Clinical complications in patients with severe cervical spinal trauma: a ten-year prospective study / Complicações clínicas em pacientes com trauma raquimedular cervical grave: estudo prospectivo de dez anos

OBJECTIVE: To determine the complications due to severe acrescentar sigla após o nome (CST). METHODS: Between 1997 and 2006, 217 patients (191 men and 26 women) were prospectively evaluated. The mean age was 36.75±1.06 years. RESULTS: Forty-five percent of the patients had medical complications. The most important risk factor was alcoholic beverage use. The most important associated injury was head trauma (HT). Patients with American Spine Injury Association (ASIA) A or B had a 2.3-fold greater relative risk of developing complications. Thirty-three patients (15.2%) died. Patients with neurological deficit had a 16.9-fold higher risk of death. There was no influence of age and time between trauma and surgery on the presence of complications. CONCLUSIONS: Of the patients, 45% had clinical complications and 7.5% had associated injuries; pneumonia was the most important complication; patient age and time between trauma and surgery did not influence the development of medical complications; neurological status was the most important factor in determining morbidity and mortality.

OBJETIVO: Identificar complicações decorrentes do trauma raquimedular cervical grave. MÉTODOS: Avaliação prospectiva de 217 pacientes (191 homens e 26 mulheres) entre 1997 e 2006, com média de idade de 36,75±1,06 anos. RESULTADOS: Houve complicações em 45% dos pacientes. O fator de risco mais importante foi ingestão de bebida alcoólica. Trauma craniano foi a associação mais frequente. Pacientes com classificação A ou B da American Spine Injury Association (ASIA) tiveram 2,3 vezes maior chance de complicações. Faleceram 33 pacientes (15,2%), sendo a chance de óbito 16,9 vezes maior naqueles com déficit neurológico. Não houve influência da idade ou do tempo decorrido entre o trauma e a cirurgia. CONCLUSÕES: Dos pacientes, 45% apresentaram complicações e 7,5% apresentaram traumas associados; pneumonia foi a principal complicação clínica; a idade dos pacientes e o tempo entre o trauma e a cirurgia não influenciaram na frequência de complicações; o status neurológico após o trauma foi o fator de risco mais importante na determinação de morbidade e mortalidade.

Anatomical study of the anterior interventricular septal branches and their relationship with the blood supply of the septomarginal trabecula

The aim of this study was to examine the morphological features of the anterior interventricular septal branches that supply blood to the septomarginal trabecula and to correlate the anatomical observations with the angiographic characteristics analyzed by hemodynamic procedures. Forty human hearts were dissected after injecting colored latex into the left coronary artery. The vascularization of the septomarginal trabecula was always derived from the anterior interventricular artery, via the first, second and third anterior interventricular septal branches in 21 hearts (52.5%), 17 hearts (42.5%) and two hearts (5%), respectively, and the distances from the left coronary artery ostium ranged from 22 to 51 mm. The external diameter of these vessels at their origin varied from 1.0 to 2.35 mm and the vessels were analyzed based on specific requirements for surgical and hemodynamic methods of myocardial revascularization. Myocardial bridges were located over or before the origin of the vessels studied.
