The current literature suggests that the optimal range of radial artery for maximum performance (maturation and primary patency) of RCAVF is at least 2 mm (level 2, grade a). The cephalic vein diameter of at least 2 mm (non-augmented) can result in best maturation and primary patency outcomes (level 2, grade a) and threshold below 1.5 mm is not advocated (level 2, grade b).

Mid-aortic syndrome (MAS) is an uncommon condition characterized by segmental narrowing of the proximal abdominal aorta and ostial stenosis of its major branches. It is usually diagnosed in young adults, but may present in childhood as a challenging problem. Over the past 20 years 13 patients with MAS have presented to this institution. All had hypertension, four had associated neurofibromatosis, three persistent eosinophilia and three had Williams syndrome. In all cases arteriography showed a smooth segmental narrowing of the abdominal aorta with concomitant stenosis at the origins of the renal arteries. Six children were successfully treated with antihypertensive medication alone. Percutaneous transluminal angioplasty was attempted in two cases with poor result. Surgery was indicated in seven children with refractory hypertension and progressive renal impairment. Techniques used to revascularize the kidneys included thoracoabdominal to infrarenal aortic bypass with renal artery reimplantation, splenorenal bypass, gastroduodenal to renal bypass, aortorenal bypass and autotransplantation.

The CEUS with its dynamic nature and longer scanning window demonstrated to be a highly sensitive modality for endoleak detection in comparison to CTA in delayed endoleaks type II.

The pathogenesis of donor artery aneurysms remains contentious. This review suggests that duplex is the investigative modality of choice and aneurysmectomy with interposition grafting is preferred over bypass.

A preoperative NLR >5 is an independent predictive marker of 30d morbidity in rAAAs. This appears to be in line with earlier literature demonstrating similar outcome in the elective group of abdominal aortic aneurysm.

Of all the variables, cephalic vein and radial artery diameter are independently associated with the primary functional maturation of RCAVFs.

Standard stripping of the GSV and invagination stripping are not associated with major discomfort and problems in the early post-operative period. SFJ ligation and GSV reverse foam sclerotherapy yielded greater patient satisfaction with less post-op bruising and discomfort and reduced analgesic requirements.

The patency rate of femorotibial and peroneal bypass depends on the inflow state, the availability of a venous conduit, the number of calf vessels, the presence of straight flow to the foot and the presence of patent pedal vessels. These factors can help in the selection of patients for femorodistal reconstruction and may explain the wide variation in published results. The low cost of revascularization compared with amputation justifies attempted reconstruction. However, repeated attempts to reconstruct patients with severe distal disease who may benefit more from primary amputation will significantly increase the cost.
