Though ulnar arterial variations are rare, superficial ulnar artery (SUA) is one of its commonest variations. During routine dissection in our department, we observed a unilateral case of SUA in a 70-year-old male human cadaver. It originated from the left brachial artery in the middle of the arm, 13cm above the medial epicondyle of humerus (15cm below the outer margin of first rib). From its origin, it passed downwards in the medial part of arm and forearm in a superficial plane compared to normal ulnar artery. In the hand, the SUA anastomosed with the superficial palmar branch of the radial artery, creating the superficial palmar arch. The superficial palmar arch gave additional branches to the thumb and index finger. Brachial artery divided into the radial and common interosseous arteries in the cubital fossa. The normal ulnar artery was absent. The existence of a SUA is undeniably of interest to the clinicians as well as to the anatomists. We hereby present a case of unilateral SUA along with a brief review of the literature and analysis of its clinical significance.

Facial vein is the main vein of the face. Though its origin is constant, it frequently shows variations in its termination. We report a rare type of variation of facial vein. The right facial vein coursed transversely across the masseter, superficial to the parotid duct and entered into the substance of the parotid gland, at its anterior border. Deep dissection of the gland revealed the abnormal termination of facial vein into the superficial temporal vein. The transverse facial vein drained into the facial vein. The superficial temporal vein after receiving the facial vein continued as retromandibular vein. Knowledge of this anomalous course and termination of facial vein may be important for the surgeons doing parotid, maxillofacial and plastic surgeries.

Awareness of anatomical variations in lungs is essential during segmental or lobar resections of lungs. We studied the variations of fissures, lobes and hilar structures in 65 right and 73 left isolated lungs from the dissection hall. Horizontal fissure was absent in 3.07% and incomplete in 35.38% of right lungs. Four point six one percentage of right lungs had 3 fissures and 4 lobes. Three point zero seven percentage of right lungs had 3 arteries, 67.69% had 2 arteries, and 29.23% had only one artery in the hilum. Sixty-three point zero seven percentage of right lungs had two veins in the hilum; 32.30% had 3 veins in the hilum; and 4.61% had more than 3 veins in the hilum. Ninety-eight point four six percentage of right lungs showed 2 bronchi in the hilum, and 1.53% of them showed 3 bronchi in the hilum. Two of the right lungs (3.07%) had an artery passing across the oblique fissure. Fifteen point zero six percentage of left lungs showed incomplete oblique fissure and 2.73% showed 2 fissures and 3 lobes. Five point four seven percentage of left lungs showed 2 arteries and 94.52% had only one artery in the hilum. Eighty point eight two percentage of left lungs had two veins in the hilum and 19.17% had 3 veins in the hilum. Twenty-one point nine one percent of left lungs had 2 bronchi and 78.08% had only one bronchus in the hilum. The knowledge of variations in the lobar and hilar anatomy of the lung presented in this study is clinically important while interpreting the radiological images and performing surgical procedures.

Purpose: Indians have a higher incidence of cardiovascular diseases, often at a younger age, than other ethnic groups. This higher baseline risk requires consideration when assessing additional cardiac morbidity of breast cancer treatment. Superior cardiac sparing is a critical dosimetric advantage of proton therapy in breast cancer radiotherapy. We report here the heart and cardiac-substructure doses and early toxicities in breast cancer patients treated post-operatively with proton therapy in India’s first proton therapy center. Materials and Methods: We treated twenty breast cancer patients with intensity-modulated proton therapy (IMPT) from October 2019 to September 2022, eleven after breast conservation, nine following mastectomy, and appropriate systemic therapy, when indicated. The most prescribed dose was 40 GyE to the whole breast/chest wall and 48 GyE by simultaneous integrated boost to the tumor bed and 37.5 GyE to appropriate nodal volumes, delivered in 15 fractions. Results: Adequate coverage was achieved for clinical target volume (breast/chest wall), i.e., CTV40, and regional nodes, with 99% of the targets receiving 95% of the prescribed dose (V95% > 99%). The mean heart dose was 0.78 GyE and 0.87 GyE for all and left breast cancer patients, respectively. The mean left anterior descending artery (LAD) dose, LAD D0.02cc, and left ventricle dose were 2.76, 6.46, and 0.2 GyE, respectively. Mean ipsilateral lung dose, V20Gy, V5Gy, and contralateral breast dose (Dmean) were 6.87 GyE, 14.6%, 36.4%, and 0.38 GyE, respectively. Conclusion The dose to heart and cardiac substructures is lower with IMPT than published photon therapy data. Despite the limited access to proton therapy at present, given the higher cardiovascular risk and coronary artery disease prevalence in India, the cardiac sparing achieved using this technique merits consideration for wider adoption in breast cancer treatment.

Tensor fasciae suralis, also known as ischioaponeuroticus is a clinically relevant muscle variant located in the popliteal fossa. Though rare, when present the muscle may arise from any of the hamstrings and gets inserted to the crural fascia of leg or tendocalcaneus and is innervated by the tibial component of sciatic nerve. Here we report a variant of tensor fasciae suralis originated from the lowermost part of linea aspera along with the fibers of short head of biceps femoris in the left lower limb of a male cadaver aged approximately 58 years. The muscle was 16 cm in length and 1 cm breadth in its widest part. It was found inserted to the crural fascia over the lateral head of gastrocnemius and was found innervated by common peroneal nerve. To the best of our knowledge, the tensor fascia suralis muscle originated from linea aspera along with short head of biceps femoris and innervated by common peroneal nerve has not been reported in either cadaveric or imaging studies.
