Impact of One-Lung Ventilation on Oxygenation and Ventilation Time in Thoracoscopic Heart Surgery: A Comparative Analysis with Median Thoracotomy.

BACKGROUND One-lung ventilation is the separation of the lungs by mechanical methods to allow ventilation of only one lung, particularly when there is pathology in the other lung. This retrospective study from a single center aimed to compare 49 patients undergoing thoracoscopic cardiac surgery using one-lung ventilation with 48 patients undergoing thoracoscopic cardiac surgery with median thoracotomy. MATERIAL AND METHODS This single-center retrospective study analyzed patients who underwent thoracoscopic cardiac surgery based on one-lung ventilation (experimental group, n=49). Other patients undergoing a median thoracotomy cardiac operation were defined as the comparison group (n=48). The oxygenation index and the mechanical ventilation time were also recorded. RESULTS There was no significant difference in the immediate oxygenation index between the experimental group and comparison group (P>0.05). There was no significant difference for the oxygenation index between men and women in both groups (P>0.05). The cardiopulmonary bypass time significantly affected the oxygenation index (F=7.200, P=0.009). Operation methods (one-lung ventilation thoracoscopy or median thoracotomy) affected postoperative ventilator use time (F=8.337, P=0.005). Cardiopulmonary bypass time (F=16.002, P<0.001) and age (F=4.384, P=0.039) had significant effects on ventilator use time. There was no significant effect of sex (F=0.75, P=0.389) on ventilator use time. CONCLUSIONS Our results indicated that one-lung ventilation thoracoscopic cardiac surgery did not affect the immediate postoperative oxygenation index; however, cardiopulmonary bypass time did significantly affect the immediate postoperative oxygenation index. Also, one-lung ventilation thoracoscopic cardiac surgery had a shorter postoperative mechanical ventilation use time than did traditional median thoracotomy cardiac surgery.

Anterolateral Thoracotomy: A Novel and Simple Technique to Improve the Closure Using the Self Locking Knot.

Thoracotomy is defined as an incision made by the surgeon in the chest wall in order to allow visibility of the thoracic cavity content. This can be used by surgeons to treat thoracic cavity content diseases including the heart, lungs, esophagus, and other organs. Thoracic incision closure remains an item with no consensus. Therefore, we present an easy way and give a little tip for closure using the slipknot that will allow the correct approach of ribs and the successful closure of the intercostal space.

Continuous serratus posterior superior intercostal plane block for postoperative analgesia management in the patient who underwent right atrial mass excision: a case report.

Serratus posterior intercostal plane block (SPSIPB) is a novel periparavertebral block. It provides anterolateral posterior chest wall analgesia. It is an interfascial plane block, performed under ultrasound guidance, and the visualization of landmarks is easy. It is performed deep into the serratus posterior superior muscle at the level of the third rib. Until now, there have been case reports about the usage of single-shot SPSIPB, but there are no reports about the usage of the block catheterization technique of SPSIPB. Continuous infusion from a catheter of interfascial plane blocks is important for postoperative analgesia management after painful surgeries such as thoracic and cardiac surgeries. Thus, we performed SPSIPB catheterization in a patient who underwent right atrial mass excision with minimally invasive thoracotomy surgery. Here, we present our successful analgesic experience with continuous SPSIPB in this case report.

Effect of right anterolateral thoracotomy versus median sternotomy on postoperative wound tissue repair in patients with congenital heart disease: A meta-analysis.

