[Differential diagnosis of tumors of the gastrointestinal tract and retroperitoneal space from abdominal aortic aneurysms]. / Differentsial'naia diagnostika opukholei zheludochno-kishechnogo trakta i zabriushinnogo prostranstva ot anevrizmy briushnoi aorty.

Aneurysm of the abdominal aorta is often erroneously identified as a gastrointestinal or retroperitoneal tumor of cyst. Out of 54 cases of this disease, 22 patients had undergone long-term examinations at various hospitals, oncological establishments included, while exploratory laparatomy had been carried out in 9 patients. The symptoms of aneurysm are described and compared with those of said tumors. Diagnostic procedures for identification of aneurysm and differentiation from gastrointestinal and retroperitoneal tumors and cysts are discussed.

[Multiple renal arteries and their importance in surgery of aneurysm of the abdominal aorta]. / Mnozhestvennye pochechnye arterii i ikh znachenie v khirurgii anevrizmy briushnoi aorty

Studies of 40 patients with aneurysms of the abdominal aorta, treated surgically, and 152 cadavers of adult persons enabled to state that atherosclerotic aneurysm of the abdominal aorta in vast majority of patients (in 38 of 40) affects its lower portion and is located at the level of the IIId -- Vth lumbar vertebrae. Also, there were found different variants of the anatomical structure of renal arteries and their relationship with the abdominal aorta aneurysms. It is the authors' opinion that a surgeon should be aware of this fact, while acoomplishing surgical procedures, and carefully estimate the value of an accessory vessel in the kidney blood supply, and also reimplant it in the allograft, if possible. It is believed, that if preservation of the mentioned arteries proved to be unfeasible, then either radical operation should be cancelled or the problem should be solved as to the need or rationality of radical operation simultaneously with nephrectomy in unilateral multitude of renal arteries.
