0.52; 95% CI: 0.29-0.93] (p=0.028). CONCLUSIONS: No differences between the three catheters were reported in terms of successful recanalization. Sofia 6 Plus has proven to be superior in achieving both successful and complete first-passage recanalization. Conversely, rt-PA was found to be a negative predicting factor of first-passage effect.

RESUMEN

BACKGROUND: To assess technical and clinical outcomes of an intermediate bore aspiration catheter (AXS Catalyst 5; Stryker) as front-line therapy for M2-M3 acute occlusions. METHODS: A multicentric, retrospective data collection of patients with symptomatic M2-M3 ischemic stroke, treated with direct aspiration first-pass technique was obtained. Time to recanalization, first attempt recanalization, and number of attempts were recorded. Successful recanalization was defined as a modified thrombolysis in cerebral infarction score ≥2b; incidence of procedure-related complications was recorded. National Institutes of Health Stroke Scale at discharge and modified Rankin Scale score at 90 days were evaluated by a dedicated neurologist. RESULTS: A total of 44 acute occlusions of distal M2-M3 segment were treated with a direct aspiration first-pass technique using CAT 5 (mean age 68,4 years). Median NIHSS at baseline was 10. Overall modified thrombolysis in cerebral infarction score ≥2b was obtained in 90,9% of patients with mean time to recanalization of 49,7 minutes and a mean of 1.6 attempts. First-attempt recanalization with CAT 5 was obtained in 52,3% of patients with a mean time to recanalization of 29.2 min. A stent retriever with proximal aspiration was incorporated as a rescue device in 3 cases. No major complications was detected. The median National Institutes of Health Stroke Scale score at discharge was 4. At 90 days, a modified Rankin Scale score of 0-2 was achieved in 70,5% of patients. CONCLUSIONS: ADAPT technique with the intermediate aspiration catheter CAT 5 system achieves successful revascularization and functional independence for patients with acute ischemic stroke secondary to distal M2 occlusions.

RESUMEN

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stimulates pro-thrombotic changes. This, combined with its tropism for endothelium and lung structures, may explain its association with thrombotic events, reduction of pulmonary gas exchange, acute respiratory distress syndrome (ARDS) and a composite end-point (intensive care unit, invasive ventilation, death). This study aims to highlight the correlation between elevated D-dimer (an indirect thrombosis marker) and the increased rate of poor prognosis-associated conditions, and to introduce D-dimer-labelled anticoagulant administration as a potentially useful tool to prevent complications and positively influence coronavirus disease 2019 (COVID-19) course. METHODS: An online database search (PubMed, Google Scholar, Scopus, Web of Science and Cochrane) was performed between 13 March and 10 April 2020. The most relevant keywords were "D-dimer", "SARS-CoV-2", "COVID-19", "thrombosis" and "ARDS". Selection was independently conducted by three reviewers. References and previews of accepted articles were evaluated. Data inclusion/extraction inaccuracy was limited by the work of three reviewers. Selection bias reduction was addressed by thoughtfully designing the search protocol. Quality assessment was performed with the Newcastle-Ottawa Scale. The systematic review protocol was not registered because we anticipated the very limited available evidence on the topic and due to the urgency of the study. RESULTS: 16 studies were evaluated. Good-quality criteria were reached in 13 out of 16 studies. D-dimer was increased and significantly higher in COVID-19 patients compared with healthy controls, in COVID-19 patients with severe disease or a composite end-point compared with non-severe disease, in ARDS compared with non-ARDS patients and in deceased ARDS patients compared with ARDS patients who survived (all p<0.001). COVID-19 patients treated with anticoagulants demonstrated lower mortality compared with those not treated (p=0.017). CONCLUSIONS: Correlations exist between COVID-19 infection, severe elevation of D-dimer levels, and increase in the rate of complications and composite end-point. The appropriateness of early and continuous D-dimer monitoring and labelled anticoagulation as management tools for COVID-19 disease deserves accurate investigation, to prevent complications and reduce interventions.

RESUMEN

PURPOSE: To clarify the role of endovascular treatment in patients with Critical Hand Ischemia of the distal upper extremity. METHODS: From January 2012 to January 2017, 18 dialyzed patients presented chronic critical hand ischemia; 6 patients had a chronic occlusion of the ulnar artery and radial artery stenosis, 5 patients had a chronic occlusion of the radial artery and ulnar artery stenosis, 4 patients presented multiple stenosis of the ulnar, radial and interosseous arteries, 2 patients had only ulnar artery occlusion while one patient presented only radial artery occlusion. All patients underwent duplex ultrasound and a subsequent brachial angiography, in order to evaluate the distal run-off circulation. Revascularization was achieved via antegrade brachial puncture in all patients, with retrograde approach in 4 patients, with distal retrograde puncture in 3 patients and in one patient with loop technique. RESULTS: No complications were observed during the periprocedural follow-up. One patient was not successfully revascularized (technical success rate: 94.4%). The patient had no direct flow after ulnar artery angioplasty. The procedure was clinical effective in 15 patients (clinical success rate: 83.3%). Clinical evaluation and Duplex-US were performed in the follow up period. TcpO2 evaluated in the perilesional skin surface increased from 20.2 ± 6.5 mmHg to 53.8 ± 13.1 mmHg in the follow up period (P < .01). We observed an improvement of pain, ulcers and infection healing in all treated remaining patients during the postoperative period.

