Background: Cardiac paragangliomas are rare neuroendocrine tumors that will cause significant morbidity if left undiagnosed. Because of the paucity of cohort data, their rapid diagnosis and appropriate management still pose unique challenges to cardiac surgeons. We aimed to investigate the clinical features and surgical management of primary cardiac paragangliomas in our single center. Methods: From May 2014 to October 2020, patients diagnosed with primary cardiac paragangliomas retrospectively were reviewed. Demographic data, clinical presentation, preoperative imaging methods, surgical resection, perioperative management, histological analysis, and outcomes were recorded. Postoperative follow up also was reviewed. Results: With multiple imaging methods, including echocardiography, computed tomography, positron-emission tomographic-computed tomography, and biochemical tests, there were five cases of primary cardiac paraganglioma verified by postoperative immunohistochemical staining, two of which were hormonally active. There were no metastatic cardiac paragangliomas, according to positron-emission tomographic-computed tomography, and all patients accepted surgical treatment. Preoperative adrenoceptor blockade was given to hormonally active patients, accordingly. Complete resection of the tumor was accomplished under cardiopulmonary bypass in each case. Tumor distribution included two masses on the roof of the left atrium, two masses in the right atrioventricular groove, and one between the ascending aorta and main pulmonary artery. Immunohistochemical staining for chromogranin, neuron-specific enolase, synaptophysin, and S-100 were positive, which were typical of cardiac paraganglioma. There were no operative deaths. All the patients had an uneventful recovery except one patient who underwent low cardiac output syndrome. During follow up (mean 4.2 years, range 0.6-7.0 years), all patients were well with New York Heart Association class I or II. Only one patient developed thyroid carcinoma three years after surgery but with no paraganglioma recurrence during periodic computed tomography, and this patient recovered well after thyroidectomy. Conclusion: Although cardiac paragangliomas are rare and may present surgical challenges for clinicians, surgical resection remains the choice of treatment with favorable outcomes through a multidisciplinary heart team. Moreover, lifelong surveillance still is recommended to detect possible recurrence or associated nonchromaffin tumors in time.

Hepatocellular carcinoma (HCC) is a highly malignant tumor with a poor prognosis and an annual incidence of between 250,000 and 1.2 million cases in high risk areas, such as Southeast Asia, coastal areas of mainland China, and sub-Saharan Africa. Worldwide, it is the seventh most common cancer with the highest incidence of adult malignancy in areas endemic for then hepatitis B virus. From a clinical point of view, the number of HCC cases in Switzerland is expected to possibly increase, due to the increasing number of patients with chronic hepatitis C. The only established treatment to cure the HCC involves hepatic resection or, in selected cases, transplantation. However, the success of these operations is frequently limited due to the often-advanced stage of the tumor at the time of diagnosis. Recent advances in techniques of liver surgery, better preoperative imaging methods and therefore better patient selection have helped to lower mortality and morbidity after hepatic resection. The most frequently used imaging methods today, CT-scan and dynamic CT-scan, may be replaced by the MRI in the near future because of it's more detailed and more sensitive image of liver tumours. A still unresolved problem is the possibly life-threatening postoperative liver insufficiency caused by poor or insufficient liver remnant tissue which may occur after even limited liver resection especially in cirrhotic livers. A prevention of this problem would require a reliable preoperative assessment of the functional capacity of the liver remnant. But these functional assessments are still not satisfactory although the aminopyrin breathing test and galactose eliminating capacity test achieve remarkably good results. The clinical experience of important series of liver resection reported in this issue of Swiss Surgery for HCC from Switzerland, liver resection for HCC in cirrhotic patients from China as well as liver resection for cholangiocellular carcinomas demonstrate that the surgical procedures performed by experts today have a low mortality and morbidity rate and achieve quite remarkable long term survival results. As surgeons and physicians alike we are therefore encouraged today to resect these HCC whenever technically possible and whenever the clinical condition of the patients allow these operations.

Abstract. Background: After carotid artery stenting (CAS), neurological complications that cannot be explained with imaging methods may develop. In our study we aimed to show, using oxidative stress markers, isolated oxidative damage and resulting neurological findings following CAS in patients with asymptomatic carotid artery stenosis. Patients and methods: We included 131 neurologically asymptomatic patients requiring CAS. The neurological findings were evaluated using the modified Rankin Scale (mRS) prior to the procedure, one hour post-procedure, and two days after. Patients with elevated mRS scores but with or without typical hyperintense lesions observed on an MRI and with changes of oxidative stress marker levels at the time (Δtotal-thiol, Δtotal antioxidative status [TAS], and Δtotal oxidant status [TOS]) were evaluated. Results: In the neurological examination carried out one hour prior to the procedure, there were 92 patients with mRS = 0, 20 with mRS = 1, and 12 with mRS = 2. When Δtotal-thiol, ΔTAS, and ΔTOS values and the mRS were compared, it was observed that as the difference in oxidative parameters increased, clinical deterioration also increased proportionally (p = 0.001). Conclusions: We demonstrate a possible correlation between oxidative damage and neurological findings after CAS which could not be explained by routine imaging methods.
