Multimodality management of focal nodular hyperplasia / A focalis nodularis hyperplasia multimodális kezelése

Focal nodular hyperplasia (FNH) is the second most common benign mass of the liver. According to the current recommendations, removal makes relative indication. Several different treatment methods are known. The purpose of the paper is to provide a summary of FNH care and to present alternative treatment options in two cases. A 40-year old woman was investigated for abdominal complaints; CT scan confirmed FNH of the liver. Given the localization of the lesion, we chose transarterial embolization (TAE) due to the high risk of surgical resection. After multiple treatments, regression was achieved, and the patient became asymptomatic. Painful FNH in a 25-year-old female was confirmed by MRI. The lesion was dominantly seen in segment 1, causing vena cava compression and collaptiform episodes. As a definitive solution, liver resection was performed, after which her complaints ceased. Long-term follow-up of patients may be sufficient when asymptomatic FNH is detected. In the case of symptoms or high risk of surgery, TAE can be used effectively by FNH either alone or in combination with surgical treatment. For lower-risk patients, primary laparoscopic resection is the most appropriate choice.

[Decreasing morbidity after Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) with technical modification and patient selection]. / Speciális májmutét (Associating Liver Partition and Portal vein ligation for Staged hepatectomy, ALPPS) morbiditásának csökkentése átértékelt betegkiválasztási elvek és mutéttechnikai módosítás révén.

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.

New method for treatment of inferior vena cava tumor thrombus ­ case study.

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.

[ALPPS (Associated Liver Partition and Portal vein ligation for Staged hepatectomy) -- faster and greater growth of liver]. / ALPPS (Associated Liver Partition and Portal vein ligation for staged hepatectomy) -- gyorsabb, nagyobb májhypertrophia.

CASE REPORT: 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.

[Prognosis and classification of hypertensive striatocapsular haemorrhages]. / A hypertoniás eredetu striatocapsularis agyvérzések felosztása és prognózisa.

INTRODUCTION: Nontraumatic intracerebral haemorrhage accounts for 10 to 15% of all cases of stroke. PATIENTS AND METHOD: In our study hypertensive striatocapsular haemorrhages were divided into six types on the basis of arterial territories: posterolateral, lateral, posteromedial, middle, anterior and massive (where the origin of the hemorrhage can not be defined due to the extensive damage of the striatocapsular region) type. We analysed laboratory data, clinical presentations and risk factors as alcoholism, smoking and hypertension of 111 cases. The size of the hematoma, midline shift and severity of ventricular propagation were measured on the acute CT-scan. The effect on the 30-day clinical outcome of these parameters were examined. RESULTS AND CONCLUSION: According to our results, the most important risk factor of hypertensive intracerebral haemorrhage was chronic alcoholism. Blood cholesterol, triglyceride levels and coagulation status had no effect on the prognosis, but high blood glucose levels significantly worsen the clinical outcome. In our study, lateral striatocapsular haemorrhage was the most common while middle one was the least common type. The overall mortality is 42%, but differs by the type. The 30-day outcome significantly depends on the type of the haemorrhage, the initial level of consciousness, the size of the haematoma, the severity of ventricular propagation, the midline shift and the blood glucose levels. The clinical outcome proved to be the best in the anterior type, good in the posteromedial and lateral types. The prognosis of the massive type is poor. In our study, the classes and the mortality of the striatocapsular haemorrhages was different from the literature data. The higher mortality in our cohort could be due to the longer follow-up and the severe accompanying diseases of our patients.

[Cerebellar venous anomalies with symptomatic vascular malformations]. / Idegrendszeri tüneteket okozó vascularis malformatiókkal társult cerebellaris vénás anomáliák.

Cerebral and cerebellar venous anomalies (previously known as venous angiomas) form the alternative venous drainage of the surrounding nervous tissue because of the un-development of the normal venous system. They are made up of veins with abnormal structure: thick walls, lumens dilated and of irregular calibre that converge radially towards a wide draining vein (caput medusae). They are thought to be a benign condition although they are sometimes associated with cerebellar hemorrhages. Authors report three patients with cerebellar venous anomalies associated either with pontine cavernoma, cerebellar arteriovenous malformation or cerebellar infarct. They illustrate that cerebellar venous anomalies are benign conditions, but their presence might be a marker for additional, pathogenic malformation. It might be difficult to detect the associated malformations even by sophisticated imaging methods, but their presence can modify the treatment options.

[Role of extra-anatomical bypasses in the treatment of aorto-iliac occlusion]. / Az extraanatomicus áthidalások szerepe az aortoiliacalis veróér elzáródás kezelésében.

In the last six years we have performed 468 operations because of aortoiliac occlusion or septic complications of these arteries. 410 (87.6%) of these operations were anatomical reconstructions, in 58 (12.4%) patients we performed extra anatomical bypasses. The distribution of the operations was the following; 12 obturator, 23 femoro-femoral crossover, 13 axillofemoral and 10 axillobifemoral bypasses. The indication for extra-anatomical reconstruction in 24 (41.4%) patients was septic complication (EABS), and in 34 cases (58.6%) poor general condition or difficulties during surgery. The average age of the patients with non-septic indication (EABNS) was significantly higher than the average age of the patients treated with anatomical reconstruction (AR) (66.3 vs. 60.9 year, p < 0.01). There were more REDO operations in the group EABNS then in the AR group (35.3%/11.7% p < 0.02). Despite of the high operative risk, the rate of early complications (EABNS 13.8%, AR 10%) and postoperative mortality (EABNS 3.7%, AR 4.0%) was not statistically different between the two groups. If the indication was aorto-duodenal fistula (6 patients) or acute limb ischaemia (7 patients), the mortality was significantly higher compared to other extra-anatomical operations (46.2% vs. 4.4%, p < 0.01). The postoperative mortality after EABNS and EABS operations was similar (11.7% vs. 16.6%), but we performed more reoperations after EABS operations (10/24 vs. 2/34, p < 0.05). According to our early postoperative results elective extra-anatomical bypasses are suitable for the treatment of aortoiliac occlusion in high risk patients, with poor life expectancy. Extra-anatomical bypasses are performed because of acute ischemia or septic complications which are life or limb threatening complications, so early results must be validated concerning this fact.
