- Aneurismas das Artérias Viscerais: Alternativa TerapêuticaPublication . Vasconcelos, L; Silva, S; Garcia, AC; Medeiros, D; Albuquerque e Castro, J; Mota Capitão, LThe authors report two cases in which stent grafts were used to treat visceral artery aneurysms. Case number 1 was a 42-year old woman with a history of renal colic who was found to have a right renal artery aneurysm. Two 6-mm x 20-mm Wallgraft endoprosthesis (Boston Scientific, Watertown, Mass) were placed across the aneurysm neck. Case number 2 was a 72 year-old woman with a past medical history significant for hepatic angioma and hypothyroidism. She was found to have a superior mesenteric artery aneurysm that was treated with a 6-mm x 17-mm Jostent stent graft (Jomed, GmbH, Ra). In both cases the aneurysm was completely excluded and distal end-organ flow preserved. Stent graft placement is a safe and effective treatment for visceral artery aneurysms. If this approach proves durable and reproducible, it can become the method of choice for the management of visceral artery aneurysms in selected patients.
- Consulta de Úlcera de Perna do Hospital de Santa MartaPublication . Garcia, AC; Vasconcelos, L; Valentim, H; Gonçalves, F; Castro, JM; Ferreira, E; Albuquerque e Castro, J; Mota Capitão, LLeg ulcers constitute a highly prevalent pathology in society, and are particularly common in the Angiology and Vascular Surgery outpatient clinic. The prevalence of these patients in this Department result from the fact that 70% of them display superficial and/or deep venous insufficiency of the lower limbs. To address this problem and optimize the therapeutic approaches available to the Chronic Leg Ulcer (CLU) patients, the Department of Angiology and Vascular Surgery has created, in March 2005, an appointment specific to CLU patients. An evaluation protocol was developed, including ulcer characterization, standardization of the conservative treatment, followed by surgical intervention, whenever required. The results obtained were evaluated 18 months after the onset of this protocol. Analysis of the results revealed that the majority of the patients responded positively to the new therapeutic approach, with closure of the ulcer in 43% of the patients and a significant improvement detected for an additional 30%. Furthermore, it was observed that a detailed evaluation of these patients should be regarded as a whole, followed by a standardized and targeted approach, resulting in a particularly successful approach on the treatment of this pathology.
- Falso Aneurisma Traumático da Aorta Infrarenal. A Propósito de um Caso ClínicoPublication . Albino, JP; Garcia, AC; Meireles, NAbdominal aortic pseudoaneurysms are rare, particularly when they are related to blunt abdominal trauma. The authors report the clinical case of a 65 years old man with an abdominal aortic pseudoaneurysm related to a blunt abdominal trauma, that occurred three years ago. The patient complained of a diffuse abdominal pain, increased while walking. The diagnosis was confirmed by angiography and by angio-CT. An aortic resection and interposition graft was performed, according to the age of the patient and the low operative risk. A discussion on the therapeutic option was made, followed by a revision of the literature on the subject, and the authors conclude by emphasizing the need of a detection of this type of pathology, particularly in patients who had suffered in the past violent trauma.
- Seroprevalence of SARS-CoV-2 Infection in Portugal in May-July 2020: Results of the First National Serological Survey (ISNCOVID-19)Publication . Kislaya, I; Gonçalves, P; Barreto, M; Sousa, R; Garcia, AC; Matos, R; Guiomar, R; Rodrigues, AP; Dias, AIntroduction: The aim of this study was to estimate and describe the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) specific antibodies (immunoglobulin M and/or immunoglobulin G) in Portugal in May-July 2020. Material and methods: A cross-sectional seroepidemiological survey was developed after the peak of the first epidemic wave on a sample of 2301 Portuguese residents, aged 1 year or older. Survey sample was selected using a two-stage stratified non-probability sampling design (quota sampling). SARS-CoV-2 immunoglobulin M and immunoglobulin G antibodies were measured in serum samples by enzyme-linked immunosorbent assay. Seroprevalence estimates of immunoglobulin M and/or immunoglobulin G and 95% confidence intervals were stratified by sex, age group, health region and education. Results: Overall, seroprevalence was 2.9% (95% confidence interval: 2.0% - 4.2%). Higher prevalence rates were observed in male (4.1%, 95% confidence interval: 2.6% - 6.6%) and those with secondary education (6.4%, 95% confidence interval: 3.2% - 12.5%). Differences in seroprevalence by age group and region were not statistically significant. Discussion: The estimated seroprevalence of SARS-CoV-2 was higher than the cumulative incidence reported by the National Surveillance System but far from necessary to reach herd immunity. Conclusion: Our results support limited extent of infection by SARS-CoV-2 in the study population possibly due to early lockdown measures implemented in Portugal and support the need to continue monitoring of SARS-CoV-2 seroprevalence in order to increase our knowledge about the evolution of the epidemic and to estimate the proportion of the susceptible population over time.
- Tumores do Corpo Carotídeo. Experiência de um Serviço no Diagnóstico e Tratamento nos Últimos 10 AnosPublication . Valentim, H; Gonçalves, H; Vasconcelos, L; Garcia, AC; Silva Castro, J; Ferreira, E; Albuquerque e Castro, J; Mota Capitão, LINTRODUCTION: Carotid body tumours (CBT) are neoplasms that develop from paragangionic cells of this structure. They are rare, with an estimated incidence of 1:30000 and can be associated with other neuro-endocrine neoplasia. The authors report their experience in the management of the disease, in the last 10 years. MATERIAL AND METHODS: Eight patients (with eight tumours) were treated, all submitted to tumour resection. 75% were female and the mean age was 56 years. We report a 12,5% incidence of neurological sequelae from surgery, and no mortality. In the follow-up (which varied between 1 and 10 years), no local or contralateral recurrence or metastasis were registered. Also, we did not found family cases of this disease. CONCLUSIONS: The authors noticed an unusually high proportion of female patients. The tumour resection was curative in all patients, with a rate of neurological complications inferior to that reported in other published series. These neurological sequelae were reported in patients with large tumours, thus reinforcing the outmost importance of an early diagnosis. Pre-operative selective embolization of these tumours can be helpful in the resection of large tumours, allowing a potential reduction in neurological complications.
