Computed tomography and ultrasonography of the hemophilic pseudotumor and their use in surgical planning.

Twenty-one hemophilic pseudotumors in 17 patients were evaluated radiologically to facilitate surgical planning. Plain radiography, angiography, intravenous urography, computerized tomography (CT), and ultrasonography (U/S) were the modalities used. CT proved to be the most efficient method in the detection of bone destruction and soft tissue lesions including additional daughter cysts. The combination of CT, intravenous urography, and angiography were used in pelvic pseudotumors, and that of CT and angiography for extremity pseudotumors, to determine the proper surgical approaches to the lesions. As a non-ionizing technique, U/S was usually preferable in visualizing soft tissue masses and, in sequential studies, to evaluate progress or recurrence of the lesion.

Acquired arteriovenous fistulas of the scalp in hemophiliacs.

The development of arteriovenous fistulas following multiple intravenous infusions in hemophiliacs has been previously reported. In this report, we discuss two patients in whom arteriovenous fistulas developed following the use of scalp veins as sites of infusion. Because of the rich vascularity of this area and the proximity of the arterial and venous systems we recommend that this site not be used for factor infusion.

Prinzmetal's variant angina during extradural anaesthesia.

A 55-yr-old male undergoing varicose vein surgery with an extradural block complained of chest pain. E.c.g. changes and subsequent examination of the heart including coronary angiography suggested the diagnosis of Prinzmetal's variant angina. The therapeutic implications of this condition in patients undergoing anaesthesia and surgery are discussed.

Acromioclavicular dislocations: treatment by transfer of the conjoined tendon and distal end of the coracoid process to the clavicle.

A retrospective study of 23 acute and 6 chronic acromioclavicular dislocations treated by surgical transfer of the distal 1/2 inch of the coracoid process with the attached conjoined tendon of the coracobrachialis and short head of the biceps to the clavicle revealed 14 excellent, 14 good and one fair result. Results were determined according to symptoms, range of motion at the shoulder and elbow, strength, anatomic reduction, and return to previous activities. Although most patients with this injury are treated conservatively, this procedure is reserved for the athlete or manual laborer below age 45 years, especially with involvement of the dominant-extremity. The 29 cases were evaluated 20--108 months following surgery. Thirteen additional cases with less than 18 month follow-up have also been good or excellent. Weakness and pain have not been as pronounced following this procedure in vigorous individuals as have been noted after conservative treatment. Few postoperative complications developed, and early return to competitive athletics was possible.

Management of bleeding and associated complications of hemophilia in the hand and forearm.

Hemorrhage into the hand and forearm in hemophiliacs can be devastating if not treated early and properly. Of 200 hemophiliacs followed from 1969 to 1976, thirty-four had lesions of the hand and forearm. Hemarthrosis, the most common musculo-skeletal manifestation of hemophilia, occurred in the wrist and hand on only ten occasions. Superficial hemorrhage in the seven cases seen was not followed by significant sequelae. Bleeding into the anterior muscles and into the volar aspect of the wrist, on the other hand, was complicated by contracture, neuropathy, or both in six cases. Early diagnosis, replacement of the missing clotting factor, and immobilization are essential. Fasciotomy should also be considered, though it was not done in this series. Once a Volkmann's contracture is established, surgical reconstruction is required. The fractures in the hemophiliacs in this series, as in others, healed with normal periosteal callus formation and at a normal rate. Pseudotumors of the small bones of the hand have been described but were not seen in this series. Conservative therapy is suggested. After appropriate hematological evaluation to identify the missing factor and to exclude the presence of antibodies, it is now possible to control bleeding while proceeding with the necessary treatment to restore function and prevent deformity.

Intramuscular butorphanol and meperidine in postoperative pain.

Butorphanol, 1, 2, and 4 mg/70 kg, and meperidine, 40 and 80 mg/70 kg, were compared for analgesic activity and side effects in 104 hospitalized postoperative patients. Butorphanol proved to be 30 to 40 times as potent as meperidine on a weight basis. Both medications provided maximum pain relief approximately 1 hr after administration. The most common side effect in all groups was drowsiness.

Butorphanol: a double-blind comparison with pentazocine in post-operative patients with moderate to severe pain.

A double-blind, randomized trial was conducted with 124 post-operative patients to compare the analgesic activity and possible side-effects of a new synthetic analgesic--butorphanol tartrate (1, 2, and 4 mg)--and pentazocine lactate (30 and 60 mg), adminstered intramuscularly. Butorphanol was determined to be 16 times more potent than pentazocine, on a weight basis. Both medications provided maximum pain relief within one hour after administration, and had comparable durations of action. Drowsiness was the most common side-effect, and it appeared to be dose related in all test groups.
