A Rare but Reversible Cause of Hematemesis: "Downhill" Esophageal Varices

Downhill esophageal varices: a systematic review of the case reports

Aim: The etiologies, presentation, and management of downhill varices in the era of modern medicine are relatively under-explored and mostly limited to case reports or case series. Methods: Published case reports/series of patients ≥ 18 years old with proven/probable downhill esophageal varices were searched on Ovid MEDLINE and Ovid EMBASE for all published cases up to January 2021. Results: The mean age was 50.9 (standard deviation ± 17.6) years old for all downhill variceal cases. End-stage renal disease was the most common comorbidity (43.9%), followed by thyroid disease (12.2%), Behçet’s disease (9.8%), and pulmonary hypertension (7.3%). Dialysis catheters, central venous grafts, or additional catheters were additional risk factors (51.2%). Variceal bleeding presenting as hematemesis, melena, or both was the most common presenting symptom (80.5%). Conclusions: Dialysis catheter-associated superior vena cava obstruction resulted in an increased risk of downhill varices. Other causes include thyroid malignancies, pulmonary hypertension, and Behçet’s disease.

Haemorrhagic shock leading to death due to ruptured esophageal varices: An autopsy based case report

Introduction

and importance: Ruptured esophageal varices are fatal and cause haemorrhagic shock and consequently death if no immediate intervention is instituted to arrest bleeding. The role of forensic pathologists in investigating cases of sudden unexpected deaths is of paramount importance. Upon medico-legal work ups by forensic pathologists, autopsy would shed light to the exact cause of death as to whether it is natural or unnatural.

Case presentation

We are reporting an unusual case of an elderly man with alcoholic liver cirrhosis who succumbed to sudden death following ruptured esophageal varices which led to haemorrhagic shock.

Clinical discussion

Clinical autopsy was carried out to establish the cause of death. Tissue sections from the healed pathologically fractured bone, liver, prostate and esophagus were taken for histological evaluation. The bone tissue showed relative reparative changes and the prostate tissue showed hyperplasia of both stroma and epithelial components. The tissue from the esophagus showed proliferating distended, engorged vascular structures and some were thrombosed (photograph 3). Liver biopsy showed destruction of the normal liver parenchyma by both micro and macro nodular formation which was marked by the thick broad fibrous bands. A conclusive diagnosis of hemorrhagic shock secondary to ruptured esophageal varices caused by alcoholic liver cirrhosis was established as the cause of death.

Conclusion

Esophageal varices can be the likely cause of sudden death upon rupturing. Rupturing of esophageal varices in individuals with a known long-standing history of alcoholism must always be considered in order to prevent haemorrhagic shock from ensuing.

•

Ruptured esophageal varices are fatal and cause haemorrhagic shock.

•

Decompensated liver cirrhosis is a common cause of upper gastrointestinal bleeding.

•

Esophageal varices represent the most important complications of portal hypertension.

•

Alcoholic liver cirrhosis is associated with a significantly higher risk of variceal bleeding than from other causes.

•

Poor liver function contributes to abnormalities in coagulation.

Hematemesis, a Rare Presentation for Downhill Esophageal Varices

Downhill esophageal varices (DEV) are a rare form of esophageal varices associated with superior vena cava obstruction. Obstruction leads to retrograde blood flow through collateral venous channels, including the esophageal venous plexus, to redirect blood flow to the right atrium via the inferior vena cava. This leads to the formation of DEV. It is a rare phenomenon to have gastrointestinal bleeding, especially hematemesis, on a patient's first presentation with this disease process. We describe such a case here involving a patient with DEV secondary to metastatic renal cell carcinoma presenting with hematemesis.

Downhill esophageal varices: a therapeutic dilemma

Esophageal varices can cause life-threatening complications and are most often a sequela of liver disease. Although a rare cause of gastrointestinal bleeding, downhill variceal bleeding secondary to superior vena cava (SVC) obstruction should be considered in the differential diagnosis for patients with upper gastrointestinal hemorrhage. We discuss two such cases of downhill esophageal varices presenting with hematemesis in patients with end stage renal disease and no history of cirrhosis. These varices were thought to be secondary to SVC occlusion caused by complications from previous dialysis catheters. However, their difficult anatomy posed a significant challenge to the therapeutic interventions.

Are Downhill Varices an Overlooked Entity of Upper Gastrointestinal Bleedings?

Aim

Downhill varices are not so safe as thought and can lead to life-threating or mortal bleeding complication, even if rare. In order to draw attention to this topic, we analysed 129 patients.

Materials and Methods

We evaluated the electronic endoscopy data records of all patients undergoing upper gastrointestinal endoscopy over a nine-year period from January 2004 till December 2012, within a retrospective approach. The primary endpoints, incidence, causes, kind of resulting upper gastrointestinal bleeding, and the severity of the bleeding were evaluated. Secondary endpoints were the evaluation of the size of downhill varices and a comparison of the risk of bleeding between downhill varices and uphill varices.

Results

Downhill varices were identified, described, and/or documented in 129 patients of 25,680 upper gastrointestinal endoscopies. 26 patients had central venous catheter or port implantation, 22 patients had a history of an implantation of a cardiac pacemaker, 7 patients had severe pulmonary artery embolism, and 4 patients had severe chronic obstructive pulmonary disease. Two patients had mediastinal tumors, and one patient had a large retrosternal goiter as a possible cause of the vena cava syndrome. Altogether, 62 patients were related to a vena cava superior syndrome; 67 were not.

Conclusions

Downhill varices can be seen with an incidence of 0.5%. Therapeutic means are the banding therapy as a safe and effective option. Severe bleedings associated with downhill varices can be mortal. Severe forms of downhill varices should be examined in relation to the origin in order to start a specific therapy.
