Conduction anesthesia in orthopedic operations in injuries of the extremities

An analysis of results of using conduction anesthesia for various operations on extremities of 274 patients of different age groups has been made. Complete effects were achieved in 91% of the patients, 5% of the patients were potentiated with neuroleptanalgesia drugs because of insufficient anesthesia, in 2% of the patients general anesthesia was used. The method of conduction anesthesia makes it possible to use a conveyer method of bringing patients to the operating room. It is more economical as compared with narcosis, easy in use. It may be recommended for wider use.     

Status of the coronary bed in post-infarction stenocardia

Selective coronary angiography was performed in 80 patients with early postinfarction angina. All patients showed stenoses in at least one artery. Two vessels were affected in 37.5%, three vessels, in 51.3%, one vessel, in 11.3%. In 8.8% of cases, left coronary-arterial trunk was affected in addition to other arteries. Complete occlusion of one or several arteries was noted in 62.5%. There were marked collaterals in 20% of patients. The only difference between patients who showed relative resistance to medication and those whose condition could be stabilized was in the number of occluded vessels (69.2 and 35.1%, respectively). Coronary arterial lesions were operable in 68% of cases.     

Temporomandibular joint: morphology and signal intensity characteristics of the disk at MR imaging

Magnetic resonance (MR) imaging has been used in the temporomandibular joint (TMJ) primarily to define the disk position. This report examines altered morphology and signal intensity characteristics of the TMJ disk as they relate to the severity of internal derangement. Two hundred sixteen joints in 133 patients with a history of such derangement. were imaged with MR. Disk position, signal intensity, morphology, and the presence of osteoarthritis were determined for each joint. The normal disk was not anteriorly displaced and had a normal "bow-tie" shape. A grade 1 disk was anteriorly displaced and had a normal shape; a grade 2 disk was anteriorly displaced and had an abnormal shape. Forty (19%) joints were considered normal; none of these exhibited osteoarthritis. One hundred thirty-nine (64%) joints were grade 1; osteoarthritis was found in 17%. Thirty-seven (17%) were grade 2; osteoarthritis was found in 95%. All forty normal joints had high or intermediate signal intensity in the disk. Osteoarthritic joints had a higher percentage of disks with diminished intensity (P less than .0001). Severe or untreated osteoarthritis is known to be a complication of TMJ internal derangements; hence this grading system seems to correlate with the severity of internal derangement.

2 cases of deep arteriovenous malformations combined with aneurysms of the anterior ciliary artery

The paper presents two cases of high-surgical-risk deep arteriovenous malformations (AVM) concurrent with aneurysms of the middle portion of the anterior ciliary artery (a male aged 35 years and a female aged 24 years). In the former case, aneurysm and large AVM in the left visual tuber were causes of 4 hemorrhages. In the latter, AVM of subcortical nodes and internal capsule were responsible for single hemorrhage. The patients underwent intraoperative embolization of the anterior ciliary artery followed by its clipping. This allowed the authors to exclude aneurysm and to achieve obliteration of the bulk of AVM. Operation were performed under intraoperative guidance of motor and speech functions. Residual AVM were exposed to proton beam radiation. The outcomes of treatment were good. After 4 months of surgery, the male had no neurological disorders; in the female motor and speech disorders were associated with prior hemorrhage.     

Substitution of an extensive defect of tissues after resection of the sternum in tumors

An original method of substitution of great defect of the soft tissues and osteochondral part of the chest wall after resection of the sternum for a malignant tumor is described. Operations were made on 4 patients. Favorable results were noted in all the patients. The terms of follow-up were from 6 to 25 months.
