Gastric varices (GV) are a type of upper gastrointestinal bleed, that are often associated with liver cirrhosis, portal hypertension or splenic vein thrombosis. GV are known to cause bleeding more severely than esophageal varices.
Presentation
Gastric varices (GV) are distended veins caused by increased hydrostatic pressure in the portal system, with multiple etiologies. Bleeding may be acute or chronic. GV are often associated with liver disease and may occur together with esophageal bleeds. The former do not bleed as often as esophageal varices, and spontaneous cessation of bleeding is possible, with a risk of re-bleeding [1].
There are a number of classification systems used for GV. One such classification divides them into those caused by isolated splenic vein thrombosis (SVT), and those due to portal hypertension, the latter being the more frequently reported cause [2]. GV can occur through the short gastric veins in the case of SVT, and in this particular etiology, management is challenging as there tends to be multiple varices occurring simultaneously. Other classification systems include the Sarin and the Japanese vascular classification systems, which consider numerous factors such as the vasculature, location, and appearance of varices [3] [4].
The majority of individuals that have isolated GV are asymptomatic, and the diagnosis is made incidentally. Rupture of GV causes painless bleeding from the upper gastrointestinal (GI) tract. GV tend to bleed copiously, thus some patients may present in hypovolemic shock, and fatalities are more common compared to esophageal bleeds [2]. In cases with left-sided portal hypertension, additional signs such as ascites and abdominal pain may be noticed [5]. Splenomegaly may be found on clinical examination.
Other possible presentations are hematemesis which may consist of bright red blood or coffee grounds vomitus, melena, or hematochezia which can signify a massive upper GI bleed. Occult bleeds may only be detected through biochemical testing of stool.
Entire Body System
- Fever
The patient developed mild fever and pain over the left upper quadrant and flank after the procedure. In addition to a Lipiodol-filled gastric varix, the imaging studies disclosed a wide spread of Lipiodol over the left peritoneal cavity. [ncbi.nlm.nih.gov]
- Surgical Procedure
Splenectomy combined with other surgical procedures was undertaken for 15 patients. The patients undergoing artery embolization or splencetomy achieved hemostasis. The survivors had no recurrent bleeding during a median 72-month follow-up period. [ncbi.nlm.nih.gov]

The most commonly employed procedure today is a transjugular intrahepatic portosystemic shunt (TIPS), which is a non-surgical procedure performed by radiologists (see below). In rare circumstances, a surgical shunt may be necessary. [liver.ca]
However, such a tube may provide life-saving tamponade pending decompression with a TIPS or surgical procedure. The tube is a flexible NGT with one gastric balloon and one esophageal balloon. [merckmanuals.com]
- Pallor
Physical examination will likely reveal hypotension or shock (in severe cases), pallor and stigmata of chronic liver disease such as spider angiomatas, palmar erythema, gynecomastia, or splenomegaly. [clevelandclinicmeded.com]
Respiratoric
- Aspiration
Thirty to 50 minutes later, the outflow is coil-embolized and as much as possible of the remaining sclerosant is aspirated via the catheter before deflating the balloon and withdrawing the catheter. [massgeneral.org]
To avoid bronco aspiration the patient must be with endotracheal tube. [gastrointestinalatlas.com]

Psychiatrical
- Withdrawn
After 15 to 30 seconds once the CYA is solidified and the risk of bleeding by puncturing decreases, the needle will be withdrawn. Finally obliteration of the vessel will be evaluated using Doppler imaging 5 minutes later. [ichgcp.net]
The needle is withdrawn and the area assessed for bleeding. The procedure can be repeated if the varix is large. Suction should not be used to avoid risk of suctioning glue that might be external to the varix. [nursingcenter.com]
As the needle is withdrawn from varix, a steady stream of the flush solution is aimed at the puncture site. [ncbi.nlm.nih.gov]

Workup
In patients with gastric varices, it is important to investigate for the common underlying conditions. If varices are actively bleeding, the workup includes both diagnostic as well as therapeutic interventions, usually in the form of endoscopy. This is done after hypovolemia has been addressed with careful intravenous fluid therapy.
Laboratory investigations for liver disease, such as liver function tests and clotting studies, are usually conducted. Biopsy followed by histological analysis of liver tissue may also be carried out. Blood typing and crossmatching are also useful, as some people may require transfusion.
During the endoscopic evaluation, GV may be more adequately visualized by the insertion of a nasogastric tube for gastric lavage, endoscopic suction, or the use of prokinetic drugs to accelerate gastric emptying.
Radiological techniques are employed in the evaluation of the veins of the portal system. The modalities often used are:
- Endoscopy: This has a good detection rate, reported to be as high as 90% [6]. It is accurate in localizing the GV, and identifying non-variceal upper GI bleeding.
- Angiography.
- Ultrasonography: This can either be done via the trans-abdominal or endoscopic route and is instrumental in detecting splenic vein and pancreas pathologies. Endoscopic ultrasound is preferred, as it is more accurate [7].
- Computed tomography (CT) portography: This is carried out as a contrasted study, used in the evaluation of the portal system.
- Magnetic resonance imaging (MRI) [8].
X-Ray
- Atelectasis
Any plain radiographic findings suggesting paraesophageal varices should be followed up with CT scanning or a barium study to differentiate the findings from a hiatal hernia, posterior mediastinal mass, or other abnormality (eg, rounded atelectasis). [emedicine.medscape.com]
Biopsy

Epidemiology
There are multiple other terms used globally, and although there are reported differences in etiology, epidemiology, and hepatic pressures, these various presentations likely reflect the vast spectrum of the condition itself and not the distinct diseases [cureus.com]
Pathophysiology

Eight of the 14 patients had adequate clinical and/or radiologic follow-up to suggest the pathophysiology of the varices. Seven had evidence of portal hypertension, and the remaining patient had evidence of splenic vein obstruction. [link.springer.com]
When compared with esophageal varices, GV differs in natural history, morphology, and pathophysiology. GV is rare occurring in about 33% of cases. [news-medical.net]
Prevention
Can also be used to prevent releeding. [1] BRTO is not suitable for gastric varices that lack a main draining vein, as they cannot be catheterized. [4] Prevention of rebleed (secondary prophylaxis) - Non selective β-blockers [1] These medications reduce [explainmedicine.com]

There was low quality evidence for the prevention of re-bleeding (RR 0.60; 95% CI 0.41 to 0.88). [ncbi.nlm.nih.gov]
In the United States, the primary approach to prevent re-bleeding is the use of a transjugular intrahepatic postosystemic shunt (TIPS) to decompress the portal circulation. [massgeneral.org]
