Unplanned Perioperative Reoperation Following Pulmonary Resection in Lung Cancer Patients: A Report of a Single-Center Experience.

Pulmonary resection is an important part of comprehensive treatment of lung cancer. Despite the progress in recent thoracic surgery, reoperation is occasionally inevitable for managing severe perioperative complications. This study aimed to investigate the incidence and causes of perioperative reoperation in lung cancer patients. We retrospectively collected patients who underwent reoperation following pulmonary resection from January 2010 to February 2021 in China-Japan Friendship Hospital. Among the 5032 lung cancer patients who received primary pulmonary resection in our institute, 37 patients underwent perioperative reoperation with the rate being 0.74%. Lobectomy was the most frequently executed procedure (56.8%). The mean duration of the primary surgery was 143.6 ± 65.1 min. About half of the cases received secondary surgery within 24 h of the primary surgery, whereas only one case underwent secondary surgery 30 days after the primary surgery (due to chylous leakage). The major causes of the reoperation were bleeding (73.0%), chylous leakage (13.5%), lobar torsion (5.4%), air leakage (2.7%), atelectasis (2.9%), and cardiac herniation (2.7%). The most prevalent reasons for unplanned reoperation following pulmonary resection in lung cancer patients include bleeding, chylous leakage, and lobar torsion. The strict control of the surgical indications and standardization of surgical procedures are fundamental to reduce unplanned secondary operations after pulmonary resections. Timely identification of the need to secondary surgery is also important to ensure patients' safety.

Cardiac herniation post left upper lobectomy and thymectomy: a case report

BackgroundCardiac herniation occurs when there is a residual pericardial defect post thoracic surgery and is recognised as a rare but fatal complication. It confers a high mortality and requires immediate surgical correction upon recognition. We present a case of cardiac herniation occurring post thymectomy and left upper lobectomy.Case presentationInitial presentation: A 48-year-old male, hypertensive smoker presented with progressive breathlessness and was found to have a left upper zone mass confirmed on CT biopsy as carcinoid of unclear origin. PET-CT revealed avidity in a left anterior mediastinal area, left upper lobe (LUL) lung mass, mediastinal lymph nodes, and a right thymic satellite nodule. Intraoperatively: Access via left thoracotomy and sternotomy. The LUL tumour involved the left thymic lobe (LTL), left superior pulmonary vein (LSPV), left phrenic nerve and intervening mediastinal fat and pericardium, which were resected en-masse. The satellite nodule in the right thymic lobe (RTL) was adjacent to the junction between the left innominate vein and superior vena cava (SVC). The pericardium was resected from the SVC to the left atrial appendage. Clinical deterioration: Initially the patient was doing well clinically on day 1, however there was sudden bradycardia, hypotension, clamminess, and oligoanuria, with raised central venous pressures and troponins. ECG: no capture in leads V1-2, but positive deflections seen on posterior leads. Echo: no acoustic windows, but good windows seen posteriorly. CXR: left mediastinal shift. Redo operation: After initial resuscitation and stabilisation on the intensive care unit, on day 2 a redo-sternotomy revealed cardiac herniation into the left thoracic cavity with the left ventricular apex pointing towards the spine, and inferior caval kinking. After reduction and repair of the pericardial defect with a fenestrated GoreTex patch, the patient recovered well with complete resolution of the ECG and CXR.ConclusionCardiac herniation can even occur following sub-pneumonectomy lung resections and should be considered as a differential when faced with a sudden clinical deterioration, warranting early surgical correction.

Late presentation of traumatic tricuspid valve chordal rupture and pericardial rupture with cardiac herniation: a case report

BackgroundAlthough chest trauma happens very often, accompanying tricuspid valve injuries occur rarely and may be manifested by scarce symptoms and signs. Pericardial rupture with cardiac herniation is even a bigger rarity. Transthoracic echocardiography plays a key role in the diagnosis of valve injuries but is of limited value in cardiac herniation.Case presentationWe present the case of 58-year-old man who experienced severe chest trauma in a car accident. Symptoms of right heart failure occurred 10 years after the injury, due to the loss of tricuspid leaflet support caused by the rupture of tendinous chords with significant tricuspid regurgitation. Intraoperatively, old posttraumatic pericardial rupture into left pleura was also found, with partial cardiac herniation and pressure of the edge of pericardium on all left-sided coronary arteries simultaneously. The patient was successfully operated and is free of symptoms 4 years later.ConclusionsThis case emphasizes the importance of timely diagnosis and underlines a mechanism that leads to delayed rupture of the tricuspid valve apparatus. Repeated echocardiography in all patients who experienced chest trauma could be of great importance. Also, given the limited value of echocardiography in posttraumatic pericardial rupture and cardiac herniation, cardiac computed tomography should be performed.

