Is Radiofrequency Ablation Better than Venous Stripping for Management of Chronic Venous Insufficiency?

Chronic venous insufficiency (CVI) is a disease of the vein due to valve dysfunction, venous obstruction, or both. This results in increased vein pressure and related to disruption in the vein system.

Neonatal repair of total anomalous pulmonary venous connection accompanied by unilateral lung agenesis and Goldenhar syndrome: a case report

Background Total anomalous pulmonary venous connection accompanied by unilateral lung agenesis and Goldenhar syndrome is extremely rare. Case presentation We present a case of total anomalous pulmonary venous connection accompanied by unilateral lung agenesis and Goldenhar syndrome in a patient who was diagnosed based on transthoracic echocardiography and computed tomography. We observed complete absence of the lung, the bronchial tree, and vascular structures on the right side, with abnormal drainage of the left pulmonary veins into the innominate vein. The patient showed clear clinical evidence of pulmonary venous obstruction and underwent surgery 3 days after birth. The pulmonary venous chamber containing the vertical vein was anastomosed to the left atrium using 7–0 PDS running sutures via a median sternotomy. Echocardiography and computed tomography performed 1 year postoperatively revealed no pulmonary venous obstruction. Conclusion We report a rare case of total anomalous pulmonary venous connection accompanied by unilateral lung agenesis and Goldenhar syndrome, which was successfully repaired 3 days after birth. A median sternotomy is a safe and effective approach for surgical repair of congenital heart disease with unilateral lung agenesis. Repair of the supra cardiac total anomalous pulmonary connection using the vertical vein is feasible in patients with a small pulmonary venous chamber.

Brachio-azygos transthoracic arteriovenous grafts for hemodialysis patients with bilateral central venous obstruction: A small case series

Background: It is difficult to find a reliable outflow vein for vascular access in hemodialysis patients with bilateral central venous obstruction. The lower extremity veins are currently used as the most common alternative veins to make a new vascular access. However, in patients not amenable to make lower extremity access, intrathoracic vein should be considered as an outflow vein, but there are limitations in its use due to postoperative complications. Methods: We introduce a series of cases that underwent arteriovenous graft operation using an intrathoracic vein, the azygos arch, as an outflow vein. Brachio-azygos transthoracic arteriovenous graft is a surgical procedure that anastomoses the azygos arch and the brachial artery with 7 mm ringed polytetrafluoroethylene graft via lateral thoracotomy without median sternotomy. Results: The chest tubes of the patients were removed on the third postoperative day and they discharged within a week. About 1 month later, hemodialysis was initiated through the BATAVG, and it has been used without access dysfunction. Conclusion: Brachio-azygos transthoracic arteriovenous grafts were performed using the azygos arches without major complications. The azygos arch can be a good alternative outflow vein to make a new vascular access for hemodialysis patients with bilateral central venous obstruction.

Risk Factors for Lead-Related Venous Obstruction: A Study of 2909 Candidates for Lead Extraction

Background: our knowledge of lead-related venous stenosis/occlusion (LRVSO) remains limited and there is still controversy regarding the risk factors for LRVSO. Venography is mandatory before transvenous lead extraction (TLE). Methods: we performed a retrospective analysis of venograms in 2909 patients (39.43% females, average age 66.90 years) who underwent TLE between 2008 and 2021 at high-volume centers. Results: the severity of LRVSO was likely to be dependent on the number of leads in the system (OR = 1.345; p = 0.003), the number of abandoned leads (OR = 1.965; p < 0.001), the presence of coronary sinus leads (OR = 1.184; p = 0.056), male gender (OR = 1.349; p = 0.003) and patient age at first CIED implantation (OR = 1.008; p = 0.021). The presence of permanent atrial fibrillation (OR = 0.666; p < 0.001) and right ventricular diastolic diameter (OR = 0.978; p = 0.006) showed an inverse correlation with the degree of LRVSO. The combined three-model multivariate analysis provided better prediction of LRSVO using the above-mentioned factors than the CHA2DS2-VASc score. Conclusions: the severity of LRVSO is probably dependent on the mechanical impact of the implanted/abandoned leads on the vein wall, therefore the study has demonstrated the central role of system-/procedure-related risk factors. The thrombotic mechanism may be less important, especially long after implantation, and for this reason the combined prediction model for LRVSO in this study was more effective than the CHA2DS2-VASc score.

Budd chiari syndrome: A case report on a rare disorder

Budd Chiari syndrome (BCS) is a rare disease that threatens life due to a hepatic vein blood flow obstruction. As per the literature, thrombosis is a significant factor for hepatic venous obstruction. It can treat BCS based on the severity of the patient’s condition by three methods like hepatic vein angioplasty, interventional radiology stenting with direct intrahepatic portosystemic shunt, or liver transplantation. We describe the case of a 34-years-old female patient who presented with abdominal distension and generalized weakness with a history of BCS. A cooperative collaboration of hepatologists and interventional radiologists helps in effectively treating the syndrome.
