Background/Objectives: After pneumonectomy, the right ventricular stroke volume is pumped into pulmonary vessels whose volume has been reduced by approximately 50%. To sustain conditions for pulmonary flow, the flow reserve is increased in the remaining lung, which is conducive to the development of pulmonary hypertension symptoms. This study sought to examine pulmonary flow in one lung and the size of the right atrium (RA), right ventricle (RV) and pulmonary artery (PA) in patients who had undergone pneumonectomy and to establish the influence of time since pneumonectomy on these parameters, as well as their potential mutual dependencies. Methods: The retrospective analysis included 34 patients who had undergone pneumonectomy. Pulmonary flow was measured by means of perfusion scintigraphy. The diameters of the RA, RV and PA were evaluated based on computed tomography with contrast. Results: We observed complete or near-complete utilization of flow reserve in 38.2% (13/34) of patients, enlarged transversal and longitudinal dimensions of the RA in 17.6% (6/34) and 32.3% (11/34) of patients, respectively, and enlarged transversal and longitudinal dimension of the RV in 67.6% (23/34) and 44.1% (15/34) of patients, respectively. Dilatation of the PA was discovered in 23.5% (8/34) to 26.5% (9/34) of patients, as well as the presence of an extensive complex of radiographic features of pulmonary hypertension (PH) syndrome in 23.5% (8/34) of cases. Conclusions: Radiological features of PH were present in a significant number of patients. These features developed at varying rates but were present in all patients followed >10 years after the procedure.

Subclavian artery pseudoaneurysms are rare but potentially life-threatening vascular injuries frequently associated with trauma such as clavicle fractures. In this paper we describe the case of a 49-year-old male who developed a post-traumatic pseudoaneurysm of the subclavian artery after a bicycle accident. The diagnosis was delayed due to non-specific symptoms and an initially missed aneurysm on computed tomography imaging. Persistent pain, swelling, and erythema in the subclavian region prompted further detailed diagnostics, which ultimately revealed the pseudoaneurysm. The patient was successfully treated with endovascular stent–graft implantation. We screened the PubMed database to identify similar cases managed exclusively through endovascular intervention. Reports of iatrogenic pseudoaneurysms and those treated with open surgery were excluded. Variables such as time to diagnosis, clinical presentation, features of pseudoaneurysms, and complications were analyzed to highlight the role of endovascular techniques as a minimally invasive and effective treatment option. These cases pose both a diagnostic and a therapeutic challenge, as early recognition of symptoms is crucial to prevent serious complications including thrombosis, neurological deficits, and even limb loss.

Neurofibromatosis type 1 (NF1) significantly increases the risk of malignant peripheral nerve sheath tumors (MPNST), a rare and aggressive malignancy for which treatment is clinically challenging. This paper presents the case of a 24-year-old male with an NF1 who developed MPNST with lung metastases. Due to the limited effectiveness of systemic therapy in the treatment of MPNST, the patient underwent radical surgical resection and radiotherapy. Pathological evaluation confirmed high-grade MPNST, and PET-CT imaging revealed further metastatic progression. The treatment results for our patient are compared with those of other patients with NF1 who also developed MPNST with lung metastases in the literature. The findings suggest the need for further research into personalized treatment strategies that may improve prognosis and overall survival in patients with NF1 and MPNST, with immunotherapy being a promising therapeutic option.

Mediastinal yolk sac tumors (YST) constitute a highly malignant subtype of primary non-seminomatous germ cell tumors, which are often locally advanced and unresectable at diagnosis. Due to their rarity and aggressiveness, there is not yet a standard optimal treatment approach. A widely employed multimodal strategy involves neoadjuvant cisplatin-based combination chemotherapy followed by consolidation surgery. Tumor infiltration into the lungs and adjacent cardiovascular structures is common, such that surgical intervention typically requires extensive resections, performed either by sternotomy or thoracotomy. For this review, we extensively searched the PubMed and Embase medical databases, identifying articles describing surgical treatment of mediastinal yolk sac tumors. The current literature provides limited details regarding the utilized surgical procedures, leaving clinicians without comprehensive guidance about the demanding nature of these resections. Here, we present a narrative description of the range of current surgical procedures. By highlighting these techniques, we provide a comprehensive overview of the current surgical landscape, thereby helping clinicians understand the potential complexities and considerations involved in managing these rare and aggressive tumors.

Background: Primary graft dysfunction (PGD) is a form of acute lung injury (ALI) that occurs within 72 h after lung transplantation (LuTx) and is the most common early complication of the procedure. PGD is diagnosed and graded based on the ratio of the partial pressure of arterial oxygen to the fraction of inspired oxygen and chest X-ray results. PGD grade 3 increases recipient mortality and the chance of chronic lung allograft dysfunction (CLAD). Method: The aim of this retrospective study was to identify new PGD risk factors. The inclusion criteria were met by 59 patients, who all received transplants at the same center between 2010 and 2018. Donor data were taken from records provided by the Polish National Registry of Transplantation and analyzed in three variants: PGD 1–3 vs. PGD 0, PGD 3 vs. PGD 0 and PGD 3 vs. PGD 0–2. Results: A multiple-factor logistic regression model was used to identify decreasing recipient age; higher donor BMI and higher donor central venous pressure (CVP) for the PGD (of the 1–3 grade) risk factor. Conclusions: Longer cold ischemia time (CIT) and higher donor CVP proved to be independent risk factors of PGD 3.