RESUMEN

Introduction: The Mediterranean Diet (MD) is useful in the prevention of overweight, obesity and metabolic disease. High Quality-Extra Virgin Olive Oil (HQ-EVOO), an essential component of this diet, exerts protective effects against chronic diseases. Gut Microbiota (GM), recognized as a key factor in driving metabolic activities, is involved in the regulation of host immunity. Lactic Acid Bacteria (LAB) and their probio-active cellular substances produce beneficial effects in the gastrointestinal tract. Materials and Methods: Eighteen overweight/obese subjects (cases, BMI ≥25 kg/m2) and 18 normal weight controls (BMI 18.5-24.9 kg/m2) were fed with MD enriched with 40 g/die HQ-EVOO for three months. Feces and blood samples were collected at time 0 (T0) and after three months (T1) for LAB composition, oxidative stress, metabolic and inflammation parameter determinations. Results: Myeloperoxidase and 8-hydroxy-2-deoxyguanosine, markers of inflammation and oxidative stress, were significantly decreased after MD rich in HQ-EVOO both in controls and in cases. Proinflammatory cytokines levels were significantly decreased in cases in comparison to controls, while IL-10 and adiponectin were significantly increased in cases. LAB's rpoB copies/ng of DNA increased 55.6 folds in cases compared to their baseline after MD rich in HQ-EVOO. MD rich in HQ-EVOO increased adiponectin and IL-10 concentration in overweight/obese subjects and decreased oxidative stress and inflammation parameters and at the same time, increased LAB number in GM. Discussion: Our results indicate that MD rich in HQ-EVOO induces an increase of LAB in GM and could have a potential role in the prevention of inflammation.

RESUMEN

BACKGROUND: Endovascular coiling is generally considered as an effective treatment option for ruptured intracranial aneurysms. Increasing operator experience and quality of tools determined an improvement of endovascular cerebral aneurysms' treatment. However, procedure-related complications still occur. The purpose of this study is to report a series of rescue stenting procedures with the Neuroform Atlas (NA) open-cell stent, for intraprocedural complications during coil embolization in patients with ruptured intracranial aneurysms. METHODS: Between April 2016 and January 2018, 12 consecutive coil protrusions that occurred during ruptured aneurysms' embolizations were rescued using NA stenting together with tirofiban therapy. Follow-up was performed with initial magnetic resonance angiography (MRA) at 1 month and then MRA plus standard digital subtraction angiography at 11-13 months after the procedure. RESULTS: Technical success was achieved in 100% of patients. No NA stent delivery/deployment complication occurred. Initial MRA showed complete occlusion of the aneurysm, with evidence of blood flow into parent vessels in 12 out of 12 cases. At 11-13 months, MRA and digital subtraction angiography showed 10 complete occlusion cases and 1 partial occlusion case. At 2 months, 1 death occurred due to subarachnoid hemorrhage. CONCLUSIONS: The open-cell NA stent represents a rescue option for coil protrusion during endovascular treatment of ruptured intracranial aneurysms allowing regular restoration of blood flow and minimizing thromboembolic events.

RESUMEN

Dietary habits are widely reported to play a primary role in the occurrence of coronary artery disease (CAD). Cardiac rehabilitation is a multidisciplinary intervention that includes nutritional education. Proper nutrition plays an important role in cardiovascular health outcomes and in decreasing morbidity and mortality of cardiovascular diseases (CVD) as highlighted in the literature. The aim of this study was to assess the efficacy of an educational program to improve the diet of cardiac rehabilitation patients compared to usual treatment. 160 patients with CAD, (124 M, 36 F) were randomized into two groups. Data analysis was conducted on 133 patients (11 % dropped out). All enrolled patients attended two educational seminars about proper nutrition and cardiovascular prevention, and completed a questionnaire about dietary habits (before CAD). The Body Mass Index (BMI) was calculated, and basal glycaemia and plasma lipids were assessed at the beginning and at the end of the study (12 months after hospital discharge). The intervention group patients underwent a mid-term evaluation of nutrient intakes, BMI, and received a personalized educational reinforcement by a dietitian. At the end of the study, the intervention group was shown to have significantly reduced their daily caloric intake (reduction of total proteins, total fat, carbohydrate, alcohol), and showed a significant reduction of weight and BMI compared to the control group. Individual nutritional counseling session as a reinforcement of a standard educational program is effective in reducing caloric intake and BMI, which may reduce cardiovascular risk factors in cardiovascular patients.
