Acquired pulmonary artery stenosis which is secondary to tuberculosis is so rare that only a few scattered cases have been reported. We report one case of pulmonary stenosis caused by pulmonary tuberculosis.l A 50 year old man who gradually developed dyspnea was diagnosed as bilateral pulmonary stenosis, he underwent bypass surgery between the main diagnosed as bilateral pulmonary stenosis. he underwent bypass surgery between the main pulmonary artery and the right pulomonary artery with a 13mm Gortex ringed straight graft. The left pulmonary artery was too small to restore the perfusion. The patient was discharged on the 33rd day after the operation. Acquired pulmonary stenosis could be treated successfully with one-side pulmonary arery reconstruction.

Pulmonary artery sarcoma (PAS) is a rare and fatal disease that often mimics chronic thromboembolic pulmonary hypertension (CTEPH); therefore, diagnosis of PAS is often delayed. Herein, a healthy 74-year-old man was presented with a 4-month history of dyspnea. Chest computed tomography showed wall thickening and stenosis in the main pulmonary artery as well as in both proximal pulmonary arteries. In order to differentiate between unusual CTEPH, vasculitis, and PAS, we performed right heart catheterization and pulmonary angiography. The mean pulmonary arterial pressure was 21 mmHg, and there was severe pulmonary artery stenosis. Thrombi on the pulmonary arterial wall lesions were observed in intravascular ultrasound and optical coherence tomography. Furthermore, the patient had a history of deep vein thrombosis. Therefore, we diagnosed unusual CTEPH. After 6 months of rivaroxaban anticoagulation therapy, a chest X-ray revealed a left lower lobe lung mass, and a positron emission tomography later showed hypermetabolic lesions in the main pulmonary artery wall, in both pulmonary arteries walls, in the lung parenchyma, and in the bones. A biopsy of the right proximal humerus lesion revealed undifferentiated intimal sarcoma. Pulmonary sarcoma is rare, but should be considered when differentially diagnosing main pulmonary artery wall thickening and stenosis. A positron emission tomography may aid in this diagnosis.

Pulmonary vein wedge angiography was applied to two patients of 2 years old TOF with PFO. Left pulmonary artery was not visualized by standard right ventriculogram and catheter was not entered into main pulmonary artery. Through PFO and left atrium, pulmonary vein wedge angiography at left lower pulmonary vein was done. The ipsilateral pulmonary artery & its trees in both cases and the contralateral pulmonary artery in one case were well visualized. Dangerous complication, such as massive bronchoconstriction due to extravasation of contrast material into the bronchus, was not developed. Mild coughing was occurred, but well tolerable in both cases. We recommended a dose of 0.8 mL/Kg of contrast material at a rate of 2 to 3 mL/sec and 1 to 2 mL/Kg of flush solution at the same rate by the hand, and routine use of pulmonary vein wedge angiography in cyanotic patients whose pulmonary artery was not visualized by the standard angiography.

A case of malignant fibrous histiocytoma [MFH] of left pulmonary artery was reported in the 27 year-old male. He was admitted because of hemoptysis for several times. Chest x-ray revealed nodular lesions in left hilar area and left upper lobe. A left thoracotomy was performed followed left upper lobectomy. The main tumor was originated from the pulmonary arterial bifurcation and proximal portion of the left pulmonary artery. By light microscopy, there were many pleomorphic giant cells, which displayed the storiform pattern. And in those area, dilated or compressed vascular channels were involved by tumor cells, suggesting origin of This tumor. Pulmonary artery angiography and chest CT revealed this tumor was originated from pulmonary artery. It would be the first reported primary malignant fibrous histiocytoma of the pulmonary artery in our country. Postoperative prognosis was uneventful, but recently he was suffered from dyspnea, that was noticed by OVD follow-up for 1 month, probably the heart failure sign due to pulmonary arterial flow obstruction.

