Pulmonary arteriovenous malformations (PAVM) are abnormal communication of a branch of the pulmonary artery and pulmonary vein circumventing the intervening pulmonary capillaries. This results in a right-to-left (R-L) shunt and its related manifestations, which include hampered gas exchange leading to hypoxaemia, dyspnoea, paradoxical emboli leading to stroke, cerebral abscess, myocardial infarction and pulmonary haemorrhage due to rupture of the PAVM. Endovascular transcatheter embolization of the feeding vessels with coils or occlusion devices is the current standard care of treatment and preferred treatment modality. The articles aim to provide insights into the current trends in diagnosis, the current recommendations, approach and management options for patients with PAVM.
Anomalous origin of left anterior descending artery (LAD) from pulmonary artery (PA) with dual LAD from left sinus is an extremely rare coronary anomaly. The diagnostic challenge lies in differentiating this from a coronary cameral fistula. Surgical reimplantation of the anomalous LAD is recommended to prevent risk of myocardial ischaemia and ventricular arrhythmias.
Background Postpancreatectomy hemorrhage (PPH) and Hemosuccus Pancreaticus (HP) may present with slow but significant intraluminal bleed which may not be evident on imaging. We evaluated the efficacy of empirical segmental-angioembolization of splenic artery in intraluminal PPH and HP.
Result This is a cross-sectional study done by analyzing all consecutive patients with PPH and HP who underwent empirical coil embolization of splenic artery. There were total of 137 pancreaticoduodenectomies (PD), 68 distal pancreatectomies (DP), 11 patients with median pancreatectomies (MP) and 134 admissions for acute pancreatitis and exacerbation of chronic pancreatitis during the study period. Eleven (5.1%) patients had PPH, of which two were managed surgically. Among nine patients, 4/9 (44.4%) with pseudoaneurysm on computed tomography angiography (CTA) were excluded. Among pancreatitis, 7 (5.2%) had HP, and 5/7 (71.4%) patients with pseudoaneurysm on CTA were excluded. Hence, seven patients, PPH—5 and HP—2, were included. Both HP patients were managed successfully with empirical segmental coil embolization of splenic artery. Among PPH, one patient required laparotomy for failed embolization. Overall, 6/7 (85.7%) had successful coil embolization. No reintervention, continued bleed, or blood transfusions were required postprocedure, and no splenic infarct or abscess was seen in any of the seven patients postembolization. The 72-hour rebleed rate was 1/7 (14.3%), which was managed surgically.
Conclusion Empirical segmental coil embolization of splenic artery in intraluminal pancreatic bleed holds promise as a salvage life-saving procedure even when no blush or pseudoaneurysm is evident.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
