RESUMO
Objectives: To document the Outcomes of AV fistula formation for dialysis patients using interrupted sutures. Methods: In this Cross-sectional study conducted at PNS Shifa Karachi, from June 2022 to June 2023, patients above 18 years of age, male or female, with ESRD/CKD were included. After clinical screening and ultrasound doppler, the distal most part of wrist was considered as a site for radio cephalic AVF. Operation was performed under surgical loupe with 4.5x magnification. Standard incision of about 4-5 cm oblique proximal to the wrist crease was given at the volar surface on the radial side of Distal forearm, extending till the lateral side up to the snuffbox. Subcutaneous tissue was incised and dissection was done to identify the cephalic vein and radial artery. Distal most end of the cephalic vein was ligated using vicryl 4-0 suture and cephalic vein dissected free from the underling tissue to mobilize it up to the radial artery. Results: During the study N=35 patients who required AVF creation visited the department. The mean age of the study participants was 59.34±15.48. If thrill at the site of AVF and backflow at cut end of cephalic vein were present the surgeons were satisfied, higher satisfaction among the surgeon was achieved in the AVF created at brachiocephalic artery while the diameter of vessels didn't contribute in surgeon satisfaction. Conclusion: Presence of thrill at the site of AVF and backflow at cut end of cephalic vein have strong association with good prognosis of AVF.
RESUMO
BACKGROUND: Reconstruction of defects around the knee and proximal leg are difficult to reconstruct. Out of the multiple flaps described for reconstruction, the pedicled Medial Sural Artery Perforating Flap (MSAP) has recently gained popularity. We conducted this study to assess the clinical outcomes of pedicled MSAP for this purpose at our hospital. METHODS: A descriptive case series was conducted from April 2022 to March 2023. All patients above 18 years with defects around the knee and proximal leg were included. Patients with tissue loss in the calf area were excluded. RESULTS: A total of 14 patients were included. Twelve (86%) were males, while only 2 were females (14%). The mean age was 33.5 years (±8.76). The most common cause of the defect was trauma (n=11, 85%). The Mean distance of the distal-most perforator from the popliteal crease was 12.714 (±1.990) cm (range 9-16 cm). It was observed that the most distal perforator is usually present in a 2 cm radius of the medial musculo-tendinous junction of the gastrocnemius. Complications were seen in 2 (14%) patients. The mean duration of hospital stay was 4.2 (±0.96) days. Patients were followed up weekly for the first two weeks and then at 1, 3 and 6 months. CONCLUSIONS: MSAP Flap is a reliable thin, long pedicled fasciocutaneous flap with low donor site morbidity and aesthetically good results for reconstruction around the knee and proximal leg.
