Endovascular stent graft repair of aortopulmonary fistula. (1/89)

Two patients who had aortopulmonary fistula of postoperative origin with hemoptysis underwent successful repair by means of an endovascular stent graft procedure. One patient had undergone repeated thoracotomies two times, and the other one time to repair anastomotic aneurysms of the descending aorta after surgery for Takayasu's arteritis. A self-expanding stainless steel stent covered with a Dacron graft was inserted into the lesion through the external iliac or femoral artery. The patients recovered well, with no signs of infection or recurrent hemoptysis 8 months after the procedure. Endovascular stent grafting may be a therapeutic option for treating patients with aortopulmonary fistula.  (+info)

Surgical treatment of a coronary artery fistula with concomitant saccular coronary artery aneurysm: a case report. (2/89)

An extremely rare case of a coronary artery fistula with a concomitant saccular aneurysm is presented. A 65-year-old woman, who had a history of chest bruising 5 years earlier, suffered from chest pain, which was diagnosed as being due to left coronary artery-pulmonary artery fistulae concomitant with a giant saccular coronary artery aneurysm. Suture closure of the afferent coronary artery to the aneurysm, aneurysmorrhaphy, and transpulmonary closure of coronary artery-pulmonary artery fistulae were performed. The postoperative course was uneventful and the patient was well at 3 months after the operation. Because the risk of surgery appears to be less than the potential development of fatal complications, it is recommended for the treatment of coronary artery fistula with a concomitant saccular aneurysm.  (+info)

Doppler detection of arterio-arterial anastomoses in monochorionic twins: feasibility and clinical application. (3/89)

The accuracy of in-vivo detection of arterio-arterial anastomoses (AAA) in monochorionic (MC) twins and its predictive value for twin-twin transfusion syndrome (TTTS) was assessed in 105 consecutive MC twins scanned at fortnightly intervals. AAA were sought using spectral and colour energy Doppler and ultrasound findings were compared with placental injection studies. AAA were identified in vivo in 59 (56%) pregnancies and at injection study in 68 (65%). The overall sensitivity and specificity was 85 and 97.3% respectively for the detection of AAA. Detection rates were higher at later gestations, with anterior placentae and with larger diameter AAA. The median insonation time to detect an AAA was 10 min (range 1-30). Where an AAA was identified, 15% of pregnancies (nine of 59) developed TTTS compared to 61% (28 of 46) when no AAA was seen (odds ratio 8.6). We conclude that AAA can be detected in vivo with high sensitivity and specificity without undue prolongation of scanning times and have a role in risk stratification in the antenatal assessment of MC twins.  (+info)

Local pulmonary malformation caused by bilateral coronary artery and bronchial artery fistulae to the left pulmonary artery in a patient with coronary artery disease. (4/89)

At 10 years of age and again at 25, our patient had been treated for pulmonary tuberculosis due to the presence of a localized pulmonary shadow. Coronary angiography at age 59 revealed 3 fistulous communications: from the right and circumflex coronary arteries and from the left bronchial artery. All 3 emptied into the same recipient artery, the distal part of a left pulmonary artery branch, which produced substantial left-to-right shunt. On computed tomography, cystic formations could be seen in the pulmonic area. The pulmonary tuberculosis for which this patient had been treated in his youth was in the same part of the lung where the shunt was discovered. Our conclusion is that the initial diagnosis was in error.  (+info)

Prominent systolic coronary flow in a coronary artery fistula with a giant aneurysma. (8/89)

A 68-year-old Japanese woman was admitted to hospital because of chest oppression during exertion. Coronary angiography showed a coronary artery fistula with a giant aneurysm, which originated from both the left anterior descending (LAD) and right coronary arteries. We investigated coronary blood flow velocity using the Doppler guide wire technique. The coronary flow pattern showed a very prominent systolic component, whereas the diastolic flow components were nearly normal before the operation at the LAD site proximal to the coronary artery fistula. This pattern returned to normal after the operation. This report describes the relationship between the coronary steal phenomenon and coronary flow dynamics investigated directly using the Doppler guidewire technique.  (+info)

Coronary-pulmonary artery fistula is an uncommon cardiac anomaly, usually congenital. Most coronary-pulmonary artery fistulas are clinically and haemodynamically insignificant and are usually found incidentally. This report describes a case of complex coronary-pulmonary artery fistula with two feeding vessels of separate origins: one from the proximal part of the left anterior descending artery and another arising from the right aortic cusp. The complex anatomy of the fistula was shown in detail by multidetector computed tomography using multiplanar reconstruction and 3D volume rendering techniques.. ...

