Axillary Artery to Contralateral Axillary Vein Graft Fistula in Chronic Hemodialysis Patients

Background.?Vascular access failure is a severe and common complication for hemodialysis patients. The possible vascular access sites are limited in dialysis patients. Axillary artery to contralateral axillary vein arteriovenous fistula (AVF) is one of the possibilities. However, the clinical outcome of this procedure is still un-defined. Object.?The purpose of this study is to review the clinical outcome of axillary artery to contralateral axillary vein AVF as a hemodialysis vascular access. Patients and Methods.?We retrospectively reviewed native or graft arteriovenous fistula records for chronic hemodialysis patients at Chang Gung Memorial Hospital in Kaohsiung, Taiwan, from 01 1986 to 03 2001. Records were reviewed for all chronic hemodialysis patients, with more than 2000 individuals receiving more than 10,000 fistulas. Eight patients received axillary artery to contralateral axillary vein AVF. Results.?The mean age for these patients was 61.7 ± 16.3 year-old at time of surgery. All patients had received multiple native or graft arteriovenous fistula creation. The 2-year and 4-year AVF graft survival is 87.5% and 43.8% respectively. One patients developed brachial plexopathy after operation. Another patient had venous hypertension distal to the AVF site. Both patients were managed conservatively. There is no AVF-related mortality in these patients. Conclusion. We conclude that axillary artery to contralateral axillary vein graft fistula may be a feasible alternative choice for chronic hemodialysis access.     

A Ruptured Pancreaticoduodenal Artery Aneurysm Associated with a Splenic Artery Aneurysm: Report of a Case

True pancreaticoduodenal artery (PDA) aneurysms are extremely rare. We report herein a case of a ruptured PDA aneurysm associated with a nonruptured splenic artery aneurysm which was successfully treated by surgery. A 55-year-old man was admitted to a local hospital complaining of sudden abdominal and back pain, and thereafter he was transferred to our university hospital. Abdominal computed tomography revealed retroperitoneal hematoma and an enhanced round spot suggesting a peripancreatic aneurysm. Emergency angiography showed a 20-mm-sized aneurysm in the inferior PDA and a 10-mm-sized aneurysm in the splenic artery. The patient underwent an emergency laparotomy with a diagnosis of a ruptured PDA aneurysm. After evacuating a large volume clot in the right retroperitoneal space and the peritoneal cavity, we detected an index finger-sized aneurysm with arterial bleeding in the right inferioposterior aspect of the pancreas. Hemostasis was obtained by oversewing the aneurysm and a ligation of the feeding arteries. A prophylactic splenectomy was performed for the nonruptured splenic artery aneurysm. This case indicates that emergency angiography is indispensable for both a definitive diagnosis and adequate surgical treatment of PDA aneurysms.

Anterior Chest Wall Axillary Artery to Contralateral Axillary Vein Graft for Vascular Access in Hemodialysis

Abstract: Patients with end-stage renal failure and peripheral vascular disease pose a difficult management problem in establishing long-term angioaccess for hemodialysis. In 4 patients with access problems, we created axillary artery to contralateral axillary vein Goretex grafts. The grafts were cannulated regularly for periods ranging from 29 to 66 months without difficulty. There was one episode of thrombosis and one of congestive heart failure. The mean venous pressure was 120 mm Hg with a mean arterial flow of 220 ml/min. This type of vascular access can provide adequate blood flow in difficult patients and maintain efficient dialysis. It should be a useful addition to the armamentarium of the vascular surgeon.     

