Catheter-directed thrombolysis is not limited to acute limb ischemia treatment: experience from a division of vascular surgery.

Background: Thrombolytic treatment has many potential indications in the era of modern vascular surgery. We aimed to analyze the contemporary experience in the catheter-directed, intraarterial thrombolysis in different clinical scenarios.

Methods: The available data of 121 patients with different types (acute, subacute, complications of vascular procedures) of lower limb ischemia treated by means of the intraarterial, catheter-directed thrombolysis between November 2011 and December 2016 were retrospectively analyzed.

Quantitative anatomy of the growing clavicle in the human fetus: CT, digital image analysis, and statistical study.

Purposes: Knowledge of dimensions of fetal long bones is useful in both the assessment of fetal growth and early detection of inherited defects. Measurements of the fetal clavicle may facilitate detection of numerous defects, e.g.

The normal growth of the tracheal wall in human foetuses.

Introduction: Tracheal wall thickness is a substantial indicator in various pathological changes. The present study was performed to compile normative data and formulae for the tracheal wall thickness and volume at varying gestational age.

Material And Methods: Using anatomical dissection, digital image analysis and statistics a range of the wall thickness, proximal internal-to-external cross-sectional area ratio, and wall volume for the trachea in 73 spontaneously aborted human fetuses aged 14-25 weeks was examined.

Tracheo-bronchial angles in the human fetus -- an anatomical, digital, and statistical study.

Background: Both the advancement of visual techniques and intensive progress in perinatal medicine result in performing airway management in the fetus and neonate affected by life-threatening malformations. This study aimed to examine the 3 tracheo-bronchial angles, including the right and left bronchial angles, and the interbronchial angle, in the fetus at various gestational ages.

Material And Methods: Using methods of anatomical dissection, digital image analysis with an adequate program (NIS-Elements BR 3.

Novel patterns for the growing main bronchi in the human fetus: an anatomical, digital and statistical study.

Purpose: Intensive progress in prenatal medicine results in performing airway management in the fetus affected by life-threatening congenital malformations. This study aimed to examine age-specific reference intervals and growth dynamics for length, proximal and distal external transverse diameters, and projection surface areas of the two main bronchi at varying gestational ages, including their relative growth in length and projection surface area.

Materials And Methods: Using anatomical dissection, digital image analysis and statistics, length, proximal and distal external transverse diameters, and projection surface areas of the right and left main bronchi were examined in 73 human fetuses (39 males, 34 females) aged 14-25 weeks, derived from spontaneous abortions and stillbirths.

The normal growth of cross-sectional areas of the aorto-iliac segment in human fetuses - an anatomical, digital, and statistical study.

Background: The intraluminal size of the aorto-iliac segment is relevant in both the clinical and echographic settings. The aim of this study was to compile both the absolute and relative age-specific reference intervals for cross-sectional areas (CSAs) of the aorto-iliac segment.

Material/methods: Using the methods of anatomical dissection, digital-image analysis (Leica QWin Pro 16) and statistical analysis (Student's t test, one-way ANOVA, post-hoc RIR Tukey test, linear regression), the growth in CSA (in mm2) of the abdominal aorta, the common, external, and internal iliac arteries in 124 (60 males, 64 females) spontaneously aborted human fetuses aged 15-34 weeks was examined.

The retroperitoneal anastomoses of the gonadal veins in human foetuses.

In the retroperitoneal space the gonadal veins form a collateral circulation that has a great clinical impact on sclerotherapy or surgical ligation of varicoceles. The aim of this study was to examine the communications of the gonadal veins (according to classification, frequency of appearance, gender and syntopic differences) in human foetuses of both sexes (71 males and 59 females) aged 4--6 months of intrauterine life. On the right side the most frequently were found the gonadal-periureteral anastomosis (23%) and the gonadal-perirenal anastomosis (22%).

Morphometry of the pancreas in human foetuses.

With the use of conventional anatomical dissection, radiography, digital and statistical analysis, morphometry and skeletopy of the pancreas was carried out in 60 human foetuses of both sexes (28 female, 32 male) between the 17th and 40th week of intrauterine life. The material was fixed in a 10% formalin solution. The age of the foetuses was determined by crown-rump (CR) length measurement on the basis of the Iffy et al.

Perforating veins of the shin in human foetuses.

There are 3 groups of perforating veins of the shin: the medial, the lateral and the internal sural perforating veins. Dysfunction of these veins is one of the main factors in venous hypertension. There is a lack of data in the literature concerning perforating veins of the shin in human foetuses.

The pancreaticoduodenal arteries in human foetal development.

Knowledge of the course of the pancreaticoduodenal arteries is of great importance in pancreatic surgery. Lack of care in the preparation of these vessels may lead to ischaemia or necrosis of the duodenum, the first loop of the jejunum, the head of the pancreas and even the liver, bile ducts and transverse colon. In such events, the surgeon would need to diagnose the course of the vessels and their anastomoses intraoperatively.

The cystic artery in human foetuses.

The cystic artery varies in origin, course and number and it is important to recognise it during operative procedure. Insufficient recognition of its anatomical variation may contribute to a dangerous situation, especially during laparoscopic cholecystectomy. To prevent iatrogenic injuries of the vessels and bile ducts, correct preparation with clear identification of the anatomic structures is essential.