Coronary artery fistulae (CAF) are rare anomalies. They are vascular communications between the coronary arteries and other cardiac structures, either cardiac chambers or great vessels. There can be considerable variation in the course of a coronary artery fistula. We report a case of a coronary artery fistula between the left circumflex coronary artery and the right and left atria. CAF are often diagnosed by coronary angiogram, however with the advent of new technologies such as Coronary Computed Tomography Angiography (Coronary CTA) the course and communications of these fistulae can be delineated non-invasively and with greater accuracy.
A 60-year-old man with end-stage heart failure underwent orthotopic heart transplantation. Before transplantation, he had elevated pulmonary artery (PA) pressures (60/17 mm Hg, mean PA 35 mm Hg) and pulmonary vascular resistance (PVR) (6.6 Wood units).. Following transplantation, he initially did well, with normalization of PA pressures (27/13 mm Hg, mean PA 20 mm Hg). Several months later, however, he developed overt right heart failure. Invasive hemodynamic evaluation demonstrated severe pulmonary hypertension (92/51 mm Hg, mean PA 66 mm Hg) with a PVR of 10 Wood units. There was no evidence of allograft rejection or pulmonary embolism. Transthoracic echocardiogram demonstrated right ventricular (RV) systolic dysfunction and enlargement. Color flow Doppler imaging demonstrated continuous flow from the ascending aorta into the main PA. The anatomy was confirmed by computed tomographic angiographic imaging (Fig. 1). ...

Coronary artery fistulas are rare and vary widely in their morphological appearance and presentation. This paper presents experience of catheter closure of coronary artery fistulas in 40 patients. Catheter closure was performed with a variety of tech
The LAD fistula to the MPA was ligated after constructing the left internal mammary artery to the LAD graft. However, the RCA fistula was left alone due to its unfavorable location for exposure or ligation, and postoperative transcatheter embolization was planned.. Although various imaging modalities have been used, intraoperative 2D TEE has been used for diagnosis and evaluation of coronary artery fistulae.1-3 However, the limitations of 2D TEE make angiography the preferred method of visualizing this pathology.4 Manipulating the TEE probe to acquire appropriate 2D images and interpreting the images accurately are challenging in complex fistula pathology. Even under favorable conditions, greater effort may be required to obtain and combine multiple 2D images. The X-plane mode may partly overcome the limitation of 2D TEE imaging; it instantaneously produces an additional 2D image and multiplane angle, and angulation of the additional image to the original can be changed by adjusting knob and ...

A 78-year-old woman presented with an abrupt onset of chest pain and dyspnea. Fourteen years before admission, she had undergone aortic root and valve replacement with the Bentall-de Bono continuous-suture wrap-inclusion technique because of an aneurysm of the ascending aorta and severe aortic valve regurgitation. Physical examination revealed signs of congestive heart failure and poor peripheral perfusion. The admission radiograph (Figure 1) showed lung congestion predominantly in the right lung, bilateral pleural effusion, elevation of the left hemidiaphragm, tracheal shift to the right side, and aortic arch calcification. The ECG (Figure 2) revealed sinus tachycardia at 111 bpm, frequent premature atrial beats, and repolarization abnormalities that consisted of T-wave inversion in the inferolateral leads. Transthoracic echocardiography showed a hypertrophied left ventricle with normal systolic function. Computed tomography disclosed a huge pseudoaneurysm of the ascending aorta (maximum ...
We report the case of a 54-year-old man, waitlisted for lung transplantation with a diagnosis of end-stage diffuse bronchiectasis. On arrival at the catheterization laboratory for coronary angiography prior to transplantation, the patient developed a hypertensive crisis (BP 200/110mmHg), at which stage he reported habitually uncontrolled blood pressure. Coronary angiography revealed coronary arteries free of lesions and a coronary artery fistula emerging from the left common trunk (LCT), 3mm in caliber at the proximal end and 2mm at the most distal end (Video 1, Appendix), with drainage to the left pulmonary artery, causing hemodynamic alterations in the form of high cardiac output (thermodilution 7.86l/min). Increased pulmonary pressures (mPAP 71mmHg, PVR 5.5 Wood units [WU]) associated with pulmonary hyperflow and significant diastolic dysfunction due to hypertensive heart disease evidenced in the rest of the study data (mean PCP 35mmHg and left ventricular end-diastolic pressure [LVEDP] ...

