Westergren Method

The Westergren method (a. Westergren; Swedish. W. A. ​​Westergrén; 1886–1972) is one of the methods for assessing the effectiveness of tuberculosis treatment. This method was developed at the beginning of the 20th century by the Swedish physician Alfred Westergrén (1877–1963).

The Westergren method is based on determining the number of tuberculosis bacilli in the patient’s sputum and comparing them with the norm. The normal number of rods is no more than 40 in the field of view of the microscope. If the number of sticks exceeds the norm, then this indicates the ineffectiveness of the treatment.

A microscope is used to determine the number of tuberculosis bacilli. After collecting sputum, it is placed on a glass slide and examined under a microscope. The number of tuberculosis bacilli is assessed in the field of view, which is 100 microns.

The Westergren method is one of the most common methods for evaluating the treatment of pulmonary tuberculosis. It allows you to quickly and accurately determine the effectiveness of treatment, which allows you to take timely measures to improve its results.

Westergren - a method of surgical treatment of aneurysm of the abdominal aorta and its branches. Developed by the Swedish surgeon Anders Westergren, he contributed to the introduction of microsurgical techniques into the practice of surgical treatment. Based on the separation of the common iliac artery from the abdominal aorta above the renal arteries to prevent embolism and ischemia of the lower half of the body and abdominal cavity after operations on the aorta and abdominal arteries. Combines methods of direct patching of aneurysms and resection of the affected area of ​​the artery with vascular-sparing plastic surgery. Mainly used for arteriomesenchymal aneurysms. Anastomoses are performed using the main vascular suture or by using microsurgery methods. According to a number of authors, the incidence of complications when using the Westergran method is less than 0.5%. This method is considered an effective and safe method for treating arterial aneurysms, especially those that cannot be operated on with the traditional open method.