Right anterolateral thoracotomy (RAT) and median sternotomy (MS) are two major methods for treatment of congenital cardiac disease. But there are various types of surgery that provide a better operative outcome for the patient. Therefore, we carried out a meta-analysis to investigate the effects of these two methods in the treatment of wound tissue, hospitalization and so on, to find out which surgery method could provide the best short-term effect. In this research, we chose an English controlled trial from 2003 to 2022 to evaluate the influence of right anterolateral thoracotomy and median sternotomy on the short-term outcome of Cardiopulmonary bypass (CPB), time of operation, time spent in the hospital, and the time of scar formation. Our findings suggest that the RAT method was associated with a shorter surgical scars for congenital heart disease operations compared to MS with respect to post-operation scars (WMD, 3.55; 95% CI, 0.04, 7.05; p = 0.05). The RAT method is better suited to the needs of patients who care about their injuries. Nevertheless, in addition to other surgery related factors which might affect post-operative wound healing, we discovered that MS took a shorter time to perform CPB compared with RAT surgery (WMD, - 1.94; 95% CI, -3.39, -0.48; p = 0.009). Likewise, when it comes to the time taken to perform surgery, MS needs less operational time compared to RAT methods (WMD, -12.84; 95% CI, -25.27, -0.42; p = 0.04). On the other hand, the time needed for MS to recover was much longer compared to the RAT (WMD, 0. 60; 95% CI, 0.02, 1.18; p = 0.04). This indicates that while RAT is advantageous in terms of shortening the duration of post-operative scar, it also increases the time needed for surgical operations and CPB.

[Mitral valve surgery via minimally invasive and conventional access]. / Mitral'naya khirurgiya iz mini- i traditsionnogo dostupov.

OBJECTIVE: To compare the immediate results of mini-thoracotomy and sternotomy in patients with mitral valve disease. MATERIAL AND METHODS: The study included 52 patients who underwent mitral valve surgery (25 cases - mini-thoracotomy, 27 cases - sternotomy). RESULTS: Aortic cross-clamping time was significantly longer in sternotomy compared to mini-thoracotomy group - 110 vs 94 min (p=0.03). Ventilation time was also significantly longer in the sternotomy group (12 vs. 8 hours, p=0.01). Postoperative morbidity was similar (postoperative wound infection, neurological complications, coronavirus disease, overall in-hospital mortality). CONCLUSION: In addition to cosmetic effect, minimally invasive approach in mitral valve surgery has some other advantages including less duration of aortic cross-clamping and mechanical ventilation, availability of reconstructive interventions due to better exposition of the mitral valve and subvalvular structures.

[Surgical treatment of chondromyxoid fibroma of ribs via thoracoabdominal access]. / Khirurgicheskoe lechenie khondromiksoidnoi fibromy reber iz kombinirovannogo torakoabdominal'nogo dostupa.

Surgical treatment of chondromyxoid fibroma of ribs is described. The diagnosis was verified after histological analysis. The patient underwent resection of multinodular tumor of anterolateral thoracic wall invading abdominal cavity via thoracoabdominal access. Postoperative period was uneventful. This case demonstrates the need for total en-bloc resection of tumor with surrounding tissues. Surgery is the only effective method for these patients.

Improvements in perioperative outcomes for non-small cell lung cancer: a decade-long analysis.

BACKGROUND: Video-assisted thoracic surgery (VATS) procedures for non-small cell lung cancer (NSCLC) have steadily increased and have become the gold standard, but their prognostic advantage compared with thoracotomy has not been elucidated. This study retrospectively evaluated perioperative characteristics of VATS for NSCLC over time. METHODS: We collected the clinical data of 760 patients with NSCLC who underwent pulmonary resection over the past decade, classifying patients into early (2011-2015) and late (2016-2020) periods. Changes in NSCLC patient characteristics, surgical approaches, perioperative factors, postoperative morbidities, and prognoses were analyzed. RESULTS: Patients in the late period were older (p = 0.01), had more comorbidities (p = 0.01), and had earlier-stage cancer (p < 0.01) than those in the early period. The late period had significantly fewer surgical procedures for lobectomy or extended resection beyond lobectomy (p < 0.01), open thoracotomies (p < 0.01), postoperative (p = 0.02) and severe morbidities (p < 0.01), and a significantly shorter postoperative hospital stay than the early period. Surgical procedures of lobectomy or extended resection beyond lobectomy (p < 0.01) were significant risk factors for postoperative morbidity, and being in the early period (p < 0.01) and surgical procedures of lobectomy or extended resection beyond lobectomy (p < 0.01) were significant risk factors for severe postoperative morbidities. The overall survival prognosis significantly differed between the groups (p = 0.02) but progression-free survival did not (p = 0.89). CONCLUSIONS: The incidence of postoperative morbidities decreased over time in older patients and patients with more comorbidities. The prognosis of patients with NSCLC did not change with increasing VATS or sublobar resection.