Coronary artery fistulae (CAF) represent an abnormal communication bypassing the myocardial capillary bed between a coronary artery and either a cardiac chamber (coronary-cameral CAF) or a vascular structure from systemic or pulmonary circulation (coronary-vascular CAF). CAF represent a congenital anomaly in 0.2% of the population, but are more frequently found in heart transplant recipients (8%), mostly as coronary-right ventricle (RV) CAF caused by endomyocardial biopsy used for monitoring of rejection1,2. Other complications of myocardial biopsy include perforation of the RV wall and tricuspid valve damage2. Several case reports have shown successful transcatheter closure of CAF3,4. We aimed to analyse .... ...
Systemic artery-pulmonary artery shunts have been made in dogs and the relation between pulmonary artery pressure and blood flow and the development of vascular lesions has been studied. Arteriolar medial hypertrophy and intimal proliferation are not necessarily incited by a large blood flow, but such lesions are more readily induced by an end-to-end than by an end-to-side type of shunt. Intimal proliferation is not associated with stainable alterations in elastic tissue or lipid infiltration. Vascular lesions do not readily regress when the inciting factor is removed.. ...
2 Departments of Cardiovascular Surgery, Başkent University Faculty of Medicine, Ankara, Turkey. DOI : 10.24953/turkjped.2020.04.011 Background and objectives. In this study, we aimed to review the treatment options and long-term problems of patients who were diagnosed with coronary artery fistulae (CAF) in our institution. We also tried to determine the most appropriate time for treatment of this condition.. Method. From 2000 to 2018, the medical records of 56 patients (33 males and 23 females) who had CAF diagnoses were retrospectively reviewed.. Results. The mean age of the patients at the time of diagnosis was 3.9 ± 4.6 years (range, 1 month to 18 years) and the mean duration of the follow-up period was 7.4 ± 4.5 years (range, 1 year to 17.5 years). The right coronary artery (RCA) was the most common origin site for CAF, the left main coronary artery (LMCA) was the second most common origin site whereas the left anterior descending coronary artery (LAD) was the third most common origin ...
Coronary artery fistulas (CAFs) are infrequent congenital malformations, although some may be acquired: iatrogenic (during thoracic surgery or PCI) or traumatic. The incidence of CAFs has not been well defined but it is found in less than 0.2% of angiographic examinations. CAFs, even if rarely, may cause heart failure, spontaneous intrapericardial rupture or myocardial ischemia due to coronary steal phenomenon. The literature reports very few cases of patients where a CAF was associated with a coronary artery disease (CAD). The consequences of this association on coronary haemodynamics and myocardial blood flow (BF) was poorly investigated ...

Coronary-to-cardiac chamber fistulae and coronary aneurysms are potential complications after heart transplantation. In the setting of exercise intolerance and large fistulae at major coronary vessels, covered stents may provide an effective interventional strategy.
Case Reports in Vascular Medicine is a peer-reviewed, Open Access journal that publishes case reports in all areas of vascular medicine.
Multiple coronary artery fistulae arising from all 3 major coronary arteries emptying into the LV are extremely rare. There are case reports and small series that have demonstrated inducible ischemia on myocardial nuclear studies.1 There are no reports that demonstrate the subendocardial nature of inducible ischemia as observed in this case by cardiovascular magnetic resonance imaging. It is commonly believed that the perfusion defect corresponds to the region of myocardium that is bypassed by the intramyocardial fistulae. Adenosine-induced hyperemia decreases the diastolic perfusion gradient, increasing shunting by the fistulae and hence causing a coronary steal phenomenon. This steal phenomenon explains the clinical finding that sublingual nitrates exacerbate ischemic symptoms. In the present case, symptoms were abolished by β-blockade.. ...

BACKGROUND AND PURPOSE Congenital coronary artery fistula (CAF) is an uncommon anomaly. It can become symptomatic, associated with significant morbidity and mortality. We report our experience in percutaneous treatment of CAF. METHODS AND RESULTS Four patients with five CAFs were treated. All were symptomatic at admission. Four fistulas rose from the left anterior descending coronary artery. The fifth originated from the right coronary sinus. All drained into the pulmonary artery. Percutaneous treatment was performed using microcoils in two cases and Hydrocoils in the last two patients (three fistulas). A complete occlusion was achieved in all. There was no complication related with the procedure, and all were asymptomatic at the follow-up. CONCLUSIONS Transcatheter closure of CAFs with microcoils/Hydrocoils is feasible and safe in the anatomically suitable vessels, with low rates of complications. Percutaneous treatment with microcoils/Hydrocoils is a valid option in symptomatic patients.

