INTRODUCTION: Deep knowledge of anatomy is an essential part of surgical practice. Students of medical sciences gain knowledge and theoretical data through actual visualization of anatomic structures of the cadavers also anatomic relations can be studied more efficiently by practicing on cadavers. As phrenic nerve may be damaged during subclavian vein catheterization the relationship between the phrenic nerve and the subclavian vein is of clinical interest. During the subclavian vein catheterization analogous variable relationships are helpful to explain and prevent damage to the phrenic nerve. MATERIAL AND METHODS: Dissection was started from the root of the neck. No surgical scars, gross anatomical and morphological abnormalities was noted on the cadaver. Measurements were taken during the anatomical dissections.  RESULTS: Of the 36 cadavers dissected in 34 (94.44%) cases phrenic nerve was found posterior to the subclavian vein and in 2(5.56%) cases found anterior to the subclavian vein of which one case was male and the other was female. In the male case in which phrenic nerve was passing anterior to the subclavian vein, it was adherent to the anterior wall of the subclavian vein and was nor piercing the vein wall. CONCLUSION: The cannulating needle may damage the phrenic nerve which is adherent to the subclavian vein. So, the puncture site should be more laterally at the outermost portion of the subclavian vein. Anatomical variants during invasive practical procedures should be always kept in mind.

Vein Catheterization

Introduction: Central vein catheterization can be introduced in subclavian vein (SCV), internal jugular vein or femoral vein for volume resuscitation and invasive monitoring technique. Due to anatomical advantage and lesser risk of infection subclavian vein is preferred. Either supraclavicular (SC) or infraclavicular (IC) approach could be used for subclavian vein catheterization. The aim of the study was to compare SC and IC approach in ease of catheterization of SCV and record the complications present if any. Methods and materials: This was a hospital based comparative, interventional study conducted from November 2016 to October 2017 in Operation Theater in Bir Hospital. In this study, 70 patients for elective surgical cases meeting the inclusion criteria were randomly enrolled. Then samples were equally divided by lottery into either supraclavicular or infraclavicular approach groups. The Access time, cannulation success rate, attempts made for successful cannulation of vein, easy insertion of catheter and guide wire, approximate inserted length of catheter and associated complications in both groups were recorded. Data was entered in statistical software SPSS 16. Chi-square test was used. P value < 0.05 was considered significant. Results: The mean access time in group SC for SCV catheterization was 2.12 ± 0.81 min compared to 2.83 ± 0.99 min in group IC (p-value= 0.002). The overall success rate in catheterization of the right SCV using SC approach (34 / 35) was better as compared with group IC (33 / 35) using IC approach. First successful attempt in the SC group was 74.28% as compared with 57.14% in the IC group. Conclusion: The SC approach of SCV catheterization can be considered alternative to IC approach in terms of landmark accessibility, success rate and rate of complications.

Landing Zone

Introduction: Thoracic Endovascular Aortic Repair (TEVAR) has become the procedure of choice for pathology involving the descending thoracic aorta since its approval by the FDA in 2005. Left subclavian artery (LSA) coverage is commonly required to facilitate an adequate proximal landing zone for the endograft. The traditional revascularization procedure of choice is carotid-subclavian bypass, however recent studies report complication rates as high as 29%—specifically phrenic nerve palsy in 25% of patients undergoing this procedure. Our aim is to present our experience using carotid-axillary bypass as a safe alternative to carotid-subclavian bypass. Methods: All patients undergoing carotid-axillary bypass for TEVAR with LSA coverage between June 2016 and September 2019 at a tertiary medical center were retrospectively identified. Short-term and long-term complications were identified and analyzed including: phrenic nerve, recurrent laryngeal nerve, and axillary nerve injuries, as well as local vascular complications requiring re-intervention. All perioperative chest radiographs were reviewed for new hemidiaphragm elevation to assess for phrenic nerve injuries. Results: 35 patients underwent carotid-axillary bypass in conjunction with TEVAR during this time period. The majority of bypasses were performed concurrently with TEVAR (80.0%, 28/35) utilizing GORE PROPATEN 8 mm externally supported vascular graft (91.4%, 32/35). The complication rate specific to carotid-axillary bypass was 14.3% (5/35). We observed a significantly lower (0%, 0/35, P < 0.01) rate of phrenic nerve palsy for carotid-axillary bypass compared to the previously reported 25% (27/107) for carotid-subclavian bypass. For patients with available follow-up imaging (85.7%, 30/35), there was a 100% patency rate at time intervals ranging from 0-1066 days (IQR = 3-37.8). Conclusion: Carotid-axillary bypass can be performed as a safe alternative to carotid-subclavian bypass for LSA coverage during TEVAR involving a more superficial anatomic course of dissection. Phrenic nerve palsy, a well-described complication of the traditional carotid-subclavian bypass, was not observed in this retrospective series.
