Spontaneous Resolution of Portal Vein Thrombosis (original) (raw)

Portal Vein Thrombosis in Non Cirrhotic Patients: Experience of Gastroenterology and Hepatology Department University Hospital Hassan II

Open Journal of Gastroenterology, 2020

Portal thrombosis (PT) is a rare condition of heterogeneous etiologies. The aim of our work is to study the epidemiological and etiological profile of portal thrombosis in non cirrhotic patients through the experience of our department. Patients and Methods: This is a retrospective study over a 9-year period (January 2009-July 2018), 54 cases of PT in non cirrhotic patients were collected in the department of Hepato-Gastro-Enterology of the HASSAN II Fez Hospital, 73 cases of PT were excluded among cirrhotic patients. Results: We collected 54 cases of PT cases; the average age was 45 years, with an F/M ratio of 1.42. PT was revealed by abdominal pain in 20 cases, complications of portal hypertension in 24 cases, and ultrasound discovery in 10 asymptomatic cases. Main underlying causes of PT were: A proteine S deficiency in 7 cases, Acute pancreatitis in 5 cases, colonic cancer in 4 cases, pancreatic cancer in 4 cases, Hydatic liver Echinococcoses (3 cases), anti phospholipid syndrom (3 cases), myeloproliferative syndrom (2 cases) and jak mutation 2 in 1 case, non identified etiology was reported in 20 cases (37%). Treatment was based on anticoagulation, treatment of portal hypertension complications, and etiological treatment in cases where etiological diagnosis was certainly posed. Conclusion: PT is a rare but serious condition, according to our study neoplastic causes are predominant followed by protein S deficiency. Etiological investigations have to be wide and early treatment is the best option to avoid extension and complication.

Portal Vein Thrombosis: A Case report and Literature Review

A case report of Portal Vein Thrombosis (PVT) as a complication of protein S deficiency. PVT has been increasingly diagnosed over the years, particularly through the use of ultrasound-Doppler equipment. The lifetime risk of getting PVT in the general population has recently reported to be 1%.1 While this condition has traditionally been associated with cirrhosis or liver malignancy, it may also occur without any liver disease. The case report is followed by a discussion of the aetiology and clinical presentations of PVT, as well as a review of the investigations and management proposed in the literature.

Portal vein thrombosis: Insight into physiopathology, diagnosis, and treatment

World Journal of Gastroenterology, 2010

Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but might also occur in absence of an overt liver disease. Several causes, either local or systemic, might play an important role in PVT pathogenesis. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernable. Clinical examination, laboratory investigations, and imaging are helpful to provide a quick diagnosis, as prompt treatment might greatly affect a patient's outcome. In this review, we analyze the physiopathological mechanisms of PVT development, together with the hemodynamic and functional alterations related to this condition. Moreover, we describe the principal factors most frequently involved in PVT development and the recent knowledge concerning diagnostic and therapeutic procedures. Finally, we analyze the implications of PVT in the setting of liver transplantation and its possible influence on patients' future prognoses.

POST-GRADUATE CLINIC Portal Vein Thrombosis – Clinical Profile

Portal vein thrombosis is commonly forgotten as a possible cause of abdominal pain, portal systemic encephalopathy, or gastrointestinal haemorrhage caused by oesophageal varices, splenomegaly, and/or ascites. It can complicate the underlying pathology and can increase morbidity and mortality. There can be varied aetiology and pathogenesis of portal vein thrombosis. Usually, the radiologic diagnosis is made either by duplex Doppler ultrasonography and/or colour Doppler ultrasonography. CT scan, magnetic resonance angiography (MRA) and arterial portography or splenoportography. MRI seems a very promising method. The treatment, course, and the prognosis of portal vein thrombosis depends on the aetiology of the disease. Here we are presenting three cases of portal vein thrombosis with different aetiology.

