目的总结心脏大血管穿透伤的临床特点、早期诊断和救治经验，提高抢救成功率。 方法回顾性分析2007年7月至2014年6月我院26例心脏大血管穿透伤患者的临床资料，男23例、女3例，年龄16～71（22.0±8.4）岁。其中刀刺伤25例，钢锥刺伤1例；心脏穿透伤23例，升主动脉刀刺伤2例，主肺动脉刀刺伤1例；心脏压塞型7例，失血休克型8例，心脏压塞+失血休克型2例，亚临床型9例。26例就诊后30 min至3 h急诊在全身麻醉下行开胸手术治疗，侧开胸手术20例，前正中开胸手术6例，其中2例在体外循环下手术。 结果全组死亡2例，均为失血休克型，1例69岁右心室贯通伤和右冠状动脉主干损伤男性患者术中死于低心排血量综合征，1例38岁右心室前壁穿透伤男性患者术后死于纵隔感染导致的多器官功能衰竭，其余患者痊愈出院，救治成功率达92.3%。18例随访1个月至7年，无后遗症发生。 结论迅速明确伤情，及时诊断，急诊开胸探查是提高心脏大血管穿透伤抢救成功率的关键。
Objective To research the mechanisms, diagnosisand repair methodof venous trunk injuries without accompanied arterial injuries in extremities. Methods From January 1993 to June 2002, 12 cases of venous trunks injuries without accompanied arterial injuries in extremities were treated. All the patientswere males, their ages ranged from18 to 35 years. The interval between injury and operation was 30 minutes to 2 hours. The cause of injury was stab wound. Along with the antishock, the injured vessels were mended in 7 cases, end-to-end anastomosis wasperformed in 5 cases, and the operations were given in the patients with red wounds of the skull, chest or abdomen. Results One case died of severe cerebral trauma, the other 11 cases obtained primary healing. Dopplersonograpy showed that the blood vessels were patent. After a follow-up of 1 -5 years(2 years and 4 months on average), 8 cases recoveredthe function and circulation of extremities; and 3 cases accompanied with red injuries of nerves recovered the circulation of extremities, but did not recover the function with sensory disability and dyskinesia. Conclusion Emergent hemostasis, antishock, repair of the injured vessels as soon as possibleand treatment of associated injuries are important measures to save patients’ life in treating venous trunk injuries without accompanied arterial injuries in extremities.
Objective To investigate the results and applicationvalue of crotch-shaped vein grafts in repairing defects of the vessels with a large diameter.Methods From June 1998 to October 2003, 35 cases of vesseldefects with a large diameter were repaired with crotch-shaped vein graft (29 males and 6 females,aged 18 to 45 years with an average of 25.7 years ). The locations of defects were femoral artery in 25 cases, popliteal artery in 2 cases, femoral vein in 7 cases, and subclavian vein in 1 case. The interval between injure and operatioinwas 1-8.5 hours (4.1 hours on average).The blood flows of trouble and healthy vascular were determined with Doppler detector and compared preoperatively andpostoperatively. Results All the anastomotic stomas were patent in 35 cases. Thirty-one cases were followed up 6 weeks to 24 months (9.5 months on average), the patent rate was 100%, no case occurred vasospasm or tromboembolism; 2 cases occurred stomal leak and became hematoma, 3 cases occurred muscular necrosis, and the 5 cases achieved primary healing after secondary operation. The Doppler results showed that there was statistically significant difference in the blood flow betweenpostoperation and preoperation (Plt;0.01), but no statistically significant difference when compared the trouble vascular after operation with healthy vascular (Pgt;0.05). Conclusion The methodof crotch-shaped vein grafts is safe and effective in repairing defects of vessels with a large diameter,which is easy to draw materials and handy to operate. It has a promising value in clinical application.
Objective To repair defects at both ends of theblood vessels with a considerable disparity in the diameter of the both sides or with a large diameter in extremities by phleboplasty of branched and double autogenous veins. Methods Three kinds of phleboplasties——funnel-shaped, raincape-shaped and transposed Y-shaped were designed. Experiments in fresh blood vessels in vitro were completed successfully. These methods were used clinically to repair injured external iliac veins, femoral arteries and veins, and popliteal arteries and veins, to replant severed fingers and to transplant toenail flaps on thumbs by harvesting autogenous great saphenous veins,small saphenous veins and forearm veins in 36 cases, including 35 cases in emergency operation and 1 case in selective operation.The length of grafted blood vessels ranged from 1.0 cm to 15.0 cm. Results The phleboplasties of funnel-shaped could enlarge the diameter by 1.0-1.25 times inanastomotic stomas. The phleboplasty of raincape-shaped could enlarge the diameter large enough to meet the demands for various blood vessels in extremities. The phleboplasty of transposed Y-shaped could provide large vein transplants. In36 grafted veins, 35 were in patency. The blood supply in extremities was normal.ConclusionThe funnel-shaped and raincape-shaped phleboplasties of branched veins can enlarge the anastomotic stomas of grafted veins. The transposed Y-shaped phleboplasty of double femoral veins is an ideal way to repair injured primaryblood vessels with a considerable disparity in the diameter of the both sides or with a large diameter in extremities.
