Regionale intraarterielle Chemotherapie mit Dacarbazin bei isolierten Lebermetastasen eines malignen Melanoms

2008

A 58-year-old woman underwent regional intra-arterial chemotherapy for hepatic metastases of a malignant melanoma, because at the time no other organ metastasis was demonstrable. Dacarbazine was injected as a bolus on five successive days, four weeks apart, after which there were several days of fever and the urinary melanogen test became positive. At first the patient clearly improved and was again able to walk. But four months after the start of treatment she died in a hepatic coma.

Regional hypothermia of the kidney: surface or transarterial perfusion cooling? A functional study.

1980

Hypothermia reduces ischemic damage if prolonged occlusion of the renal artery is required during an in situ kidney operation. Hypothermia may be achieved by external cooling or by transarterial hypothermic perfusion. External cooling may lower intrarenal temperature heterogeneously. Perfusion techniques via intra-arterial catheters introduced percutaneously are associated with minimal technical difficulties. The 95 patients who underwent extensive hypothermic nephrolithotomy had differential 131iodine hippuran clearance studies preoperatively, and 2 weeks and 6 to 46 months postoperatively. Sixty-three kidneys were cooled by transarterial hypothermic perfusion and 39 were cooled with topic…

RELATIONSHIP BETWEEN OBESITY AND LEFT VENTRICULAR MASS IN CAUCASIAN HYPERTENSIVE SUBJECTS. DOES SEX MATTER?

2015

Objective The excess of adiposity affects the heart through haemodynamic and non haemodynamic mechanisms leading to left ventricular hypertrophy (LVH) and ultimately to heart failure. It has been been previously observed, in a large study performed in American Indians, that the impact of obesity on left ventricular mass (LVM) is greater in women than men, while the results of other investigations carried out in other ethnic groups have yielded conflicting results .The aim of our study was to evaluate the potential influence of gender on the relationships between obesity and LVM in Caucasian patients with essential hypertension (EHs) . Design and method We enrolled 724 subjects with EH (mean…

High-intensity transient signals during laparoscopic surgery in children.

2009

Background Laparoscopic interventions in children gain increasing popularity. Pneumoperitoneum as applied during laparoscopic surgery can induce gas emboli formation, but it is unclear whether this is associated with cerebral embolic events. To investigate the hypothesis that pneumoperitoneum causes cerebral emboli in children, the number and intensity of high-intensity transient signals (HITS) detected using transcranial Doppler ultrasonography were assessed before and after induction of pneumoperitoneum. Methods Twenty children were monitored during laparoscopic surgery. General anaesthesia was performed using sevoflurane and sufentanil or alfentanil. Pressure-controlled ventilation was a…

Implementation of laser speckle contrast analysis as connection kit for mobile phone for assessment of skin blood flow

2014

Laser speckle contrast analysis (LASCA) offers a non-contact, full-field, and real-time mapping of capillary blood flow and can be considered as an alternative method to Laser Doppler perfusion imaging. LASCA technique has been implemented in several commercial instruments. However, these systems are still too expensive and bulky to be widely available. Several optical techniques have found new implementations as connection kits for mobile phones thus offering low cost screening devices. In this work we demonstrate simple implementation of LASCA imaging technique as connection kit for mobile phone for primary low-cost assessment of skin blood flow. Stabilized 650 nm and 532 nm laser diode m…

Variant Arterial Supply of the Descending Colon by the Coeliac Trunk: A Case Report

2021

Background and Objectives: Knowledge of arterial variations of the intestines is of great importance in visceral surgery and interventional radiology. Materials and Methods: An unusual variation in the blood supply of the descending colon was observed in a Caucasian female body donor. Results: In this case, the left colic artery that regularly derives from the inferior mesenteric artery supplying the descending colon was instead a branch of the common hepatic artery. Conclusions: Here, we describe the very rare case of an aberrant left colic artery arising from the common hepatic artery in a dissection study.

Efficacy of intra-arterial lidocaine infusion in the treatment of cerulein-induced acute pancreatitis

2020

Background Disturbances in pancreatic microcirculation, beginning with vasoconstriction, are crucial in early pancreatitis and progression to necrotizing pancreatitis. Thus, vascular-targeted treatment aiming to restore a sufficient level of microcirculation through vasodilation would possibly reduce the severity of pancreatitis. Lidocaine is an anti-arrhythmic and local anesthetic drug, which also acts as a vasodilator at higher concentrations. Objectives To evaluate the efficacy of intra-arterial infusion of lidocaine into the celiac trunk in treatment of cerulein-induced acute pancreatitis. Material and methods Wistar rats (n = 20) were randomly divided into 2 equal groups: the control g…

Recalibrating survival prediction among patients receiving trans‐arterial chemoembolization for hepatocellular carcinoma

2021

Background & Aims The Pre-TACE-Predict model was devised to assess prognosis of patients treated with trans-arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). However, before entering clinical practice, a model should demonstrate that it performs a useful role. Methods We performed an independent external validation of the Pre-TACE model in a cohort that differs in setting and time period from the one that generated the original model. Data from 826 patients treated with TACE for naïve HCC (2008-2018) were used to assess calibration and discrimination of the Pre-TACE-Predict model. Results The four risk-categories identified by the Pre-TACE-Predict model had gradient …
