Uma Complicação Grave da Embolização das Artérias Uterinas

Uterine artery embolisation has been used as a therapeutic alternative for symptomatic uterine myomas. It is considered a safe and effective procedure, with very few cases published involving complications. The authors present a case of a 35-year-old nulliparous woman with an intramural myoma with 161x143x85mm, submitted to an uterine artery embolisation complicated by uterine necrosis. A hysterectomy was performed. This casereport reinforces the idea that artery embolization is not a riskfree procedure and serious complications may occur. Therefore, patients should be carefully selected.

The Role of Accessory Obturator Arteries in Prostatic Arterial Embolization

In 9 of 491 patients (1.8%) who underwent prostatic arterial embolization (PAE) for benign prostatic hyperplasia from March 2009-November 2013, prostatic arteries arose from the external iliac artery via an accessory obturator artery (AOA). Computed tomography angiography performed before the procedure identified the variant and allowed planning before the procedure. The nine AOAs were catheterized from a contralateral femoral approach. Bilateral PAE was technically successful in the nine patients. There was a mean decrease in international prostate symptom score of 6.5 points and a mean prostate volume reduction of 15.1% (mean follow-up, 4.8 mo) in the nine patients.

Lower Atherosclerotic Burden in Familial Abdominal Aortic Aneurysm

OBJECTIVE: Despite the apparent familial tendency toward abdominal aortic aneurysm (AAA) formation, the genetic causes and underlying molecular mechanisms are still undefined. In this study, we investigated the association between familial AAA (fAAA) and atherosclerosis. METHODS: Data were collected from a prospective database including AAA patients between 2004 and 2012 in the Erasmus University Medical Center, Rotterdam, The Netherlands. Family history was obtained by written questionnaire (93.1% response rate). Patients were classified as fAAA when at least one affected first-degree relative with an aortic aneurysm was reported. Patients without an affected first-degree relative were classified as sporadic AAA (spAAA). A standardized ultrasound measurement of the common carotid intima-media thickness (CIMT), a marker for generalized atherosclerosis, was routinely performed and patients' clinical characteristics (demographics, aneurysm characteristics, cardiovascular comorbidities and risk factors, and medication use) were recorded. Multivariable linear regression analyses were used to assess the mean adjusted difference in CIMT and multivariable logistic regression analysis was used to calculate associations of increased CIMT and clinical characteristics between fAAA and spAAA. RESULTS: A total of 461 AAA patients (85% men, mean age, 70 years) were included in the study; 103 patients (22.3%) were classified as fAAA and 358 patients (77.7%) as spAAA. The mean (standard deviation) CIMT in patients with fAAA was 0.89 (0.24) mm and 1.00 (0.29) mm in patients with spAAA (P = .001). Adjustment for clinical characteristics showed a mean difference in CIMT of 0.09 mm (95% confidence interval, 0.02-0.15; P = .011) between both groups. Increased CIMT, smoking, hypertension, and diabetes mellitus were all less associated with fAAA compared with spAAA. CONCLUSIONS: The current study shows a lower atherosclerotic burden, as reflected by a lower CIMT, in patients with fAAA compared with patients with spAAA, independent of common atherosclerotic risk factors. These results support the hypothesis that although atherosclerosis is a common underlying feature in patients with aneurysms, atherosclerosis is not the primary driving factor in the development of fAAA.

Fístulas Arteriovenosas Renais. Tratamento Conservador por Embolização Arterial

Fazem-se considerações gerais sobre as FAV, incidindo particularmente nas renais. Descrevem-se dois casos de FAV renais traumáticas com hematúria, tratadas por embolização.

Síndrome Febril e Coma. Considerações a Propósito de Um Caso Clínico

A endocardite infecciosa é relativamente pouco frequente na idade pediátrica, mas a sua morbilidade e mortalidade são elevadas. Os autores descrevem um caso clínico de endocardite infecciosa aguda por Staphylococcus aureus numa criança de 5 anos de idade, sem factores de risco conhecidos, diagnosticada na sequência de complicações neurológicas (degradação súbita do estado de consciência e sinais neurológicos focais) resultantes de enfarte talâmico bilateral. A localização da lesão na TAC cranioencefálica sugere provável lesão de variante anatómica da artéria paramediana tálamosubtalâmica posterior. A propósito deste caso os autores fazem uma breve revisão desta forma de apresentação e das opções terapêuticas.

Angioplastia das Artérias do Sector Aorto-Ilíaco

Efectuou-se angioplastia transluminal percutânea (ATP) do sector aorto-ilíaco em 92 doentes, com lesões de aterosclerose. Conseguiu-se um sucesso inicial de 87,8% e um sucesso tardio de 69,4%. Os resultados tardios foram avaliados objectivamente em 58 doentes, 36 dos quais foram estudados por Angiografia e os restantes por Doppler. Houve complicações em 6,6% dos doentes das quais 2,8% eram graves tendo sido necessária intervenção cirúrgica. A mortalidade foi nula. Os bons resultados iniciais e tardios, a baixa morbilidade e a mortalidade nula levam-nos a concluir que a ATP é um bom método de revascularização altamente eficaz. Os melhores resultados obtiveram-se em doentes sintomáticos com estenose ou oclusão curta e significativa.