Left ventricular herniation and incarceration with infarction secondary to a pericardial defect in a dog

A 2-year-old spayed female Labrador Retriever with clinical signs of heart failure presented to necropsy with a pericardial defect with most of the left ventricle non-reducibly herniated into the pleural space. The herniated cardiac tissue was constricted by a ring of pericardium that allowed subsequent infarction, evidenced by a marked depression on the epicardial surface. A congenital defect was considered more likely than a traumatic cause, since the margin of the pericardial defect was smooth and fibrous. Histologically, the herniated myocardium was acutely infarcted while the epicardium at the defect margin was markedly compressed, including the coronary vessels. This appears to be the first report of ventricular cardiac herniation with incarceration and infarction (strangulation) in a dog. Similar cardiac strangulations may rarely occur in humans with congenital pericardial defects or acquired pericardial defects secondary to blunt trauma or thoracic surgery.

Transesophageal echocardiography for cardiac herniation occurring during robotic-assisted mitral valve repair: a case report

BackgroundCardiac herniation has been reported in thoracic trauma and after pneumonectomy; however, it is sporadic in cardiac surgery.Case presentationA 35-year-old male patient underwent an elective totally endoscopic robotic-assisted mitral valve repair (TERMVR). His hemodynamics were stable after weaning from cardiopulmonary bypass, and no residual mitral valve regurgitation was observed. However, during suturing of the port wound, the patient developed hypotension, which improved with phenylephrine administration. Four-chamber transesophageal echocardiography (TEE) images showed cardiac deformity, and postoperative chest radiography confirmed the dextrocardia. The cardiac herniation was repaired by deflating the left lung and over-inflating the right lung using a double-lumen tube, allowing selective ventilation without re-thoracotomy. The patient was discharged on the sixth postoperative day without complications.ConclusionsThis was a very unusual case of cardiac herniation during TERMVR visualized using distinct TEE images. The cardiac herniation was successfully repaired using a double-lumen tube without re-thoracotomy.

Cardiac herniation: A practical review in the emergency setting.

Albeit described since 1948, cardiac herniations still represent an under-recognized clinical entity in the general population, due to their difficult diagnostic detection and to a limited knowledge in clinical practice. This paper aims to provide an updated overview focusing on definition, clinical presentation and diagnostic work-up of cardiac herniations, as well as on further findings concerning prognoses and available therapeutic options. This narrative review was performed by following the standard methods of the Cochrane Collaboration and the PRISMA statement. A Pubmed search was conducted using the following keywords (in Title and/or Abstract): ("cardiac" OR "heart") AND ("herniation" OR "hernia"). All available high quality resources containing information on epidemiology, etiopathogenesis, clinical findings, diagnostic tools and therapeutic strategies, were included in our search. Causative agents, location and the degree of haemodynamic impairment were found to play a pivotal role in defining the patient's natural history and prognostic outcomes, and in detecting potential associated clinical conditions which may significantly impact on first line decision-making strategy. Cardiac herniations remain a rare and life-threatening pathological injury, whose knowledge is still very limited in clinical practice. Clinicians should be aware of such a clinical entity and of its wide spectrum of clinical manifestations, particularly in high-risk subsets of patients, in order to provide the most appropriate decision-making strategy and timely therapeutic approach.

Surgical Management and Reconstruction of Diaphragm, Pericardium and Chest Wall in Mesothelioma Surgery: A Review.

Mesothelioma is an aggressive disease arising from parietal pleura. Surgery is a valuable option in the frame of a multimodality treatment. Several surgical approaches have been standardized with the aim of a macroscopic complete resection; these often require homolateral diaphragm and pericardial resection and reconstruction. Extrapleural pneumonectomy (EPP) and extended pleurectomy decortication (EPD) have been recognized as radical surgical procedures. Nevertheless, both operations are technically challenging and associated with a significant rate of peri-operative morbidity and non-negligible mortality. The diaphragmatic and pericardial reconstruction technique is mandatory to avoid respiratory impairment and to reduce post-operative complications like gastric and cardiac herniation. Moreover, in the case of localized chest wall recurrence, surgery might be considered a valuable therapeutical option for highly selected and fit patients. All the technical aspects of the resection and reconstruction of the diaphragm, pericardium, and chest wall are described as well as the possible use of new minimally invasive techniques. In addition, the choice of different prosthetic materials, considering the most recent innovations in the field, are discussed.

