For suitable clinical cases, pulmonary segmentectomy constitutes the gold standard surgical intervention. However, locating the intersegmental planes, found both on the surface of the pleura and within the lung's internal structure, is still a formidable obstacle. Employing transbronchial iron sucrose injection, a novel intraoperative method for distinguishing intersegmental lung planes was created (ClinicalTrials.gov). The implications of the NCT03516500 clinical trial are noteworthy and require further investigation.
To ascertain the porcine lung's intersegmental plane, we initially injected iron sucrose into the bronchi. A prospective evaluation of the technique's safety and feasibility was carried out in 20 patients undergoing anatomic segmentectomy. To target pulmonary segments, iron sucrose was delivered via the bronchus, and then the intersegmental planes were separated using electrocautery or a stapler.
Iron sucrose injections, centrally, had a median volume of 90mL (ranging from 70mL to 120mL), and the median time it took for intersegmental plane demarcation, following injection, was 8 minutes (ranging from 3 minutes to 25 minutes). The intersegmental plane was accurately and comprehensively identified in 17 cases (85% of total observations). read more Three cases exhibited an inability to identify the intersegmental plane. All patients escaped complications from iron sucrose injections, as well as those of Clavien-Dindo grade 3 or higher.
A simple, safe, and viable approach for determining the intersegmental plane involves transbronchial iron sucrose injection (NCT03516500).
Transbronchial injection of iron sucrose is a simple, safe, and practical means of determining the intersegmental plane, a procedure supported by NCT03516500.

The prospect of lung transplantation for infants and young children is often complicated by the challenges that frequently hinder successful extracorporeal membrane oxygenation bridging to transplantation. Instability in neck cannulas frequently requires intubation, mechanical ventilation, and muscle relaxants, making the individual less suitable for a transplant. Five pediatric patients were successfully transitioned to lung transplantation utilizing Berlin Heart EXCOR cannulas (Berlin Heart, Inc.) for both venoarterial and venovenous central cannulation.
Our single-center, retrospective analysis focused on central extracorporeal membrane oxygenation cannulation procedures, employed as a bridge to lung transplantations at Texas Children's Hospital, occurring between 2019 and 2021.
Six patients, comprising two with pulmonary veno-occlusive disease (a 15-month-old and 8-month-old male), one each with ABCA3 mutation (a 2-month-old female), surfactant protein B deficiency (a 2-month-old female), pulmonary arterial hypertension secondary to D-transposition of the great arteries repaired neonatally (a 13-year-old male), and cystic fibrosis with end-stage lung disease, received extracorporeal membrane oxygenation support for a median period of 563 days while awaiting transplantation. Upon the initiation of extracorporeal membrane oxygenation, all patients were extubated and engaged in comprehensive rehabilitation activities up until their transplantation procedures. No complications were encountered as a result of central cannulation and the utilization of Berlin Heart EXCOR cannulas. Fungal mediastinitis and osteomyelitis, complications arising from cystic fibrosis, resulted in the patient's withdrawal from mechanical assistance and subsequent death.
Berlin Heart EXCOR cannulas, centrally cannulated, offer a novel solution for infants and young children, facilitating extubation, rehabilitation, and bridge-to-lung-transplant procedures, by overcoming cannula instability.
Novel central cannulation with Berlin Heart EXCOR cannulas eliminates cannula instability issues in infants and young children, enabling extubation, rehabilitation, and serving as a bridge to lung transplantation.

Locating nonpalpable pulmonary nodules during thoracoscopic wedge resection presents a considerable technical difficulty. Preoperative image-guided localization procedures are invariably time-consuming, costly, inherently risky, and necessitate access to advanced facilities and the expertise of well-trained operators. This study examined a budget-friendly approach for creating a well-matched interface between virtual and physical environments, critically important for accurate intraoperative localization.

For rapid and straightforward deployment, percutaneous pulmonary artery cannulas, used as inflow to support left ventricular venting or outflow for right ventricular mechanical circulatory support, rely on the guidance of transesophageal and fluoroscopic imaging techniques.
A critical analysis of our institutional and technical experience with all right atrium to pulmonary artery cannulations was undertaken.
Based on the provided critique, six cannulation strategies from right atrium to pulmonary artery are delineated. Right ventricular assist, in its total and partial forms, and left ventricular venting comprise their classifications. For supporting the right ventricle, a single-limb cannula or a dual-lumen cannula is an applicable option.
Percutaneous cannulation presents a possible advantage in right ventricular assist device deployments when faced with instances of isolated right ventricular failure. In contrast, the cannulation of the pulmonary artery serves a function of left ventricular decompression, directing drainage to either a cardiopulmonary bypass apparatus or an extracorporeal membrane oxygenation circuit. The technical aspects of cannulation, the process of selecting suitable patients, and the management of patients in these clinical circumstances are all meticulously examined in this article, making it a dependable reference.
For right ventricular assist device implementation, percutaneous cannulation may be advantageous in circumstances of isolated right ventricular failure. Conversely, utilizing a pulmonary artery cannula provides a pathway for draining left ventricular blood, redirecting it to a cardiopulmonary bypass or extracorporeal membrane oxygenation apparatus. This article provides a framework for understanding the technical intricacies of cannulation, the crucial decisions surrounding patient selection, and the subsequent management of patients within these clinical situations.
