Background: The aim of this study is to report the early outcomes of valvular heart surgeries performed via the right thoracotomy approach. While thoracotomy with femoro-femoral bypass is an established method for minimally invasive open-heart surgeries, thoracotomy with conventional cannulation is still being explored. In our center, we conducted 958 valvular heart surgery cases using the right anterolateral thoracotomy approach with central cannulation and data were analyzed.

Methods: This is a retrospective observational study based on prospectively collected data from patients who underwent valvular heart surgery at our center spanning from April 2013 to April 2023. The data encompass demographics, procedures, operative techniques, post-operative morbidity, mortality, and a 1-month follow-up.

Results: Our study revealed no procedure-related mortality. No patient required conversion to median sternotomy. Smooth cannulation and satisfactory exposure were achieved in all patients. The study encompassed a wide age range, from 14 to 68 years, with 618 female patients (64.5%) and 340 male patients (35.5%). The average cross-clamp time ranged from 38 to 90 min, the duration of cardio-pulmonary bypass ranged from 45 to 105 min, post-operative extubation ranged from 3 to 8 h, the average drain volume ranged from 100 to 350 ml, and the incision size ranged from 5 to 7 cm.

Conclusions: Our data demonstrate that conventional cannulation via the right antero-lateral thoracotomy approach for valvular heart disease is a viable alternative to reduce the side effects associated with sternotomy and femoral cannulation. This procedure is safe, reproducible, and provides the same level of treatment quality.

A 54-year-old female presented with recurrent abdominal pain and new onset chest pain. Chest computed-tomography angiogram detected a thoracic aortic aneurysm with suspected Type A intramural hematoma (IMH) versus aortitis. Initially, conservative management was pursued while awaiting a definitive diagnosis. Differential workup was negative, while additional imaging modalities favored IMH, prompting expedited surgical intervention. During ascending aortic and hemiarch replacement, severe aortitis was unexpectedly discovered without evidence of IMH. Histopathological examination of the aortic specimens identified transmural aortic inflammation with lymphoplasmacytic infiltrate and irregular fibrosis. Numerous IgG4-positive plasma cells were present with IgG4/IgG ratio of 40-50% suggesting IgG4-related disease (IgG4-RD). Subsequent analysis revealed B cells positive for clonal IgH gene rearrangement, and bone marrow biopsy then revealed the same clonal B cells. She was ultimately diagnosed with CLL, the most common phenotype of monoclonal B-cell lymphocytosis, thought to account for the IgG4-predominant plasma cells causing aortitis. Although rare, this case highlights the importance of considering IgG4-related disease (IgG4-RD) as a cause of aortitis when assessing symptomatic patients with aortic pathologies, emphasizing the complexities involved in diagnosing due to a variety of imaging presentation, differentiating, and managing large-vessel vasculitides. Moreover, it underscores the importance of Multidisciplinary Aortic Team care and the use of multiple diagnostic modalities in evaluating ambiguous aortic pathologies.

Background: Surgical approach in the treatment of thymoma is varied. This retrospective study aimed to evaluate the outcomes of different surgical approaches in the treatment of thymoma.

Methods: From January 2020 to December 2023, a total of 208 patients underwent thoracoscopic surgical treatment and were diagnosed with thymoma by postoperative pathological result in our institution. We collected and then analysed potential factors including general conditions, surgical approaches, preoperative clinical symptoms, surgical procedures, postoperative hospital stay, postoperative drainge, postoperative pain score, postoperative complications and postoperative follow-up.

Results: Of the 208 patients, 98 patients underwent surgery via subxiphoid approach (47.1%) and 110 patients via lateral intercostal approach (52.8%). The duration of the surgical procedure (P = 0.02), intraoperative blood loss (P = 0.045), total postoperative drainage (P = 0.021), postoperative drainage per day (P = 0.004) and Postoperative pain score (Day1 P = 0.010 and Day2 P = 0.002)showed a significant difference between these two groups. 31 patients (14.9%) received postoperative radiotherapy. One patient died due to postoperative radiotherapy. No recurrence occurred in one-year follow-up.

Conclusions: The present study not only showed that subxiphoid approach was a safe and feasible technique for thymoma, with a potentially faster postoperative recovery and less postoperative pain.

