With a central motif of the biologic dichotomy of vascular tumors and vascular malformations, this book is organized into chapters which address clinical presentation, diagnostic imaging, molecular genetics, pathogenesis, histopathology, and management [books.google.de]

We present a case of 12-year-old boy presenting with recurrent lower gastrointestinal bleeding simulating ulcerative colitis. [jpss.eu]

Common presentation is malena or hematochezia as bleeding is usually low grade. [saudijgastro.com]

It can present as a small submucosal nodule with arterial enhancement (image) and sometimes they lead to intussusception. GIST Typical GIST in the ileum presenting as an exophytic tumor. [radiologyassistant.nl]

We report a 39-year-old Egyptian man presenting with multiple jejunal phlebectasia, liver haemangioma and port-wine naevus. [ncbi.nlm.nih.gov]

During workup, packed red blood cells (RBCs) were transfused. The level of hemoglobin increased to 9.3 g/dL and remained stable. Dyspnea was relieved, with stable vital signs. He was discharged with the instruction to take aspirin only. [e-sciencecentral.org]

For patients who cannot undergo endoscopic treatment, transcatheter angiography and embolization are encouraged as alternative treatments [ 13 ]. [e-sciencecentral.org]

Angiodysplasia Treatment The treatment of angiodysplasia depends on the nature of symptoms, the hemodynamic stability and the severity of bleeding from the rectum. [primehealthchannel.com]

Large AVMs may require multiple embolization procedures on separate days for complete treatment. For example, two or three treatments may be given at intervals of two to six weeks. [radiologyinfo.org]

The treatment measures for Colonic Arteriovenous Malformation may include the following: Endoscopic cautery using techniques such as argon plasma coagulation Arterial embolization Medications to help with coagulation, such as antifibrinolytics, and treatment [dovemed.com]

Hereditary Hemorrhagic Telangiectasia The treatment was successful, the patient stopped bleeding, we expect the long-term outcome. These treatments were successful and the Gi bleeding stopped, pending treatment to stop nosebleeds. [gastrointestinalatlas.com]

Prognosis Life expectancy is largely normal, depending on the severity of the malformation and thus the likelihood of complications. [ 1 ] Possibly about 10% of patients develop a pulmonary embolism. [patient.info]

Alternatively, in patients with refractory bleeding Interventional Radiology may be consulted for an angiogram with subselective embolization. [7] Prognosis [ edit ] The mortality rate for Dieulafoy's was much higher before the era of endoscopy, where [en.wikipedia.org]

[…] gastrointestinal or genitourinary hemorrhage if there is visceral involvement (see above) If capillary malformations are large enough, they may sequester platelets, possibly leading to the Kasabach-Merritt syndrome (consumptive coagulopathy) Treatment and prognosis [radiopaedia.org]

Among the treatment modalities, surgery can be considered when endoscopic or angiographic treatment is not suitable, or when the patient has poor prognosis factors. [e-sciencecentral.org]

Acute upper gastrointestinal hemorrhage has an incidence of 50–150/100,000 cases each year and a mortality rate of 7–10%. 2,3 The etiology of the vast majority of upper gastrointestinal hemorrhages is peptic ulcer disease. [gastroenterologyandhepatology.net]

(Etiology) The exact cause of Colonic Arteriovenous Malformation is unknown, but studies indicate that it is a congenital malformation The condition arises owing to malformations in arteries and veins of the large intestine (colon). [dovemed.com]

The most likely etiologies are broken down by age group. [wjes.biomedcentral.com]

Selective arteriography of the celiac trunk and the superior mesenteric artery was performed in eight patients (89%) and enabled the etiological diagnosis in all cases. [em-consulte.com]

Bleeding Dieulafoy lesions of the small bowel: a systematic study on the epidemiology and efficacy of enteroscopic treatment. Gastrointest Endosc. 2011; 74 (3): 573-80[ DOI ][ PubMed ] 12. Prachayakul V, Deesomsak M, Aswakul P, Leelakusolvong S. [ijp.tums.pub]

Visceral involvement is thought to be more common than previously supposed, occurring in perhaps 20% of patients. [ 3 ] Aetiology and epidemiology The cause is is unknown. [patient.info]

EPIDEMIOLOGY • Upper GI bleed remains a major medical problem. • About 75% of patient presenting to the emergency room with GI bleeding have an upper source. • In-hospital mortality of 5% can be expected. • The most common cause are peptic ulcer, erosions [slideshare.net]

Epidemiologic data from Europe indicated an upper GI bleeding annual incidence of 48 to 145 per 100,000 population in the 1960s and 1970s [Gilbert,1990]. [uwgi.org]

[…] endoscopic modality in the treatment of GAVE and radiation proctitis. [28] GAVE is often associated with systemic illnesses, such as cirrhosis of the liver, autoimmune connective tissue disorders, bone marrow transplantation, and chronic renal failure. [29] Epidemiology [emedicine.medscape.com]

Pathophysiology [ edit ] Dieulafoy's lesions are characterized by a single large tortuous small artery [5] in the submucosa which does not undergo normal branching or a branch with caliber of 1–5 mm (more than 10 times the normal diameter of mucosal capillaries [en.wikipedia.org]

Of note, the aforementioned pathophysiologic mechanisms responsible for the development of cecal lesions are unlikely to apply to lesions in the upper GI tract, despite being morphologically identical. [emedicine.medscape.com]

Technically, successful embolization requires the catheter be placed in a precise position to prevent injuring normal tissue. [radiologyinfo.org]

A dose-reponse effect was noted in the prevention of gastric, but not duodenal, ulcer. [uwgi.org]

However, our patient received surgery because the number and the location of the lesions—10 polypoid lesions between the proximal and distal jejunum—prevented endoscopic treatment. [e-sciencecentral.org]

One is also advised to refrain from using nonsteroidal anti-inflammatory drugs in this case to prevent the condition to aggravate. [primehealthchannel.com]
