Conventional surgical therapy for advanced renal venous tumor thrombi results in high morbidity, so there is a need for less invasive techniques. This report presents the first case of a successful inferior vena cava (IVC) tumor thrombus removal without complications with balloon catheter (BC) via internal jugular vein (IJV), called the venous tumor thrombus pushing with balloon catheter (VTTP BC). Under the control of transesophageal echocardiogram and fluoroscope, a balloon catheter was sleeved on the guide wire, which was already inserted into the right internal jugular vein (IJV) and was driven distally above the IVC tumor thrombus. The balloon was inflated to occlude the IVC for prevention of pulmonary embolization. After the occlusion, the guide wire was driven to the cavotomy and was opened at the ostium of the right renal vein. It was pulled at both ends and stretched to serve as a rail. The balloon was gently pushed toward the cavotomy and the thrombectomy was completed. This is a less invasive method for treatment of venous tumor thrombus level 3 that can reduce surgical time, blood loss, and complication rates compared to the existing surgical methods. Also, it can be performed without thoracotomy, cardiopulmonary bypass, hypothermic circulatory arrest, and liver mobilization.

Cerebellar developmental venous anomalies (CDVA) are benign conditions, although sometimes they are associated with haemorrhages and reported to be symptomatic. This is the largest follow-up study to investigate the symptomatology of CDVAs and their association with other malformations. Thirty-two patients were followed for 2 - 9 years. Twenty-eight had isolated asymptomatic CDVA without any neurological condition during follow-up, which might be linked to the CDVA. Four patients had CDVA and an associated vascular pathology: two pontine cavernomas, one asymptomatic arteriovenous malformation (this is the first published case in the literature) and one cerebellar infarct with a developmental variation of the posterior fossa venous circulation. One patient had two CDVAs, while another had a unique draining vein from the upper part of the brainstem too. In conclusion, CDVAs are benign, asymptomatic conditions, but they are sometimes associated with pathogenic malformations requiring detailed neuroradiological investigations.

75 years old female patient was referred with large, multifocal colorectal liver metastasis. Prior to this consultation she received chemotherapies of various protocols and series. Liver metastasis, however, increased at about 3 times of the original size during the 5 months of the oncological treatment. A right extended hepatectomy was planned to remove the tumor, but the residual liver (FLR) was found to be too small. Portal occlusion technique was necessary to induce the hypertrophy of the FLR. Due to rapid tumor progression we decided to perform the first ALPPS (PVL + in situ split) procedure in Hungary. After a very fast (9 days) and significant (94%) hypertrophy of the FLR the planned liver resection was successfully performed.

Introduction: Resecability of liver tumors is exclusively depending on the future liver remnant (FLR). The remnant can be hypertrophised using portal vein occlusion techniques. The latest hypertrophising method is Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS), which provides the most significant induced hypertrophy in the shortest time. Morbidity and mortality of this procedure were initially unacceptably high. Aim: Reducing complications by better patient selection and modified surgical technique. Method: The First Department of Surgery, Semmelweis University, Budapest, prefers the ‘no touch’ technique, instead of ‘complete mobilization’. For optimizing patient selection, an international registry (including our patients’ data) was established. In addition to the surgical, we collected demographic, disease, liver function, histology, morbidity (Clavien–Dindo) and mortality parameters. Volume and function measurements were performed by using CT-volumetry and 99mtechnecium-mebrofenin SPECT/CT. Data were analyzed by multivariate analysis (significance: p<0.05). Results: We performed 20 ALPPS procedures from 2012 to 2018. The relative volume increment and resectability in our department and among the 320 registry patients were 96% vs. 86% and 95% vs. 98%. Using ‘no touch’ technique, the Clavien–Dindo III–IV morbidity and mortality rates were significantly lower (22%–0%) than with ‘complete mobilization’ (63%–36%) (p<0.05). Based on the multivariate analysis of the registry patients, age over 60 years, liver macrosteatosis, non-colorectal liver tumor, >300 minutes operation time, >2 units of red blood cell transfusion, or insufficient FLR function before stage 2 were identified as independent factors influencing mortality (p<0.05). Conclusion: Mortality and morbidity of ALPPS can be reduced by proper patient selection and ‘no touch’ surgical technique. Orv Hetil. 2019; 160(32): 1260–1269.

Recurrence was greater with T3/4 disease compared to T1/2 disease (70% versus 60%) (p = 0.01). T1/2 disease in the <75 group was associated with fewer recurrences than <75 T3/4 disease group (p 0.001). Recurrence rates were comparable with T1/T2 disease and T3/T4 disease in the >75 years group (p = 0.190). There was no improvement in DFS with and without AC following hepatectomy in the >75 group (p = 0.161). However there was improved DFS between the <75 groups with AC and without AC (p 0.001). OS in the>75 group was improved in the group receiving AC compared to the >75 group not receiving AC (p = 0.023). Conclusions: In patients with CRLM, with advancing age, recurrence rates do not seem to be affected by the T stage. In addition, AC following hepatectomy does not appear to improve DFS survival with advancing age.
