Penetrating missile embolisation.

The present case report is that of a 13-year-old boy, who was admitted to the Emergency Unit at the American University of Beirut Medical Center (AUBMC), with a bullet injury to the right upper quadrant with no exist. Chest X-ray and KUB failed to reveal the bullet and there was no evidence of haemo- or pneumothorax. X-ray of both thighs showed the bullet at the level of the right groin. The bullet penetrated the liver, diaphragm and pericardium. It entered through the left ventricle and embolised through the arterial circulation to the right superficial femoral artery. Included in this report is a review and analysis of patients with missile embolisation, who were treated at the AUBMC over the last 10 years.

Popliteal vascular injuries and war: are Beirut and New Orleans similar?

Trauma to the lower extremity associated with fracture and vascular injury has a high reported incidence of limb loss. This study reviews and contrasts the experience at Tulane University affiliated hospitals (TU) and the American University of Beirut (AUB) (1980 to 1984), both of which are surrounded by hostile action. Seventy-six male patients (28--AUB, 48--TU) with an average age of 21.2 (TU) and 24.4 (AUB) years (range, 17 to 42) presented with popliteal artery injuries with (34 [14--AUB; 20--TU] ) and without (42 [14--AUB; 28--TU]) associated fractures. All patients were clinically evaluated, angiogrammed, begun on cephalosporin antibiotics, and operated upon. Fractures were treated with extraskeletal fixation or splinting. Time of initiation of operative therapy varied from less than one to greater than 12 hours. When necessary, contralateral limb reversed saphenous vein was used as an interposition graft. Fasciotomies were done for popliteal artery injuries with greater than 6 hours' ischemic time, and combined popliteal artery and popliteal vein injuries. Nine limbs of 76 at risk were amputated: 5/34 (2/14--AUB; 3/20--TU) with popliteal injuries and fractures, and 4/42 (1/14--AUB; 3/28--TU) with popliteal injuries and without fractures. Five of the amputated limbs had initiation of therapy at greater than 12 hours; three had initiation of therapy at greater than 8 hours. Good communication between surgeons, prompt fracture reduction, antibiotics, angiography, and total repair of the vascular injury resulted in limb salvage in 30/40 patients with popliteal artery injury and fracture, and in 39/42 patients with popliteal artery injury without fracture.(ABSTRACT TRUNCATED AT 250 WORDS)

Unusual variation of the arterial pattern of the human upper limb.

The anomalous brachial artery, after giving off a profunda brachii artery with no collaterals, divides in its upper one-third into two equal-sized arteries, brachial arteries #1 and 2. These arteries lie next to each other in the normal path of the brachial artery. Brachial artery #1 is possibly a high-origin and persisting radial artery. It gives no collaterals in the arm. At the cubital fossa, it becomes subcutaneous and divides into two equal-sized radial and ulnar arteries. These arteries run completely superficial to flexor muscles of the forearm and are terminated by branches running above the thenar and hypothenar eminences, respectively. Brachial artery #2 is possibly a high-origin artery of the common interosseous. The course of this artery resembles the course of the brachial axial artery of the embryo. It supplies the anterior compartment of brachial muscles and continues as the common interosseous artery. This common interosseous artery in turn branches into the superior and inferior ulnar collaterals, and the anterior and posterior interossei. It does not regress, but has a major role in forming the deep palmar arterial arch in the hand. The clinical implications of such an anomaly are discussed.