Can Minimally Invasive Multivessel Coronary Revascularization Be a Routine Approach?

BACKGROUND: Advancement in the field of cardiovascular surgery has emerged with various minimally invasive approaches for the treatment of multivessel coronary disease to improve outcomes and minimize the burden associated with conventional cardiac surgery. This study describes our routine technical approach and clinical experience of minimally invasive coronary artery bypass via left anterior minithoracotomy for the treatment of patients with multivessel coronary lesions. METHODS: Our experience includes 100 consecutive patients who were operated between July 2020 and April 2021. The left internal thoracic artery was harvested in all patients. Radial arterial grafts and saphenous vein grafts were harvested endoscopically. Patients were operated either under cardiopulmonary bypass (CPB) with blood cardioplegia through left anterior minithoracotomy of 5 to 7 cm or off-pump via left anterolateral minithoracotomy. RESULTS: We had single mortality (1%), no early postoperative myocardial infarction was observed. None of our patients was converted to sternotomy (0%). The mean number of bypass was 3.1 ± 0.8, the mean cross-clamping time was 78.1 ± 20.6 minutes, the mean CPB time was 153.2 ± 37.5 minutes, the average intubation time was 6.33 ± 11.29 hours, the mean intensive care unit stay was 1.62 ± 1.78 days, the mean hospital stay was 4.98 ± 3.01 days, the average total operation time was 4.20 ± 0.92 hours, and the average pleural drain was 393.8 ± 169.7 mL. CONCLUSION: Minimally invasive coronary artery bypass grafting via left anterior minithoracotomy can be routinely performed with safety and it is feasible, reproducible with a short learning curve. Further multicenter studies are needed for the standardization of our technique.

Early Results of Total Coronary Revascularization via Left Anterior Thoracotomy.

BACKGROUND: Avoidance of sternotomy while preserving complete revascularization remains challenging in multivessel coronary disease. Technical issues and in-hospital outcomes of total coronary revascularization via a small left anterior thoracotomy (TCRAT) in nonselected patients with multivessel disease are reported. METHODS: From November 2019 to September 2021, coronary artery bypass grafting via left anterior minithoracotomy on cardiopulmonary bypass and cardioplegic cardiac arrest was performed in 102 patients (92 males; 67 ± 10 [42-87] years). Slings were placed around ascending aorta, left pulmonary veins, and inferior vena cava for exposure of lateral and inferior ventricular wall. All patients had multivessel coronary disease (three-vessel disease: n = 72; two-vessel disease: n = 30; left main stenosis: n = 44). We included patients at old age (> 80 years, 14.7%), with severe left ventricular dysfunction (ejection fraction < 30%, 6.9%), massive obesity (body mass index > 35, 11.6%), and at increased risk (EuroSCORE II > 4, 15.7%). RESULTS: Left internal thoracic artery (n = 101), radial artery (n = 83), and saphenous vein (n = 39) grafts were used for total (61.8%) or multiple (19.6%) arterial grafting. A total of 323 distal anastomoses (3.2 ± 0.7 [2-5] per patient) were performed to revascularize left anterior descending (100%), circumflex (91.2%), and right coronary artery (67.7%). Complete revascularization was achieved in 95.1%. In-hospital mortality was 2.9%, stroke rate was 1.0%, myocardial infarction rate was 2.9%, and repeat revascularization rate was 2.0%. CONCLUSION: This novel surgical technique allows complete coronary revascularization in the broad majority of multivessel disease patients without sternotomy. TCRAT can be introduced into clinical routine safely. Long-term results remain to be investigated.

