AbstractA rare case of a pulmonary arterio-venous malformation not requiring treatment is reported. An incidental peripheral right lower lobe intrapulmonary pulmonary arterio-venous malformation was identified on computed tomography. On catheter angiography, no pulmonary artery supply was identified. Systemic artery catheter arteriography identified systemic arterial supply from a conjoined inferior phrenic artery with pulmonary venous drainage to the left atrium. Due to this lung abnormality being a systemic arterial circulation to pulmonary venous circulation (left to left or circular) shunt, no treatment was indicated.

Pulmonary Artery Fistula

Systemic artery-to-pulmonary artery fistula (SA-PAF) is a rare phenomenon that can resemble a filling defect on computed tomography angiography (CTA). SA-PAF can be due to congenital or acquired etiologies and can alter the hemodynamics of the pulmonary circulation, with the most serious reported complication being hemoptysis, requiring embolization. We describe a case of an unusual SA-PAF between the right inferior phrenic artery and the right lower lobe pulmonary artery that mimicked an unprovoked pulmonary embolus (PE) on standard CTA in a patient with cardiomyopathy. This SA-PAF was interpreted on CTA as PE due to the presence of a filling defect, revealing that not all filling defects are PE. SA-PAF should always be considered when the clinical context or the imaging findings are atypical, specifically with an isolated filling defect visualized in the inferior lower lobe pulmonary artery. The false-positive PE was the result of mixing of systemic non-opacified blood with opacified pulmonary arterial blood.

AbstractCongenital venolobular or scimitar syndrome is a rare congenital cardiopulmonary anomaly consisting in a partial anomalous pulmonary venous drainage, lung hypoplasia, and anomalous systemic arterial supply to the lung. It can associate with other congenital disorders which will confer the clinical presentation and prognosis of these patients. In most of the cases, the therapeutic approach is partial, as anatomy allows only aberrant arterial embolisation. We present a 6-year-old girl with recurrent pulmonary infections, diagnosed as scimitar syndrome with double collector drainage to the inferior caval vein and left atrium, undergoing interventional catheterisation for complete correction of her disorder. The anomalous systemic artery supply was embolised and the anomalous venous drainage was occluded. The patient was asymptomatic during follow-up, which supports the interventional catheterisation approach as a valid therapeutic option in cases of scimitar syndrome with double venous drainage.

Systemic Arterial Supply

Systemic arterial supply to a segment of normal lung is rare. 1 Usually the anomalous systemic artery arises from the descending aorta, although it can arise from other sites including the coeliac axis. 1–3 Case reports documenting an anomalous artery to normal lung from the coeliac axis are few. However, in these cases the patients were being investigated for respiratory symptoms and all were under the age of 50. In our case, we describe a rare case of anomalous systemic arterial supply arising from the coeliac axis to the right lower lobe, in the absence of abnormal bronchial connection or parenchymal disease in an asymptomatic patient. The anomalous arterial supply was an incidental finding on CT. The literature suggests surgical treatment to prevent symptoms of haemoptysis or congestive cardiac failure, but it is unclear from current evidence whether this is indicated in an asymptomatic patient.

Abstract The systemic artery to pulmonary vessel fistula(SAPVF) is an uncommon vascular abnormal communication between systemic arteries (except bronchial arteries) and the lung parenchyma[1]. It can be divided into congenital and acquired causes. Congenital SAPVF is often accompanied by cardiac or pulmonary artery hypoplasia, and acquired are usually caused by pleural adhesions after pleurisy, empyema, trauma, or surgery[2].We report a case of transcatheter arterial embolization for the treatment of congenital right inferior phrenic artery to pulmonary artery fistula.

AbstractScimitar or pulmonary venolobar syndrome, a rare pulmonary anomaly, consists basically of anomalous pulmonary venous drainage of the right lung to the inferior caval vein, anomalous systemic arterial supply to the right lower lobe from the descending aorta, hypoplasia of the right lung, and dextroposed heart. We present a rare case with constellation of all these findings of scimitar syndrome, but with the aberrant pulmonary vein draining into the left atrium.

The Ideal

Anomalous systemic arterial supply to the basal segments of the left lower lobe without coexisting pulmonary artery connection is a rare anomaly. Most feel treatment is necessary; however, the ideal strategy is unclear. Treatments described include embolization, pulmonary resection, or anastomosis to the native pulmonary artery. We recently encountered an infant with this anomaly and present a literature review summarizing all recent reports. Additionally, we describe a novel surgical technique to create a tension-free anastomosis utilizing segmental aortic translocation that we employed in our patient due to a large distance between the anomalous vessel and native left pulmonary artery.

Abstract Background Ruptured pseudoaneurysms are a rare complication of gastrectomy, but when they do develop, they are often fatal. We presented herein the first report of a case of pseudoaneurysm arising from the right inferior phrenic artery (RIPA) after a laparoscopic gastrectomy. Case presentation A 61-year-old male patient underwent a laparoscopic distal gastrectomy and D1+ lymph node dissection with Roux-en-Y reconstruction for early gastric cancer. He was discharged on postoperative day (POD) 9 without any complications, such as anastomotic or pancreatic leakage. On POD 19, he was referred to the emergency room for upper abdominal pain. Enhanced abdominal computed tomography revealed a 60 × 70 mm hematoma, indicating intra-abdominal bleeding and a 10-mm pseudoaneurysm in the RIPA. Selective digital subtraction angiography confirmed the presence of a pseudoaneurysm in the RIPA, which was embolized using multiple microcoils. Thereafter, no clinical signs were observed, and the patient was discharged from the hospital 15 days after angiography without any recurrence of bleeding. We hypothesized that the cause of the pseudoaneurysm was mechanical vascular injury due to the thermal spread of the ultrasonically activated devices (USADs) during lymphatic node dissection. Conclusion Given the thermal spread of USADs, safe and appropriate lymph node dissection based on precise anatomical knowledge is crucial to preventing postoperative pseudoaneurysms.
