Patterns of venous reflux in limbs with venous ulcers. Implications for treatment.

AIM: To investigate the anatomic distribution of vein reflux in limbs with healed or active ulcers (CEAP V and VI). METHODS: Sixty limbs (58 patients) belonging to CEAP classes V and VI were identified from 798 limbs (519 patients) with ultrasonically proven chronic venous insufficiency (CVI). Age, gender, duration of the venous ulcer, and history of deep venous thrombosis were correlated to the anatomic distribution of the venous reflux. RESULTS: The prevalence of active or healed ulcers in limbs with CVI was 7.5%. Among 60 limbs with ulcers, primary CVI was present in 34 (56.7%) and post-thrombotic CVI in 26 limbs (43.3%). No difference in age and gender was found between the 2 groups (p=0.2 and p=0.8, respectively). However, the duration of the ulcer was longer in limbs with post-thrombotic CVI (p<0.05). The prevalence of perforator reflux was 41.2% (14/34) in limbs with primary CVI and 38.5% (10/26) in limbs with post-thrombotic CVI (p=0.8). Superficial venous insufficiency, with or without perforating vein reflux, was the commonest pattern in limbs with primary CVI; it was rare in limbs with post-thrombotic CVI (22/34 or 64.7% vs 2/26 or 7.7%, p<0.01). Deep vein insufficiency was present in 35.3% (12/34) of the limbs with primary CVI and in 92.3% (24/26) of the limbs with post-thrombotic CVI (p<0.01). CONCLUSION: Superficial venous insufficiency, with or without perforating vein reflux, was the commonest pattern in limbs with primary CVI, whereas, deep venous insufficiency was present in most of the limbs with post-thrombotic CVI. The prevalence of perforating vein reflux was comparable in both settings. Thus, elimination of superficial reflux is expected to result in ulcer healing of most limbs with primary CVI, whereas, the value of such treatment in post-thrombotic limbs is not clear.     

The evolution of lower limb amputation through the ages. Historical note.

The aim of this study was to highlight the important stages of the evolution of limb amputation through the ages through the search of the relevant international literature. Limb amputation is one of the most serious surgical operations, which is associated with high mortality and morbidity. Evidence regarding the execution of limb amputation can be found back in Neolithic times. The most important steps in the evolution of the technique of limb amputation were made in the 16th, 17th, and 18th centuries when A. Pare' introduced the vessel ligation and the French barber surgeon Morell introduced the use of a tourniquet to reduce the bleeding. During the same period, from the 'one-stage circular cut' the technique evolved to either 'three-stage circular cut' or to 'flap amputation', single or double. Limb amputation represents one of the oldest and most serious surgical operations. Its evolution parallels the maturation process of surgery, with the major developments in the technique to have been made from the 16th to the 18th century. In the beginning of the 21st century, limb amputation appears to be a safe operation ending up with a functional stump.     

Experience with New Techniques for Extraanatomic Arterial Reconstruction of the Lower Limb

The aim of this report is to present our experience with new techniques for extraanatomic lower limb arterial reconstruction. Two techniques are described here of construction of an extraanatomical bypass for lower limb revascularization either through the wing of the iliac bone or underneath the iliopsoas fascia through the muscular lacuna close to the anterior superior spine of the iliac crest. Both techniques are recommended for the treatment of a severely injured groin, such as in patients with pelvic malignancy and/or an acute groin bleeding due to postirradiation femoral artery erosion or an infected femoropopliteal bypass graft with severe upper medial thigh sepsis. These techniques were used in nine patients (five with malignancy and four with an infected femoropopliteal bypass graft). Our results showed that the transosseous route through the wing of the iliac bone or underneath the iliopsoas fascia through the muscular lacuna may be considered effective alternate routes for lower limb arterial extraanatomic reconstruction when the common femoral cannot be used for arterial inflow.     

Reflections of the Hippocratic Oath in Modern Medicine

Hippocratic Oath indicates a prevailing ethos rather than a professional approach, and it is still regarded as the cornerstone and foundation of the medical profession. Medicine in Ancient Greece was strongly influenced by the values of classical philosophy as introduced by its main representatives: Plato and Aristotle. Hippocrates himself has been recognized not only as a pioneering physician, but also as an outstanding philosopher. In his writings, he claimed that “the physician must insert wisdom in medicine” and denounced the technocratic aspect of the medical profession. The Hippocratic Oath constitutes a synopsis of the moral code of Ancient Greek medicine and contributes to the stabilization of the tri-part relationship among the physician, the patient, and the illness, as described by Hippocrates. The harmony of this interactive triangle has been deranged by several factors, such as technological evolution, public media, and cost-effective modalities with multiple consequences. In these terms, the reevaluation of the Hippocratic Oath and its time-enduring messages seems essential to reinstate the relationship between the physician and the patient under a new philosophico-medical prism.
