Medical College, Nagpur, Maharashtra Corresponding Author: Dr. Surekha W. Meshram Abstract Introduction: Veins of lower limbs are more involves for various venous disorders as compare to upper limbs. Most common venous disorders occurring in lower limbs are varicose veins, deep venous thrombosis and venous ulcers. Varicose veins are found in large population of world affecting both the males and females. Surgical operations are performed in all over the world to cure it. In the varicose vein surgery, surgeon successfully do the ligation as well as stripping of the great saphenous vein and its tributaries. Duplication of a great saphenous vein can be a potential cause for recurrent varicose veins after surgery as well as complications may occur during the surgery. Method: The present study was done by dissection method on 50 lower limbs of cadavers. Its aim was to identify the incidence and pattern of duplication of long saphenous vein in Indian population.

  • The Femoral Hernia: Some Necessary Additions
    International Journal of Clinical Medicine, 2014, 5, 752-765 Published Online July 2014 in SciRes. http://www.scirp.org/journal/ijcm http://dx.doi.org/10.4236/ijcm.2014.513102 The Femoral Hernia: Some Necessary Additions Ljubomir S. Kovachev Department of General Surgery, Medical University, Pleven, Bulgaria Email: [email protected] Received 28 April 2014; revised 27 May 2014; accepted 26 June 2014 Copyright © 2014 by author and Scientific Research Publishing Inc. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Purpose: The anatomic region through which most inguinal hernias emerge is overcrowded by various anatomical structures with intricate relationships. This is reflected by the wide range of anatomic interpretations. Material and Methods: A prospective anatomic study of over 100 fresh cadavers and 47 patients operated on for femoral hernias. Results: It was found that the transver- salis fascia did not continue distally into the lymphatic lacuna. Medially this fascia did not reach the lacunar ligament, but was rather positioned above it forming laterally the vascular sheath. Here the fascia participates in the formation of a fossa, which varies in width and depth—the pre- peritoneal femoral fossa. The results did not confirm the presence of a femoral canal. The dis- tances were measured between the pubic tubercle and the medial margin of the femoral vein, and between the inguinal and the Cooper’s ligaments. The results clearly indicate that in women with femoral hernias these distances are much larger. Along the course of femoral hernia exploration we established the presence of three zones that are rigid and narrow.

E-mail: [email protected] ……………………………………………………………………………………………………………………………...… Abstract Objective: Femoral vessels are one of the frequently used sites of cannulation in intensive care units. In resource limited settings cannulations are done blindly without ultrasonographic guidance based on a traditional belief that in the upper thigh vein keeps a medial relationship to artery. In this trial we tried to analyse the anatomical relationship of femoral vein to femoral artery using ultrasound in critically ill patients. Methods: This cross sectional study analysed the anatomical relationship of femoral vein to femoral artery at 2cm, 4 cm and 6 cm from the mid inguinal point in both thighs of the patients using ultrasonography. The study was done among patients admitted in a multidisciplinary intensive care unit. Results: Three hundred limbs of one hundred and fifty patients were analysed by ultrasonography. A total of 900 measurements were taken at three different levels of both legs.

The femoral triangle is located on the anterior aspect of the thigh, inferior to the inguinal ligament and knowledge of its contents has become increasingly more important with the rise in use of the Smith-Petersen Direct Anterior Approach (DAA) to the hip as well as ultrasound and fluo- roscopic guided hip injections. A detailed knowledge of the anatomical landmarks can guide surgeons in their anterior approach to the hip, avoiding iatrogenic injuries during various procedures. The novel mnemonic “NAVIgate” the femoral triangle from lateral to medial will aid in remembering the borders and contents of the triangle when performing surgical procedures, specifically the DAA.
