Introduction: Obturator artery is the branch of anterior division of internal iliac artery. Variations in its origin are quite common and are very important from surgical point of view. Methods: To study the variations in the origin of the obturator artery 35 dissected vessels were studied. Results: Commonest variation of its origin from the posterior division of internal iliac artery was found in five cases. Other variations like its origin from internal pudendal artery or from inferior gluteal artery were also found, which are also discussed along with its embryological basis and clinical significance. Conclusions: Knowledge of anomalous origin of obturator artery from posterior division is helpful to vascular surgeons while planning endovascular treatment.

William Hunter is credited with the earliest description of an arteriovenous fistula (AVF) when he noticed an abnormal connection between an artery and a vein in two patients who underwent a phlebotomy. After the 19 ^th century with the advent of high-speed projectiles, the incidence of AVF increased. With a better understanding of the underlying pathophysiology, the modalities of diagnosis and treatment have come a long way and even now continue to change. We present below three patients who presented with AVF and were treated with surgery.

The occurrence of aortic dissection involving a right-sided aortic arch (RAA) is extremely rare. Majority of the symptomatic cases have been managed with open surgical treatment. However, middle-aged and elderly patients with coexistent comorbidities have higher postoperative risks if managed by surgery. The purpose of this case study is to review the literature for occurrence and treatment modalities for RAA with dissection, to review the various literature studies which have helped establish a consensus and guidelines in the management of aortic dissections, to review previous reported cases of successful endovascular management of RAA dissections, and to report our experience of treating a case of Stanford Type B right-sided aortic dissection managed by complete endovascular approach, the first of its kind in India. Our search in the databases revealed around 32 cases of RAA with aortic dissection published in the literature, most of which have been treated with open surgical approach; however, very few cases are managed with endovascular approach only like in our case.

Profunda femoris artery pseudoaneurysms (PFAPs) have been described as an iatrogenic phenomenon, principally following orthopedic procedures and open or closed trauma to the upper thigh, although remain rare. The diagnosis of PFAPs is challenging and often delayed due to the nonspecific manner of the presentation with clinical features including pain, swelling, and unexplained anemia as demonstrated in this case report of a PFAP following a stab injury to the thigh. The use of computed tomography angiography (CTA) or transcatheter angiography allows for early accurate diagnosis and treatment of vascular complications secondary to trauma, especially when there is concern of vascular injury and possible pseudoaneurysm formation in the clinical context.

Aneurysm of the foot is rare. These aneurysms are diagnosed based on clinical examination and angiogram. The treatment protocol was based on the angiogram, and the culture examination of the specimen will definitely have a role to play in the overall management of the patient.

Missed guidewire is a rare and potentially avoidable complication of central venous cannulation. Unsupervised insertion by trainees, distraction during insertion, and high workload may increase the risk. Simple measures such as holding onto the wire at all times until removal from the vessel, routine use of central venous catheter insertion checklist, and vigilant supervision of the trainees may help prevent missing of the guidewire.

True aneurysms of the superficial temporal artery are extremely rare. The majority of these aneurysms are a consequence of trauma. A 56-year-old male noticed a swelling in front of his left ear, which had slowly increased in size. There was no history of trauma. Computed tomography revealed an aneurysm of the main trunk of the superficial temporal artery. A ligation and excision was performed. The postoperative period was uneventful. Histology revealed a true aneurysm.

Early diagnosis and treatment of hypothenar hammer syndrome are important to prevent thrombosis, distal embolization, or hand claudication. We report a case of rare presentation of misdiagnosed ulnar artery aneurysm, which was inadvertently incised as an infected hematoma.
