A patient in whom perforation of a percutaneously inserted intraaortic balloon resulted in a clot formation inside the balloon is described. The balloon could not be withdrawn percutaneously and was lodged in the femoral artery. It was removed surgically, and the artery was repaired.
Transluminal dilatation of seven left subclavian arteries and one right subclavian artery was attempted in seven patients. Dilatation was successful in four left subclavian arteries and the single right subclavian artery treated. Five of the patients suffered from cerebral symptoms as well as ischemia of the upper limb, one had only cerebral symptoms and another had only arm claudication. All patients also had significantly reduced systolic blood pressures in the brachial artery. Standard techniques for percutaneous transluminal angioplasty (PTA) were employed, using the femoral route six times and the axillary route four times. No complications occurred. All patients were permanently given a maintenance dose of antiplatelet treatment with dipyridamole 75 mg tds after PTA. Follow-up of up to 36 months, indicates that angioplasty can be accomplished in the stenosed subclavian artery with relatively little hazard. Patients with hemodynamically significant stenoses should be considered for PTA if their symptoms and signs warrant such therapy.

A peripheral pulmonary artery aneurysm appeared as a solitary, smooth and discrete coin lesion in the lung. The aneurysm was surgically resected. Various etiologies possibly responsible for this entity are discussed. The complications of transthoracic needle aspiration biopsy are reviewed, with emphasis on the hazards of puncturing a vascular lesion, as well as suggested steps to avoid this complication.

In an earlier paper we have shown that manual lymph drainage massage of edematous limbs can result in the excretion of up to 1 liter urine derived from reabsorption and transport from the interstitial fluid, simultaneously with significant changes in the excretion of urinary neurohormones. These findings indicated that histamine and serotonin were released from the edematous tissue and that circulation improved through increased output of adrenaline and noradrenaline. The results achieved led us to assume that similar changes may have occurred in the blood during treatment, and induced us to study the effect of manual lymphdrainage on various blood constituents and urinary neurohormones.
A significant difference in bilateral systolic brachial artery pressures and the presence of systolic bruit over a subclavian artery suggests occlusive disease in the innominate or subclavian arteries. Two thousand patients with these signs underwent ultrasonography of the carotid, subclavian, and brachial arteries in our laboratory. Doppler recordings of a vertebral artery, with hyperemia testing of the ipsilateral arm, identified those with a subclavian steal syndrome. In each case, angiography confirmed the laboratory diagnosis. The effectiveness of corrective surgery was evaluated noninvasively. Illustrative cases are presented and discussed.

After surgery of the aorta and iliac arteries, perioperative information concerning the circulatory status of the legs is vital. In a consecutive series of 71 patients, segmental air plethysmography was used to monitor simultaneously pulse volumes in both legs. Accidental ischemia was detected in four patients, and immediate corrective measures were undertaken. Compared with other methods, plethysmography proved reliable and easy to use.
The results of treatment of 101 combat injuries of the upper extremities are reported. There were 84 acute injuries and 17 late complications. There was a high incidence of associated fractures (35%) and nerve lesions (51%). Over half the injuries were repaired by saphenous vein graft replacement. There were seven early amputations related to a long delay before treatment, extensive tissue damage, and sepsis with delayed hemorrhage. There were no late amputations, but residual neurologic damage gave a less than perfect result in 32 extremities. Two injuries resulted in Volkmann's contracture. Fracture specific to the management of upper-extremity arterial injuries are outlined.
