Mesenteric venous thrombosis: A changing clinical entity
Journal of Vascular Surgery, 2001
Objective: Mesenteric venous thrombosis (MVT) and its clinical spectrum have become better defined following improvements in diagnostic imaging. Historically, MVT has been described as a morbid clinical entity, but this may not necessarily be true. Often, an underlying disease process that predisposes a patient to MVT can be found and potentially treated. This study was designed to evaluate the diagnostics and management of MVT and to review long-term results of treatment. Patients: Thirty-one patients in whom MVT was diagnosed between 1985 and 1999 were retrospectively reviewed. Survivors were contacted for follow-up. There were 15 men and 16 women. Ages ranged from 22 to 80 years (mean, 49.1 years). Thirteen patients had documented hypercoagulability, 10 had a history of previous abdominal surgery, 6 had a prior thrombotic episode, and 4 had a history of cancer. MVT presented as abdominal pain (84%), diarrhea (42%), and nausea/vomiting (32%). Computed tomography (CT) was considered diagnostic in 18 (90%) of 20 patients who underwent the test. CT diagnosed MVT in 15 (100%) of 15 patients presenting with vague abdominal pain or diarrhea. Angiography demonstrated MVT in only five (55.5%) of nine patients. Results: Seven of 31 patients died within 30 days (< 30-day mortality rate, 23%). Twenty-two patients (72%) were initially treated with heparin. Nine patients were not heparinized: four of them died, and two were later given warfarin sodium (Coumadin). Of the 31 patients, only one received lytic therapy. Three patients became symptom free without anticoagulation. Ten patients (32%) underwent bowel resection. Overall, 19 (79%) of 24 survivors were treated with long-term warfarin therapy. Long-term follow-up was obtained in 24 patients (mean, 57.7 months). Twenty-one (88%) of 24 survived in follow-up. Conclusion: The diagnosis of MVT should be suspected when acute abdominal symptoms develop in patients with prior thrombotic episodes or a documented coagulopathy. CT scanning appears to be the primary diagnostic test of choice. Anticoagulation is recommended. If diagnosed and treated early, MVT is not likely to progress to gangrenous bowel. Recent mortality rates for MVT are lower than previously published, perhaps because of earlier diagnosis and aggressive treatment or possibly because we now readily diagnose a more benign form of the disease, which is due to widespread use of CT scanning.
Mesenteric venous thrombosis with transmural intestinal infarction: A population-based study
Journal of Vascular Surgery, 2005
To determine the cause-specific mortality from and incidence of transmural intestinal infarction caused by mesenteric venous thrombosis (MVT) in a population-based study and to evaluate the findings at autopsy by evaluating autopsies and surgical procedures. Methods: All clinical (n ؍ 23,446) and forensic (n ؍ 7569) autopsies performed in the city of Malmö between 1970 and 1982 (population 264,000 to 230,000) were evaluated. The autopsy rate was 87%. The surgical procedures were performed in 1970, 1976, and 1982. Autopsy protocols coded for intestinal ischemia or mesenteric vessel occlusion, or both, were identified in a database. In all, 997 of 23,446 clinical and 9 of 7,569 forensic autopsy protocols were analyzed. A 3-year sample of the surgical procedures, comprising 21.3% (11,985 of 56,251) of all operations performed during the entire study period, was chosen to capture trends of diagnostic and surgical activity. In a nested case-control study within the clinical autopsy cohort, four MVT-free controls, matched for gender, age at death, and year of death were identified for each fatal MVT case to evaluate the clinical autopsy findings. Results: Four forensic and 23 clinical autopsies demonstrated MVT with intestinal infarction. Seven patients were operated on, of whom six survived. The cause-specific mortality ratio was 0.9:1000 autopsies. The incidence was 1.8/100,000 person years. At autopsy, portal vein thrombosis and systemic venous thromboembolism occurred in 2 of 3 and 1 of 2 of the cases, respectively. Obesity was an independent risk factor for fatal MVT (P .)120.؍ Conclusions: The estimated incidence of MVT with transmural intestinal infarction was 1.8/100,000 person years. Portal vein thrombosis, systemic venous thromboembolism and obesity were associated with fatal MVT. ( J Vasc Surg 2005;41: 59-63.)