Poland syndrome (PS) is a rare congenital musculoskeletal entity occurring in approximately 1 in 30,000 newborns that manifests with variable symbrachydactyly, ipsilateral costochondral deformities, an absence of pectoral muscles, and breast underdevelopment. These have potential impacts on social, somatic, and psychological functionality, often leading affected individuals to seek expert opinions on corrective surgery. Due to phenotypic variability, strict management guidelines are lacking, with treatment decisions often based on the specialist’s personal experience rather than published evidence. Comprehensive imaging with CT and MRI with 3D reconstruction is crucial for providing a descriptive assessment of musculoskeletal defects. Management is multidisciplinary, involving thoracic, plastic, and pediatric surgeons and hand surgery specialists, as well as psychologists and developmental growth specialists. Surgery should achieve both structural and cosmetic correction to reverse the psychological and social impact and achieve patient satisfaction. We aim to provide thoracic surgeons the essential answers for sharing with affected adult individuals during consultations focusing on chest surgical correction.

A vessel port, implanted into the central venous system, is used for long-term intravenous drug administration in oncology patients. Although essential for frequent chemotherapy and other treatments, ports can lead to complications such as infection and thrombosis. This article discusses a rare but serious complication: the displacement of a catheter fragment. A 67-year-old gastric cancer patient, experienced malignant recurrence with jaundice and bile duct infiltration post Roux-Y subtotal gastrectomy and D2 lymphadenectomy. After nine cycles of chemotherapy, a catheter fragment from the venous port detached and lodged in a branch of the pulmonary artery in segment VIII of the right lung. Thoracotomy was performed to remove the foreign body. Our aim is to report on the surgical treatment of a displaced detached catheter and to raise awareness about the potential rare complications associated with the use of vascular ports in patients undergoing chronic oncological treatment. Additionally, we screened the PubMed database for similar surgical treatment reports and compared the collected data. Venous port malfunction or non-specific patient symptoms may indicate rare complications, such as port component detachment, necessitating a multidisciplinary approach for prompt diagnosis and management in oncological patients.

Primary pulmonary lymphoma is a rare neoplasm characterized by the proliferation of lymphoid tissue affecting the lungs. The most common subtype is marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). Rarely, a MALT lymphoma transforms into a diffuse large B-cell lymphoma (DLBCL). Treatment options include chemotherapy, radiotherapy, immunotherapy, and surgery. Here, we describe a patient with a primary pulmonary MALT lymphoma transforming into DLBCL. The purpose of this case report is to raise awareness of the relevant clinical and imaging features and to emphasize the need for a multidisciplinary approach to optimal management. In addition, we screened the PubMed and Embase databases for similar reports with a confirmed presence of transforming lymphoma within the lungs.

Introduction: A minimally invasive approach in the diagnosis of peripheral pulmonary lesions may pose a challenge for thoracic surgeons when selecting the most appropriate technique. Electromagnetic navigation bronchoscopy (ENB) is an innovative technique used in the diagnosis of lung tumors. Aim: Evaluation of the merits of ENB in patient manifesting undiagnosed pulmonary and mediastinal lesions, while concurrently investigating its influence on the determination of the ultimate therapeutic strategy. Case study: The 73-year-old male patient with a suspicious lung mass was admitted to the hospital for diagnosis and subsequent treatment. The patient underwent an invasive diagnosis of lung and mediastinum using ENB with cryobiopsy. The histopathological examination revealed adenocarcinoma and lymphoma cells, ultimately guiding the initiation of appropriate therapeutic measures. Results and Discussion: Among the available methods, those with the highest diagnostic yield and safety should be chosen. Precise diagnosis of pulmonary lesions holds paramount importance for guiding appropriate treatment in cases of suspected malignancy. Conclusions: ENB with cryobiopsy proves effective diagnosis in case of peripheral lesions that are difficult to access for classical techniques.

Situs inversus totalis (SIT) is a congenital anomaly that involves the mirror rearrangement of the thoracic and abdominal internal organs. In this paper, we report a 56-year-old male patient with previously confirmed SIT, who was admitted to the hospital for the diagnosis and surgical treatment of non-small-cell lung cancer, located in the sixth right pulmonary segment. The patient underwent segmentectomy with mediastinal and hilar lymphadenectomy. Furthermore, we screened the PubMed and Embase databases for reports of the surgical treatment of patients with SIT and lung cancer. Articles describing inoperable and disseminated disease, as well as patients qualified for palliative treatment, were not included. Ultimately, we compared 21 articles (including the one described here). Data about the clinical condition, tumor characteristics, treatment, and histopathological examination were extracted and summarized.
