Axilloaxillary bypass: is it worthwhile?

To evaluate the efficacy and long-term patency results of axilloaxillary bypass, a review of 32 patients with follow-up extending to 11 years was done. Twenty-two bypasses were performed for vertebrobasilar symptoms or subclavian steal and 10 for upper extremity claudication and/or ischemia. The mean age of the operative group was 66 years, 94% of patients had more than one atherosclerotic risk factor (hypertension, diabetes, coronary artery disease, smoking), and 75% had undergone a previous arterial reconstruction operation. There were no operative deaths, and the only postoperative complication was a sterile seroma which responded to aspiration. At late follow-up extending to 11 years, three grafts had thrombosed while another became infected and had to be removed; no limb loss resulted from these graft failures and the actual late patency rate was 87%. Carotid-subclavian bypass, intrathoracic bypasses, and endarterectomy at the site of occlusion have all been suggested for the treatment of symptomatic proximal subclavian artery disease. With axilloaxillary bypass, however, the hazards associated with carotid artery manipulation, operation on the notoriously treacherous subclavian artery, and the morbidity related to thoracotomy in this older, high-risk patient population can be avoided. The axilloaxillary bypass is safe and simple, and the excellent long-term patency rates make it the procedure of choice for symptomatic subclavian artery disease.     

Transthoracic aorto-axillary extra-anatomical bypass for difficult subclavian artery revascularization: a multicenter patency study

In situ revascularization of the subclavian artery can be challenging in the context of emergency situations, a large aortic aneurysm with a posteriorly displaced left subclavian artery, a complex redo procedure or in the presence of an aberrant subclavian artery. A transthoracic aorto-axillary extra-anatomical bypass is a low risk alternative to in situ revascularization or carotid to subclavian bypass. We herein describe the surgical steps during a single-stage surgery complex aortic arch surgery. We report a 95.3% graft patency for 77 consecutive transthoracic aorto-axillary extra-anatomical bypass performed to 66 patients at the mean follow-up of 2.9 ± 2.4 years. We encountered 3 early (before 180 days postop) graft failures and no late graft failure. Graft failure had no clinical significance.

Surgical bypass for subclavian vein occlusion in hemodialysis patients

BACKGROUND: The majority of patients with end-stage renal disease are dependent on hemodialysis. Significant stenosis or occlusion of the subclavian vein is known to occur in 20% to 50% of patients who have had central venous catheters inserted into the subclavian vein or the internal jugular vein. Surgical bypass of the obstructed venous segment proximal to a functioning dialysis access site is an established treatment to relieve symptoms and salvage the functional dialysis access. STUDY DESIGN: A retrospective review of all subclavian venous bypass procedures performed at St Louis University Hospital from May 1987 to May 2000 was undertaken. Twelve procedures were performed during this time. The mean age of the patient was 55.5 years (range 17 to 72 years). There were 11 men and 1 woman. Before surgical bypass, all patients underwent bilateral venograms to evaluate their central venous systems. RESULTS: An extraanatomic surgical bypass was performed in all patients. Patients were followed for a mean of 16 months (range 1 to 79 months). At 1 month, 100% of hemodialysis access sites remained functional. At 1 year, 80%; 2 years, 60%; and 3 years, 25% of the salvaged arteriovenous hemodialysis access sites provided for functional dialysis. One patient required thrombectomy of the bypass graft at 14 months. CONCLUSIONS: Surgical bypass of an occluded or stenotic subclavian vein segment is successful in providing both symptomatic relief and salvage of a functioning dialysis access in the hemodialysis patient population. Study of the central venous system is essential in selecting an appropriate bypass procedure in individual patients.     

Axillo-axillary bypass with polytetrafluoroethylene graft for coronary subclavian steal syndrome

The purpose of this study is to report the results of axillo-axillary bypass (AAB) for coronary subclavian steal syndrome due to proximal subclavian artery occlusion. From 2003 to 2010, AAB using a polytetrafluoroethylene (PTFE) graft was performed in 11 patients with coronary subclavian steal syndrome. There was no perioperative mortality, stroke or cardiac complications. Over a mean follow-up of 36 months (range: 6-81 months), all bypass grafts have remained patent. No patient developed recurrent symptoms of myocardial ischemia. One patient died from hemorrhagic stroke at 31 months. Our results showed that AAB using a PTFE graft provides an effective and durable treatment option for coronary subclavian steal syndrome when attempted endovascular therapy of the occluded proximal subclavian artery is unsuccessful.     

