Endovenous laser ablation (EVLA) and radiofrequencey ablation have become the procedures of choice for the treatment of superficial venous insufficiency. Their minimally invasive technique and safety profile when compared with operative saphenectomy have led to this change. As EVLA has replaced saphenectomy as the procedure of choice, the distribution of complications has changed. We evaluated the most common and most devastating complications in the literature including burns, nerve injury, arterio-venous fistula (AVF), endothermal heat-induced thrombosis and deep venous thrombosis. The following review will discuss the most frequently encountered complications of treatment of superficial venous insufficiency using EVLA. The majority of the complications described can be avoided with the use of good surgical technique and appropriate duplex ultrasound guidance. Overall, EVLA has an excellent safety profile and should be considered among the first line for treatment of superficial venous reflux.

Acute mesenteric ischemia is caused by a critical reduction in intestinal blood fl ow that frequently results in bowel necrosis and is associated with a high mortality. Clinicians must maintain a high index of suspicion because a prompt diagnosis and early aggressive treatment before the onset of bowel infarction results in reduced mortality. Medical management includes aggressive rehydration and the use of antibiotics, anticoagulation, vasodilators, and inhibitors of reperfusion injury. If acute mesenteric ischemia is suspected, early angiography is imperative, as it permits accurate diagnosis and possible therapeutic intervention. Therapeutic options during angiography depend on the cause of ischemia and include administering intra-arterial vasodilators and/or thrombolytic agents and angioplasty with or without stent placement. If interventional techniques are not possible or if the patient presents with suspicion of bowel infarction, surgery is warranted. Surgical techniques include superior mesenteric artery embolectomy or visceral artery bypass, which should be used before bowel resection to ensure only resection of nonviable bowel.
