Acquired coarctation due to calcified thrombus in atherosclerosis of the descending thoracic aorta. Two cases and a review.

An extremely rare manifestation of atherosclerosis is described. Two women, aged 57 and 55, presented with upper extremity hypertension and diminished femoral pulses. Plain radiography and total angiographic visualization of the aorta demonstrated focal highly obstructing intraluminal masses containing heavy flocculent calcification in the upper descending thoracic (case 1) and the thoracoabdominal aorta (case 2) producing a significant pressure gradient. The acquired coarctation due to calcified thrombus was relieved by resection and graft replacement in one and placement of a thoracoabdominal bypass graft in the second patient.

[Isolated fracture of the os trapezium with concomitant dislocation of the carpometacarpal joint of the thumb. A case report].

Fractures of the greater multangular occur mostly combined with additional bone injuries but rarely isolated. This is a report on an isolated fracture of the greater multangular with luxation of the carpometacarpal joint, treated via osteosynthesis. According to most authors and the good result of own case operative treatment is necessary in all dislocated fractures or fractures that cannot be repositioned, to preserve patients from painful arthrosis and reduced function of the thumb.

Intraarticular fractures of the distal humerus. Surgical treatment and results.

In a 12-year period, 104 patients with intraarticular fractures of the distal humerus received surgical treatment. Based on the Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation (AO/ASIF) classification, there were 40 monocondylar fractures, 46 bicondylar fractures, and 18 fractures of the ulnar epicondyle with the fragment dislocated in the elbow joint. In children almost all fixations were done with Kirschner wires. The adult fractures were stabilized according to the recommendations of the AO/ASIF, i.e., monocondylar fractures by screws and/or single-plate fixation and bicondylar fractures by screws and dual-plate fixation, preferably with reconstruction plates. Comminuted fractures required an additional osteotomy of the olecranon. Except for children, the essential feature of postoperative management was early functional treatment by continuous passive motion. Eighty-eight patients (84.6%) were followed with an average follow-up time of 4.4 years. The results were evaluated for range of motion, pain, working capacity, neural and vascular impairment, valgus/varus deformity, and subjective judgment. The long-term outcome of almost 81% good and very good results suggests that operative treatment can be valuable when indications, anatomic surgical reconstruction, and postoperative care are performed correctly.

Unusual cause of recurrent arterial embolism: floating thrombus in the aortic arch surgically removed under hypothermic cardiocirculatory arrest.

A 46-year-old fully active, asymptomatic man suffered two episodes of major peripheral arterial embolism within 2 months. Heart disease was ruled out by appropriate investigations. Further diagnostic evaluation (angiography, CAT scan) revealed the extremely rare finding of a "floating mass" in the transverse aortic arch suspected to be the source of embolization. This mass was successfully removed using the technique of hypothermic cardiocirculatory arrest. The histological diagnosis was an aged intraluminal thrombus and moderate atherosclerosis of the thoracic aorta. For prevention of recurrent arterial embolism in cases without an initially apparent cause and site of origin, a thorough diagnostic, and in a given patient, an aggressive surgical approach for the elimination of the embolic source are advocated.

[The vena cava superior syndrome in sarcoidosis].

We report the first observation of clinical manifestations of vena cava superior syndrome (VCSS) associated with sarcoidosis. Twenty-four years after the first signs of the disease had been noted, mediastinal lymphomas penetrating the wall of the vena cava superior caused complete obstruction. It is most unusual for the vessel wall to be destroyed in this way, which explains why VCSS is often missed in sarcoidosis. The obstructed vessel was resected and successfully replaced by a Gore-Tex prosthesis. The importance of VCSS for the differential diagnosis is pointed out. Two further peculiarities are the simultaneous occurrence of elevated intraocular pressure and VCSS, and the familial incidence.

[The treatment of deep hand infections].

Thirty patients with deep infections of the hand presented between 1982 and 1986 in our Department of Traumatology. Twenty infections were caused by neglected cut- or stab-wounds or animal bite injuries. Mostly Staphylococci or Streptococci were isolated from the wound culture. Only twelve patients could be operated upon ambulatory basis. Postoperative treatment was necessary for more than two months in half of the patients. The patients had a moderate or severe diminution of hand function. All cut- or stab-wounds and human or animal bite injuries of the fingers and hand must be considered as infected wounds. In patients with deep hand infections, surgical debridement and exploration should be performed urgently. Postoperative daily cleaning of the wound, washing out of the infected tendon sheath and passive mobilization of the fingers should be done. The active mobilization starts when infection is regressed and is continued for several weeks. Nevertheless we have to accept a significant loss of hand function in many patients.