Cardiac herniation presenting as superior vena cava obstruction syndrome after intrapericardial pnemonectomy for locally advanced lung cancer---case report

IntroductionCardiac herniation is a rare complication after pulmonary surgery, and there are only a few reports about it. We now report a case of cardiac herniation presenting as superior vena cava obstruction after pneumonectomy.Case presentationA-52-years old woman diagnosed right pulmonary squamous cell carcinoma was carried out right pneumonectomy, the pulmonary artery and right superior pulmonary vein were dissected and ligated intrapericardial. The patient developed tachycardia arrhythmias, hypotension, followed by loss of consciousness at about 18 h after operation. After resuscitation, the patient was conscious but developed cyanosis of the superior vena cava drainage area, uropenia, and hypotension (80/30 mmHg). Bedside-echocardiography showed that the SVC was obstructed due to thrombus formation. Chest radiography a shift of the heart into right hemithorax. Rethoracotomy was performed and the herniated heart was replaced into the pericardium, and the pericardium was repaired with Gore Tex patch. The patient recovered smoothly after the second surgery.ConclusionCardiac herniation is a rare and fatally complication after thoracic surgery, and the prompt recognition with timely intervention is life-saving. Cardiac herniation is a rare but fatal complication of pneumonectomy. The increasing frequency of surgical resection for locally advanced thoracic carcinoma has led to a renewed emphasis regarding early diagnosis and treatment for cardiac herniation. Here we discuss a case of cardiac herniation presented with acute superior vena cava obstruction syndrome and hemodynamic instability after intrapericradial right pneumonectomy.

Twenty Year Experience of Thoracic Surgery in a Tertiary Institute for Post TB Sequelae

Aims & Objective: Post TB sequelae like hemoptysis and recurrent chest infections are a source of lot of morbidity around the globe. Many of these patients present to thoracic surgeons and surgical intervention is able to offer significant relief in many of these patients. Methods: Retrospective analysis was carried out for cases operated upon for post TB seqalae in the period from March 1997 to December 2017 in the Thoracic Surgery Department of the National Institute of Tuberculosis and Respiratory Diseases, New Delhi, India. A total of 1325 cases of post TB sequelae were taken up for surgery Out of these, those operated upon primarily for troublesome hemoptysis were 1154 cases. 171 cases were taken up for surgery because they had for recurrent chest infections. Out of these, 558 had tubercular cavities or destroyed lungs, 213 had aspergilloma and post tubercular bronchiectasis was present in 554 cases. Procedures performed were pneumonectomy in 417 patients, lobectomy in 732, bilobectomy in 98, segmental and wedge resections in 16 and thoracoplasty in 62 cases. Results: A total of 60 deaths occurred in this series. There were 18 early and 42 late deaths. 7 patients died of hemorrhage, 4 of respiratory failure, 3 sudden deaths in postoperative period (possible cause-Cardiac arrhythmia or cardiac herniation) and 4 of sepsis. Bronchopleural fistula developed postoperatively in 88 cases, which was managed by tube thoracostomy, followed by thoracoplasty, if required. Other complications like wound infection, atelectasis and pneumonitis were quite manageable. Conclusion: Overall quite gratifying results are achieved if surgical intervention is offered in patients suffering from debilitating post TB symptoms in carefully selected and well prepared cases.

Blunt Thoracic Trauma-Induced Mitral Papillary Muscle Avulsion with Pericardial Rupture and Cardiac Herniation: Difficult and Delayed Diagnoses

Blunt thoracic trauma (BTT) and the resultant isolated mitral papillary muscle avulsion, pericardial rupture, and cardiac herniation injuries are each rarely diagnosed clinical entities. We describe the first case of combined pericardial tear with cardiac herniation and ruptured mitral papillary muscles following BTT. Preoperative transesophageal echocardiography (TEE) diagnosed the delayed mitral papillary muscle rupture while all previous diagnostic modalities failed to delineate the pericardial rupture and cardiac herniation. Particular emphasis is placed on the clinical and radiologic aspects of the case that would heighten clinical suspicion in the emergency setting where blunt cardiac injury sequelae are suspected and frequently missed.

