评创伤外科新著《创伤性假性动脉瘤与动静脉瘘》

在创伤外科学中, 血管损伤是一种严重的创伤, 而创伤性假性动脉瘤与动静脉瘘又是血管损伤的严重并发症。以往对其基础研究报道不多, 有关创伤性假性动脉瘤与动静脉瘘的血流动力学、影像学、发病机理等更缺少系统研究,临床救治也只限于直接手术, 还没有规范化治疗方案。因而, 一     

创伤性动脉瘤和动静脉瘘的术式选择

目的探讨复杂的创伤性动脉瘤(TAA)和动静脉瘘(TAVF)的手术方法和疗效。方法对我院1963年6月至2000年12月经手术治疗的TAA和TAVF121例进行回顾性分析。结果TAA71例含91个动脉瘤，TAVF50例含54个动静脉瘘。手术方式包括瘤体切除和端端吻合或血管移植或上下结扎。瘤体上下结扎加血管旁路移植．直接修补或补片。瘘管切除加四头结扎或动静脉移植或动静脉修补。介入栓塞治疗。死亡1例。TAA、TAVF随访率分别为65．7％和60.0％。远期效果好。结论不同部位复杂的TAA和TAVF应根据其不同分型采用不同的手术方式，对选择性病例可考虑做介入治疗。

可脱性微球囊栓塞治疗外伤性颈总动脉假性动脉瘤伴动静脉瘘1例报告

外伤性颈总动脉假性动脉瘤伴动静脉瘘十分罕见。常因病程较长，瘘口周围组织粘连，难以分离解剖两端的动、静脉，手术易出血，使治疗较为棘手。本院1997年应用可脱性微球囊栓塞治疗1例此种病患者，取得良好效果。     

Surgical treatment of post—traumatic pseudoaneurysms and arteriovenous fistulas

Objective:To report the experience in the diagnosis and treatment of post-traumatic pseudoaneurysms and arteriovenous fistulas.Methods:A series of 30 patients(11 women and 19 men) with posttraumatic pseudoaneurysms were reviewed retrospectively.Among them 7 patients (5 women and 2 men) were associated with arteriovenous fistula.Results:The causes included sharp penetration trauma(18 cases),blunt trauma (6 cases) and iatrogenic arterial injury (6 cases).The main clinical manifestations consisted of local pulsatile mass (26 cases),vascular bruits (19 cases),thrill (13 cases),ischemia of distal limb (9 cases),neuropathy (5 cases) and pseudoaneurysm rupture (2 cases).All patients underwent surgery.The operations included:ligation of the vessels (12 cases),surgical resection and primary suture repain of the vascular defect or anastomosis (11 cases),vascular reconstruction with autogenous saphenous vein (3 cases) and synthetic vascular graft (4 cases).Conclusions:Because of the imminent clinical course,early operation is usually indicated.The operative treatment is effective and safe for most of the patients with post-traumatic pseudoaneurysms and arteriovenous fistulas.     

Surgical treatment of complicated traumatic aneurysm and arteriovenous fistula

Objective: To evaluate the surgical methods and the outcome of management for traumatic arterial aneurysm(TAA) and traumatic arteriovenous fistula (TAVF). Methods : A total of 121 patients with TAA or TAVF were treated by surgery. Clinical, operative and postoperative data were collected and analyzed retrospectively. Results : The surgical techniques included aneurysmectomy and arterial end-to-end anastomosis or vascular grafting or artery ligation, aneurysm ligation and bypass, vascular repair, fistula excision and vascular ligation or vascular grafting or repair and so on. One patient died (0.83%). The follow-up rates of TAA and TAVF were 65.7% and 60% respectively. Conclusions: Complicated TAA and TAVF in different sites should be treated with different methods.

Endovascular repair of traumatic arteriovenous fistula between axillary artery and vein

Traumatic arteriovenous fistula between the axillary artery and vein may present a difficult problem in treatment. There are few reports demonstrating the endovascular repair of this challenge. Herein, we present such a case of endovascular repair of traumatic arteriovenous fistula between the axillary artery and vein with false aneurysm formation. The patient was discharged 11 days after successful operation. Oral clopidogrel and aspirin were administerted for 18 months. At one year follow-up, the patient was in good condition and showed no evidence of neurological deficit in the left upper limb.

Successful endovascular treatment for gastroduodenal artery pseudoaneurysm with an arteriovenous fistula after pancreas transplantation

The aim of this study was to demonstrate the usefulness of endovascular treatment for gastroduodenal artery pseudoaneurysm with an arteriovenous fistula after simultaneous pancreas–kidney transplantation. We describe the case of a 38-year-old man who underwent successful simultaneous pancreas–kidney transplantation. An asymptomatic pseudoaneurysm of the donor gastroduodenal artery with an arteriovenous fistula was incidentally diagnosed by routine color flow Doppler ultrasound (CDU) examination and confirmed by 3-D gadolinium-enhanced magnetic resonance angiography (MRA) 15 days after transplantation. Selective arteriography (via the right femoral artery) confirmed an arteriovenous fistula and a pseudoaneurysm of the donor gastroduodenal artery. The patient underwent successful endovascular embolization. At 11 months of follow-up, normal pancreatic function was reported. Endovascular treatment for gastroduodenal artery pseudoaneurysm with an arteriovenous fistula after pancreas transplantation obviates the need for surgical intervention.     

Popliteal pseudoaneurysm and arteriovenous fistula after arthroscopic anterior and posterior cruciate ligament reconstruction: A case report

IntroductionVascular injuries are a well recognised but very rare complication of surgery or trauma around the knee, especially associated with arthroscopic anterior and posterior cruciate ligament reconstruction.Presentation of caseThis report describes a case of a Popliteal pseudoaneurysm and arteriovenous fistula after Arthroscopic anterior and Posterior Cruciate Ligament Reconstruction. An 57-year-old male who complained of pain and swelling around the left lower extremity after the ACL and PCL reconstruction using a semitendinosus graft from the two limbs caused by bicycle accident. He was diagnosed with the popliteal pseudoaneurysm and arteriovenous fistula by the Doppler ultrasonographic examination and CTA, and transferred to the interventional radiology suite where a successful vascular stent implantation was made. There was no postoperative complication.DiscussionThe most important finding of the present case were a popliteal pseudoaneurysm and arteriovenous fistula after the ACL and PCL reconstruction. To our knowledge, very few cases reporting an arteriovenous fistula with popliteal pseudoaneurysm following arthroscopy have been described. Vascular injury is a very rare complication of knee surgery, but surgeons should always consider this possibility in patients who have undergone knee arthroscopy. If the patient has symptoms of pain in the popliteal area and unexplainable swelling following arthroscopic ACL and PCL reconstruction, a popliteal vascular injury should be suspected.ConclusionsIn order to minimize the risk of vascular complications in ACL and PCL reconstructive surgery, we advise to look for less traumatizing instruments and to limit the amount of riskful actions, precise attention should be paid in the establishment of the tibial tunnels.

Surgical management of aneurismal dilation of vein and pseudoaneurysm complicating hemodialysis arteriovenuos fistula

Background  

Pseudoaneurysm (PS) and aneurismal dilation of vein (ADV) are recognized complications of arteriovenous fistulas (AVF) in patients on hemodialysis. We present our experience about surgical management of these complications, which resulted in AVF preservation for continuing hemodialysis.
