ABSTRACT
Objective To evaluate the perioperative and long-term effects of endovascular aneurysm repair(EVAR) of infrarenal abdominal aortic aneurysm (AAA).Methods Clinical data of 131 AAA cases undergoing EVAR were retrospectively evaluated for the safety and long-term efficacy.Results The operative time was (137 ±29) min,blood loss was (142 ±20) ml,blood transfusion was (46 ± 26) ml,ICU staying time was (17 ± 4) h.Major perioperative complications were severe heart failure in 8 cases,myocardial infarction in 2 cases,pulmonary complications in 5 cases,internal leakage in 4 cases.During the period of up to 60 months there were15 cases of endoleak including 8 cases of type Ⅰ,5 cases of type Ⅱ,1 each case of type Ⅲ and Ⅳ and 2 deaths.By Kaplan-Meier survival analysis there were complications developing after 60 months and up to 40％ of them needing reintervention.Conclusions Endovascular repair is the safe treatment for AAA,but discharged patients need close long-term follow-up.Complications that ensued need intensive management.
ABSTRACT
ObjectiveTo investigate the clinical value of color Doppler ultrasound examination in the diagonosis of acute and chronic artery occlusion of the extremities.MethodsA review was made on 129 extremetiy artery occlusion patients at Anzhen Hospital during 2006 -2010. 85 cases were male, and 44 cases were female. Age was from 17 to 94 years (average: 62 ±9 years). We analyzed two-dimensional and color Doppler flow imagings of 39 acute occlusion arteries and 97 chronic occlusion arteries. We compared factors including the echoes of artery lumens, the vessel wall structures, hemodynamic parameters of inlet and outlet at the occlusion, and collaterals between groups.ResultsThe factors of depths of vessel wall,internal diameters of ccclusion arteries, proximal resistant index and collaterals were significantly different between groups ( P ＜ 0. 05 ). The internal diameters of acute occlusion arteries were wider than chronic occlusion arteries. The depths of vessel wall, proximal resistant index and collaterals were thinner, smaller,and less than chronic occlusion arteries. The total accurate rate of differential diagnosis for acute and chronic artery occlusion by color Doppler ultrasound was 95.6％.ConclusionsColor Doppler ultrasound is an effective method for the differential diagnosis of acute and chronic artery occlusion of the extremities.