Portal Thrombosis: Clinical, Etiological and Therapeutic Aspects in the Hepato-Gastroenterology Department of the Aristide Le Dantec Hospital in Dakar (Senegal)

Open Journal of Gastroenterology, 2021

Background: Portal thrombosis (PT) is a rare pathology. Its prevalence is estimated at 1%. Its consequences depend on the acute or chronic nature, the extent of the clot and the etiology. In Sub-Saharan Africa, very few studies have been devoted to it. Patients and Method: The objective of our work was to determine the prevalence of PT and to describe its clinical and etiological presentation as well as its therapeutic management in the Hepato-gastroenterology department of the Aristide Le Dantec hospital in Dakar. This was a retrospective, longitudinal and descriptive study during the period from January 1, 2012, to December 31, 2018. It included all patients followed in ambulatory or inpatient, who presented a PT objectively determined by a medical imaging examination (ultrasound and/or CT scan). Age, gender, clinical and radiological aspects, proposed treatments and etiology of PT were collected. Results: We collected 71 observations. The prevalence of PT was 1.9%. The mean age of the patients was 41 years 15 and 75 years. A predominance of men was found with a sex ratio of 2.73. The clinical manifestations were dominated by abdominal pain (74.6%), ascites (35.7%) and gastrointestinal bleeding (25.4%). Imaging allowed the diagnosis to be made in 50 patients on ultrasound and 21 patients on abdominal CT scan. PT was acute in 5 patients and chronic in 66 patients. Thrombosis was complete in 71.4% of cases and extended to the spleno-mesaraic venous trunk and the superior mesenteric vein in 2.8% and 8.4% respectively. Etiological research found cirrhosis complicated by hepatocellular carcinoma in 67.6% of cases, cirrhosis with cruoric

Portal vein thrombosis: A concise review (Review)

Experimental and Therapeutic Medicine, 2021

Portal vein thrombosis (PVT) is a frequent complication in cirrhotic patients, but it may also exist as a basic vascular condition even without any liver damage. Local and systemic factors play a significant role in the pathogenesis of PVT; yet, in practice, more than one factor may be identified. PVT can be considered a result of liver fibrosis and hepatic insufficiency. The JAK2 mutation has been accepted as a factor producing PVT. In general, the anticoagulants are recommended but this therapy should be used carefully in treating patients that associate coagulopathy or thrombocytopenia and esophageal varices. Acute PVT without bowel infarction has a good prognosis. In liver cirrhosis, the mortality due to hemorrhage is higher than in chronic PVT. Therefore, for the patients with PVT, the survival rate is decreased by 55% in two years, due to hepatic insufficiency. Regarding the treatment, LMWH (low molecular weight heparine) is the most utilized in patients with cirrhosis, non-malignancies, infections, or those who are awaiting a liver transplant. DOACs (direct-acting oral anticoagulants) may be used in the rest of the medical conditions, being safe and equal to LMWH.

Acute portal vein thrombosis unrelated to cirrhosis: A prospective multicenter follow-up study

Hepatology, 2010

Current recommendations for early anticoagulation in acute portal vein thrombosis unrelated to cirrhosis or malignancy are based on limited evidence. The aim of this study was to prospectively assess the risk factors, outcome, and prognosis in patients managed according to these recommendations. We enrolled 102 patients with acute thrombosis of the portal vein, or its left or right branch. Laboratory investigations for prothrombotic factors were centralized. Thrombus extension and recanalization were assessed by expert radiologists. A local risk factor was identified in 21% of patients, and one or several general prothrombotic conditions in 52%. Anticoagulation was given to 95 patients. After a median of 234 days, the portal vein and its left or right branch were patent in 39% of anticoagulated patients (versus 13% initially), the splenic vein in 80% (versus 57% initially), and the superior mesenteric vein in 73% (versus 42% initially). Failure to recanalize the portal vein was independently related to the presence of ascites (hazard ratio 3.8, 95% confidence interval 1.3-11.1) and an occluded splenic vein (hazard ratio 3.5, 95% confidence interval 1.

Non Cirrhotic Portal Vein Thrombosis: Diagnostic and Therapeutic Challenge

The Indonesian Journal of Gastroenterology, Hepatology, and Digestive Endoscopy

Portal vein thrombosis (PVT), the second most common cause of portal hypertension, can be found in cirrhosis and non-cirrhosis patients. Various factors can cause non-cirrhosis PVT, such as biliary infection. Upper gastrointestinal bleeding without sign of liver failure, must be considered as non-cirrhosis PVT manifestation. Combining physical, laboratory, endoscopic and radiological examination is needed to establish the diagnosis of PVT. The principle of PVT management consists of 3 keypoints. They are prevention and treatment of gastrointestinal bleeding, prevention of recurrent thrombosis and portal cholangiopathy therapy. Many aspect should be considered regarding the administration of anticoagulants in PVT patients, especially chronic PVT with cavernomas.