Hydatid cysts, caused by Echinococcus species, are zoonotic diseases frequently observed in endemic regions worldwide, including Turkey. It is most commonly localized in the liver, followed by the lungs. Anaphylaxis and peritonitis, which develop after cyst rupture, are the most significant complications observed in these patients. Early diagnosis and prompt surgical intervention are extremely important. This study presented an extremely rare case of a hepatic hydatid cyst ruptured into the thorax, which may have high morbidity and mortality. A 24-year-old male patient presented to our emergency department with cough, dyspnea, fever, and allergy symptoms. He had a history of hepatic hydatid cyst surgery 5 years ago. Physical examination revealed urticarial lesions on the skin. The body temperature was 39 °C, and the pulse rate was 120 beats/min. Laboratory tests revealed leukocytosis and elevated C-reactive protein. Contrast-enhanced thoracic and abdominal computed tomography was performed. Diagnostic tests revealed that the patient had a ruptured hepatic hydatid cyst in the right thoracic cavity; hence, he was scheduled for emergency surgery. Laparotomy was performed via a right subcostal incision, and the ruptured cyst was located. It was understood that this cyst had fistulized into the diaphragm during a chronic process and subsequently ruptured acutely into the thorax. Partial cystectomy was performed for a ruptured liver cyst. The diaphragm was repaired, and catheters were placed in the thorax and abdomen for drainage. There were no other postoperative complications. Rupture of hydatid cyst disease is frequently observed in endemic regions. The rupture of a hepatic hydatid cyst into the thorax is an extremely rare event. In patients presenting with pulmonary symptoms who have a history of hepatic hydatid cyst surgery, the abdomen should always be thoroughly evaluated, and emergency surgery should be performed if required.

Both arteriovenous malformation (AVM) and trisomy 21 are rare diseases. Studies have shown that individuals with trisomy 21 may have potential vascular malformations, with the main site of onset being the portal system. This case involved an adult patient with trisomy 21 who presented with pelvic iliac arteriovenous malformations. The patient underwent interventional treatment, and the prognosis was favorable. It is important to enhance the screening for vascular malformations in patients with trisomy 21 syndrome. At the same time, interventional treatment for AVMs is effective and increasingly important for managing AVMs.

Objective: This study aims to evaluate the long-term outcomes of compensatory hyperhidrosis (CH) after thoracoscopic sympathectomy and explore the risk factors affecting postoperative CH in primary palmar hyperhidrosis(PPH) patients.

Method: A retrospective analysis was conducted on patients who underwent thoracoscopic sympathectomy in the thoracic surgery department of our hospital from January 2015 to May 2022. Long-term follow-up surveys was conducted to collect data on post-operative satisfaction, PPH recurrence, and CH occurrence. Postoperative CH outcomes were assessed using the HDSS and satisfaction scores scale. Univariate and multivariate logistic regression analyses were used to identify independent risk factors for postoperative CH.

Result: A total of 152 patients was included in the final study, with 113 cases in the CH group and 39 cases in the nCH group. The incidence of postoperative CH was 74.3% (113/152), within which 33.6% (38/113) were severe CH. The median follow-up time was 3.1 years(2.5-5.5y) and the median interval of CH onset after surgery was 30 days (14-90d). Univariate analysis showed that body mass index(BMI), surgical time, and transected nerve level are correlated with CH, with statistically significant differences. Multivariate logistic regression analysis indicated a higher BMI (OR = 0.864, 95% CI 0.755-0.989, P < 0.05) is the independent risk factor for the occurrence of CH. There was no statistically significant difference in HDSS scores among CH patients at 1 month, 1 year, and 3 years after surgery.

Conclusion: A higher BMI is the independent risk factor for postoperative CH after thoracoscopic sympathectomy. The incidence and severity of postoperative CH kept stable during a long term follow up.

Background: Large mediastinum tumors invading the thoracic outlet have consistently been a challenge in thoracic surgery. Due to the large size of the tumor and its proximity to many important tissues, appropriate surgical approaches are crucial for a successful surgery.

Case presentations: Here, we present a case of a large neurilemmoma that invaded the thoracic outlet that was resected by a supraclavicular-median sternotomy approach. The case was a 58-year-old woman with a large mass in the right chest cavity that had invaded the thoracic outlet. The preoperative biopsy showed a blood clot with a few fibrous connective tissues covered by a single layer of flat epithelium. There was insufficient evidence to diagnose the mass as a tumor, and imaging examinations suggested a diagnosis of solitary pleural fibroma. For good exposure of the cranial and caudal aspects of the large mass, we devised a median sternotomy combined with a supraclavicular approach and safely achieved complete resection. The patient recovered well and experienced no severe complications or functional restrictions of the upper extremity. The postoperative pathology diagnosis was a neurilemmoma.

Conclusions: The supraclavicular-median sternotomy approach could be an optional approach for the complete resection of large mediastinal tumors invading the thoracic outlet.

Introduction: Infection is a significant complication of cardiac implantable electronic device (CIED) therapy. The European TauroPace™ Registry investigates the safety and efficacy of TauroPace™ (TP), an antimicrobial solution containing taurolidine, designed to prevent CIED infections.

