The present study was undertaken to establish the role of NADPH oxidase (Nox) in impaired vascular compensation to arterial occlusion that occurs in the presence of risk factors associated with oxidative stress. Diet-induced obese (DIO) mice characterized by multiple comorbidities including diabetes and hyperlipidemia were used as a preclinical model. Arterial occlusion was induced by distal fe...

Consensus does not exist on the level of arterial ligation in rectal cancer surgery. From oncologic considerations, many surgeons apply high tie arterial ligation (level of inferior mesenteric artery). Other strategies include ligation at the level of the superior rectal artery, just caudally to the origin of the left colic artery (low tie), and ligation at a level without any intraoperative de...

This study was performed to examine, first, the protective effects and responses of collateral vessels of the hind limb in normal and atherosclerotic monkeys and, second, the effects of chronic arterial occlusion on the development of atherosclerosis. The iliac artery was ligated on one side in cynomolgus monkeys. Sixteen months later, we recorded the pressure gradient across the limb collatera...

We have previously shown that intrasplenic fluid extravasation is important in controlling blood volume. We proposed that, because the splenic vein flows in the portal vein, portal hypertension would increase splenic venous pressure and thus increase intrasplenic microvascular pressure and fluid extravasation. Given that the rat spleen has no capacity to store/release blood, intrasplenic fluid ...

Ligation of a patent arterial duct in a 7 year old girl with intractable heart failure in 1938 was the first successful “cardiac” operation and may therefore be considered the forerunner of the remarkable developments in surgery for both congenital and acquired heart disease which have occurred since then. It was soon established that ligation of a large arterial duct could not only resolve hea...

Puerperal hematoma is one of the life threatening obstetrical emergencies. Surgical ligation of bleeding vessel may not always be possible for the patients who were hemodynamically unstable, hence pelvic arterial angiography may be preferred as the first line treatment modality for these cases. Pelvic arterial angiography and embolization is a safe, tolerable, and minimally invasive treatment m...

Penetrating cerebrovascular injuries (PCVI) are associated with a high incidence of mortality and neurologic events. The optimal treatment strategy PCVI, especially when damage control measures required, remains controversial. aim this study is to describe the management PCVI patient outcomes at level 1 trauma center where vascular predominantly managed by surgeons. An institutional registry wa...

24 This study was undertaken to establish the role of NADPH oxidase (Nox) in impaired vascular 25 compensation to arterial occlusion that occurs in the presence of risk factors associated with 26 oxidative stress. Diet-induced obese (DIO) mice characterized by multiple comorbidities 27 including diabetes and hyperlipidemia were utilized as a preclinical model. Arterial occlusion 28 was induced ...
