Isolated superior mesenteric artery dissection： case for conservative treatment and endovascular repair

引用

Chinese Medical Journal 2009年第2期122卷 238-240页

作者： WU Bin ZHANG Jian YIN Ming-di WANG Lei SONG Jin-qiu LI Xuan YANG Dong DUAN Zhi-quan XIN Shi-jie Department of Vascular Surgery First Hospital of China Medical University Shenyang Liaoning 110001 China

Dissection of the superior mesenteric artery （SMA） not associated aortic dissection is an uncommon event. The pathogenesis remains unclear. Diagnosis has become more efficient due to recent advances in imaging techniques and increased awareness of mesenteric vessel diseases. Early recognition has led to early interventions. Although there is still no consensus on the best option of management for this disease, an increasing number of patients in recent years have been reported to be treated successfully by non-operative approaches （medical therapy and/or percutaneous endovascular repair） rather than operations. We report the diagnosis and non-operative managements of isolated dissection of SMA in the acute stage in two cases at the First Hospital of China Medical University from October to December in 2006.

Flow-dependent regulation of vascular function and gene expression in rat superior mesenteric artery

引用

Chinese Medical Journal 2009年第10期122卷 1195-1198页

作者： XIA Shang DENG Chang-sheng Department of Gastroenterology Zhongnan Hospital of Wuhan University Wuhan Hubei 430071 China

Background mesenteric artery thrombosis is prone to occur at specific arterial regions with different fluid flow patterns, yet mechanistic links between blood flow and vascular function remain unclear. This study aimd to investigate the role of blood flow in regulation of vascular function and gene expression in rats. Methods isometric tension was recorded in wire myograph to examine vascular function of specific regions （trunk parts and proximal parts from the origin） with different blood flow in superior mesenterJc artery （SMA）. Endothelial nitric oxide syntheses （eNOS）, phosphorylated-eNOS （p-eNOS）, serine-threonine kinase Akt and phosphorylated-Akt （p-Akt） protein expressions in SMA were examined by Western blotting. Significance was analyzed using a Student＇s t test or analysis of variance （ANOVA） followed by a Dunnett＇s multiple-comparison post hoc test. Results Compared with trunks, proximal parts exhibited severely impaired relaxant responses to acetylcholine （Ach）（1 nmol/L to 10 μmol/L）（P 〈0.01）. p-eNOS and p-Akt protein levels were significantly reduced in proximal parts of SMA （0.37±0.03, 0.42±0.03 respectively） versus trunk parts （0.82±0.03, 0.72±0.03 respectively, both P 〈0.05） while total eNOS and Akt expressions remain comparable in both regions by Western blotting analysis （0.70±0.03 vs 0.82±0.03; 0.70±0.03 vs 0.77±0.03 respectively, both P 〉0.05）. Conclusion Critical components that drive the vascular function and influence the localization of mesenteric artery thrombosis are flow-responsive elements within the vascular endothelium.

Pseudoaneurysm of gastroduodenal artery following radical gastrectomy for gastric carcinoma patients

引用

World Journal of Gastroenterology 2003年第12期9卷 2878-2879页

作者： Dong YiKim Jae KyoonJoo SeongYeobRyu Young JinKim Shin KonKim Yong-Yeon Jung Division of Gatroenterologic Surgery Department of SurgeryChonnam National University Medical SchoolGwangjuKorea Department of Radiology Chonnam National University Medical SchoolGwangjuKorea

We report a rare case of postoperative pseudoaneurysm of the gastroduodenal artery following radical *** trauma to the gastroduodenal artery during regional lymphadenectomy was considered as the cause of the postoperative pseudoaneurysm. The pseudoaneurysm was successfully managed by ligating the bleeding vessel. We should consider the possibility of pseudoaneurysm formation in a patient with gastrointestinal bleeding in the postoperative period following radical gastrectomy with regional lymph node and perivascular lymphatic dissection.