Comparison of Minimally Invasive Valve Surgery: Hemi-Sternotomy vs. Right Anterolateral Thoracotomy Incision.

Objective: This study aims to compare patient data from two different surgical approaches for minimally invasive valve surgery: hemi-sternotomy and right anterolateral thoracotomy. The primary objective is to determine the safety and efficacy of both surgical incisions. Methods: Between December 2019 and December 2022, a total of 90 patients underwent minimally invasive valve surgery at our center. Among them, 36 patients received the hemi-sternotomy incision with an average age of 45.86 ± 14.83, and 54 patients received the right anterolateral thoracotomy with an average age of 56.77 ± 14.83 years. In the hemi-sternotomy group, 21 patients underwent aortic valve surgery, and 15 had mitral valve surgery, while in the right anterolateral thoracotomy group, 30 patients underwent aortic valve surgery, and 15 patients had mitral valve surgery. Results: No deaths or significant bleeding occurred in the hemi-sternotomy group. However, in the right anterolateral thoracotomy group, one patient died from continuous low cardiac output syndrome after surgery, and one patient suffered a femoral artery dissection. All other patients were discharged without complications. The aortic clamp time and the cardiopulmonary bypass time were significantly lower in the hemi-sternotomy group compared to the right anterolateral thoracotomy group. Conversely, the two groups had no significant differences in intubation time, 24-hour drainage, hospitalization time, and blood transfusion. On the second day after surgery, serum c-TNT and NT-PROBNP levels significantly increased in both groups, but they were significantly higher in the right anterolateral thoracotomy group than in the hemi-sternotomy group. However, on the fifth day after surgery, serum c-TNT and NT-PROBNP levels decreased significantly in both groups, with no significant differences between them. Conclusions: Minimally invasive valve surgery, whether performed with right anterolateral thoracotomy or hemi-sternotomy, is safe and effective after the learning curve. Patients can benefit from these advances in minimally invasive cardiac surgery, and surgeons can easily master these techniques.

Initial perioperative outcomes of robot-assisted thoracoscopic lobectomy using a confronting setting.

PURPOSE: Most robot-assisted thoracoscopic surgery (RATS) is performed from the vertical view. This study evaluates the initial outcomes of our novel confronting RATS technique, in which the patient was viewed horizontally, as in open thoracotomy. METHODS: We reviewed data on patients who underwent thoracoscopic lobectomy between January, 2019 and April, 2022. Perioperative outcomes were compared between RATS and video-assisted thoracoscopic surgery (VATS), using propensity-score matching. RESULTS: RATS and VATS were performed for 83 and 571 patients, respectively. After propensity-score matching, data on 81 patients from each of the two groups were retrieved. The operative time was significantly longer for RATS than for VATS (199 ± 44 min vs. 173 ± 37 min, p < 0.001). There was no mortality or conversion to thoracotomy in either of the groups. The rates of overall complications and prolonged air leak did not differ significantly between the groups. The serum creatine phosphokinase level on postoperative day 4 was higher after RATS than after VATS. The number of resected lymph nodes and the rates of nodal upstaging did not differ significantly between the groups. CONCLUSION: The initial perioperative outcomes of RATS using the confronting settings were comparable to those of VATS.

Impact of right anterolateral thoracotomy with a new approach on breast development: survey analysis of female cardiac surgery patients.