Bilateral coronary artery-pulmonary artery fistula is very uncommon congenital heart disease which occupy small percentage of all coronary arterio-venous fistulas. We experienced a case who was 52 years old female with bilateral coronary artery-pulmonary artery fistula. She complained exertional dyspnea k angina[coronary steal syndrome]. On physical examination, any cardiac murmur was not audible. There was no 0y step-up in right heart catheterization. But selective coronary angiography revealed tortuous aberrant vessels which originated from the canal branch of the right coronary artery k the left anterior descending coronary artery. Both aberrant vessels traversed the right ventricular outflow tract, and conjoined just proximal the pulmonic annulus and drained into the main pulmonary artery. The operation was performed under the extracorporeal circulation with beating heart. The procedures were suture-ligation of the draining orifice in main pulmonary artery & the feeding vessels on the right ventricular outflow tract. Postoperatively her complaints were completely disappeared and the selective coronary angiography revealed no left-to-right shunt.

Pulmonary artery aneurysms are extremely rare conditions usually associated with congenital cardiac defects that cause increased pulmonary blood flow and pulmonary hypertension. The prognosis of pulmonary artery aneurysms is fatal due to the potential for rupture of the aneurysm and the underlying severe pulmonary hypertension. A 40-year old woman was admitted to our hospital with headache following traffic accident. On admission a continuous murmur was heard over the 2nd to 3rd intercostal space along left sternal border and a calcified cystic mass at left hilar portion was incidentally discoverd on chest reontgenogram. Cardiac catherization was diagnostic of a left to right shunt at main pulmoanry artery level and pulmonary hypertension. Pulmonary angiogram demonstrated a large aneurysm of main pulmonary artery extending into proximal left pulmonary artery. The pulmonary artery aneurysm associated with patent ductus arteriosus was diagnosed definitively and the patient was underwent resection of pulmonary artery aneurysm, closure of PDA and Dacron prosthetic graft replacement under cardiopulmonary bypass. The postoperative course was uneventful and the patient was discharged without any problem.

Background: Although the modified Blalock-Taussig shunt remains the mainstay method of palliation for augmenting pulmonary blood flow in various congenital heart diseases, the shunt must be carefully designed to achieve the best outcomes. This study investigated the effect of shunt configuration on pulmonary artery growth and growth discrepancy. Methods: Twenty patients with successful modified Blalock-Taussig shunt takedown were analyzed. Pulmonary artery and shunt characteristics were obtained using computed tomography scans. Differences in the baseline and follow-up diameter ratios and growth in the ipsilateral and contralateral arteries were calculated. The angle between the shunt and pulmonary artery, as well as the distance from the main pulmonary artery bifurcation, were measured. Correlations between pulmonary arteries and shunt configurations were analyzed. Results: The median interval time between shunt placement and takedown was 154.5 days (interquartile range, 113.25-276.25 days). Follow-up values of the ipsilateral-to-contralateral pulmonary artery diameter ratio showed no significant correlation with the shunt angle (ρ=0.429, p=0.126) or distance (ρ=0.110, p=0.645). The shunt angle and distance from the main pulmonary bifurcation showed no significant correlation (ρ=-0.373, p=0.189). Pulmonary artery growth was negatively correlated with shunt angle (ipsilateral, ρ=-0.565 and p=0.035; contralateral, ρ=-0.578 and p=0.030), but not with distance (ipsilateral, ρ=-0.065 and p=0.786; contralateral, ρ=-0.130 and p=0.586). Conclusion: Shunt configuration had no significant effect on growth imbalance. The angle and distance of the shunt showed no significant correlation with each other. A more vertical shunt was associated with significant pulmonary artery growth. We suggest a more vertical graft design for improved pulmonary artery growth.

A patient with anomalous coronary artery crossing right ventricular outflow tract in association with Tetralogy of Fallot underwent total correction. The left anterior descending coronary artery was originated from right coronary artery anterior to the pulmonary valve ring. The incision from outflow tract to pulmonary artery tunneled underneath the aberrant artery and patch graft across the pulmonary valve ring to enlarge outflow of right ventricle and stenotic pulmonary valve ring.

Primary sarcomas of the pulmonary arteries are and the clinical presentation closely resembles several more common conditions, Therefore they are seldomly diagnosed preoperatively without a pathologic esxamination of sufficient surgical specimen. Treatment of these tumors remains primarily surgical as possible and the role of the adjuvant chemotherapy and radiotherapy is not yet evident We report a case of primary sarcoma of pulmonary artery clinically suspected of carcinoid partially involving the pulmonary parechyme and the bronchus mainly in the left main pulmonary artery and the vein with left intrapericardial pneumonectomy.