Indication and results of surgical treatment of intermittent claudication]

In order to clarify the propriety of surgical treatment for intermittent claudication caused by arteriosclerosis obliterans (ASO), indication for vascular reconstruction and efficacy of surgery on patient's quality of life were investigated. Bypass surgery or laser angioplasty (PTLA) was undertaken in 149 of 188 ASO patients. Because of high risk factors (renal failure, ischemic heart disease, cerebro-vascular disturbance or malignant tumor), 39 patients were treated conservatively. Intellectual dysfunction in aged patient was evaluated by Okabe's brief mental scale test. Coronary artery disease was revealed by coronary angiography performed next to routine dipyridamole-loaded ECG in 19 to 78 patients. CABG or PTCA was performed prior to peripheral vascular reconstruction in 3 patients with serious coronary disease. Extra-anatomical bypass or PTLA was indicated mainly in patients with coronary artery disease or intellectual dysfunction. The anatomical bypass and the extra-anatomical bypass were undertaken in 88 and 61 patients respectively. Graft occlusion was observed in 8 cases. Patency rate of the anatomical bypass was 96.6% and that of the extra-anatomical bypass was 91.8%, at 32 months of postoperative mean follow-up period. The operative mortality rate was 2.7%. There was no major amputation due to graft occlusion.     

血管腔内技术与手术治疗锁骨下动脉闭塞症

目的探讨血管腔内技术与手术治疗锁骨下动脉闭塞症的临床效果及合适的治疗程序。方法1997年6月至2004年5月采取血管腔内技术与手术治疗锁骨下动脉闭塞症39例。26例患者采用血管腔内治疗,置入27枚支架,14例经股动脉途径,12例经肱动脉逆行支架置入,其中8例在彩色多普勒超声定位下穿刺肱动脉。13例未能行支架置入,行血管旁路转流术。9例伴有颈动脉或椎动脉严重狭窄者行支架置入。结果39例患者术后患侧与健侧血压差<10mmHg(1mmHg=0.133kPa),患侧/健侧血压指数由术前的平均0.62±0.11提高至0.98±0.04(t=4.738,P<0.01);腔内治疗患者与手术患者平均血管通畅时间分别为(57.6±3.7)和(60.2±7.2)个月。结论血管腔内治疗与手术治疗锁骨下动脉闭塞症疗效相当,由于血管腔内治疗的微创性和安全性,应优先选择血管腔内治疗。     

Surgical treatment of superior vena cava syndrome (SVC)

SVC syndrome is occurred by the occlusion or stenosis of the superior vena cava secondary to malignant mediastinal tumor. Up to this report, surgical intervention has been thought to be difficult. Recently, extent of the tumor has been diagnosed exactly by CT scan, NMR, and angiography. Several cases undergoing complete resection of the tumor with the technique of vascular surgery have been reported. During the past 10 years, we have experienced 21 cases of SVC syndrome. 16 patients had operations and 5 patients had radiation or chemotherapy. The methods of operations were as follows: complete resection of the tumor 1, complete resection of the tumor and reconstruction of SVC 2, subtotal resection of the tumor and reconstruction of SVC 2, bypass of SVC only 5, extra-anatomical bypass 3. PTFE grafts were placed between right subclavian vein and SVC or left subclavian vein and right atrium. Extra-anatomical bypass were placed between jugular vein and femoral vein. PTFE bypass graft provides effective treatment for SVC obstruction with immediate and long term relief of SVC syndrome.     

Subclavian transposition and carotid-subclavian bypass in the treatment of subclavian steal syndrome

The authors operated on 89 patients for subclavian-steal syndrome, between 1975 and 1984. A carotid-subclavian bypass was applied to 53 patients and transposition of the subclavian artery to another 36. All transpositions were open after an average follow-up period of 2.7 years, where an occlusion was recorded after 4.6 years from eight patients (19.5 per cent) to whom a bypass had been applied. Postoperative complications were equal in both groups. A complex of Horner symptoms was recorded from either group. Phrenoparalysis was recorded from six patients with carotid-subclavian bypass and from four patients with subclavian transposition.     

Hybrid management of proximal right subclavian artery aneurysms

Surgical repair of proximal right subclavian artery aneurysms can be difficult. They typically require a combined mediastinal exposure to control the innominate and right common carotid arteries and a supra- or infraclavicular exposure for distal control, with either a segmental resection and bypass or a bifurcated reconstruction. In this report, we present four cases utilizing a single-stage, hybrid technique combining an endovascular stent graft and an extra-anatomical bypass to repair proximal right subclavian artery aneurysms without the need for mediastinal exposure or extensive surgical reconstruction. There were no deaths and two minor neurologic events.
