Rationale:Acute mesenteric vein thrombosis (MVT) is defined as new-onset thrombosis of the mesenteric vein without evidence of collateralization, finally resulting in extensive intestinal infarction. MVT may be idiopathic or be caused by conditions responsible for thrombophilia and acquired risk factors. To date, there have been few reports of MVT after trauma. Herein we describe our experiences treating three patients with MVT.Patient concerns:Case 1 was a 44-year-old man with transverse colon mesenteric hematoma after blunt abdominal trauma. Case 2 was a 55-year-old man with jejunal transection after a traffic accident. Case 3 was a 26-year-old man presented with multiple abdominal stab bowel injury.Diagnoses:A 1-week follow-up abdominal computed tomography scan showed superior mesenteric vein thrombosis in all of three patients.Interventions:All patients were treated with anticoagulant for 3 or 6 months.Outcomes:MVTs were completely resolved without any complications.Lessons:If early diagnosis and treatment could be available, anticoagulation alone might be adequate for the treatment of SMVT associated with trauma. Early anticoagulation in patients with acute SMVT may avoid the grave prognosis observed in patients with arterial thrombosis.
Purpose:Our study aims to evaluate to evaluate clinical outcomes after cephalic vein transposition (CVT) to the axilla in patients with brachiocephalic arteriovenous fistula (BC-AVF) and cephalic arch stenosis (CAS).Materials and Methods:Hospital records of 13 patients (median age, 61 years; males, 54%) who received CVT to the proximal basilic/axillary vein due to either dysfunction (n=2) or thrombosis (n=11) between January 2010 and February 2014 were retrospectively reviewed.Results:Operation was performed under local anesthesia in all cases. There was no technical failure. Concomitant inflow procedure (banding or aneurysmorrhaphy) was performed in 5 patients (38%). During follow-up (1 to 50 months, median 17 months), 3 patients died with functioning AVF and one was successfully transplanted. Two patients suffered from recurrent symptomatic stenosis of AVF and received percutaneous balloon angioplasty. Another 2 patients experienced AVF occlusion treated with interposition graft and manual fragmentation. Overall primary, assisted primary, and secondary patency rates were 77.5%, 92.3%, and 100% at 6 months and 66.1%, 92.3%, and 100% at 1 year, respectively.Conclusion:Although most patients presented with BC-AVF occlusion, technical success and access patency rates after CVT were favorable compared with historical data for interventional treatment. CVT should be considered as an appropriate option in selected patients with CAS.
PurposeTo determine the efficacy of a retrievable inferior vena cava filter (IVCF) for patients with deep vein thrombosis (DVT) and transient contraindication for anticoagulant therapy, and to analyze the risk factors for filter thrombus in these patients.MethodsWe retrospectively reviewed the records of 70 patients who received a retrievable IVCF from January 2007 to June 2014 because of documented DVT and transient contraindication for anticoagulant therapy. The protocol for follow-up care generally consisted of anticoagulant therapy after high-risk periods, follow-up CT around 2 weeks after IVCF placement, and retrieval if possible.ResultsThe 70 patients had a mean age of 61.8 years (range, 17-88 years), and 30 were male (43%). The indications for IVCF were recent trauma including surgery in 48 patients, recent hemorrhage in 14, and planned major surgery with DVT in 8 patients. Follow-up CT of 61 patients (87%) was performed. Aggravation or new development of pulmonary embolism (PE) was not found in any patient. Filter thrombus was detected in 23% of patients with follow-up CT (14/61). Filter thrombus was not detected in patients with isolated calf vein thrombosis (ICVT) (P = 0.079). The risk factor for filter thrombus was DVT progression on follow-up CT (P = 0.007) on multivariate analysis.ConclusionFor patients with DVT and transient contraindication for anticoagulant therapy, a retrievable IVCF could prevent the aggravation or new development of PE. DVT progression on follow-up CT was associated with filter thrombus and ICVT was not related to filter thrombus in the present study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