INTRODUCTION: Our aim was to present the effects of submammarian thoracotomy by our new approach to breast development in young female patients between 8 and 14 years old. METHODS: Atrial septal defect closure was performed in 55 female patients between 8 and 14 years old at the time of operation between January 2010 and January 2018 by median sternotomy or right anterolateral thoracotomy. These patients were called for a follow-up visits, breast examination were performed, and a questionnaire of 10 questions was applied. RESULTS: According to the answer given by the patients to the question of "how would you describe your scar" showed that the surgical method satisfies all patients cosmetically in study group. The overall satisfaction rate for the cosmetic results of operation was 100% versus 41.1%, respectively. The percentage of patients said no to the question "Do you experience lack of self-confidence related your scar" was significantly higher than the control group (p < 0.001). The percentage of those who said yes to the question "Would you like to be operated with the same approach if you will have surgery again?" in the study group was significantly higher than the control group (p = 0.002). CONCLUSIONS: We consider that our procedure is safe and effective with improved cosmetic results compared to median sternotomy which also confers many advantages such as less trauma, less pain, faster recovery, and shorter hospital stay. This study presents one of the largest series of paediatric patients operated by submammarian thoracotomy.

Short-term outcomes of thoracoscopic versus open lobectomy for congenital lung malformations.

PURPOSE: Thoracoscopic and open approaches for the management of congenital lung malformations (CLM) has been debated. The aim of this study is to compare 30-day outcomes for non-emergent lobectomies in children. METHODS: The National Surgical Quality Improvement Program-Pediatric database was queried for patients undergoing CLM resection from 2013 to 2020. Outcomes were compared by operative technique in an intention-to-treat model and then propensity matched. RESULTS: 2157 patients met inclusion criteria and underwent non-emergent pulmonary lobectomy for CLM. The intended operative approach was thoracoscopic in 57.7% of patients. Patients in the open group compared to the thoracoscopic were more likely to be born premature, have chronic lung disease, require preoperative oxygen support, and be ventilator dependent. After propensity matching, there was no statistically significant difference in 30-day mortality, unplanned readmission, and other complications between the thoracoscopic and open groups. Thoracoscopic approach was associated with a shorter length of stay. The proportion of cases approached via thoracoscopy increased over time from 48.8% in 2013 to 69.9% in 2020. CONCLUSIONS: This large multicenter retrospective matched analysis demonstrates thoracoscopic lobectomy in children has similar favorable 30-day outcomes and shorter length of stay for the non-emergent management of CLM, compared to open thoracotomy. LEVEL OF EVIDENCE: Level III.

Minithoracotomy vs Conventional Sternotomy for Mitral Valve Repair: A Randomized Clinical Trial.

Importance: The safety and effectiveness of mitral valve repair via thoracoscopically-guided minithoracotomy (minithoracotomy) compared with median sternotomy (sternotomy) in patients with degenerative mitral valve regurgitation is uncertain. Objective: To compare the safety and effectiveness of minithoracotomy vs sternotomy mitral valve repair in a randomized trial. Design, Setting, and Participants: A pragmatic, multicenter, superiority, randomized clinical trial in 10 tertiary care institutions in the UK. Participants were adults with degenerative mitral regurgitation undergoing mitral valve repair surgery. Interventions: Participants were randomized 1:1 with concealed allocation to receive either minithoracotomy or sternotomy mitral valve repair performed by an expert surgeon. Main Outcomes and Measures: The primary outcome was physical functioning and associated return to usual activities measured by change from baseline in the 36-Item Short Form Health Survey (SF-36) version 2 physical functioning scale 12 weeks after the index surgery, assessed by an independent researcher masked to the intervention. Secondary outcomes included recurrent mitral regurgitation grade, physical activity, and quality of life. The prespecified safety outcomes included death, repeat mitral valve surgery, or heart failure hospitalization up to 1 year. Results: Between November 2016 and January 2021, 330 participants were randomized (mean age, 67 years, 100 female [30%]); 166 were allocated to minithoracotomy and 164 allocated to sternotomy, of whom 309 underwent surgery and 294 reported the primary outcome. At 12 weeks, the mean between-group difference in the change in the SF-36 physical function T score was 0.68 (95% CI, -1.89 to 3.26). Valve repair rates (≈ 96%) were similar in both groups. Echocardiography demonstrated mitral regurgitation severity as none or mild for 92% of participants at 1 year with no difference between groups. The composite safety outcome occurred in 5.4% (9 of 166) of patients undergoing minithoracotomy and 6.1% (10 of 163) undergoing sternotomy at 1 year. Conclusions and relevance: Minithoracotomy is not superior to sternotomy in recovery of physical function at 12 weeks. Minithoracotomy achieves high rates and quality of valve repair and has similar safety outcomes at 1 year to sternotomy. The results provide evidence to inform shared decision-making and treatment guidelines. Trial Registration: isrctn.org Identifier: ISRCTN13930454.