Case report: cardiac herniation following robotic-assisted thymectomy

BackgroundThe first reported case of cardiac herniation was in 1948 and occurred following pericardiectomy during a lung cancer resection. Although rare, this potentially fatal surgical complication may occur following any operation in which a pericardial incision or resection is performed. The majority of literature on cardiac herniation involves case reports after intrapericardial pneumonectomy. Currently, there are no reports of cardiac herniation after thymectomy with pericardial resection.Case presentationA 44-year-old Asian female with symptomatic myasthenia gravis was referred for thymectomy. Originally thought to have Bell’s Palsy, her symptoms began with right eyelid drooping and facial weakness. Over time, she developed difficulty holding her head up, upper extremity weakness, difficulty chewing and dysarthria. These symptoms worsened with activity. She was found to have positive acetylcholine receptor binding antibody on her myasthenia gravis panel. A preoperative CT scan demonstrated a 3.5 cm × 2 cm anterior mediastinal mass along the right heart border and phrenic nerve. A complete thymectomy, via right-sided robotic-assisted approach was performed en bloc with a portion of the right phrenic nerve and a 4 cm × 4 cm portion of pericardium overlying the right atrium and superior right ventricle. Upon undocking of the robot and closure of the port sites, the patient became acutely hypotensive (lowest recorded blood pressure 43/31 mmHg). The camera was reinserted and demonstrated partial cardiac herniation through the anterior pericardial defect toward the right chest. An emergent midline sternotomy was performed and the heart was manually reduced. The patient’s hemodynamics stabilized. A vented Gore-Tex 6 cm × 6 cm patch was sewn along the pericardial edges with interrupted 4–0 prolene to close the pericardial defect.ConclusionThis potentially fatal complication, although rare, should always be considered whenever there is hemodynamic instability entry or resection of the pericardium during surgery. We now routinely sew in a pericardial patch using our robotic surgical system for any defect over 3 cm × 3 cm that extends from the mid- to inferior portions of the heart.

Comprehensive review of pericardial diseases using different imaging modalities.

Pericardial abnormalities are common cardiovascular disease entity, which are encountered in various clinical settings. Imaging plays an integral role in evaluation of pericardial abnormalities. The appropriate use of multiple imaging modalities is crucial to initiate the diagnosis and guide the referring providers to establish a management plan. Echocardiography (echo) is the initial imaging modality of choice. Computed tomography (CT) and magnetic resonance imaging (MRI) are complementary imaging tools with better tissue characterization. Pericardial abnormalities include pericardial effusion, pericarditis, pericardial constriction, tamponade, pneumopericardium, pericardial rupture, fistulas, congenital abnormalities, and pericardial tumors. Pericardial effusion is a common clinical entity, where there is accumulation of fluid in the pericardial sac. Pericarditis can be acute, incessant, chronic, or recurrent. Pericardial thickening or enhancement are the main CT findings in acute pericarditis. Pericardial constriction results into diastolic heart failure. Differentiating constrictive pericarditis from restrictive cardiomyopathy is important, since these conditions can present with similar clinical and hemodynamic findings and both have different management. Right atrial or right ventricular compression by the pericardial sac contents should raise the suspicion for tamponade. Immediate pericardiocentesis to release the elevated intra-pericardial pressure can be lifesaving. Pericardial rupture is a serious condition that can occur after trauma and can lead to cardiac herniation. The main purpose of this article is to do a comprehensive review of the imaging appearance of pericardial diseases on different imaging modalities and establish a structured diagnostic approach for pericardial diseases to appropriately guide management.

Atrial Resection without Cardiopulmonary Bypass for Lung Cancer.

