RESUMEN
Objective To investigate the clinical values of quantitative ultrasound elastography technique in detecting internal carotid artery thickness .Methods One hundred and forty healthy objects who have conducted physical examination in our hospital from February 2012 to August 2015 were selected ,and divided in to three groups:the healthy control group (n=40;IMT<0 .9 mm) ,the IMT thickening group (n=60;0 .9 mm≤ IMT < 1 .3 mm) and plaque group(n= 40 ;IMT ≥1 .3 mm) .All the three groups conducted routine ultrasound and quantitative ultrasound elastography ,and the clinical data investigation and laboratory ex‐amination were carried out at the same time .Results The TC ,LDL‐C values in the plaque group and intimal thickening group were significantly higher than the control group (P<0 .05) .The AC values in the plaque group and intimal thickening group were signif‐icantly higher than the control group (P<0 .05) ,while the AI and PWVβvalues were significantly lower(P<0 .05) .Linear corre‐lation analysis showed that IMT were positively correlated to the AI ,PWVβ (r=0 .512 ,P <0 .05 ;r= 0 .483 ,P<0 .05) ,and the AC were negatively correlated (r= -0 .713 ,P<0 .05);Logistic analysis showed that LDL‐C ,AC ,PWVβwere the major independ‐ent risk factors for IM T (P<0 .05) .Conclusion Ultrasound elasticity quantitative detection of neck vessels is safe and can non‐in‐vasive dynamically observe blood vessel wall changes during the progression of atherosclerosis ,thus it's helpful in the judge and i‐dentification of internal carotid artery thickness .
RESUMEN
Four cases medical accidents related to the iatrogenic injury of neck vessels are reported. The first case was a 54-year-old woman. Under the diagnosis of the herniated cervical disc, the operation was performed. After five hours from starting the operation, respiratory difficulty, facial cyanosis and syncope were found, suddenly. The autopsy finding were large hematoma at the posterior portion of neck organ and perforation of right carotid artery. The second case was a 61-year-old woman. Under the diagnosis of the aneurysm of the anterior communicating artery, the coiling and embolization were performed. After one hour from removal of catheter of right carotid artery, respiratory difficulty, facial cyanosis and syncope associated with right neck hematoma were found, suddenly. Eventually, she died after 41 days due to hypoxic brain injury. The third case was a 55-year-old woman. Under the diagnosis of the thyroid cancer, total thyroidectomy was performed. After three hours from operation, respiratory difficulty, facial cyanosis and syncope associated with severe neck hematoma were found, suddenly. Eventually, she died after 25 days due to hypoxic brain injury. The last case was a 34-year-old man. He visited the hospital due to stab wound of left neck. The irrigation and simple suture were performed at the first visit. After he went home, respiratory difficulty and syncope were found, suddenly. He returned the hospital and cardiopulmonary resuscitation was performed. However, he died. The autopsy finding were large hematoma around the neck organ and stab wound of left carotid artery.
