Abstract
BACKGROUND
Due to shortage of local donor tissue and unreliable blood supply, free flaps were the mainstay of treatment for tissue defects in the lower leg and foot region, but it requires a qualified microvascular surgeon. Recently, attention has been paid to reverse superficial sural artery flap (RSSAF) and its modifications as a good alternative to pave the way to simple and friendly techniques.
METHODS
Excluding each patient with septic and severely ischemic foot, every patient with tissue defect in distal leg and proximal foot region were studied. Various methods were applied including spout technique with sufficient follow up. No imaging was used to evaluate the blood supply.
RESULTS
Five patients underwent spout technique with excellent results in four cases. Spout technique in one case failed due to narrow base. In five cases, RSSAF was performed with creating skin tunnel and very good results.
CONCLUSION
RSSAF is a good alternative for free flap to cover the leg and foot tissue defects. We also advise wide base pedicle (>4 cm) in every patient.

Abstract
BACKGROUND
Free Flaps are viable option to cover the tissue defect. Pedicle anastomosis to vessel branches has excellent result. In some situations which there is a possibility of flap failure like shortage of vessel branches, possibility of pedicle kinking or need to vein graft, anastomosis to great vessels is justified.
METHODS
Six patients were allocated to study. Five cases for free jejunal flap and one case for free latissimus flap. In free jejunal flap group, pedicle anastomosis was performed as an end-side fashion to common carotid artery and internal jugular vein and in free latissimus flap, pedicle was anastomosed as an end-side fashion to superficial femoral artery and superficial femoral vein. Follow up was regular up to 20 years.
RESULTS
In free jejunal flap group, there were three female and two male with age from 30 to 59 years. The sixth case was a thirteen years old male with flexion contracture of right knee who underwent free latissimus flap. Follow up was regular for 20 years. All flaps survived, and good functional result was obtained in all except one.
CONCLUSION
Choosing great vessels as one side of anastomosis is safe and can be done as a primary approach due to technical demand or as a final resort when there is shortage of side branches.

Abstract
Background: Retrorectal tumors are rare, heterogeneous neoplasms in the pararectal space that have low incidence, nonspecific symptoms, and variable presentations; they are often challenging to diagnose and manage, necessitating high clinical suspicion. We evaluated the clinical characteristics, diagnostic challenges, surgical outcomes, and postoperative follow-up of patients with retrorectal tumors treated over 12 years.
Methods: A retrospective case series was conducted on 34 patients who underwent surgery for retrorectal tumors at Taleghani Hospital, Tehran, Iran, from 2011 to 2023. Clinical presentations, imaging findings, surgical interventions, histopathological diagnoses, and postoperative outcomes were analyzed.
Results: Thirty-four patients with 37 lesions were included, with a mean age of 40.21 ± 11.57 years. The majority of patients were female (88.2%). Pelvic pain was the most common symptom (44.1%), followed by rectal pain (38.2%). The retrorectal space was the most frequently affected location (67.6%). Most tumors were cystic (51.4%), with congenital tumors being the most common histopathological subtype (37.8%). Malignancy was identified in 29.7% of cases. The most frequent surgical approach was total resection via the posterior approach (55.9%), followed by the anterior approach (26.5%). Postoperative recurrence requiring secondary surgery was observed in 5.9% of patients.
Conclusion: Due to their rarity and diverse presentations, retrorectal tumors pose significant diagnostic and surgical challenges. Preoperative imaging plays a critical role in diagnosis and surgical planning. Complete surgical excision remains the mainstay of treatment, and recurrence is rare. Multidisciplinary collaboration is essential for optimizing patient outcomes.