Results of resection of lung cancer invading left atrium (T4atrium) without cardiopulmonary bypass (CPB) remain controversial. We reviewed our experience analyzing surgical results and postoperative outcomes. Patients who underwent extended lung resection for T4atrium without CPB between 1998 and 2018 were retrospectively reviewed using a prospective database. The study included 44 patients (34 males and 10 females; median age: 63 years). Twenty-five patients underwent preoperative mediastinal staging and 27 received induction treatment (IT). Surgery included 40 (90.9%) pneumonectomies, 3 (6.8%) lobectomies, and 1 bilobectomy (2.3%). Pathological nodal status was N0 in 10 patients (22.7%), N1 in 18 (40.9%), and N2 in 16 (36.4%). Four patients receiving IT had a complete pathological response (9.1%). Eight (18.2%) patients had microscopic tumor evidence on atrial resected margins. Mortality was nil. The major complication rate was 11.4%, including one bronchopleural fistula, one cardiac herniation, and three hemothoraces, all requiring reintervention. The minor complication rate was 25.5%. After a median survival of 37 months (range: 1-144 months), 20 (45.4%) patients were alive. Five-year survival rate and disease-free interval were 39 and 45.8%, respectively. Patients with N0 and R0 disease had a best prognosis (log-rank test: p = 0.03 and p = 0.01, respectively). IT neither influenced survival nor postoperative complications. On multivariate analysis, pN0 (p = 0.04 [95% confidence interval [CI]: 0.65-9.66] and negative atrial margins (p = 0.02 [95% CI: 0.96-8.35]) were positive independent prognostic factors. T4atrium is technically feasible without mortality and acceptable morbidity. Patients with N2 cancers should not be operated. T4atrium should not be systematically considered as a definitive contraindication to surgery.

Extra-pleural pneumonectomy.

The extra-pleural pneumonectomy (EPP) is a standardised surgical procedure born for pleural tuberculosis and later used in pleural cancer treatment, especially in malignant pleural mesothelioma (MPM). This systematic review aimed to focus on the actual overall EPP role in surgical oncology. The literature search was performed from January 1985 to January 2018 In PubMed, Embase, and Cochrane according to PRISMA protocol. The search was restricted to publications in English with the research words "extrapleural pneumonectomy", "malignant pleural mesothelioma", "pleural malignancies". The results were then filtered focusing only on papers with series of patients treated with EPP, for mesothelioma and non-mesothelioma malignancies. The search was restricted to publications in English. We found a 5-year overall survival (OS) ranging from 0 to 78%. The peri-operative mortality and morbidity ranged from 0 to 11.8% and 0 to 82.6%, respectively. The most represented and described post-operative complications reported were ARDS, pericardial tamponade, cardiac herniation, pulmonary embolism, respiratory infections, respiratory failure, atrial arrhythmia, myocardial infarction. In referral centres and selected patients, EPP is a cytoreductive or radical surgical treatment in extended pleural malignancies. Prospective studies are needed to standardise the timing of the procedure in a multimodality treatment program, according to the oncological and functional indications, to keep an acceptable complications rate and post-operative quality of life status.

Blunt Traumatic Pericardial Rupture with Traumatic Amaurosis Fugax Presenting as Massive Haemothorax: A Conundrum?

Introduction: Blunt traumatic pericardial rupture (BTPR) or traumatic pericardiotomy is a rare typical trauma. It is usually discovered at autopsy. Surgical repair is mandatory especially if prompt diagnosis is made because of the associated high mortality. Clinical Case: We report the successful management and survival of BTPR patient after chest trauma presenting with massive haemothorax and transient loss of vision, necessitating urgent surgical treatment. The patient was involved in a road traffic accident having a head-on collision with the rear of the vehicle ahead whiles trying to overtake it. Discussion: It is usually discovered at autopsy or during emergent surgical exploration through either sternotomy or thoracotomy [1] due to its delayed diagnosis, unusual presentation, association with other major cardiopulmonary injuries and complications such as cardiac herniation, fatal arrhythmias, cardiogenic shock and cardiac arrest. Conclusion: Blunt traumatic pericardial rupture should be suspected in any patient in whom hemodynamic instability occurs rapidly after trauma without evidence of major bleeding. Prompt surgical exploration may yield excellent results.

Extrapleural pneumonectomy- perioperative anaesthetic conduct

Malignant mesothelioma is a rare tumour arising from mesothelial lining that mostly occurs in the pleura with survival of around 12 months. 1 Extrapleural pneumonectomy, which is the mainstay of treatment for locally advanced malignant pleural mesothelioma, presents a great challenge to anaesthesiologists as it can be associated with high perioperative morbidity and mortality. We present a case report on anaesthetic management for extrapleural pneumonectomy in a 64-year-old patient with advanced malignant pleura mesothelioma. Our case report highlights: crucial role of anaesthetic management in reducing perioperative complications by better knowledge of physiology and technical aspects of the surgery; issues and challenges related to the anaesthetic management such as invasive monitoring, lung isolation, protective lung ventilation strategy, appropriate fluid management and adequate analgesia to enable extubation post-surgery in the operating room; high vigilance for diagnosing life-threatening complications such as cardiac herniation; team working and collaboration with surgeon to improve patient outcome and post-operative monitoring and management.
