Results:Among 18 cases of coronary artery fine branch fistula, 7 happened in right coronary artery (38.9%), 11 in left coronary artery (61.1%). Among the 11 cases in left coronary artery,5 happened in descending anterior branch, 5 occurred in left circumflex branch, 1 arised from both left anterior branch and left circumflex branch. Among the 18 cases, there are 10 cases of coronary-to-pulmonary artery fistula (55.6%), 5 cases of fistula draining into right atrium (27.8%), 2 cases of fistula draining into left atrium (11.1%) and 1 draining into right ventricle (5.6%). Interventional treatment was successful in 7 patients. During the 12 months’ follow-up, there was no cardiovascular events. Conclusion:Selective coronary angiography is the first choice for diagnosing the coronary artery fine branch fistula. In respect of therapy, besides of surgical treatment, intervention is still a rather good measure presently.展开更多

One of the common ...Background Transcatheter bronchial artery embolization （BAE） is widely used for the treatment of hemoptysis and the immediate success rate is high, but there are still some hemorrhage recurrences. One of the common reasons for failure of BAE is collateral branches as blood supply. The inferior phrenic artery （IPA） is one of the most common collateral branches that is scarcely reported. Our purpose was to observe manifestations of IPA supplying to hemoptysis and evaluate the efficacy and safety of IPA embolization. Methods Angiography during interventional treatment of 178 hemoptysis patients in the past 7 years confirmed that IPA hemorrhage resulted in hemoptysis in 25 patients （26-67 years old） who had： lung cancer （11 patients）, bronchiectasis （11 patients）, chronic lung inflammation （2 patients）, and pulmonary tuberculosis （1 patient）. Among the 25 patients, 7 patients had twice interventional operations within one week and 6 patients still experienced intraoperative hemoptysis after conventional embolization of the bronchial artery, the internal thoracic artery, and the intercostal artery, then had the second interventional operation immediately. The total number of cases were 191. Selective embolization of the IPA was performed using polyvinyl alcohol microspheres, gelatin sponge particles, and microcoil. The safety and clinical significance of IPA embolization were evaluated. The Pearson X2 test and Fisher＇s exact probability test were used in this study. Results Selective IPA angiography showed increased diameter of the IPA, disorganization of the branches, and varying degrees of angiogenesis. In 11 cases, contrast material was seen in vessels supplying the tumor and in the tumor. In 9 cases, contrast material had leaked into the area supplied by the IPA; in 8 cases, non-specific flake-like deposits of contrast material were seen; and in 14 cases, abnormal communication or shunt was visualized. Lesions were closely related to the pleura in 25 patients. Fifteen lesions were close to the diaphragmatic pleura, seven close to the mediastinal pleura, and three close to the lateral pleura of the lower lung. Eleven cases had inferior thoracic pleural thickening and adhesions. The IPA was embolized in 25 cases, and the success rate of hemostasis was 100%. The IPA was not embolized in the other 166 cases, and the success rate of hemostasis was 92.17 %. In the 25 cases with IPA embolization, the involvement of the IPA in the blood supply of the hemoptysis was correlated with the duration of the disease （P=0.0344）. The involvement of IPA in the blood supply of the hemoptysis was not correlated with the characteristic of the lung lesions （benign or malignant） （P=1.0000）. Duration of follow-up was 8 months to 5 years. Hemoptysis recurred in four patients 1,2, 3, and 6 months after interventional operation, respectively, and was controlled by conservative treatment. Twenty-one patients had no recurrence of hemoptysis. Conclusions Bleeding from the IPA can result in hemoptysis and failure of BAE in the treatment of hemoptysis. If IPA hemorrhage contributes to hemoptysis, supplementary IPA embolization may be a safe and effective treatment.展开更多

METHODS: Sixteen patients with hypervascular vertebral tumors underwent transarterial embolization before surgery. The lesions were located between the middle cervical and lower lumbar spine. Forty-one arteries were embolized with permanent particles injected through a microcatheter, including polyvinyl alcohol (PVA) particles (150 - 500 micro m) in 25 arteries and Dextran particles (150 - 350 micro m) in 16. Of these, 31 had pieces of gelatin sponge added for proximal pedicled embolization. The criteria for judging the effectiveness of embolization were completeness of tumor removal and estimated blood loss during surgery. RESULTS: The particles were injected into the tumor feeders through superselection in 17 arteries or flow control in 24. Tumor embolization was defined as 'total' in five patients, 'nearly total' in eight, 'subtotal' in two, and 'partial' in another. There were no symptomatic complications associated with embolization. Tumors were entirely removed in all patients. The average estimated blood loss during surgery was 1510 ml (range of 200 - 6000 ml) for all 16 patients. CONCLUSION: Preoperative embolization of hypervascular vertebral tumors is safe and effective. It can make complete resection of a tumor possible and can make a previously unresectable tumor resectable. Superselection or flow control is necessary to achieve effective devascularization and to avoid complications.展开更多

Aim: The aim of this study is to present a case of a congenital coronary artery fistula presented with coronary steal and describe this phenomenon. Methods: A systematic search was conducted to explore the relationship between the coronary steal phenomenon and coronary artery diseases using the PubMed database. Case Presentation: A seven-month-old female patient, was admitted to the hospital presenting diaphoresis on feeding and failure to thrive. Physical examination denotes continuous murmur in the fourth intercostal space left parasternal border (IV/VI) crescendo-decrescendo, wide and permanent unfolding of S2 (S1-A2-P2). An echocardiogram shows enlargement of right cavities, dilatation of the left coronary artery, circumflex artery connected to the right ventricle, and pulmonary artery systolic pressure of 45 mmHg. Tomography angiography demonstrated dilatation of the circumflex artery and a tortuous trajectory towards the posterior wall of the right ventricle, suggesting a coronary fistula. Results: The findings were corroborated by catheterization and a vascular plug (Amplatzer AVP II) was successfully placed. During follow-up complete obliteration was observed, with adequate weight gain and no associated symptoms. Conclusion: This case illustrates a distinctive clinical manifestation of congenital coronary artery fistula associated with the coronary steal phenomenon, establishing a new paradigm for the early diagnosis and management of this condition in the pediatric population.展开更多
