Aortoesophageal fistula involving the central aortic arch salvaged with emergent percutaneous TEVAR, great vessel coverage and in vivo graft fenestration

In Situ Fenestrated Thoracic Endovascular Repair Using the Upstream Peripheral Go BackTM Re-Entry Catheter

PURPOSE

The aim is to present a case of in situ fenestrated thoracic endovascular repair, using a re-entry peripheral catheter, needing urgent repair due to recurrent episodes of hemoptysis because of an aorto-bronchial fistula after previous thoracic endovascular aortic repair (TEVAR).

TECHNIQUE

A 74-year-old male with a previous TEVAR presented with hemoptysis, fever, and cachexia. An aorto-bronchial fistula and type Ia endoleak were depicted on computed tomography angiography (CTA). Due to the patient's frail general condition, a proximal TEVAR extension was planned, prior to thoracotomy for debridement, and long-term antibiotics. An in situ fenestrated TEVAR was performed to provide proximal sealing and revascularize the left common carotid and subclavian arteries. For fenestration creation, an Upstream Peripheral Go Back catheter (Bentley, Hechingen, Germany) was used. The Go Back catheter has been approved as a re-entry tool for complex peripheral arterial revascularization. In this case, both fenestrations were successfully created. Proximal seal and target vessel patency were confirmed on CTA. Thoracotomy confirmed aortic exclusion. A wedge lobectomy was performed in combination with pediculated omentectomy to exclude the exposed endograft.

CONCLUSION

In urgent cases, where custom-made thoracic devices are unavailable, in situ fenestrations with the Go Back catheter are an alternative to laser fenestrations.

CLINICAL IMPACT

Fenestrations are often required in acute TEVAR to achieve a proximal seal in the arch. In situ fenestrations with the Go Back catheter are an alternative to laser fenestrations and PMEGs in this setting.

Total Aortic Arch Endograft and Double In Situ Fenestration for Aortobronchial Fistula

This case highlights the challenges of treating an aortobronchial fistula. Emergent total aortic arch stent grafting is limited by inability to maintain cerebral perfusion during in situ fenestration. We describe the application of a new technique to maintain cerebral perfusion using a gutter balloon adjacent to the aortic endograft while great vessel fenestrations are being performed in an urgent setting.

Emergencies during oncovascular surgery: Strategies and pitfalls

In a growing number of pathologies, vascular invasion is no longer considered a contraindication for surgery with a curative intention. This has led vascular surgeons to be more involved in the treatment of pathologies that they are not used to. These patients should be managed in a multidisciplinary manner. New types of emergencies and complications have emerged. Emergencies in oncovascular surgery are mostly avoidable with careful planning and good collaboration between oncological surgeons and a dedicated vascular surgery team. The operations often involve difficult vascular dissection and complex reconstructive techniques in a potentially contaminated and irradiated field, and the risk of postoperative complications and blow out is increased. However, after a successful operation and immediate postoperative course, the patients often recover faster than the typical fragile vascular surgical patient. This narrative review focuses on emergencies that are more or less specific to oncovascular procedures. A scientific approach and international collaboration are needed, so that we can better identify which patients should be operated, what problems to anticipate and could be avoided with better planning, and which solutions improve patient outcome.

Case report: Aortoesophageal fistula-an extremely rare but life-threatening cardiovascular cause of hematemesis

Aortoesophageal fistula (AEF) is an extremely rare cardiovascular etiology of hematemesis and upper gastrointestinal bleeding. As such, its recognition and diagnosis are challenging and may be delayed when such patients present to the emergency department (ED). Without timely surgical intervention, AEF is almost always fatal. Awareness of AEF as a possible diagnosis and consequently early identification of these patients presenting to the ED are therefore crucial in optimizing clinical outcomes. We report a 45-year-old male presenting to the ED with the classical triad of an AEF (Chiari's triad)-midthoracic pain or dysphagia, a sentinel episode of minor hematemesis, then massive hematemesis with risk of exsanguination. The case report highlights the importance of considering the differential diagnosis of AEF when evaluating patients presenting to the ED with hematemesis, especially if they have predisposing risk factors such as prior aortic or esophageal surgeries, aortic aneurysms, or thoracic malignancies. Patients suspected of having AEF should be prioritized for early computed tomography angiography to expedite diagnosis and treatment.

Chicken Bone Ingestion Leads to Aortoesophageal Fistula With Catastrophic Bleeding

Aortoesophageal fistula (AEF) is an uncommon, but potentially fatal cause of upper gastrointestinal bleeding. Aortoesophageal fistulas caused by foreign body ingestion are rare but devastating. The classic clinical triad of AEF consists of mid-thoracic pain or dysphagia, a herald episode of hematemesis, followed by fatal exsanguination after a symptom-free period (Chiari's triad). Computed tomography angiography (CTA) is the preferred diagnostic tool for identifying AEF and is substantially more sensitive than upper endoscopy for detecting AEF. Endoscopy can detect AEF as it might show pulsatile blood, pulsatile mass, hematoma, or adherent blood clot in the esophagus, or a deep esophageal tear. However, endoscopy has a low sensitivity and may delay definitive treatment. Several management options for AEF have been suggested; however, the definitive treatment is surgery performed on the thoracic aorta and esophagus, including esophagectomy, surgical replacement of the thoracic aorta, thoracic endovascular aortic repair, or omental flap. We report a case of a 63-year-old man who presented with hematemesis 2 weeks after chicken bone ingestion.

Fatal bleeding due to an aorto-esophageal fistula: A case report and literature review

BACKGROUND

Aorto-esophageal fistula is an extremely rare cause of acute upper gastrointestinal bleeding (UGIB).

CASE SUMMARY

We present a case of an 80-year-old woman with esophageal cancer who was admitted to our department with hemorrhagic shock due to UGIB. During the diagnostic procedure, emergency computed tomography angiography was performed and confirmed aorto-esophageal fistula. Interventional radiologists inserted a stent graft into the aorta, successfully closing the fistula. Unfortunately, the patient later died of heart failure following irreversible hemorrhagic shock. Autopsy confirmed the aorto-esophageal fistula, which formed 1 cm below the distal edge of the stent previously inserted into the esophagus for a malignant stricture.

CONCLUSION

There are very rare causes of UGIB. Although clinical decisions are made during the diagnostic workup of these patients, we must be aware of the limitations of various therapeutic options, even the most contemporary.