Methods: This multicenter study included patients undergoing CIED procedures at participating centers where TP was used as a disinfectant for external hardware surfaces and an antiseptic for irrigating surgical sites. All patients eligible for CIED placement with adjunctive TP as the standard of care were included. Other aspects of CIED procedures adhered to current guidelines. Data on CIED-related infective endocarditis, CIED pocket infection, device and procedure-related complications, adverse events, and all-cause mortality were prospectively collected for 12 months. In cases of revision, the previous procedure was censored, and a new procedure was created. Binomial and Kaplan-Meier statistics were employed to analyze event rates.

Results: From January 2020 to November 2022, TP was used in 822 out of 1170 CIED procedures. Among patients who completed the 3-month follow-up, no CIED pocket infections were observed, and one case of CIED-related infective endocarditis was reported. In the 12-month follow-up cohort, two additional local pocket CIED infections were observed, resulting in a total of three major CIED infections within 1 year after the CIED placement procedure. The 3-month and 12-month major CIED infection rates were 0.125% and 0.51%, respectively. During the observation a complication rate of 4.4% was reported. No adverse events related to TP were observed.

Conclusions: TP appears to be effective and safe in preventing CIED infections.

BACKGROUNDː: Stroke, primarily resulting from ischemic conditions, is the foremost cause of mortality and long-term impairment and is frequently associated with narrowing of the carotid arteries. Although carotid endarterectomy (CEA) is the treatment of choice, it carries the risk of cerebral ischemia and reduced blood flow. Transcranial Doppler (TCD) ultrasound offers a nonintrusive method to assess cerebral blood circulation during CEA, potentially enhancing surgical outcomes. The objective of this study was to assess the clinical utility and safety of TCD monitoring during CEA and to identify factors influencing postoperative complications. METHODS: This retrospective analysis included 158 CEA patients (from January 2021-August 2023) who underwent TCD monitoring and whose data were compared to historical standard care data. The primary outcomes were operation duration and artery occlusion time. Secondary outcomes included carotid shunt usage, seven-day postoperative complications, and six-month carotid artery patency. Logistic regression identified factors linked to adverse reactions, and a predictive model was evaluated with a receiver operating characteristic (ROC) curve. RESULTSː: Comparative analysis indicated significant reductions in both the duration of surgery (113.26 ± 7.29 min) and artery occlusion time (21.85 ± 2.92 min) for patients monitored with TCD (P < 0.001) and an increase in carotid shunt implementation (25% as opposed to traditional care). The observed postoperative complications were minor, with a nonsignificant trend that favored the use of TCD-monitored procedures (1% vs. historical rates). Factors such as patient age and plaque echogenicity were found to be predictive of postoperative issues, with plaque echogenicity emerging as a significant predictive factor (OR = 10.70, 95% CI: 2.14-202, P = 0.02) upon multivariate analysis. The predictive model exhibited high precision (AUC = 0.93). CONCLUSION: This retrospective evaluation suggested that TCD monitoring in the CEA may reduce procedural time and potentially decrease postoperative complications, supporting its use for personalized surgical planning.

Objective: To explore the impact of preoperative HbA1c levels on postoperative complications in coronary heart disease patients undergoing coronary artery bypass grafting (CABG).

Methods: From September 2020 to November 2022, 98 patients with coronary heart disease who were preparing to receive CABG treatment in a cardiac surgery department of a certain hospital were included in the study using the retrospective analysis. According to the preoperative serum hemoglobin A1C (HbA1c) test results, patients were divided into a low-level group (HbA1c < 5.7%, 20 cases), a medium level group (HbA1c: 5.7% ~ 7.0%, 59 cases), and a high level group (> 7%, 19 cases). The surgical outcomes and postoperative complications among the three groups were compared.

Results: There was no statistically significant difference in the number of bypass grafts, mechanical ventilation time, and hospitalization time among the three groups of patients (P > 0.05). The high-level group stayed in the ICU longer than the other two groups, while the middle level group had a longer stay than the low-level group (P < 0.05). Within one year of postoperative follow-up, the occurrence of postoperative complications was 20.00%, 32.20%, and 47.37%, respectively, with no statistically significant difference (P > 0.05). Among them, the incidence of acute kidney injury in the high-level group was higher than that in the other groups (P < 0.05), but the correlation difference between the middle and low level groups is P > 0.05. The incidence of infection in the middle level group was higher than that in the low level group (P < 0.05), but the incidence of infection in the high and low level groups was P > 0.05 compared to the medium level group.

Conclusion: For patients with coronary heart disease undergoing CABG, the higher the preoperative HbA1c level, the longer their postoperative stay in the ICU, and the higher the risk of acute renal function damage.