A study of 25 patients on surgical management of acute mesenteric vascular thrombosis
International Journal of Surgery Science, 2021
To study outcome of surgical management of acute mesenteric vascular thrombosis like Extent of disease Extent of resection Post-operative survival Patients and Methods: This study of 25 cases of diagnosed with acute mesenteric vascular thrombosis (MVT) from September 2016 to October 2018 in department of surgery, civil hospital Ahmadabad. Inclusion criteria: Patients with acute abdominal pain who is diagnosed as MVT in either on CT-scan or on exploration. Exclusion criteria: Patient with non-occlusive mesenteric ischemia that did not require laparotomy. Patient with only portal vein thrombosis. Results: Among 25 patients, 23 patients underwent exploratory laparotomy. Two patients were expired before surgery. In present study, maximum number of patients is in the age group 41-50 years. In 23 patients exploratory laparotomy was done based on their clinical feature with peritoneal signs with CECTabdomen pelvis finding. Mortality rate was 64% in my study while 9 (36%) patients are in follow-up, so early diagnosis and decision of intervention has saved 36% of patients. Conclusion: Mesenteric vascular thrombosis is one of the most lethal vascular disorders. So, this type of moribund conditions require urgent use of abdominal CT-Scan and increasing use of anti-coagulative medication improved the outcome in patients. This disease entity is lethal prompt decisions should be taken for patients survival.
Management Of Bowel Ischemia Secondary To Mesenteric Vein Thrombosis: A Tight Rope Walk
The Internet Journal of Gastroenterology, 2010
Acute superior mesenteric vein (SMV) and portal vein (PV) thrombosis can be a complication of hypercoagulable, inflammatory, or infectious states. It can also occur as a complication of medical or surgical intervention. Management of mesenteric and portal vein thrombosis includes both operative and non-operative approaches. Operative interventions include thrombectomy with thrombolysis; this is often employed for patients who present with signs of peritoneal irritation. Nonoperative approaches can be either noninvasive or invasive. Treatment with anticoagulation has been shown to be efficacious, though its rate of recanalization is not as high as with intravascular infusion of thrombolytics. We here describe an interesting case report of a patient who developed ischemic bowel secondary to mesenteric vein thrombosis, who did not qualify for a surgical emergency and provided an interesting challenge in medical management until surgery finally took over the specific management.
Open Thrombectomy for Primary Acute Mesenterico-portal Venous Thrombosis – Should It Be Done?
Annals of Vascular Surgery, 2015
Mesentericoportal venous thrombosis (MVT) is a rare condition, accounting for 5e15% of acute mesenteric ischemia. Primary MVT is even rarer, with some reports quoting an incidence rate of 10e30% of reported cases. It presents a diagnostic challenge and is associated with a significant mortality rate, ranging from 13% to 50%. As it is an uncommon condition, the evidence in current literature regarding the treatment of MVT is limited. We discuss our surgical experience with a case of acute primary MVT that was managed with good clinical outcome and discuss the current evidence for the treatment of acute MVT. A 50-year-old Chinese lady with no significant past medical history presented with a 2-day history of abdominal pain and epigastric tenderness on examination. Computed tomography of her abdomen and pelvis showed evidence of extensive acute thrombi present in portal confluence extending into the superior mesenteric vein, associated with submucosal edema in some central jejunal loops. Despite systemic anticoagulation therapy with intravenous heparin, the patient deteriorated clinically, and decision was made for an exploratory laparotomy, small bowel resection, and open thrombectomy. Postoperative recovery was uneventful. She was discharged on postoperative day 13 with lifelong oral anticoagulation. In conclusion, we describe the successful management of a patient with extensive acute primary MVT where open thrombectomy was performed together with small bowel resection.
