The literature describes a wide range of complications, including aortooesophageal fistula, [9,10] which commonly presents as a herald bleed followed by a fatal upper gastrointestinal bleed, bilateral vocal cord paralysis, [9] tracheo-oesophageal fistula, [11] commonly presenting as aspiration pneumonia, oesophageal necrosis[6] and oesophageal stenosis.
The majority of these patients presented with a herald bleed (93%) (1).
Aortoesophageal fistula presents with a Chiari's triad of chest pain, a symptom-free interval, and a transient, self-limiting "herald bleed." (4) When untreated, this series of symptoms precedes a fatal hemorrhage.
Use of plastic tracheostomy tubes, low pressure-high volume cuffs, tube placement at second or third tracheal rings and flexed positioning of neck may prevent formation of TIF.4 A 'sentinel' or 'herald bleed' is an early warning sign which is reported in more than 50% of patients who developed subsequent massive delayed haemorrhage.5 A sentinel bleed renders the need of close monitoring and immediate medical attention.
The first bleedings are known as "herald bleeds" and they are usually mild and self-limited.
