BACKGROUND Lymphoscintigraphy has largely been performed to diagnose lymphedema. It is, however a time-consuming and expensive technique, which has not been covered by Japanese medical insurance since the year 2002. In this report we introduce a new imaging technique of fluorescent lymphography to diagnose lymphedema. METHODS Fluorescence images of(More)
Although inferior vena cava (IVC) filter placement has demonstrated an excellent therapeutic efficacy in preventing pulmonary embolism, several filter-related complications have been reported. Among them, retroperitoneal hemorrhage due to IVC perforation is one of the most serious complications. We report herein a female patient who underwent TrapEase IVC(More)
OBJECTIVES Lymph transportation through the body is partly controlled by the intrinsic pumping of lymphatic vessels. Although an understanding of this process is important for medical application, little is currently known because it is difficult to measure. Here, we introduce an easy, safe, and cost-effective technique for measuring lymphatic pumping in(More)
OBJECTIVES Venodynamics and lymphodynamics may interact as an inseparable and mutually dependent dual outflow system. This study investigated the effect of surgical treatment on lower limb lymph flow in patients with varicose veins. METHODS Thirty-nine patients with varicose veins in the lower limb (28 patients with unilateral limb, 11 patients with(More)
To assess the pelvic circulation during abdominal aortic aneurysm (AAA) repair by measuring the inferior mesenteric artery stump pressure (IMA-SP), penile blood flow, and gluteal blood flow. Twenty males were selected for this study. An aorto-bi-common iliac arteries (CIA) graft replacement was performed in ten patients (Group Bi-CIA). An(More)
BACKGROUND Resection of a gastrointestinal stromal tumor (GIST) of the rectum can be difficult because of the particular location in the pelvis, and a large rectal GIST often requires abdominoperineal resection. Recent reports demonstrate that neoadjuvant imatinib treatment improves surgical outcomes in patients with a rectal GIST, and there are only a few(More)
BACKGROUND Perfluorochemicals (PFC) are chemical substances that have a higher oxygen solubility under hyperbaric oxygen (HBO) pressure. This study investigated the effect of cold HBO-PFC/University of Wisconsin (UW) solution on preservation of rat small intestinal graft. METHODS We manufactured an air-tight, pressure-resistant tank made of stainless(More)
Surgical management of abdominal aortic aneurysm (AAA) with concomitant malignancy remains controversial. Commercial availability of a stentgraft may change the treatment strategy for such patients. We present a case of AAA with concomitant colon cancer, in which two-stage surgery consisting of EVAR and subsequent laparoscopic colectomy was performed with(More)
Gut barrier failure and the resultant translocation of luminal bacteria and bacterial products into the systemic circulation have been proposed as pathogenic mechanisms of multiorgan dysfunction syndrome (MODS) in open repair of abdominal aortic aneurysm (AAA). Our study aimed to demonstrate the direct release of gut-derived inflammatory mediators via the(More)
