Project description:We present the case of an infant with total anomalous pulmonary venous connection and a branching vertical vein with multiple points of narrowing, draining the confluence into the innominate vein. The embryology and clinical relevance of this interesting anatomy is discussed.
Project description:IntroductionObstructed total anomalous pulmonary venous connection (TAPVC) is one of the commonest seen emergencies in pediatric cardiology centers.Case presentationOur case was diagnosed to have this anomaly, showing early respiratory distress resulting from severe pulmonary congestion. Palliative stenting of the obstruction was done, which helped in stabilizing the debilitated hemodynamics of the baby before surgery, thus a good surgical outcome and prognosis are expected.ConclusionThis intervention may be listed as a vital measurement in the preoperative cardiac stabilization plan for infants with obstructed TAPVC.
Project description:ObjectivesA meta-analysis was performed to investigate the risk factors for postoperative pulmonary venous obstruction (PVO) after surgical repair of total anomalous pulmonary venous connection (TAPVC).MethodsData bases including PubMed, Embase, Web of Science and Cochrane Library were searched systematically. The goal was to discuss the risk factors for postoperative PVO after TAPVC. Publications were screened by 2 authors independently for criteria inclusion, methodological quality assessment and data extraction. The Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality checklist were obtained to assess the quality of the studies. Data were pooled by the random effect model or the fixed effect model according to the heterogeneity test.ResultsA total of 16 studies (2,385 participants) were included in the meta-analysis. All included studies were retrospective studies. Six potential risk factors were pooled, 5 of which were significantly associated with postoperative PVO. Patients with preoperative PVO were more likely to suffer from postoperative PVO [odds ratio (OR)=5.27, 95% confidence interval (CI) = (2.75, 10.11), P < 0.01]. Compared with a sutureless procedure, the conventional operative procedure was associated with postoperative PVO [OR = 1.80, 95% CI=(1.20, 2.71), P < 0.01]. A mixed type TAPVC plays a critical role in postoperative PVO [OR = 3.78, 95% CI=(1.08, 13.18), P = 0.04]. Inverse variance analysis showed that longer cardiopulmonary bypass time [hazard ratio (HR)=1.01, 95% CI=(1.01, 1.02), P < 0.00001] and aortic cross-clamp time [HR = 1.01, 95% CI=(1.01, 1.02), P < 0.01] were significantly associated with postoperative PVO. Heterotaxy [OR = 1.18, 95% CI = 0.13, 10.45, P = 0.88] was not statistically significant as a risk factor for postoperative PVO.ConclusionsThis meta-analysis may provide a perspective on the risk factors for postoperative PVO after TAPVC, thus leading to more studies predicting postoperative PVO after TAPVC with our findings.
Project description:BACKGROUND:Massive hemoptysis is a life-threatening condition. Massive hemoptysis caused by pulmonary vein stenosis (PVS) after radiofrequency catheter ablation for atrial fibrillation (AF) is rare. However, bilateral lung hemorrhage following bilateral PVS is extremely rare. CASE PRESENTATION:We herein describe a 62-year-old man with refractory massive hemoptysis after radiofrequency catheter ablation for AF, which was successfully controlled by surgical lobectomy and endovascular bilateral PV stenting. The hemorrhage was derived from the bilateral lungs following PV obstruction and bilateral PVS, which was definitively diagnosed by bronchoscopic examination. The patient had no recurrence of hemoptysis during a follow-up period of 30 months, and the PV stents had not narrowed as shown by computed tomography 30 months after stent placement. CONCLUSIONS:Massive hemoptysis can be caused by bilateral PVS after radiofrequency catheter ablation for AF, and hemorrhage from the bilateral lungs in such patients is extremely rare. Nevertheless, cardiologists, interventional radiologists, and pulmonologists should consider the potential for massive hemoptysis caused by PVS.
Project description:Venous thromboembolism has been associated with high morbidity and mortality, with a cost burden for the U.S. health care system owing to secondary complications such as pulmonary embolism and post-thrombotic syndrome. The current standard of therapy for acute deep vein thrombosis (DVT) is anticoagulation. For patients with venous outflow obstruction of the iliac vein system, several minimally invasive recanalization techniques are now available. In the present report, we have described a case of bilateral internal iliac DVT that had progressed to right-sided iliofemoral DVT in a young athletic adult, in the absence of anatomic abnormalities, that was treated with thrombolysis-free mechanical thrombectomy.
