[Prediction of respiratory complications after radical surgeries for non-small cell carcinoma of the lung].

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.

[Short-term results of radical surgeries for non-small cell cancer of the lung].

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 <> complications and 74 (21%) patients with <> ones. Complications were seen more often in patients over 60 years and occurred less frequently after segmentectomy (7 patients). Lethality was 5.0% (18 patients). Respiratory complications (7 cases) and pulmonary embolism (5 patients) were the main causes of lethal outcome.

[Results of surgical treatment of lung cancer in patients over 70 years old]. / Rezul'taty khirurgicheskogo lecheniia raka legkogo u bol'nykh v vozraste starshe 70 let.

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%.

[Predicting the duration of functioning of iliac artery prostheses]. / Prognozirovanie dlitel'nosti funktsionirovaniia sosudistykh protezov pri protezirovanii podvzdoshnykh arterii.

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.