Cerebral Aneurysm Associated with Persistent Primitive Olfactory Artery Aneurysm

Summary Persistent primitive olfactory artery is a rare vascular anomaly but has a clinical importance because of its high association with cerebral aneurysm. We describe a patient with bilateral persistent primitive olfactory arteries associated with an unruptured saccular aneurysm on the left persistent primitive olfactory artery. Seven reported cases with this anomalous artery including ours are reviewed and classified into two variants. This anomalous artery arises from the terminal portion of the internal carotid artery and courses anteromedially along the ipsilateral olfactory tract and makes a hair-pin curve posterior to the olfactory bulb, becoming the distal anterior cerebral artery (variant 1) or the ethmoidal artery (variant 2). Out of 7 reported cases, 4 cases are associated with saccular aneurysms. The aneurysm in variant 1 is located on the hair-pin curve at which an apparent arterial branch is sometimes absent. Two patients suffer from anosmia. Persistent primitive olfactory artery should be kept in mind because of its high association with intracranial saccular aneurysms and unique clinical presentation.     

A Surgical Case of Bronchial Artery Aneurysm Connecting to a Pulmonary Artery and Vein Complicated by Racemose Hemangioma

We report a surgical case of bronchial artery aneurysm (BAA) that directly connected to a pulmonary artery and a pulmonary vein through an abnormal vessel. It was complicated by racemose hemangioma. This is a rare vascular malformation. An 82-year-old female had a large BAA that was found incidentally. First, we consider treating the BAA with embolization by interventional radiology (IVR). However, because of strong meandering of the bronchial artery, we could not advance a microcatheter into the BAA. Therefore, a surgical operation was performed through a standard posterior lateral thoracotomy. The BAA was located between the upper and lower lobes and directly connected to the pulmonary artery. Some bronchial artery branches that provided inflow to the aneurysm were ligated, and the abnormal vessel that connected the BAA to the upper pulmonary vein was ligated easily. A fistula between the BAA and pulmonary artery was sutured by the cardiovascular surgeon using an artificial cardiopulmonary device, with permissive stenosis of A2b (ascending A2).     

合并双髂总动脉瘤的腹主动脉瘤的腔内治疗

目的总结腹主动脉瘤合并双髂总动脉瘤的腔内治疗经验。方法2009年1月～2012年3月,126例腹主动脉瘤接受腔内修复术（endovascularaneurysmrepair,EVAR）,其中33例合并双髂总动脉瘤（直径〉18mm）。27例双侧髂总动脉直径〉18-〈25mm,选择合适口径的髂腿移植物完成传统EVAR;6例因-侧髂总动脉直径≥25mm,选择该侧髂外动脉作为锚定区完成EVAR,并行髂内动脉栓塞术。结果所有腔内技术均获得成功,手术时间（115±36）min,出血量（173±65）m1。术中发现即刻内漏7例（21．2％）：I型内漏3例（近端1例,远端2例,均经球囊扩张后内漏消失）;11I型内漏1例,经扩张后内漏消失;II型内漏2例,Ⅳ型内漏1例,经随访瘤体直径未增大,未予处理。33例术后随访6～39个月,平均15．3月,无动脉瘤破裂,无远端迟发型I型内漏发生,髂动脉直径无明显扩张。结论对于部分合并双髂动脉瘤的腹主动脉瘤患者,根据髂总动脉直径选择合适的腔内治疗方法可以达到理想的治疗效果,近期效果满意。     

A Surgical Case of Bronchial Artery Aneurysm Directory Connecting with Pulmonary Artery

We present a surgical case of bronchial artery aneurysm (BAA) connecting pulmonary artery accompanied with racemose hemangioma. This is a third surgical case report of BAA directly connecting pulmonary artery in the English literature. A 63-year-old female was found a BAA, 2 cm in diameter, connecting right A4 pulmonary artery. The patient underwent two attempts for embolization. However, due to extensive collaterals, there was persistent flow in the aneurysm. Standard lateral thoracotomy was performed. A BAA was located between A4 and A5 PA. A small branch of A4 PA was separated, and the small vessel connecting to the BAA could be ligated. A5 PA was separated similarly, however BAA was ruptured not to identify the other small vessel connecting to the BAA. After a clamp of the BAA, middle lobe lobectomy was performed. We removed the aneurysm with dilated bronchial artery connecting to the aneurysm. The postoperative course was uneventful.
