Acute symptomatic mesenteric venous thrombosis: treatment by catheter-directed thrombolysis with transjugular intrahepatic route.
Summary of "Acute symptomatic mesenteric venous thrombosis: treatment by catheter-directed thrombolysis with transjugular intrahepatic route."
Objective: To assess the feasibility and effectiveness of transjugular intrahepatic route aspiration thrombectomy and catheter-directed thrombolytic therapy in patients with acute superior mesenteric venous thrombosis. Materials and methods: During a period of 8 years, 12 patients with acute thrombosis of the superior mesenteric vein (SMV) were treated by transjugular intrahepatic approach. The mean age was 41.2 years. After access to the portal system via the transjugular approach, the pigtail catheter fragmentation of the thrombus, local urokinase injection, and manual aspiration thrombectomy were used for treatment of the SMV thrombosis initially, followed by continuous thrombolytic therapy via an indwelling infusion catheter in the SMV, which was performed for 2 to 6 days (4.2 +/- 1.8 days). The adequacy of anticoagulation was performed during treatment, throughout hospitalization, and after discharge. Results: Technical success was achieved in all 12 patients. Substantial clinical improvement was seen in these patients after the procedure. Minor complications at the jugular puncture site were observed in 4 patients, but the thrombolytic therapy was not interrupted. Contrast-enhanced computed tomography (CT) scan before discharge demonstrated nearly complete disappearance of SMV thrombosis in all patients. The 12 patients were discharged 5-10 days (7.6 +/- 2.0) after admission. Mean duration of follow-up after hospital discharge was 37.7 months, and no recurrent episodes of SMV thrombosis developed during that time period. Conclusion: Catheter-directed thrombus aspiration, mechanical fragmentation, and local thrombolytic infusion via the transjugular intrahepatic route is a safe and effective therapy for the management of patients with acute symptomatic SMV thrombosis.

Medical and Biotech [MESH] Definitions
Protein S Deficiency
An autosomal dominant disorder showing decreased levels of plasma protein S antigen or activity, associated with venous thrombosis and pulmonary embolism. PROTEIN S is a vitamin K-dependent plasma protein that inhibits blood clotting by serving as a cofactor for activated PROTEIN C (also a vitamin K-dependent protein), and the clinical manifestations of its deficiency are virtually identical to those of protein C deficiency. Treatment with heparin for acute thrombotic processes is usually followed by maintenance administration of coumarin drugs for the prevention of recurrent thrombosis.

Intracranial Embolism And Thrombosis
Embolism or thrombosis involving blood vessels which supply intracranial structures. Emboli may originate from extracranial or intracranial sources. Thrombosis may occur in arterial or venous structures.
Sinus Thrombosis, Intracranial
Formation or presence of a blood clot (THROMBUS) in the CRANIAL SINUSES, large endothelium-lined venous channels situated within the SKULL. Intracranial sinuses, also called cranial venous sinuses, include the superior sagittal, cavernous, lateral, petrous sinuses, and many others. Cranial sinus thrombosis can lead to severe HEADACHE; SEIZURE; and other neurological defects.
Catheterization, Central Venous
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
Acute pancreatitis can result in many vascular complications in both artery and vein. Venous complication usually occurs as a form of splenic or portal vein thrombosis, and also can simultaneously occ...
