Coronary-to-Bronchial Artery Fistula

Abstract

The incidence of CBF (0.61%) in this study is similar to those of a few cineangiographic studies in the literature. Our study showed that 64-MDCT coronary angiography is an accurate and noninvasive tool for detection of CBF.

Coronary to Bronchial Artery Fistula Causing Massive Hemoptysis in Patients with Longstanding Pulmonary Tuberculosis

“…However, this anastomosis may become enlarged and functional in various cardiovascular and chronic pulmonary diseases with an incidence of about 0.6%. Localized bronchiectasis is the most common condition associated with CBF; however, our three cases the CBFs were combined with pulmonary tuberculosis (2-4, 6). …”

“…Most cases of CBF are asymptomatic (2-5). However, the coronary steal phenomenon can cause dyspnea and chest pain, and is currently treated with endovascular embolization or surgical ligation (3-6).…”

Surgical Management of a Coronary-Bronchial Artery Fistula Combined with Myocardial Ischemia Revealed by 13N-Ammonia Positron Emission Tomography

“…According to a review article from the Netherlands, only 31 such fistulas were reported in the period from 2008 to 2013 [2]. Due to the advanced radiologic techniques that are currently used, such as MDCT, diagnosing coronary-bronchial artery fistula has become less complicated [3,4]. However, the etiology of coronary-bronchial artery fistula is uncertain.…”

“…Said et a l. [2] reported that chest pain was the most frequent symptom (63%) in their review, and Lee et al [4] suggested an association between the coronary steal phenomenon and chest pain in coronary-bronchial artery fistula patients. Hemoptysis (26%) and dyspnea (19%) are also frequent, and otherwise asymptomatic disease occurred in only 5 of 27 subjects (19%) [2].…”

“…Noninvasive contrast-enhanced MDCT is as useful as CAG for diagnosing coronary-bronchial artery fistula and identifying the course of a fistulous tract [4,6]. According to the reviews by Lee et al [4] and Said et al [2], coronary-bronchial artery fistula originated in the circumflex artery in 75% (6 of 8) and 61% (19 of 27) of cases, respectively. Transthoracic or transesophageal echocardiography is also helpful in detecting coexisting cardiac anomalies and assessing the cardiac function of the patient.…”
