Prolongation of allogeneic heart graft survival in the rat after implantation on portal vein.

In rats, heart allografts with venous drainage via the portal vein were performed and compared with similar grafts draining into the inferior vena cava. A new technique was developed using the complete thoracic descending aorta and ligation of all its branches. The descending thoracic aorta was anastomosed to the recipient's abdominal aorta below the left renal vein. The pulmonary artery was implanted on the portal vein in an end to side fashion. In two rat strain combinations the allograft survival time was significantly prolonged when compared to that of the control grafts with pulmonary-caval anastomosis. The presumed mechanism for this prolonged graft survival might be the sequestration or degradation of transplantation antigens in the liver during their first passage through this organ. In this way only a small amount of antigen reaches the systemic circulation.

[Reimplantation of fingers (author's transl)].

Three fingers have been reimplanted at present, bij means of microsutures of digital arteries and veins. The help of the surgical microscope is essential to this technique. In case of traumatic amputation of many fingers, with a neat minimal section, the chances of success are particularly good with a low risk of infection.

Serratus anterior muscle in composite head and neck flaps.

The serratus muscle (SAM) can be raised as an isolated muscular or osteomuscular flap on its nutrient vessels or in combination with a latissimus dorsi (LD) myocutaneous flap on the thoracodorsal pedicle for various reconstructive purposes. The aim of the present is to report on the results achieved after the use of the SAM alone (n = 7) and in combination with an LD (n = 3) after tumor resection or osteoradionecrosis (ORN) in ten patients with defects of the head and neck. One flap was lost due to venous thrombosis. The donor site morbidity was minimal. Emphasis is given on a new indication, namely ORN of the mandible. Short-term results show that the use of the SAM prevents a pathologic fracture in cases of a class IIIa osteoradionecrotic mandible. More extensive use of the SAM flap is advocated.

Glans ischemia after penis revascularization: therapeutic embolization.

A case of hypervascularization of the penis with glans ischemia after venous leakage procedure followed by revascularization of the penis is reported. The venous bypass between the inferior epigastric artery and the dorsal penile artery was misplaced on the deep dorsal vein leading to venous hypertension of the glans. Transcatheter embolization of the venous bypass cured this complication.

Late results in replanted digits. Is replantation of a single digit worthwhile?

During the period 1980-1989 35 patients with successfully replanted digits could be selected. Only 17 patients with 32 long fingers and 2 thumbs replanted were prepared to cooperate for this retrospective study, looking for the late functional results. Mobility of the replanted digits was measured by the TAM-value. Power was indicated by grip strength and tip pinch. Weber two-point discrimination test and Von Frey test were used to investigate sensibility. Most patients show cold-intolerance. Mobility was worse for the more proximal replantations. Replantations distal to PIP do functionally very well. Therefore single digit amputations should be considered as an indication for replantation, especially amputations distal to the pip. Ring and little finger replantations have a better mobility than index and middle fingers. Mobility in younger patients is also better. Grip strength and tip pinch are respectively 66% and 73% of the normal values. All patients (except 2) could return to their work in a reasonably short time (average 5 months).

Vasoepididymostomy to the head of the epididymis: a comparative study of two microsurgical techniques in the rabbit.

In an experimental animal study, two different microsurgical techniques of vasoepididymostomy to the caput epididymidis are compared: an end-to-side anastomosis with the epididymal tubule and an end-to-end anastomosis with a section of a cluster of the epididymal tubule. The patency rates are respectively 50 per cent and 26.3 per cent, as controlled by deferentography and histology. Examination with scanning electron microscopy, shows that the superiority of the first method is due to the better apposition of both mucosas .

The treatment of flexor tendon lesions of the fingers.

In this study we checked the functional results of flexor tendon sutures in a group of 50 non-selected patients, observed during 4 to 5 years. The functional results of our 84 flexor tendon sutures speak well for primary suturing with favourable wound conditions. This applies to all zones, even to Zone Ii where a primary repair does not exclude the possibility of a successful secondary tendon graft using Hunter's method. In case of a cut of the profundus and superficialis tendons in Zones II and III, the question of whether both tendons or just the profundus should be repaired, will be answered by the levels of the cuts. In Zone II the superficialis tendon is better left untouched, as a resection produces less favourable results owing to the traumatization of the tissues. For the pollicis longus a critical localization of the tendon sheath, distal to the metacarpophalangeal joint, may be an indication for a tendon transfer or transplantation. The minimally traumatizing technique and adequate postoperative rehabilitation and follow-up do explain the good results, even in Zone II where they reached a 66% rate.

[Fingerreplantation results since 1972 (author's transl)].

With the use of microvascular techniques 31 out of 45 fingers were successful replanted since 1972. A primary reconstruction of all structures was performed, without bone shortening. Vein-grafts had to be used extensively. The microvascular and digital nerve repairs were performed with 11/0 nylon. The microvascular anastomosis was performed starting at the posterior wall, and progressively coming to the anterior wall, without rotation of the clamps. The results of near total amputations were always good. In complete guillotine amputations the successrate was 75%. In crush lesions 59% and in avulsions 40% success was obtained. After a period for improvement of our microsurgical techniques the results were 90%, 91% and 40% respectively. The functional rehabilitation of the replanted fingers resulted in a useful hand in crush and avulsion trauma and in a very useful hand in guillotine lesions.
