AI Technical Summary
Existing methods for stopping bleeding from a gunshot wound to an artery are invasive and cause additional trauma, complicating surgical access and leading to complications like blood loss and hypoxia, while also risking thrombosis due to intimal layer detachment.
A minimally invasive method using angiography to locate the arterial defect, inserting a stent, inflating a balloon within the stent to deliver a hemostatic agent through a wound channel, and applying a pressure bandage after tamponade, under X-ray control.
This approach minimizes trauma and prevents long-term complications by effectively controlling bleeding and preventing thrombosis, as demonstrated by successful hemostasis in a clinical example.

Abstract
Description
[0001] The invention relates to medicine, namely to X-ray surgical methods of diagnosis and treatment, and makes it possible to stop bleeding in a gunshot wound to an artery.
[0002] A gunshot wound to an artery, in addition to damaging the vessel itself, also causes destruction of adjacent tissue, resulting in hematoma formation. This complicates surgical access to stop bleeding and is accompanied by unnecessary trauma to the patient and the development of possible complications, including additional blood loss. Furthermore, due to the impact of the shock wave, in addition to the visible defect in the arterial wall, there is always damage to the vessel along its length, in the form of detachment of the intimal layer, which can subsequently lead to thrombosis.
[0003] The classic method of stopping bleeding in such cases involves open surgical access to the injured vessel with dissection of the surrounding tissues, followed by suturing the wound defect, which is always accompanied by additional trauma and, as a consequence, a number of complications (blood loss, hypoxia, etc.).
[0004] The invention is based on the task of creating a minimally invasive, non-traumatic method for stopping bleeding from a damaged artery while preventing long-term complications.
[0005] The solution to the problem is ensured by the fact that in the method of stopping bleeding from a gunshot wound to the arteries, angiography is performed to determine the location of the defect in the arterial wall, then a stent is inserted into the lumen of the artery and implanted, then a balloon is inflated in the lumen of the stent and through the wound channel under X-ray control, focusing on the inflated balloon, using a thin clamp, a hemostatic agent is delivered to the site of the arterial defect and tamponade is performed at the site of the wound channel, after which the balloon is removed, a pressure bandage is applied and angiographic control is performed.
[0006] The invention is illustrated by Fig. 1, which shows angiography being performed to determine the location of a defect, where the arrow indicates a cloud of contrast agent entering through a wound defect in the arterial wall; Fig. 2 shows an implantable stent, indicated by an arrow; Fig. 3 shows how a hemostatic material is delivered to the location of the arterial defect through a wound channel using a clamp; Fig. 4 shows a control angiogram.
[0007] The invention is implemented as follows. Angiography is performed to determine the location of the arterial wall defect (Fig. 1, where the cloud of contrast agent is indicated by the arrow). A stent, shown by the arrow in Fig. 2, is inserted into the lumen of the artery and implanted. The stent acts as a frame, preventing the artery from collapsing during further manipulations and eliminates detachment of the intimal membrane, thus preventing intra-arterial thrombosis (Fig. 2). After installing the stent, a balloon is inflated in its lumen for greater radial support and, under X-ray control, using the inflated balloon as a guide, a hemostatic agent (for example, a hemostatic sponge) is delivered to the site of the arterial defect using a thin clamp and the wound channel is tamponaded (Fig. 3). After which the balloon is removed and a pressure bandage is applied. Angiographic control is performed, and if hemostasis is successful, the procedure is completed (Fig. 4).
[0008] Clinical example
[0009] Patient R., 28 years old, was admitted with a shrapnel wound in the left subclavian region. Diagnostic tests revealed a subclavian artery injury with ongoing bleeding. Given the patient's serious condition, a decision was made to abandon open surgery and perform endovascular intervention. The first step was subclavian artery angiography, which confirmed the subclavian artery lesion and visualized the vessel wall defect (Fig. 1). Stenting of the subclavian artery was performed (Fig. 2), a balloon was inserted into the implanted stent, and a hemostatic sponge was delivered to the site of the vessel wall defect using a button probe (Fig. 3). The balloon was then removed, and control angiography visualized successful hemostasis at the wound site (Fig. 4).
