Objective To summarize recent clinical advances in intra-abdominal vascularized lymph node transfer (VLNT) for treatment of limb lymphedema. Methods A comprehensive review of the literature on intra-abdominal VLNT was conducted, outlining its historical development, relevant anatomy, and clinical applications, with emphasis on clinical outcomes. Results Intra-abdominal donor sites, such as the omentum and mesentery, are rich in lymphoid tissue and exhibit favorable anti-infective properties. Intra-abdominal VLNT has been widely applied in clinical practice internationally, while reports from China remain limited. Clinical studies indicate that intra-abdominal VLNT can effectively reduce limb swelling, lower infection rates, and improve quality of life in patients with limb lymphedema. It can also be combined with lymphaticovenular anastomosis, reductive procedures, and breast reconstruction to further alleviate symptoms and enhance patient-reported outcomes. Conclusion Intra-abdominal VLNT holds clinical application potential for the treatment of limb lymphedema, but more rigorous, standardized clinical studies are needed to further verify its feasibility and efficacy.
ObjectiveTo analyze the therapeutic effects of open surgery and endovascular treatment for mesenteric venous thrombosis.MethodsThe clinical data of 22 patients with mesenteric venous thrombosis from March 2005 to January 2014 were analyzed retrospectively. One patient underwent open surgery including removal of necrotic small intestine and thrombectomy of superior mesenteric vein immediately admission to the hospital. Five cases were treated with simple anticoagulation and cured. Sixteen cases received thrombolytic therapy after primary anticoagulant therapy.ResultsOne case who underwent open surgery died of multiple organ failure at 72 h after the surgery. Five cases who received simple anticoagulant reached clinical relief finally. Sixteen patients who received thrombolytic therapy achieved recanalization totally or partially. Three cases died during follow-up (3 months to 7 years, average) of which 1 died of recurrence of acute superior mesenteric venous thrombosis, 1 died of myocardial infarction, and 1 died of stroke.ConclusionsFor patients with symptomatic mesenteric venous thrombosis, if there is no intestinal necrosis, there will be encouraging results by interventional thrombolytic therapy. And the treatment effect needs further experience accumulation in more cases.
Objective To review the CT appearances and important differential diagnoses of various primary and secondary mesenteric neoplasms. Methods By describing the mesenteric anatiomy and major routes for the dissemination of metastatic mesenteric tumors, the article presents both the common and rare types of various primary and secondary mesenteric neoplasms, and addresses the characteristic CT appearances and important aspects of the differential diagnosis. Results CT study, especially the multislice spiral CT (MSCT), along with the clinical history and other related information, can nicely depict various mesenteric tumors and well differentiate them from infectious, inflammatory or vascular processes affecting the mesentery. Conclusion CT is the imaging method of choice for the evaluation of tumors of small bowel mesentery.
