Vascular surgery, lead by cluster vascular surgeon Dr. Edward Hui, offers investigation and treatment of a wide spectrum of arterial and venous diseases. Our non-invasive vascular laboratory provides comprehensive service in duplex ultrasound diagnosis, preoperative assessment and postoperative surveillance of arterial and complex venous disease. We are one of the vascular centers performing elective and emergency stenting for aortic aneurysms. More challenging aortic anatomy can now be tackled by different adjunct procedure including renal artery stentings (Chimney Techniques), iliac bifurcated device and fenestrated endovascular aortic stenting. We also provide both endovascular and open surgery for carotid artery disease and peripheral vascular disease. Renal access surgery and intervention are also within our scope of service.

Vascular Surgery

Our vascular surgery, in collaboration with Ruttonjee and Tang Shiu Kin Hospitals, is led by our Dr. Edward Hui, who is the head of vascular surgery in the Hong Kong East Cluster. Open surgery was the only treatment option of large, juxtarenal abdominal aortic aneurysm. However, with the development of endovascular aortic stenting (EVAR), and together with adjunct procedures such as fenestrated EVAR, renal artery stentings (Chimney Techniques), iliac bifurcated device, this minimal invasive endovascular treatment option can be extended to more challenging arterial anatomies and benefit more potential patients. Using this complete endovascular approach in patients with suitable anatomy, the 30-day mortality, postoperative pain and hospital stay are reduced.


  

Our center is one of the local institutions in the evaluation and provision of this technique. Fine cut computer images with 3D reconstruction give precise measurements and planning of the procedure. EVAR is also extended to treat symptomatic and even rupture AAA.

The operation is performed in our endo-lap OR equipped with vascular table, angiographic pressure injector, mobile C-arm image intensifier which is capable of real time angiography and video-subtracted angiography. The installation of advanced technology in operating room ensure safe and smooth operation of advanced endovascular procedures in theatre setting.

Our non-invasive vascular laboratory located at the surgical day ward is jointly operated by the Department of Surgery and Department of Radiology. It provides comprehensive service in duplex ultrasound diagnosis, preoperative assessment and postoperative surveillance of arterial and complex venous disease. Patients with peripheral vascular disease often have other co-morbidities and various risk factors of atherosclerosis. Besides medical therapy and risk factors modifications, revascularization provides symptom relief and limb saving for those with lifestyle restricting claudication and those with critical limb ischaemia. Preoperative assessment of CT angiogram with reconstruction allowed preoperative assessment and planning. Angioplasty is performed in endo-lap OR, with feasible of conversion to bypass surgery when required.

Carotid stenosis is a common cause of stroke. Timely performed carotid endarterectomy can significantly reduce subsequent recurrence risk of stroke. We perform this prophylactic surgery on regular basis, the vast majority of which are under regional anesthesia when the patient remains awake during the procedure. This awake test is most sensitive in determining the cerebral function of the patient.

Varicose vein is a common disorder. Our non-invasive vascular laboratory provides duplex imaging for those with complicated venous disorder. Endovenous radiofrequency ablation of the long saphenous vein (LSV) as a minimal invasive approach for patient with LSV reflux can be performed, with the benefit of less wound complication. Also in those patients with incompetent calf perforators and unhealthy skin, endoscopic subfascial perforator ligation allows a minimal invasive tool to control these perforators to reduce wound complications.