Continued experience confirms the suitability of electrovitreotomy for dividing pathogenically taut proliferative and non-proliferative vitreous forms with a minimum of bleeding, and an inability to cut vitreous of ordinary consistency and tension. It differs directly with electrovitrectomy in these regards. To use effectively with a minimum of complications it is mandatory to have a vitrectomy capability immediately at hand and to respect a wide variety of interrelated factors that include: current density, electrical resistance of tissues, duration of electrical action: dimension, insulation, and configuration of the electrode: configuration, tension, location, and morphological content of dissectable structures. Mobile and dispersed blood in the liquid of the retrovitreal space often surrounds cuttable vitreous lesions. Frequently rest causes it to sediment and improves viewing sufficiently to permit effective electrovitreotomy without vitrectomy. ...

We report an interesting case of a 66-year-old man with acute myocardial infarction (AMI) with bilateral coronary ostial stenosis cardiovascular syphilis complicated by aortic regurgitation (AR). A 12-lead electrocardiogram and blood tests on arrival suggested AMI, and echocardiography showed moderate AR. Emergency coronary angiography showed bilateral coronary ostial stenosis. The patient underwent emergency surgical treatment, coronary artery bypass grafting, and aortic valve replacement with a bioprosthetic valve. On arrival, rapid plasma reagin and Treponema pallidum hemagglutination tests were 172.2- and 1187.5-fold, respectively. These results suggested cardiovascular syphilis, which was confirmed by pathological findings. The postoperative course was uneventful and the patient was transferred to another hospital on postoperative day 25. This patient received intravenous penicillin for 2 weeks and subsequently oral amoxicillin. When both AR and coronary ostial stenosis are found, it is necessary
AIM. To assess the functionality of congenital coronary artery fistulas (CAFs) using adenosine stress N-13-ammonia positron emission tomography computed tomography (PET-CT).. METHODS. Congenital CAFs were incidentally detected during coronary angiography (CAG) procedures in 11 adult patients (six males and five females) with a mean age of 64.3 years (range 41-81). Patients were collected from three institutes in the Netherlands. The characteristics of the fistulas (origin, pathway and termination), multiplicity of the origins and pathways of the fistulous vessels were assessed by CAG. Five patients underwent adenosine pharmacologic stress N-13-ammonia PET-CT to assess myocardial perfusion and the functional behavior of the fistula.. RESULTS. Eleven patients with 12 CAFs, 10 unilateral and one bilateral, originating from the left anterior descending coronary artery (n = 8), right coronary artery (n = 2) and circumflex (n = 2). All fistulas were of the vascular type, terminating into either the ...
Roughly 10% to 32% of the population has a fetal origin PCA supplying their parieto-occipital lobes in which the P1 segment is hypoplastic and the PCA is supplied primarily by a larger diameter homolateral posterior communicating artery [5, 10]. Other potentially persistent primitive carotid basilar anastomoses include the primitive trigeminal artery, the primitive acoustic (otic) artery, the primitive hypoglossal artery, and the primitive proatlantic artery. The fetal origin PCA anatomic variant provides a potential conduit for emboli from ipsilateral ICA disease [6-9]. To the best of our knowledge, artery-to-artery embolism from cervical ICA pseudoaneurysm to fetal PCA has not been previously reported. Pseudoaneurysm usually develops as a result of trauma, with rupture of the affected artery through the intima and media into the subadventitial plane. The resulting tear is contained by the adventitia forming a pseudoaneurysm. Unlike true aneurysms, pseudoaneurysms do not involve dilatation of ...

TY - JOUR. T1 - Accuracy of cross-sectional echocardiography in diagnosis of aortopulmonary window. AU - Balaji, Seshadri. AU - Burch, Michael. AU - Sullivan, Ian D.. PY - 1991/3/15. Y1 - 1991/3/15. N2 - The first echocardiographic descriptions of the aortopulmonary window (APW) were case reports.1,2 These observations were extended by Smallhorn et al,3 who described appearances of an isolated APW in 4 infants and compared these with appearances in 14 patients with a common arterial trunk and in 6 with a single pulmonary artery originating at the ascending aorta. In these reports,1-3 diagnosis was also established by invasive investigation and did not include any patient who had APW with associated cardiac abnormalities. The publication of case reports as late as 1988 suggests that the echocardiographic diagnosis of even an isolated APW is not always straightforward,4 perhaps because the lesion may be confused with other structural abnormalities.5 There have been no reports of the accuracy of ...

The large-sized PHA originating from the cervical internal carotid artery passed through the hypoglossal canal together with the hypoglossal nerve and reached the posterior cranial fossa to anastomose the basilar artery. In addition, the ipsilateral vertebral artery and bilateral posterior communicating arteries were hypoplastic. Here, we discuss the developmental mechanisms underlying the formation of the PHA and the spectrum of diseases related ...
