Abstract:
Objective To explore the surgical effects and follow-up results in treating adult aortic coarctation patients using ascending aorta-abdominal aorta vascular prosthesis bypass and summarize the clinical experiences. Methods From May 2008 to July 2009, ascending aorta-abdominal aorta vascular prosthesis bypass surgery was performed in nine patients with adult aortic coarctation, among which, four were male, and five were female, with the average age of 42.6 years old. All patients had upper extremity hypertension, the systolic blood pressure difference between their upper extremities and lower extremities was 55 - 100 mm Hg, mean (70.2 ± 15. 6) mm Hg. Among which, seven cases showed descending aorta aneurysmal dilatation at coarctation segment distal end, with the wall thinning; two cases showed long segment stenosis; three cases showed aortic wall near coarctation segment was calcified. All cases belonged to complex aortic coarctation. All patients underwent radial artery and dorsalis pedis artery puncture manometry, the surgical effects were evaluated according to mean pressure difference changes between radial artery and dorsalis pedis artery before and after operations. Results All patients were cured and dispertension has been significantly improved, before operation, the mean pressure difference between radial artery and dorsalis pedis artery was 36 - 63 mm Hg, mean [(48.2 ± 5.6 ) mm Hg]; 24 hours after operation, the mean pressure difference between radial artery and dorsalis pedis artery was 0 - 13 mm Hg, mean [(6.2 ± 1.6) mm Hg], significantly reduced ( P ＜per extremity hypertension disappeared, no need for oral antihypertensive drugs, the mean pressure differences between upper extremities and lower extremities after operations were all less than 20 mm Hg, thoracoabodominal aorta main vessels multi-slice CT examination three months after operation showed that bypass vascular prosthesis was unobetructed, two cases showed that autologous artery at aortic coarctation distal end were partly occluded. Conclusion Ascending aorta-abdominal aorta vascular prosthesis bypass would be an effective means for the treatment of adult aortic coarctation patients.
