ABSTRACT
A predictive role of volume-velocity (VV) indices of ventilation in prognosis of respiratory complications after radical surgeries for non-small cell carcinoma of the lung was evaluated. It is demonstrated that decreased VV indices of ventilation before surgery directly correlate with a respiratory complication rate after surgery. New methods of diagnosis of ventilation disorders and of monitoring are regarded as promising.

The results of radical surgical treatment of 358 patients with NSCCL were analyzed. Majority of patients were men (84.6%) and persons older 60 years -- 239 (66.8%) patients. Central cancer was diagnosed in 164 (45,8%) patients, peripheral -- in 194 (54.2%). There were 137 (38.3%) pneumonectomies, 184 (51.4%) lobectomies; 149 (41.6%) surgeries were combined. Complications after radical surgeries were seen in 92 (25.7%) of 358 patients, including 18 (5.0%) patients with <

Results of surgical treatment of 345 patients (210 men--61%; 135 women--39%) over 70 years with non-small-cell lung cancer were analyzed. Central lung cancer was diagnosed in 141 (40.9%), peripheral--in 204 (59.1%) patients. Squamous cell cancer was seen in 233 (67.3%), glandular--in 67 (19.4%), dimorphic--in 22 (6.5%), large-cell--in 23 (6.8%) patients. Stage I of the disease was diagnosed in 121 (35.1%); stage II--in 49 (14.1%); stage III--in 175 (50.8%) patients. Rate of postoperative complications in the study group was 27.8%, lethality--6.4%. The highest lethality was after combined pneumonectomy. The most frequent postoperative complications were pneumonia (7.5%), arrhythmia (10.1%), pulmonary-heart insufficiency (4.9%). Five-year survival after radical surgery in patients over 70 years with lung cancer was 49%, in patients with stage I of the disease this parameter was the highest--71.4%.

A formula has been computer-derived to predict the duration of the operation of lavsan vascular prostheses, implanted in the iliac artery. The relative mean-square prognostic error is 2.8%. The formula outlines more specific indications for the implantation of iliac arterial prostheses.