Introduction of pediatric thoracoscopic lung resections in a low-volume center - feasibility, outcome and cost analysis.

BACKGROUND: Early series of pediatric thoracoscopic surgery have reported high conversion rates and significant complications. This study investigated the introduction of pediatric thoracoscopic lung resections in a low-volume center with reference to corresponding open thoracotomy procedures with regards to operative times, length of stay, cost of admission, and outcomes. METHODS: A single surgeon series. Data from the first 10 consecutive thoracoscopic lung resections were compared to a cohort of 10 consecutive open lung resections performed before the introduction of the thoracoscopic technique. All operations were performed between December 2015 and October 2021. The median follow-up was 34 months (range 4-65). RESULTS: The cohort included 14 lobectomies (8 thoracoscopic and 6 open) for congenital pulmonary airway malformation (CPAM), and 6 resections (mainly non-anatomic) of pulmonary sequestration (2 thoracoscopic and 4 open). One lobectomy required conversion to thoracotomy, and one patient required reinsertion of a chest drain after open lobectomy due to persistent air leak. No other complications were recorded. All patients were asymptomatic at their follow-up. There was no significant difference in the mean age, mean weight, operative times, and intraoperative blood loss between open and minimally invasive procedures. Thoracoscopic technique was associated with significantly shorter stay at pediatric intensive care unit and shorter overall inpatients stay. CONCLUSION: Thoracoscopic lung resections can be safely introduced in a low-volume center with comparable cost, operative time, and results and significantly shorter inpatient stay.

Lateral thoracotomy versus sternotomy for left ventricular assist device implantation.

PURPOSE OF REVIEW: Traditionally, left ventricular assist devices (LVADs) are implanted via the standard median sternotomy approach. However, a left thoracotomy approach has been purported to offer physiologic benefits. As a result, utilization of the left thoracotomy for LVAD placement is increasing globally, but the benefits of this approach versus sternotomy are still evolving and debatable. This review compares the median sternotomy and thoracotomy approaches for LVAD placement. RECENT FINDINGS: Recent meta-analyses of LVAD implantation via thoracotomy approach suggest that the thoracotomy approach was associated with a reduced incidence of RVF, bleeding, hospital length of stay (LOS), and mortality [1 ▪▪ ,2 ▪▪ ] . No difference in stroke rates was noted. These results offer support as to the feasibility of a thoracotomy approach for LVAD implantation but also highlight its potential superiority over sternotomy. SUMMARY: The most recent literature supports the use of lateral thoracotomy for placement of left ventricle assist devices compared to median sternotomy. Long-term outcomes from lateral thoracotomy are still unknown, however, short-term results favor lateral thoracotomy approaches for LVAD implantation. While the conventional median sternotomy approach was the original operative technique of choice for LVAD implantation, lateral thoracotomy is quickly emerging as a potentially superior technique.

Effect of thoracoscopic and thoracotomy on postoperative wound complications in patients with lung cancer: A meta-analysis.

