[Surgery of abdominal aorta occlusion]

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Surgical Pathology

Background:

• Aortic occlusions present complex surgical challenges.
• Effective treatment strategies require precise classification and tailored surgical approaches.

Purpose of the Study:

• To present surgical experience in treating aortic occlusions.
• To introduce a novel pathomorphological classification for aortic occlusions.
• To guide the selection of surgical operations and access based on classification.

Main Methods:

• Retrospective analysis of 325 patients undergoing surgical treatment for aortic occlusions.
• Development and application of a new pathomorphological classification system.
• Description of surgical techniques, including "two-story" reconstructions for extensive lesions.

Main Results:

• 275 reparative operations were performed between 1978 and 1991.
• The proposed classification facilitated tailored surgical interventions.
• "Two-story" reconstructions were recommended for combined femoropopliteal and high aortic occlusions.
• Intraoperative mortality was reported at 1.4%.

Conclusions:

• The authors' classification system aids in selecting appropriate surgical strategies for aortic occlusions.
• "Two-story" reconstructions are effective for complex arterial lesions involving the aorta and femoropopliteal region.
• Surgical treatment of aortic occlusions can be achieved with low intraoperative mortality.
