The Authors experience in the surgical treatment of varicose veins of the lower limbs in the last 15 years, performed on 1500 cases, show that varicose recurrence may be nearly always attributed to unrecognised anatomical variations in the venous system. Methods of preoperative and intraoperative diagnosis are described and the most frequent variants observed are presented and their significance are discussed.

The aim of the investigation was to study the morphological condition of blood cells in the basins of the ischemic limbs and their dynamics as a result of various types of surgical treatment. Implementation of combined surgical treatment has a more normalizing effect in comparison with isolated reconstructive surgical treatment. The use of lumbar sympathectomy in patients with occlusive lesions of arteries of lower limbs and varying degrees of ischemia reduces endothelial dysfunction and normalizes a number of parameters describing the morphology and functioning of red blood cells and platelets. There was detected the deformation of red blood cells indicating that the restoration of the plasticity of red blood cell membranes significally reduced the degree of agglutination of red blood cells. According to obtained data the influence of sympathectomy depends on the severity of the disease in general the highest efficiency is observed at the II and III degree of ischemia.

The incidence of urolithiasis is progressively increasing worldwide, as is the surgical treatment of urinary stones. The most frequent surgery for urolithiasis is ureterorenoscopy, which is performed in the lithotomy position. This position is also used in the endoscopic approach to bladder stones. Lateral decubitus is rarely used in the treatment of urinary stones. In the case of complex kidney stones, the gold standard treatment is percutaneous nephrolithotomy. This surgery has traditionally been performed in the prone position. However, the use of the supine (Valdivia) position is increasing in recent times. Furthermore, the Galdakao-modified supine Valdivia position has been widely used for percutaneous nephrolithotomy since it was described by Ibarluzea et al. in 2007. Treatment of kidney and ureteral stones simultaneously is allowed in both supine positions. In addition, they allow the removal of encrusted stents and the easy placement of double J stents and, in the case of the Galdakao-modified supine Valdivia position, percutaneous nephrostomies. Compartment syndrome is a rare complication in the lithotomy position, but scarcely described in the supine position. This especially applies to the Galdakao-modified supine Valdivia position, in which the lower limbs are in moderate flexion, with the ipsilateral lower limb in a slightly lower position relative to the other. This complication can lead to skin necrosis, myoglobinuric renal failure, amputation, permanent neuromuscular dysfunction, and even death. Risk factors include Body Mass Index, male gender, obesity, increased muscle mass, peripheral vascular disease (advanced age, hypertension, hyperlipidemia and diabetes mellitus), height, lack of operative experience, significant bleeding during surgery, hypothermia, acidemia, combination general-spinal anesthesia, prolonged surgical time, systemic hypotension, ASA (American Society of Anesthesiologists) class or vasoconstrictor drugs. Therefore, compartment syndrome of the leg is a potentially devastating complication that must be suspected and treated through early decompression of the compartment by four compartment fasciotomy. Preventive measures reduce the incidence of this condition.

The aim of the study was features of ultrastructural changes in cellular elements and connective tissue carcass of the great saphenous vein (GSV) at varicose disease in depending on the duration of the disease in persons of different ages. An examination by light microscopy of 133 fragments of BPV, excised during phlebectomy in 19 patients, and an electron microscopic examination of 532 preparations were performed. Depending on the age of the patients, four age groups was distinguished: 18-44 years old (young people); 45-59 years (middle-aged people); 60-74 years old (the elderly), 75-90 years old (persons of senile age). In the wall of the GSV of young people with a small duration of the disease, there were poorly expressed pathomorphological changes characterized by moderately expressed endothelial dysfunction and minor hypertrophy of smooth muscle cells (SMC) of the middle shell. In the group of middle-aged people, in addition to age-related changes in the structure of the wall of varicose dilated GSV, pathological changes are noted that are characteristic of the long course of the disease with the development of endothelial dysfunction. The phenotypic heterogeneity of the SMC in the middle shell intensifies, and the communication links between them is altered. Disorganization of connective tissue leads to a decrease in the strength of the connective tissue vein skeleton. Hypertrophy of SMC, as a universal compensatory-adaptive response of cells, develops in response to an increase in functional load with hemodynamic disturbances in the veins of the lower limbs and to compensate for the quantitative deficiency of SMC as a result of their death. In elderly and senile age the duration of varicose disease is more than 10 years, on average - up to 25-30 years. The number of destructively altered SMC is increasing, degenerative processes and sclerotic changes are progressing. The ultrastructural analysis of biopsies showed that at the initial stage of development of varicose disease in young people with a small duration of varicose disease, morphological changes in the structure of the GSV wall are poorly expressed. With the increase in the age of the patient and the duration of the disease, changes in GSV are progressed. Involute degenerative-dystrophic changes are most pronounced in patients over 60 years of age and are an aggravating factor during varicose transformation of the GSV wall. In elderly and senile age, the compensatory possibilities of the cells decrease, the sclerotic degenerative changes in the wall of the GSV are progressed.
