[Evaluation of the results of reconstructive operations in patients with occlusive diseases of the abdominal aorta and its branches].

The article deals with the results of studying regional microcirculation in 550 patients with chronic arterial insufficiency. Radioisotope study of blood flow in the muscles with isotopes 131I or 133Xe before and after muscular exertion, morpho-histological++ study of biopsies from a skeletal muscle, histochemical and ultrastructural study of the microcirculatory channel were carried out. Analysis of the findings made it possible to distinguish, according to the changes in circulation in the tissues, three clinical groups of patients (compensated, subcompensated, and decompensated), to determine the indications and contraindications for various types of reconstructive operations, and to prognosticate with high authenticity the outcome of the disease.

[Mechanical obstruction of the duodenum after surgery of the abdominal aorta].

The authors report two cases of duodenal obstruction occurring after insertion of an aorto-iliac prosthesis. This form of mechanical obstruction is much rare than the other forms of post-operative mechanical intestinal obstruction. While the need for surgery is often evident, precise diagnosis before the procedure is seldom obtained. CT scan appears to be the investigation of choice. This complication could be prevented by an epiploplasty covering the graft implant region.

Mycotic aneurysms of the suprarenal abdominal aorta: prolonged survival after in situ aortic and visceral reconstruction.

Necrotizing infection of the arterial wall causes rupture and false ("mycotic") aneurysm formation, with a very poor prognosis if untreated. Cure can be achieved by surgical drainage and debridement, with restoration of arterial continuity through uncontaminated tissues. The dilemma of applying these principles to the treatment of mycotic aneurysms of the suprarenal aorta is that no remote or extraanatomic routes are available to maintain perfusion to the viscera. We report the first case of Klebsiella suprarenal mycotic aortic aneurysm successfully treated with in situ prosthetic reconstruction of the aorta and visceral arteries, and we have reviewed the 21 other suprarenal mycotic aortic aneurysms reported in the English-language literature. Repair was performed in 20 of the 22 cases, with in situ prosthetic reconstruction performed in 18. Prolonged survival has been achieved in 16 patients after in situ repair. No long-term survival has been reported after extraanatomic reconstruction of the aorta and visceral arteries in patients with such aneurysms. We conclude that in situ prosthetic reconstruction, accompanied by thorough drainage and debridement, prolonged parenteral antibiotic therapy, and permanent suppressive oral antibiotics, offers the best chance for survival in these patients.

[The indication for lymph node dissection around abdominal aorta in gastric cancer].

In 77 cases with gastric cancer, for which lymph node dissection around the left renal vein was performed in the past 5 years, the sites and routes of metastasis were investigated to determine the indication for dissection around the left renal vein. The rate of metastasis to the lymph nodes around the left renal vein was 23.4%. The typical routes of metastasis were 1) the left lower phrenic route, 2) via the splenic artery, 3) via the celiac artery, 4) via the superior mesenteric artery and 5) the postpancreatic route. Dissection was considered to be indicated for the patient with N2 or more distant lymph node involvement and for cases with carcinoma of the upper part of the stomach or whole stomach with N2 positive lymph node. It was also indicated for N3(+) cases or No. 9(+) cases of carcinoma of the middle and lower parts of the stomach. Needless to say the absence of other non curative factors is required.

[Value of nuclear magnetic resonance in the detection of false aneurysm of the abdominal aorta].

Among the long-term complications that jeopardize bilateral aorto-femoral prostheses, the development of a false aneurysm on the aortic suture line, is indeed one of the most severe. Its frequency, approximately 1 p. cent of cases, is probably underestimated, since its diagnosis, with usual exploration methods, is difficult. The nuclear magnetic resonance (NMR) examination is here particularly indicated and, when in doubt, must be systematically requested, especially in the presence of a false aneurysm of the femoral suture line.
