  • Massive upper gastrointestinal hemorrhage with normal findings on arteriography: value of prophylactic embolization of the Left Gastric Artery.
    AJR. American journal of roentgenology, 1992
    Co-Authors: E. V. Lang, D. Picus, M. V. Marx, Marshall E. Hicks, Gerald W. Friedland
    Abstract:

    During a 5-year period, 13 patients who presented with massive upper gastrointestinal hemorrhage had normal findings on arteriography. Seven had prophylactic embolization of the Left Gastric Artery, and six had conservative therapy. Normal angiographic findings were associated with clinical cessation of bleeding in 12 of 13 patients. Lesions not treated by embolization or other invasive therapy had a high rate of massive recurrent hemorrhage (four of six). Of lesions subsequently found to be supplied by the Left Gastric Artery, two of four cases not treated by embolization or surgery had clinically significant recurrent hemorrhage, whereas none of six cases treated by embolization had recurrent hemorrhage. Prophylactic embolization of the Left Gastric Artery appears warranted when (1) there is definite prior identification of a lesion in the Left Gastric Artery territory or (2) there is no prior localization of a lesion but the patient is at risk for multiorgan failure if bleeding recurs.

  • Bariatric Left Gastric Artery Embolization for the Treatment of Obesity: A Review of Gut Hormone Involvement in Energy Homeostasis.
    AJR. American journal of roentgenology, 2016
    Co-Authors: Kevin Anton, Tariq Rahman, Ashok Bhanushali, Aalpen A. Patel
    Abstract:

    OBJECTIVE. The global population is becoming more overweight and obese, leading to increases in associated morbidity and mortality rates. Advances in catheter-directed embolotherapy offer the potential for the interventional radiologist to make a contribution to weight loss. Left Gastric Artery embolization reduces the supply of blood to the Gastric fundus and decreases serum levels of ghrelin. Early evidence suggests that this alteration in gut hormone balance leads to changes in energy homeostasis and weight reduction. The pathophysiologic findings and current evidence associated with the use of Left Gastric Artery embolization are reviewed. CONCLUSION. The prevalence of obesity continues to increase at an alarming rate, and, thus far, advances in medical management have been relatively ineffective in slowing this trend. Lifestyle modifications such as diet and exercise are effective initially, but most patients regain the weight in the long term. Bariatric surgery is the most effective strategy for ach...

  • Weight Loss Following Left Gastric Artery Embolization in a Human Population without Malignancy: A Retrospective Review
    Journal of obesity and weight loss therapy, 2015
    Co-Authors: Kevin Anton, Tariq Rahman, Ashok Bhanushali, Luis L. Nadal, Gregory Pierce, Aalpen A. Patel
    Abstract:

    Objective: Recent evidence suggests embolization of the Left Gastric Artery, which provides the predominant arterial supply to the Gastric fundus, may affect energy homeostasis through alterations in ghrelin production. The purpose of this study is to evaluate post-procedural weight loss following Left Gastric Artery embolization (performed for reasons other than for weight loss) in patients without malignancy. Materials and Methods: A retrospective review of patients who underwent arterial embolization for acute upper gastrointestinal hemorrhage between January 2002 and January 2014 was conducted. A study group of 10 patients who underwent Left Gastric Artery embolization and control group of 22 patients who underwent embolization of a different mesenteric or visceral arterial branch for non-tumoral acute gastrointestinal bleeding were collected. Their electronic medical records were reviewed and data points for height, weight, and body mass index were collected at 1-, 4-, 8-, and 12-month post-procedural time points. Exclusion criteria included age less than 18 years and documented history of malignancy. Results: The Left Gastric Artery embolization group had a significantly greater reduction in body mass index compared with the control group at 1 month (-9.8% vs. -4.0%, p=0.042) and 4 months (-11.7% vs. +0.1%, p=0.033). No significant change was demonstrated at 8 months (-8.6% vs. -1.7%, p=0.32) and 1 year (-5% vs. +2.6%, p=0.42) compared with controls. Conclusion: Left Gastric Artery embolization provides early post-procedural weight loss that may persist for at least 1 year. Further studies will better elucidate the role of Gastric Artery embolization in the management of bariatric patients.
