Aims: The incidence of deep vein thrombosis (DVT) following ultrasound-guided foam sclerotherapy (UGFS) varies from 0 to 5.7%. The aim of this study was to assess the incidence of DVT following UGFS in a single vascular centre.

Methods: Consecutive patients undergoing UGFS between December 2005 and September 2011 attended within 2 weeks of treatment for quality control duplex imaging, performed by a senior vascular scientist independent of the operator. DVT when present was labelled as ‘Endovenous Foam Induced Thrombosis’ (EFIT) type 1 when thrombus was lining <25% of the lumen of the deep vein; type 2 when thrombus extension was 25-50%; type 3 when thrombus extension was 50-99% and type 4 when the deep vein was occluded.

Results: A total of 1166 UGFS treatments were performed in 1000 legs (776 patients); following which 17 DVTs were detected (1.5%). No DVTs were detected in legs undergoing multiple treatments. Seven DVTs were EFIT type 1, two were type 2, two were type 3 and five were type 4. One DVT was seen in the gastrocnemius vein alone. Two of 1166 treatments (0.2%) resulted in a symptomatic DVT, both of which were EFIT type 4. On regression analysis, there was an increase in the risk of DVT when =10mls of foam was injected (OR=4.58, 95% CI=1.42-14.8; p=0.01).
 
Conclusions:  The incidence of duplex detected DVT following foam sclerotherapy is low and may be associated with the injection of high foam volumes. However, the rationale for routine post-procedure duplex imaging is debatable, given that clinically significant DVTs are rare.

Aims: Laparoscopic aortic surgery is an alternative or adjunct to open or endovascular repair and may confer certain advantages. Our experience of laparoscopic aortic aneurysm surgery is reported.

Methods: Prospectively collected data was recorded on patients undergoing elective laparoscopic assisted or total laparoscopic aortic surgery from three vascular centres. 

Results: Eighty patients with 54 aortic and 26 aortoiliac (7 juxtarenal, 1 suprarenal + renal graft) aneurysms underwent surgery. Seventy eight were male with a median age of 72 years (IQR 67-75). Forty seven patients had laparoscopic assisted and 33 had total laparoscopic surgery. Median aortic clamp time was 85 minutes (IQR 75-120) with an operative time of 330 minutes (IQR 300-390). Epidural requirement was 1 day (range 0-3); time to solid diet was 1 day (range 1-6) and time to mobilisation was 1 day (range 1-4). Postoperative stay was 5 days (IQR 3-7). Early complication rate was 19% and 30 day mortality rate was 1.3%. Follow-up at 5 years showed 4 late but no graft-related complications.

Conclusion: 
Laparoscopic aneurysm surgery was performed with a low perioperative mortality and good early durability.  Operative times were long, epidural usage was limited, recovery of gut function and mobility was early and length of stay was short.

Aims: Identification of risk factors for prolonged healing and early recurrence is vital to identify a high risk population who may benefit from early intensive treatment.

Methods: Data were collected from a prospective database over a 16 year period under a specialist leg ulcer service. Kaplan-Meier survival analysis calculated 24 week healing and 12 month recurrence rates. Risk factors were assessed using cox regression multivariate analysis.

Results: Overall 24 week healing was 79% increasing from 63% (1995-98) to 81% (2007-10) over the study period (p<0.01). The twelve month recurrence rate decreased from 20.1% (1995-8) to 13.5% (2007-10) with an overall rate of 19% (p<0.01). Eighteen risk factors were identified for analysis. Rheumatoid arthritis was an independent risk factor for prolonged healing (p<0.01). The range of ankle movement was independently associated with an increased risk of early recurrence (p<0.05).
Poor mobility, ulcer size and chronicity were all associated with both prolonged healing (p<0.01, <0.01, <0.01) and early recurrence (p<0.01, <0.01, <0.05).

Conclusions: Poor mobility, ulcer size and ulcer chronicity are all associated with a poor outcome.
