Is endovenous laser ablation possible while taking warfarin?

Purpose: The subgroup of patients with venous ulcers requiring anticoagulation for co-morbid conditions has traditionally created a therapeutic dilemma. Perioperative management of anticoagulation can be costly and increase the risk of surgical complications. This group of patients is often elderly and shows poor compliance with compression hosiery.

Critical assessment of the outcome of infrainguinal vein bypass.

Objective: To perform a more critical assessment of infrainguinal vein bypass.

Summary Background Data: Graft patency may give an unrealistic impression of the outcome of bypass surgery.

Methods: During a 6-year period, 236 patients undergoing primary vein grafts were entered into the study.

Vascular outflow resistance and angiographic assessment of lower limb arterial reconstructive procedures.

In an attempt to predict early graft occlusion secondary to poor distal run-off, the outflow resistance was measured intra-operatively and compared with the intra-operative angiogram in 50 patients undergoing lower limb bypass procedures. With arterial inflow occluded, 60 mL of plasmalyte was infused via a catheter and the resultant pressure generated in the graft was measured through a second catheter connected to a pressure transducer and recorder. Using the infusion rate and integrated pressure value, outflow resistance was calculated.

Gall-bladder and sphincter of Oddi response to cholecystokinin in the Australian possum.

The effects of cholecystokinin octapeptide (CCK-OP) on the gall-bladder (GB) and sphincter of Oddi (SO) of the Australian brush tailed possum were examined in 45 anaesthetized animals. CCK-OP (20-640 ng/kg) consistently caused the GB to contract in a dose-dependent manner (Kruskal Wallis P less than 0.05).

Human fasting and postprandial sphincter of Oddi motility.

Sphincter of Oddi motility was evaluated in post-cholecystectomy patients with indwelling T tubes during fasting and after feeding. A triple-lumen catheter was positioned to record from the sphincter of Oddi and duodenum. The sphincter of Oddi was characterized by phasic contractions independent of duodenal contractions.
