  • Analysis of Risk Factors for Acute Lower Deep Venous Thrombosis in Patients

    ObjectiveTo investigate the risk factors for lower limbs deep venous thrombosis(LDVT), and provide reference for the prevention and treatment of LDVT. MethodsThe pathogenic factors of 187 patients with LDVT in our hospital from 2010 to 2013 were retrospectively analyzed. ResultsOne hundred and eighty-seven patients with LDVT were 19-88 years old, mean 56.6 years old, and the age of onset was many in the 41-60 years old(65.2%). In 187 cases, male 102 cases, female 85 cases; left lower extremity in 112 cases, right lower extremity in 65 cases, and 10 cases of double lower limbs. LDVT predisposing factors were the lower extremities a history of fracture, surgery, tumor, bedridden, previous history of blood clots, and a small amount of internal diseases of unknown cause. ConclusionsLDVT occurs at 41-60 years old. The surgery, tumor, and history of thrombosis are independent risk factor of LDVT.

  • Improvement of Visceral Arterial Blood Supply after Thoracic Endovascular Aortic Repair for Stanford Type B Aortic Dissection

    ObjectiveTo investigate the improvement of visceral arterial blood supply after thoracic endovascular aortic repair (TEVAR) for patients with Stanford type B aortic dissection (AD). MethodsWe retrospectively analyzed clinical data of 35 patients with Stanford type B AD undergoing TEVAR in Mianyang Central Hospital from January 2013 to March 2014. There were 30 male and 5 female patients with their age of 45-82(62.5±10.0) years. Among the 140 main visceral arteries (celiac artery, superior mesenteric artery, left and right renal arteries) of the 35 patients, blood supply of 79 arteries were compromised, including 36 arteries with stenosis and blood supply via the true lumen, 18 arteries with blood supply via both true and false lumen, 18 arteries with blood supply via the false lumen, and 7 arteries without blood supply. Improvement of blood supply of main visceral arteries was analyzed. ResultsAll the operations were successfully performed without in-hospital death. Operation time was 97.8 (68-147) minutes, length of ICU stay was 12-34 h, and length of hospital stay was 10-21 days. None of the patients had cerebral infarction, acute renal failure, AD rupture or stent migration after TEVAR. Blood supply of the compromised visceral arteries showed improvement in various degrees. ConclusionFor the treatment of Stanford type B AD, TEVAR can not only successfully block the rupture of AD, but also improve blood supply of main visceral arteries, avoid or reduce the complications resulting from compromised visceral arterial blood supply and visceral ischemia.