The Management of Mesenteric Vein Thrombosis: A Single Institution Experience
Turkish Journal of Trauma and Emergency Surgery, 2013
Mesenteric vein thrombosis occurs rarely and is responsible for approximately 5-15% of all cases of acute mesenteric ischemia. The aim of this report was to discuss the management of mesenteric vein thrombosis based on our experience with 34 patients. METHODS In the present study, 34 patients who were admitted to our emergency surgery department between January 2007 and January 2010 with a diagnosis of acute mesenteric vein thrombosis were assessed retrospectively. Patients with peritoneal signs first underwent diagnostic laparoscopy to rule out perforation or bowel gangrene. We performed a second-look laparoscopy within 72 hours of the first operation. All patients were administered 100 mg/kg of the anticoagulant enoxaparin twice daily. In the 6th and 12th months of follow up, CT angiography was performed to evaluate recanalization of the veins. RESULTS CT angiography revealed superior mesenteric vein thrombosis in 25 (73%) patients, portal vein thrombosis in 24 (70%) patients, and splenic vein thrombosis in 12 (35%) patients. Eleven patients with peritoneal signs underwent diagnostic laparoscopy; eight of the patients underwent small bowel resection, anastomosis, and trocar insertion. During second-look laparoscopy, small bowel ischemia was found in two patients and re-resection was performed. CONCLUSION Early diagnosis with CT angiography, surgical and nonsurgical blood flow restoration, proper anticoagulation, and supportive intensive care are the cornerstones of successful treatment of mesenteric vein thrombosis.
Superior mesenteric venous thrombosis presenting with hematemesis: a case report
The Annals of African Surgery, 2022
The superior mesenteric vein (SMV) is one of the two tributaries to the portal vein, which is the main prehepatic drainage channel of the splanchnic circulation. Venous thrombosis in the SMV is one of the rare causes of splanchnic ischemic syndrome. Clinical presentation is often vague abdominal symptoms. It seldom presents with hematemesis, which may further confound diagnosis, thereby increasing the risk of poor outcomes. This case highlights an otherwise healthy 31-year-old woman, who presenting at a tertiary hospital in Nairobi with a 2-day history of epigastric pain and copious hematemesis. She had been treated for Helicobacter pylori gastritis 2 months prior. Common differentials were considered. However, with normal esophagogastroduodenoscopy findings and darkcolored fluid sequestered in the upper gastrointestinal tract, mesenteric venous congestion with associated small bowel ischemia was suspected. Three-phase abdominal computed tomography angiogram confirmed proximal superior mesenteric venous thrombosis extending into the portal vein confluence. Associated small bowel necrosis was suspected, and surgery involving resection and primary ileo-jejunal anastomosis was performed. Post-operative 2-week parenteral nutrition and anticoagulation were administered. The patient was discharged after 3 weeks of hospitalization and remains in excellent condition.
International Journal of Surgery Case Reports
To present two cases of acute non-cirrhotic and non-malignant mesenteric vein thrombosis (MVT) treated with early transcatheter thrombectomy and thrombolysis with tissue plasminogen activator (tPA) and to review the literature on transcatheter thrombectomy and thrombolytic therapy of such condition. METHODS: Two cases of acute MVT treated with transhepatic transcatheter thrombectomy and thrombolysis in addition to systemic anticoagulation upon diagnosis are presented. In addition, a Pubmed literature search was undertaken using keywords acute mesenteric vein thrombosis, thrombolysis and thrombectomy. The inclusion criteria were studies examining the impacts of transcatheter thrombolysis and thrombectomy in the management of acute MVT. RESULTS: Early transcatheter thrombectomy and thrombolysis achieves technical success in both patients and result in nearly complete recanalization of the venous system, with no recurrent thrombosis to date in follow up. Both patients do not require extensive bowel resection despite extensive thrombus on presentation. However, both patients develop intra-abdominal bleeding requiring blood transfusion and embolization of the transcatheter tract. CONCLUSION: Catheter-directed first approach provides a minimal invasive approach for management of non-malignant and non-cirrhotic acute mesenteric thrombosis. It offers the benefits of rapid venous recanalization and avoid massing bowel resection despite extensive thrombosis. Subsequent progression into chronic MVT was also reduced. However, the procedure could lead to bleeding from puncture site and hence embolization of the catheter tract is advised during catheter removal.
