摘要:

AbstractNumerous agents have been administered in an attempt to achieve specific biochemical antiplatelet activity. A model of microsurgical trauma was utilized to create a nonocclusive thrombus, similar to what occurs in the postoperative period. Prostacyclin (PGI2) was given in a high intravenous dose which caused in vitro inhibition of platelet aggregation in rats and rabbits. Although hematological and cardiovascular side effects of PGI2were tolerated, in vivo platelet thrombus formation persisted and constituted 25–75% of the postoperative thrombus. Even though platelets were inhibited by PGI2, other significant stimuli remained at the site of injury for activation and participation of platelets in the formation of a thrombu

摘要:

AbstractThis experiment evaluated the influence of blood on the weld strength of laser‐assisted microvascular anastomoses (LAMA). Rat femoral arteries were anastomosed end‐to‐end by either direct laser welding (group I) or by a bloodbonded technique (group II) whereby fresh blood was applied to the vessel edges before laser exposure. Bursting strength was measured at 0, 1, and 24 hours and at 3 and 7 days by infusing methylene blue into the vessel while pressure was monitored. The results showed significantly increased bursting strength in group II compared with group I at 0 hour and 7 days (P<0.05). There was a significant increase in bursting strength in group I from 0 hour to 1 hour (P<0.05). It is concluded that blood‐bonding enhances the early bursting strength of LAMAs and may facilitate arterial wall

摘要:

AbstractA new microsurgical revascularization technique for anterior cerebral artery ischemia is reported. An arterial graft bypass interposed between the superficial temporal artery and the distal anterior cerebral artery was successfully completed in a 43‐year‐old male with transient ischemic attacks in the anterior cerebral artery territory. The contralateral superficial temporal artery was harvested and used as an arterial graft. Both procedures were carried out with one single transcoronal scalp incision. The patient's postoperative cerebral angiogram revealed good filling of the area distal to the stenotic lesion of the anterior cerebral artery through the bypass graft. The patient was discharged with no neurological deficit and has been free of ischemic events for more than 2 years since the surgery. If the bilateral superficial temporal arteries are fairly well developed, the ipsilateral superficial temporal artery can be used as an arterial graft for revascularization of the anterior cerebral artery territ

摘要:

AbstractThe thoracodorsal artery supplies the latissimus dorsi and serratus anterior in the rat in the same fashion as in the human. In the rat, the thoracodorsal artery and vein average 0.57 mm and 0.71 mm in diameter, respectively, at their origins and can be used as pedicles averaging 19 mm in length to the latissimus dorsi muscle and 27 mm to the serratus anterior muscle. We successfully transferred both of these muscles to groin vessels by means of end‐to‐end or end‐to‐side anastomoses. The serratus anterior muscle was technically easier to transfer because its pedicle was longer. We conclude that the serratus anterior transfer in the rat is a feasible animal model for microvascular muscle transfer and may be a useful standard model for pharmacological and biochemical studies in transplanted

摘要:

AbstractRecently sodium fluorescein has been used to determine viability of tissue and assess blood flow. No study, however, has documented the correlation of surface fluorescence as measured by the dermatofluorometer with the actual distribution of fluorescein in tissue. Abdominal skin flaps were raised on Sprague‐Dawley rats. Following intravenous injection of sodium fluorescein, skin surface fluorescence was measured and compared with tissue fluorescein concentration. This study confirms that skin surface fluorescence correlates well with actual fluorescein distribution in tissue. Furthermore, the study clearly illustrates the statistically significant variation of surface fluorescence as a function of distance from the vascular pedicl
