Acute Mesenteric Venous Thrombosis.. in Assiut University Hospital Management Controversies

Not Applicable
Conditions
Mesenteric Vein Thrombosis

Procedure: MVT with failure of anticoagulation therapy
Registration Number
NCT03483207
Lead Sponsor
Assiut University
Brief Summary

Initial treatment in the management of acute mesenteric vein thrombosis (MVT) is controversial. Some authors have proposed a surgical approach, whereas others have advocated medical therapy (anticoagulation). In this study, the investigators analyzed and compared the results obtained with surgical and medical treatment to determine the best initial management for this disease.

Detailed Description

Mesenteric venous thrombosis (MVT) is increasingly recognized as a cause of mesenteric ischemia. it must be distinguished from arterial and non occlusive types of ischemia, it accounts for 5% to 15% of all cases of mesenteric ischemia. Patients may have evocative signs,such as abdominal pain that is out of proportion to physical signs, nausea, or vomiting. However, a clinical diagnosis is often difficult because abdominal symptoms are non specific and high index of suspicion is often required for diagnosis.(1) Primary MVT accounted for 25% to 55% of cases in early studies, but recent reports show decline in primary MVT because of improvements in the diagnosis of hypercoagulable states.(2) Advances in new imaging techniques also have enabled early recognition of this disease without or before laparotomy.(3-5 ) Fortunately , there is no consensus about the initial management of MVT; Some authors have proposed an aggressive surgical approach (6) while others have advocated an initial conservative management with anticoagulation and close monitoring . ( 7) similarly,issue of second look laparotomy,mandatory or selective is yet not resolved.

The present study is prompted to analyze our experience in an effort to resolve these controversies and the results obtained will be assessed to determine the best management strategy for this uncommon disease.

Primary Outcome Measures
NameTimeMethod
Anticoagulation therapy (heparin &warfarin) in MVOwithin 3-6 months of starting treatment.

patients with confirmed diagnosis of acute MVT on CT scan will be treated conservatively In addition to usual care such as fluid and electrolyte balance, antibiotic coverage and nasogastric intubation ,intravenous heparin will be started and the dose is adjusted to maintain APTT levels at 2-2.5 times the normal. followed by oral anticoagulation (warfarin) for 6 months or for life in the presence of coagulation abnormality. All patients will be critically followed up(Clinically.. Radiologically ) for the progress of response of therapy , failure to improve or worsening in condition( appearance of signs of peritonitis such as guarding, rigidity and fever...or radiological signs of bowel infarction) will be assessed .

Factors that may affect the response such as ( age, duration from onset of the disease till starting therapy,underlying diseases,.. )also complications (hemorrhage, failure ,..)will be assessed

Secondary Outcome Measures
NameTimeMethod
Recurrence ratewithin six months of starting treatment.

number of recurrent cases post conservative therapy .

Mortality ratewithin one year of starting treatment.

number of deaths as a complication of conservative therapy or surgery
