Prevalence of Vas Deferens Calcifications on Abdominal CT Examinations and Association With Systemic Conditions.

OBJECTIVE. The purpose of this study was to describe the prevalence of vas deferens (VD) calcifications on abdominal CT examinations and the associations between VD calcifications and several systemic conditions. MATERIALS AND METHODS. The CT examinations of male patients from January 2010 to December 2011 were retrospectively reviewed. After exclusions, the records of 1915 consecutively identified patients were analyzed. Five readers, 3rd- and 4th-year radiology residents, recorded the presence and laterality of VD calcifications and of vascular calcifications presumed due to atherosclerosis. A sixth reader parsed the patient records for diagnoses of type 2 diabetes mellitus (DM) and chronic kidney disease (CKD). RESULTS. The mean age of the entire sample population was 52.9 ± 18.9 years (range, 1-93 years). The mean age of patients with VD calcifications was 59.3 ± 12.0 (SD) years and of the group without VD calcifications was 52.9 ± 19.1 years (p = 0.17). The prevalence of VD calcification was 1.61% (31 patients): 21 (67.7%) of the patients had bilateral calcification; seven (22.6%), right-sided only; and three, (9.7%) left-sided. The frequency of DM was 28.8% (551/1915), of CKD was 7.58% (150/1915), and of atherosclerosis, 60.4% (1156/1915). The mean caliber of calcified VDs was 5.31 ± 1.29 mm versus 3.63 ± 0.63 mm for patients without calcification or any chronic condition (p < 0.0001). Among age, atherosclerosis, DM, and CKD in univariate regression analysis, only DM was associated with VD calcification (p = 0.006). However, because age (p = 0.063) and atherosclerosis (p = 0.057) were close to significant, they were included in the multivariate analysis, which also showed only DM associated with VD calcification (odds ratio, 2.14 ± 0.85). CONCLUSION. In the large cohort in this study, the prevalence of VD calcification was 1.61%. VD calcification was strongly associated with DM. The pathologic implications of VD calcification remain unclear and warrant further investigation in prospective longitudinal studies.

Revascularizaçäo do miocárdio: anastomose término-terminal: ponte intercoronariana: relato de 2 casos / Myocardial revascularization: termino-terminal anastomosis: intercoronarian anastomosis: report of 2 cases

Desde o início do tratamento cirúrgico da doença coronária obstrutiva com Vineberg até os dias atuais com o emprego de vários tipos de enxertos, os cirurgioes procuram aumentar a sobrevida bem como melhorar a qualidade de vida dos pacientes. Paciente de 60 anos de idade, com angina e síncope, cujo estudo hemodinâmico mostrou lesao de 90 por cento no ramo interventricular anterior (RIA) e 99 por cento na coronária direita (CD) (Figura 1). Foi revascularizado com artéria torácica interna esquerda (ATIE) para o RIA e ressecçao da lesao da CD, seguida de anastomose dos cotos (Figura 2). Paciente de 40 anos, com lesao de 80 por cento da CD e de 99 por cento do RIA foi igualmente revascularizado com enxerto livre de ATIE para o RIA e um segmento de 4 cm de ATIE em ponte coronária-coronária sobre o segmento lesado (Figura 3). Ambos os pacientes evoluíram bem na fase hospitalar. Após um ano, permanecem assintomáticos, com teste ergométrico negativo.
