[Distant pulse-wave lithotripsy in the Central Clinical Air Force Hospital ].

With participation of the specialists from the 7th Central Military Clinical Aviation Hospital 4 pulse-wave complexes "Urat-P", "Urat-P2", "Ulitho", "Cholelithotriptor" were developed and introduced into clinical practice of the hospital. Distant pulse-wave lithotripsy was conducted 3035 patients (358 persons from flying staff). It is the main method of urolithiasis treatment, especially in the flying staff. Its efficiency is more than 96%. The modern models of lithotriptors are effective in destruction of biliary and urinary calculi and the applied parameters of wave impulses don't impact on the organs and tissues. The sphere of use of pulse-wave effect in the clinical practice was extended.

[Laparoscopic cholecystectomy in the treatment, rehabilitation and clinical health certification of the flying personnel with cholelithiasis].

Applicability of laparoscopic cholecystectomy (LSCE), a modern approach to the treatment of cholelithiasis, to rehabilitation, and military medical and military aviation certification was evaluated. Since 1994, 303 LSCE operations, including to 97 patients-aviators, have been performed by way of penetrating the abdominal wall with a standard laporoscopic stand (K-Chtorz, Germany). After introduction of LSCE, only 9 operations (2.9%) were fulfilled with the conventional technique. Immediate results of treatment of aviators were satisfactory and characterized by a good cosmetic effect, more rapid recovery of the motor activity, minimal complications (2.2%), absence of severe post-operational pancreatic/biliary dysfunctions, and expedited course of treatment.

[Lumbar sympathectomy in atherosclerosis obliterance of lower limb arteries and age of the patients].

In the elderly and old patients with atherosclerosis of lower limb arteries, ultrasonic dopplerography assisted study of hemodynamics in foot with use of Valsalva and corinfar tests was carried out. It is revealed that these patients retain high reaction to sympathetic influences. The obtained data were the base for use of lumbar sympathectomy in 419 patients over 65 years as an independent method of surgical treatment and in combination with reconstructive operations on major arteries. Good results were obtained in 70.1% operated patients, satisfactory results--in 22.7%. There were no significant differences in the results of lumbar sympathectomy between this age group and younger patients.

[Current approaches to the diagnosis, treatment and expertise of cholelithiasis in pilots].

Data on the modern mechanisms of forming the cholelithiasis and the new methods of its treatment are presented. There have been examined 337 pilots of the helicopter aviation with the professional length of service of 10 year and more, the cholelithiasis has been revealed in 107 cases. In the course of treatment there have been used the preparations of ursodeoxycholic acid (urosan), remote shock-wave lithotripsy and laparoscopic cholecystectomy. There is demonstrated the high efficiency of these methods during examination of 106 patients who after passing the air-force medical board are pronounced for proceeding their flying activity.

[The work experience of the Central Military Aviation Research Hospital in the occupational rehabilitation of flight personnel after lithotripsy].

The evolution of the domestic-certified lithotriptors has made a complete professional rehabilitation of all pilots (100%) suffered from urolithiasis without operative intervention possible. Of 156 pilots who have been exposed to remote shock-wave lithotripsy (RSWL) in recent three years 120 individuals (93%) had the urate stones in the renal calyces. Before introducing the RSWL in clinical practice such concrement were recognized as inoperable and the urolithic pilots have no prospects for continuation of their flying activities. After the RSWL application there was a decrease in the secretory-excretory renal function due to the disturbed urodynamics by the migratory fragments of crushed stones in the renal system. The recovery of renal function occurred after complete passage of the crushed stone fragments. Depending on the composition of a crushed concrement, severity of inflammatory process taking place in the kidneys and urinary tracts, the special program of countermeasures to prevent relapsed lithogenesis was recommended for use by the patients. The relapse of renal stone formation after RSWL application was noted in 4 (3.2%) pilots. In these pilots, the concrements were recrushed by the mentioned method and professional qualification of above individuals was retained. Until recently, the treatment of cholelithic disease was recognized as a purely surgical problem--with the introduction of RSWL of renal stone into clinical practice there appeared real possibility to apply the similar approach to crushing the gallstones. To attain these ends, the experimental studies with the use of lithotriptor "URAT-P" have been performed. 140 gallstones of 0.5 to 2.0 cm in size were crushed. The parameters of shock waves are determined.(ABSTRACT TRUNCATED AT 250 WORDS)

[Current problems in the diagnosis, treatment and prevention of cholelithiasis in flight personnel].

In 50% of afflicted pilots, cholelithiasis is asymptotic and develops with the minimum anatomicomorphological changes of the biliary system. An early diagnostics of cholelithiasis in the pilots will enable one to treat them timely with the aim of returning the pilots to flying activity in the future. The introduction of nonsurgical treatment methods into the clinical practice with an application of distance shock-wave cholelithotripsy will elevate the percentage of pilots returning to flying activities. A need for developing domestic special devices for cholelithotripsy is ripe.

[Early thrombotic complications after femoro-popliteal segment surgery].

The work analyses the causes of early postoperative thromboses which occurred after reconstructive operations on the femoro-popliteal segment in 293 patients. Early postoperative thromboses are a frequent complication in reconstructive operations on the vessels and develop in 27% of cases mostly in the first days after the operation. The most frequent causes of early thromboses were deficient distal arterial blood circulation, technical and tactical errors of the intervention, and insufficiently corrected postoperative therapy. It is pointed out that combination of reconstructive operations on the main vessels with lumbar gangliectomy has a favorable effect on the results of treatment and prevention of early thromboses. The use of microsurgical techniques reduces the probability of the development of early postoperative thromboses. In the absence of an effect of repeated operative interventions, in increase of ischemia and intoxication the limb must be amputated before gangrene develops.