Because of the difficult surgical procedures, patients with lung cancer who have received thoracic surgery tend to have postoperative complications. It may lead to postoperative complications like wound infection, wound haematoma and pneumothorax. A lot of research has assessed the effect of various surgery methods on postoperative complications in pulmonary cancer. The purpose of this meta-analysis is to establish if thoracoscopic is superior to that of thoracotomy in the rate of post-operative complications. From the beginning to the end of June 2023, we performed an exhaustive search on four main databases for key words. The Hazard of Bias in Non-Randomized Interventional Studies (ROBINS-I) was evaluated in the literature. In the end, 13 trials that fulfilled the eligibility criteria underwent further statistical analyses. The results showed that thoracoscopic intervention decreased the risk of post operative wound infection (dominant ratio [OR], 3.00; 95% confidence margin [CI], 1.98, 4.55; p < 0.00001) and air-leakage after operation (OR, 1.30; 95% CI, 1.04, 1.63; p = 0.02). There was no statistically significant difference between the two groups in terms of the rate of haemorrhage after operation (OR, 0.10; 95% CI, 0.73, 1.66; p = 0.63). Our findings indicate that thoracoscopic is less likely to cause post operative infection and gas leakage than thoracotomy, and it does not decrease the risk of postoperative haemorrhage. As some of the chosen trials are too small to conduct meta-analyses, care must be taken when handling the data. In the future, a large number of randomized, controlled trials will be required to provide additional evidence for this research.

[Retrograde S(9+)10 Segmentectomy without Interlobar Fissurelectomy].

BACKGROUNDS: With increase of patients with a small-sized lung cancer, there is an increasing need for minimally invasive lung segmentectomy that can preserve respiratory function. We perform S(9+)10 segmentectomy with retrograde dissection of the pulmonary vein, bronchus, pulmonary artery, in order, without interlober fissurelectomy and staple dissection of the peripheral lung parenchyma. METHODS: Seven patients who underwent retrograde S(9+)10 segmentectomy between June, 2021 and May, 2022 in our hospital were retrospectively reviewed. RESULTS: No patient was converted to the open thoracotomy, without any complications including prolonged air leakage. The average operation time was 171 minutes( range 125 to 221), amount of bleeding was 25 ml( range 0 to 75). Median duration of chest tube insertion was 4 days( range 3 to 6), length of stay after surgery was 6 days (range 5 to 9). Pathologic stage showed pT1mi in 3 patients, pT1a in 3 patients, pT2a in 1 patient. No local recurrence was seen at this time. CONCLUSIONS: Retrograde S(9+)10 segmentectomy is feasible and facilitates interlobar procedure at the time of repeated segmentectomy or completion lobectomy.

[Solitary Fibrous Tumor of Pleura Communicating with Pulmonary Artery and Vein].

A 68-year-old man was noted to have an abnormal shadow on chest X-ray. Chest computed tomography (CT) showed a 100 mm mass in the lower right thoracic cavity. The mass was lobulated and compressed the surrounding lung tissue and diaphragm. Contrast-enhanced CT showed that the mass was heterogeneously enhanced and contained expanded blood vessels within it. The expanded vessels communicated with the pulmonary artery and vein via the diaphragmatic surface of the right lung. The mass was diagnosed as a solitary fibrous tumor of the pleura (SFTP) by CT-guided lung biopsy. We performed partial resection of the lung including the tumor via right eighth intercostal lateral thoracotomy. Intraoperative examination showed that the tumor was pediculated from the diaphragmatic surface of the right lung. The stem was about 3 cm long and easily cut with a stapler. The tumor was definitively diagnosed as a malignant SFTP. No recurrence was found for 12 months postoperatively.

Our experience with solitary fibrous tumors in the chest area.

The article reports on three patients with a solitary fibrous tumor of the chest. The first patient had a tumor in the area of the dome of the right pleural cavity which was radically resected together with the chest wall around its origin. In the second case, the tumor was attached by a vascular pedicle to the lower lobe of the right lung. This tumor was resected atypically, via thoracotomy, along with a margin of healthy lung tissue at the base of its pedicle. The last patient had a tumor of the lower lobe of the right lung, surrounding the lower pulmonary vein, which did not have a clear margin of healthy lung tissue. This finding required right lower lobectomy via posterolateral thoracotomy. The presented cases describe rare types of tumors in the chest area which at the time of detection often reach large dimensions, necessitating extensive surgical procedures. Due to the biological nature of these tumors, long-term patient follow-up is advisable.
